Estimating productivity gap and contribution of wheat productionsanaullah noonari
Shaheed Benazirabad farmers were divided into groups named high yield group, medium yield group and low
yield group. The farmers applied an average of 45.27 kg, 45.82 kg and45.18 kg seed per acre respectively.
Though, there is not a very large difference in average seed used by both farmer groups but the later used less
quantity of wheat seed per acre to some extent. The impact of different factors on these groups was measured
through multiple liner regression models. It was found that there exists a yield gap of 17.84 mounds per acre
between high yield group and research station. The yield gap between medium and high group was 8.02 Mds per
acre while the yield gap between medium group and low yield group was 5.93 Mds per acre. The standard error
of estimates F-statics and R-square for high yield group was 0.0623, 2.470 and 0.398 respectively, for medium
yield group 0.0314, 3.231 and 0.486 respectively and for low yield group 0.056, 1.342 and 0.345 respectively.
The other objective of the study was to calculate the growth rate of wheat in District Shaheed Benazirabad

- The production of pulses in Punjab has declined significantly over the past 40 years, from 308,000 metric tons in 1970-71 to just 17,000 metric tons in 2010-11. This is due to a sharp fall in the area allocated to pulses, from 414,000 hectares to just 20,000 hectares over the same period.
- Yield rates for pulses have increased but not enough to offset the large reduction in area. While Punjab's pulse yields are higher than the national average, production has grown at the national level but declined in Punjab.
- The shift to mono-cropping of wheat and rice following the Green Revolution has reduced crop diversification and crowded out pulses. Government policies and market
Model Increasing Productivity and Sustainability of Lowland Rice Farming in T...AI Publications
This study aims to analyze the structural model of the increase productivity and sustainability of rice farming in West Tanjung Jabung District. The data used are primary data obtained directly from farmers. The sample size used was 90 farmers. Sampling using simple random sampling method. The data analysis used the SEM Partial Least Square structural model. The results of the analysis show that the description of internal factors, external factors of farmers and the adoption of farming technology are in the medium category. The productivity and farming sustainability factors are in a low category. The determinant factor that greatly influences the productivity and sustainability of rice farming is farm income. Farm productivity and sustainability are significantly influenced by farmers 'access to credit, farmers' access to technology, and access to input procurement. The main determinant of productivity is the use of production inputs. The sustainability of farming is mainly determined by economic aspects, especially income. Models for increasing productivity and agricultural sustainability must pay attention to efforts to improve farmers' access to credit, access to technology and access to input procurement. Efforts are needed to handle the input output price for rice so that it can increase farmers' income.
Merauke as a food barn has been carried out since the days of the Dutch
administration, namely by making Merauke an Asia Pacific food warehouse. To
realize this target, the Dutch government conducted a program to move the
population known as colonization, namely by bringing residents from Java to be
moved to Merauke. After the independence period the Indonesian colonization
program was still held by the name of transmigration. These transmigrant farmers
then live side by side with local residents and transmit the ability to cultivate rice to
local residents in Merauke Regency who previously lived from gathering, shifting
fields, sago farming, fishing, hunting and farming with the method of lagging, finally

This research work examines the impact of technology adoption on agricultural productivity. It considers the south-west region of Bangladesh as the study area. Since most of the farmers in the study area are engaged in rice production, this study surveys randomly selected 60 rice farmers in the IRRI season of year 2015 through using a questionnaire. This study finds sufficient variation in frequency and degree of technology adoption in agricultural practices among the surveyed farmers. The analysis results indicate that farmers are adopting high level of technology in seed variety and irrigation phases, medium level of technology in land preparation, pest management and fertilizer application phases and low level of technology in weeding and harvesting phases. There is a statistically significant difference in productivity between high and low degree technology adopters. Education and land holdings are the statistically significant variables in determining technology adoption level. According to the study findings, a one percent increase in technology adoption leads to increase in productivity by 0.22 percent, holding other factors constant, and this influence is statistically significant at one percent level. Therefore, this study concludes that there is a scope for further increase in productivity through planned manipulation of technology adoption level in different phases of agricultural production.

Energy consumption pattern in wheat production in sindhsanaullah noonari
Wheat (Triticum aestivium L.) is the main staple food for most of the population and largest grain source o the
country. It occupies the central position in formulating agricultural policies. It contributes 13.1 percent to the
value added in agriculture and 2.7 percent to GDP. Area and production target of wheat for the year 2012-13 had
been set at 9045 thousand hectares and 25 million tons, respectively. Wheat was cultivated on an area of 8805
thousands hectares, showing a decrease of 3.6 percent over last year’s area of 9132 thousand hectares. However,
a bumper wheat crop of 24.2 million tons has been estimated with 3.9 percent increase over the last year’s crop
of 23.3 million tons. The prospects for wheat harvest improved with healthy fertilizer off-take and reasonable
rainfall during pre-harvesting period. Energy is a necessary of life for human beings all over the world due to its
function in strengthening the security and contentment of the people. Energy demand is growing with the
passage of time due to infrastructural and industrial development. Energy is required to perform all the human
activities. It is need for food preparation, water heating and cooling, for lighting, for production of goods etc.
The study was focused on all types of energy (fossil fuels, chemicals, animals dung, animate etc). A sample of
60 farmers was selected from study area. A pre tested questioner was used to collect data from selected
respondents through personal interviews. Descriptive statistics and Cobb-Douglas production function was
applied to analyze the data. Result shows that wheat farmer achieved highest amount of net energy which was
calculated as small, medium and large farmers is 1368336.88, 1698003.79 and1702527.75 MJ/acre respectively.
In production of wheat large, medium and small farmers achieve amount of net energy which was calculated
41525.06, 38590.99, 39095.33 MJ/acre. The impact of various energy inputs on yield was studied. The share of
various energy types in total cost of production was estimated. Commercial energy (diesel and electricity)
consumed highest amount of energy in production of wheat.

The research objectives achieved in this study were estimating the level of income
and feasibility of pulut uri organic farming in the District of Muting in Merauke
Regency. the type of research used is descriptive analytical research using basic data
from the results of previous studies, namely experimental research in organic
cultivation of uri corn. The basic data obtained is the data of organic uri corn on the
treatment of 0 tons / ha, 5 tons / ha, and 10 tons / ha of organic fertilizer. In this
study, identification of production, income and business feasibility costs will be
carried out using basic selling prices at the merchant level and at the end of the
consumer level. The data were analyzed by revenue, income / profit and feasibility
analysis of uri corn pulp. The results of the study concluded that with the selling price
of R. 3,000 / kg in the yield of pulverized corn, farmers would not get a large profit
with a feasibility rate of <1, which means that at that price level the farmers would
lose. Whereas with the selling price of Rp. 10,000 / kg of farmer's income will be
greater with the feasibility level> 1 which means that farmers will get profits or in
other words pulut organic corn farming can be developed in Merauke Regency
Analysis of technical Efficiency of traditional wheat farming in Fezzan regio...Premier Publishers
Although the efforts to enhance the productivity of wheat in Libya, it is still low and there is no improvement in wheat yield over the last decade indicating the usage of inputs in process of production is not efficient. Though some farms use modern methods in planting wheat, nevertheless a lot of wheat farmers are still using the traditional method of production. This paper aims to examine the technical efficiency of traditional wheat farming in Fezzan region, Libya as well as factors affecting technical inefficiency. A set of questionnaires was used to obtain data from 149 traditional wheat farmers selected by using a simple random sampling technique. The slack based data envelopment analysis model (SBM) was used to estimate technical efficiency and fractional regression model to determine factors response for inefficiency. Results showed that, the average technical efficiency of the farms was 0.69 indicating that farmers were operating at a low level of technical efficiency. This indicates that there is a need to improve technical efficiency by about 0.31 with the same level of inputs. The results of slack analysis revealed that the total inputs used by the traditional farmers would be reduced by 42 kg/ha for DAP, 58 kg/ha for seed, 14kg/ha for urea, 33 kg/ha for organic fertilizers and 12.9 man-days/ha for labour.

The results showed that, gain among different types of faming, increased quantum of feeding and increased body weight gain and daily average milk yield among the indigenous as well as cross breed animals.
This document summarizes a study that estimates output supply and input demand elasticities for rice production in Sri Lanka using a restricted normalized translog profit function approach. The study analyzes four major rice producing districts from 1990-2012. The results show that changes in input and output prices significantly affect farmer profits, rice supply, and input use. Rice supply elasticity with respect to price is 0.5, while fertilizer demand elasticity with respect to price is -0.05 on average. Fertilizer subsidy increases both fertilizer demand and rice supply. Low substitution elasticity between labor and fertilizer indicates complementary relationships that synergistically increase production when applied together. Overall, higher output prices are essential for greater rice production according to

In the current study, we have analyzed the contribution of agricultural sub-sectors growth rate to
the agriculture GDP growth rate of Pakistan by using secondary data from 2001 to 2015. Ordinary Least
Square (OLS) method was applied to estimate the model parameter. For this purpose the study considered a
dependent variable of agriculture GDP growth rate and several independents variables include major, minor
crops, livestock, fishery and forestry. The regression analysis of the data showed a positive and significant
contribution in agriculture GDP growth rate. However, fishery and forestry sub-sectors contribute growth rates
were considered poor as compared with other sub-sectors could be due to less attention paid from the
government. Our study suggests that Government of Pakistan should consider the importance of both
agricultural sub-sectors to increase there’s contribution growth rate towards agriculture GDP growth rate in
Pakistan.

Optimization Model of Use of Production in Order to Increase Production and E...AI Publications
This research aims to; analyze the optimization model of the use of production inputs in order to increase production and the efficiency of potato farming. This study uses cross-section data from 62 farmers. Sampling was done by Simple Random Sampling. The approach taken to examine the response of production to inputs is made descriptively. The production and efficiency functions are estimated using the stochastic frontier production function and the dual cost function. The results showed that there was no optimal use of production inputs. The frontier production function was mainly determined by the input of seed production of SP-36 fertilizer, KCL fertilizer, and liquid insecticide. The determinants of optimal production are determined by the use of seeds, urea fertilizer, and the use of drugs. The optimal use of inputs can produce an optimal production of 21,768 kg, while the actual production is only 12,250 kg. The use of seeds, SP-36 fertilizer, organic fertilizers, liquid insecticides, and labor are risk-reducing productivity factors. The technical efficiency of potato farming is in the medium category (ET=0.6644). Sources of technical inefficiency mainly come from the land area, age, and distance of farming land. Meanwhile, income, farming experience education and the number of family members reduce the occurrence of technical inefficiency. Farmers' behavior in responding to productivity risks is the average risk taker.
Spatial Analysis of Cropping Pattern in Malwa Region of the Indian Punjabijtsrd
The present paper spatially analysis the cropping pattern in Malwa region of the India Punjab by using secondary sources of data i.e. from 2000 2001 to 2010 2011. Districts has been selected as a spatial unit of the present study. The study yields some interesting findings is that the cropping pattern of the study area had drastically changed. It has been observed that the traditional crops of the region have shifted to modern paddy crops specially to rice and wheat during the one decade.

The research objectives achieved in this study were estimating the level of income
and feasibility of pulut uri organic farming in the District of Muting in Merauke
Regency. the type of research used is descriptive analytical research using basic data
from the results of previous studies, namely experimental research in organic
cultivation of uri corn. The basic data obtained is the data of organic uri corn on the
treatment of 0 tons / ha, 5 tons / ha, and 10 tons / ha of organic fertilizer. In this
study, identification of production, income and business feasibility costs will be
carried out using basic selling prices at the merchant level and at the end of the
consumer level. The data were analyzed by revenue, income / profit and feasibility
analysis of uri corn pulp. The results of the study concluded that with the selling price
of R. 3,000 / kg in the yield of pulverized corn, farmers would not get a large profit
with a feasibility rate of <1, which means that at that price level the farmers would
lose. Whereas with the selling price of Rp. 10,000 / kg of farmer's income will be
greater with the feasibility level> 1 which means that farmers will get profits or in
other words pulut organic corn farming can be developed in Merauke Regency
Analysis of technical Efficiency of traditional wheat farming in Fezzan regio...Premier Publishers
Although the efforts to enhance the productivity of wheat in Libya, it is still low and there is no improvement in wheat yield over the last decade indicating the usage of inputs in process of production is not efficient. Though some farms use modern methods in planting wheat, nevertheless a lot of wheat farmers are still using the traditional method of production. This paper aims to examine the technical efficiency of traditional wheat farming in Fezzan region, Libya as well as factors affecting technical inefficiency. A set of questionnaires was used to obtain data from 149 traditional wheat farmers selected by using a simple random sampling technique. The slack based data envelopment analysis model (SBM) was used to estimate technical efficiency and fractional regression model to determine factors response for inefficiency. Results showed that, the average technical efficiency of the farms was 0.69 indicating that farmers were operating at a low level of technical efficiency. This indicates that there is a need to improve technical efficiency by about 0.31 with the same level of inputs. The results of slack analysis revealed that the total inputs used by the traditional farmers would be reduced by 42 kg/ha for DAP, 58 kg/ha for seed, 14kg/ha for urea, 33 kg/ha for organic fertilizers and 12.9 man-days/ha for labour.

To alleviate the deficiency of green and dry fodder and to maximize the fodder production for increased a productivity of livestock was studied among 310 respondents of 23 non-delta districts of Tamil Nadu. The results showed that, gain among different types of faming, increased quantum of feeding and increased body weight gain and daily average milk yield among the indigenous as well as cross breed animals.
This document summarizes a study that estimates output supply and input demand elasticities for rice production in Sri Lanka using a restricted normalized translog profit function approach. The study analyzes four major rice producing districts from 1990-2012. The results show that changes in input and output prices significantly affect farmer profits, rice supply, and input use. Rice supply elasticity with respect to price is 0.5, while fertilizer demand elasticity with respect to price is -0.05 on average. Fertilizer subsidy increases both fertilizer demand and rice supply. Low substitution elasticity between labor and fertilizer indicates complementary relationships that synergistically increase production when applied together. Overall, higher output prices are essential for greater rice production according to

This document analyzes the technical efficiency of rice farmers in Ahero Irrigation Scheme, Kenya. It begins with background on rice production and consumption trends in Kenya. Rice consumption has been increasing at 12% annually compared to 4% for wheat and 1% for maize. However, production has not kept pace with demand, resulting in a large import deficit. The study estimates a stochastic Cobb-Douglas production function to determine technical efficiency and its determinants. It finds the technical efficiency of rice farmers is 0.82. Gender, farming experience, income level, and distance to market significantly influence technical efficiency. The study recommends policies to improve input affordability and farm incomes, as well as transport infrastructure, to increase efficiency of rice
Analysis of agricultural subsectors contribution growth rate in the agricultu...inventionjournals
In the current study, we have analyzed the contribution of agricultural sub-sectors growth rate to
the agriculture GDP growth rate of Pakistan by using secondary data from 2001 to 2015. Ordinary Least
Square (OLS) method was applied to estimate the model parameter. For this purpose the study considered a
dependent variable of agriculture GDP growth rate and several independents variables include major, minor
crops, livestock, fishery and forestry. The regression analysis of the data showed a positive and significant
contribution in agriculture GDP growth rate. However, fishery and forestry sub-sectors contribute growth rates
were considered poor as compared with other sub-sectors could be due to less attention paid from the
government. Our study suggests that Government of Pakistan should consider the importance of both
agricultural sub-sectors to increase there’s contribution growth rate towards agriculture GDP growth rate in
Pakistan.

Optimization Model of Use of Production in Order to Increase Production and E...AI Publications
This research aims to; analyze the optimization model of the use of production inputs in order to increase production and the efficiency of potato farming. This study uses cross-section data from 62 farmers. Sampling was done by Simple Random Sampling. The approach taken to examine the response of production to inputs is made descriptively. The production and efficiency functions are estimated using the stochastic frontier production function and the dual cost function. The results showed that there was no optimal use of production inputs. The frontier production function was mainly determined by the input of seed production of SP-36 fertilizer, KCL fertilizer, and liquid insecticide. The determinants of optimal production are determined by the use of seeds, urea fertilizer, and the use of drugs. The optimal use of inputs can produce an optimal production of 21,768 kg, while the actual production is only 12,250 kg. The use of seeds, SP-36 fertilizer, organic fertilizers, liquid insecticides, and labor are risk-reducing productivity factors. The technical efficiency of potato farming is in the medium category (ET=0.6644). Sources of technical inefficiency mainly come from the land area, age, and distance of farming land. Meanwhile, income, farming experience education and the number of family members reduce the occurrence of technical inefficiency. Farmers' behavior in responding to productivity risks is the average risk taker.

2) This led to around 6 million cubic meters of water passing through the area and devastating two hydropower projects.
3) The dams formed from landslides and avalanches despite there being no rain, highlighting the risk of glacial lake outburst floods in the region during winter.
Heterogeneity of Soil Nutrients: A Review of Methodology, Variability and Imp...Bilingual Publishing Group
Soil nutrient heterogeneity highly correlates to plant growth and development of environmental quality. In order to better understand nutrient cycling, heterogeneity of soil nutrients and their driving mechanism in different land use types were summarized from 1945 to 2016. By grouping keywords indexed in the titles of articles from the data base of Web of Science, two hundred and thirty one publications related to our topics were used for analysis. Soil sampling and statistical method were compared, and spatial dependence and the impact factors for soil organic matter (SOM), Nitrogen (N), Phosphorus (P) and Potassium (K). The results showed that soil nutrient heterogeneity was influenced by different factors at different scales. The spatial dependence of SOM, N and P were mainly at the moderate level (48.9-59.0%) and strong level (33.3-42.2%), while for K was at strong level (63.6-84.6%) and moderate level (15.4-36.4%). This was mainly influenced by topography, soil loss, weather condition, parent material, soil type, soil texture, land use, human activities, soil moisture, mineral element, soil structure, animal and plant. These impact factors were summarized separately, and the influence of factors at different spatiotemporal scales was discussed. At the end of the review, the ideas for further research were postulated.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDSSérgio Sacani
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptxshubhijain836
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

. The transient was identified in deep James Webb Space Telescope (JWST)/NIRCam imaging from the JWST Advanced Deep Extragalactic Survey (JADES) program. Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (

counterparts, and to confirm that standardized luminosities nevertheless remain constant with redshift.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

rice production should not be viewed in isolation but in
the framework of agricultural production systems through
ecological and integrated systems” [1]
. This statement
highlights rice not only as one of the most important food
crops world-wide but also an intricate part of socio-cultural
influencer of many people’s lives. Rice is grown in about
120 countries and China leads other countries in the world
with a production of 214 million tonnes followed by India
with 116 million tonnes and these two countries together
contribute over 50 percent of the world’s output in 2019.
Nine out of the top ten and 13 out of the top twenty rice-
producing countries are in Southeast-Asia [2]
.
Rice contributed more than 40 percent of the total food
grains production in India in 2019 and accounted for 21
percent of global rice production. West Bengal, Uttar
Pradesh, Punjab, Andhra Pradesh, Odisha and Telangana
are the leading rice producing States in India [3]
. Boosting
the yields of rice is very much critical for the well-being
of millions of rice producers and consumers in India, as
around 22 percent of the population still lie Below Poverty
Line (BPL) in 2018 [4]
. Further, the demand for rice is pro-
jected at 137.3 million tonnes by 2050 [5]
. To accomplish
these goals, the rice yields must be increased by around
42 percent i.e., from the present level of 2393 kg/ha
(in 2011-2012) to 3400 kg/ha.
Telangana State is emerging as the ‘Rice Bowl of
India’ because, in a short span of five years, the area un-
der rice cultivation has doubled from 0.91 million hec-
tares in 2014-2015 to 1.93 million hectares in the 2018-
2019. Recently, with the completion of Kaleshwaram
Lift Irrigation Scheme, the extent of rice cultivation in
Telangana has increased in just one year from 1.93 million
hectares in 2018-2019 to 2.88 million hectares in 2019-
2020 and accordingly, production shot up from 6.6 mil-
lion tonnes to 10.5 million tonnes during this reference
period 2022 [6]
. So, the adequate water resources and other
inputs like seed, fertilizers subsidy, free power etc., being
provided by the State Government enabled the farmers
to take up rice cultivation. However, the statistical data
available in the offices of Joint Director of Agriculture in
Telangana has revealed drastic variations in rice produc-
tivity and resources usage. These variations in resources
usage contributed to low productivity of rice (compared
to potential) and this may arise owing to lower Technical
Efficiency (TE). This is an indicator of presence of techni-
cal inefficiency in rice productivity across the districts in
Telangana. Considering the socio-economic importance
of rice farming in this state, there seems to be a research
need for investigating the extent of such inefficiencies. It,
therefore, calls for a scientific inquiry on TE of rice pro-
duction in Telangana, which would be of much relevance
for farmers, researchers, policymakers and other stake-
holders to take appropriate measures for enhancing TE in
rice productivity, efficient management practices and con-
sequent, sustainable agricultural planning. In this context,
this study formulated the following three research ques-
tions viz., what is the TE of rice productivity across all
the districts in Telangana? What is the trend in TEs of rice
productivity over a period of time? What input quantities
are required to produce at the technically efficient point on
the production frontier? [4]
So, this study gives an impor-
tant direction to farmers for employing right combination
of productive resources in the rice production programme.
Further, the lack of empirical studies in Telangana on this
pertinent issue has prompted the researcher to conduct sci-
entific enquiry across the 32 rice producing districts with
the following specific objectives:
● To estimate TEs in rice productivity across the dis-
tricts or Decision-Making Units (DMUs) in Telan-
gana
● To find out the potentials for reduction in the levels
of critical inputs across the DMUs.
● To analyze the trends in TE and sources of TFP of
rice over the study period.
2. Review of Literature
There have been a sizeable number of studies on ef-
ficiency measure in the field of agriculture through apply-
ing DEA approach because of its non-parametric nature.
A review of literature on application of DEA in measuring
efficiency in crop productivity is presented here under.
Tolga et al. (2009) [7]
measured TE and determinants of
TE of rice farms in Marmara region, Turkey. Their study
revealed that mean TE score of sample rice farms was 0.92
and ranged between 0.75 to 1.00 implying that they can
reduce the inputs usage by eight per cent without affecting
the level of output.
Fabio (2015) [8]
studied both technical and scale ef-
ficiency in the Italian citrus farming through employing
both DEA and Stochastic Frontier Analysis (SFA). The
findings revealed that though the estimated TE from SFA
is on par with the DEA, the scale efficiency realized from
SFA is found higher compared to DEA. Both the models
revealed that TE and scale efficiency were positively in-
fluenced by farm size, unlike number of plots of land and
location of farm in a less-favoured area.
Sivasankari et al. (2017) [9]
employed DEA to analyze
the TE of rice farms in Cauvery delta zone of Tamil Nadu.
The findings revealed that TE index ranged from 0.41
to 1.00 under both Constant Returns to Scale (CRS) and
0.48 to 1.00 under Variable Returns to Scale (VRS) speci-
fications with mean TEs of 0.76 and 0.81 respectively.
7. 3
Research on World Agricultural Economy | Volume 03 | Issue 03 | September 2022
Regarding scale efficiency, majority of the farms (81%)
exhibited showed Increasing Return to Scale (IRS). The
study also inferred that there is excess use for all inputs
especially for fertilizers like potash, phosphorus and farm
yard manure among the sample farms.
Bingjun and Xiaoxiao (2018) [10]
analyzed rice produc-
tion efficiency based on DEA-Malmquist Indices in Henan
Province of China. The results showed that from the time
dimension (2006-2016), the comprehensive TE change,
the technological progress change, the pure TE change,
the scale efficiency change and the TFP change have not
shown much improvement. However, from the perspec-
tive of spatial dimension, the TFP of rice in all provinces
is less than one, mainly because the production technol-
ogy was not fully utilized in each area. So, they suggested
strengthening of research and development, dissemination
of advanced production technology, proper allocation of
production factors etc., should deserve special attention to
ensure efficiency improvement and thereby, food security
of the country.
Joseph et al. (2018) [11]
employed DEA to measure TE
of rice production in the Centre region of Cameroon con-
sidering both CRS and VRS assumptions. The findings re-
vealed that the mean TE score is 0.67 and 0.95 at the CRS
and VRS respectively and with a mean scale efficiency of
0.70.
Shamsudeen et al. (2018) [4]
employed input-oriented
DEA to analyze the TE of rice production in northern
Ghana for the 2011-2012 cropping season. The mean
TE score was 77 percent implying the farmers employed
higher doses of inputs viz., chemical fertilizer, seed,
weedicides and hired labour than their prescribed opti-
mum. Around 84.4 of the sample farms experienced IRS,
while 5.6 per cent experienced Decreasing Returns to
Scale (DRS).
Nazir and Abdur (2022) [12]
analysed the TFP of cash
crops viz., sugarcane, cotton, and rice in Pakistan by em-
ploying Malmquist productivity index. The study decom-
posed the TFP of cash crops into technical change and TE
change. The findings showed an increase in the TFP of
selected cash crops in Pakistan by 2.2 percent and this is
mainly attributed to technical change. So, the researchers
emphasized on increasing both research and extension
investments to provide better seed varieties, better infra-
structure, and timely credit facilities.
3. Analytical Framework and Methodology
This study uses a two-step approach. In the first step,
the DEA model was employed to measure TE of DMUs as
an explicit function of discretionary variables pertaining to
Kharif season, 2021-2022. In the second step, DEA-based
Malmquist Index was used to analyze the trends in TE of
rice productivity during Kharif season across the DMUs
over the reference period, 2019-2020 to 2021-2022. This
study considered all the 32 DMUs in Telangana consider-
ing output variable (rice productivity) and input variables
(seed rate, fertilizer doses (NPK), water applied during
crop growth period and organic manure). The secondary
data on these variables are collected from respective Joint
Director of Agriculture Offices at DMU level.
3.1 DEA
This linear programming tool was employed to meas-
ure the TE of rice productivity in Telangana considering
input-oriented-CRS model [13-15]
. In this model, there are
32 DMUs and each DMU uses four inputs (K) and pro-
duces one output (M). For the ith
DMU, these are repre-
sented by the vectors xi and yi, respectively. The selected
inputs and output are represented by a K × N input matrix
denoted by X, and M × N output matrix denoted by Y
respectively. For the ith
DMU, the efficiency score θ is ob-
tained by solving the linear programming as follows:
minθλ θ
st
-yi + Yλ > 0
θxi - Xλ > 0
λ > 0
Here, θ indicates the TE score of input-oriented CRS of
the DMU under evaluation. If the value of θ = 1, it implies
the DMU is functioning on the production frontier with
100 per cent of efficiency and hence, there is no need for
changing the level of resources employed in the produc-
tion. On the contrary, if θ < 1, it implies the DMU under
consideration is relatively inefficient and thus, it could
reduce the level of inputs usage without affecting the out-
put [9]
.
3.2 Malmquist TFP Index: Input Oriented, CRS
This index based on DEA is employed to study the
trends in TE, technological change, Pure TE change, scale
efficiency change and changes in TFP of rice productiv-
ity during 2019-2020 to 2021-2022 across the selected 32
DMUs. So, the average values of the selected output and
input variables during this reference period are subjected
to DEA-based Malmquist Index analysis. The change in
productivity from the period t to t + 1 is calculated using
the following formula [9,16]

The first term on the RHS of the above equation in-
dicates the change in input-based TE between the years
t and t + 1, while the second term indicate the change in
technology between the selected periods. From the above
Equation (2), it can be inferred that the product of change
in TE and technological change gives a measure of change
in TFP. If the TFP is 1, it implies the TFP is increasing
during the selected periods (t and t + 1) and vice versa
and if the TFP = 1, it implies no change [15]
. To obtain the
change in Malmquist Indices, the following series of Lin-
ear Programing Problems (LPPs) are to be solved [16]

These LPPs are solved for each firm in the sample.
Therefore, given the number of periods (T) and number of
observations (N), [N × (3T - 2)] problems are to be solved.
This study considered all the 32 districts (as the DMUs)
in Telangana and the relevant secondary data are obtained
from respective Joint Director of Agriculture Offices. Rice
yield (kg/ha) is considered as the output, whereas seed
rate, fertilizer doses (NPK), annual rainfall received (mm)
and organic manure are considered as inputs. The aver-
age values of the output and input variables (2019-2020
to 2021-2022) are collected for the DMUs and subjected
to DEA and DEA-based Malmquist TFP Index analysis
for estimating the TE and change in TE respectively. The
efficiency analysis and Malmquist Index for efficiency
change over time has been done using the DEAP version
2.1 program developed by Coelli, 1996 [15]
.
3.3 Sample Adequacy Test
According to Cooper et al., 2007 [17]
, the thumb rules
for sample size acceptable for conducting DEA should be
either greater than or equal to the product of inputs (X)
and outputs (Y) or the sample size should be at least three
times the sum of the number of X and Y variables. So,
considering X = 4 and Y = 1, the sample size of 32 DMUs
in Telangana confirms the sample adequacy for conduct-
ing DEA.
4. Results and Discussion
4.1 Summary Statistics of Output and Input Vari-
ables
Table 1 shows that the average productivity of rice in Tel-
angana was estimated as 3288.28 kg/ha with maximum and
minimum productivity levels of 3705 kg/ha and 2720 kg/ha
respectively with the estimated Coefficient of Variation
(CV) of 59.928 percent. There exist larger variations
across the DMUs in terms of inputs usage viz., fertilizer
doses, seed rate, water applied and organic manure. Re-
garding the quantity of fertilizers (NPK) applied, it ranged
from 110 kg/ha to 350 kg/ha with an average value of
263.37 kg/ha and CV of 55.798 percent. The application
of chemical fertilizers is on the higher side among all the
DMUs compared to the recommended dosages (NPK
@ 120:40:40 kg ha-1
for short duration varieties; NPK
@ 150:50:60 kg ha-1
for medium duration varieties and
NPK @ 150:50:80 kg ha-1
for long duration varieties).
Similarly, average quantity of water applied was 1190.01
mm with minimum and maximum values of 780 mm and
1670 mm respectively and with a CV of 41.579 percent.
For majority of the DMUs (87%), the actual quantity of
water applied is higher than the scientific recommenda-
tion of 1200 mm to 1250 mm. The quantity of seed used
pitches between 17 kg/ha and 28 kg/ha with a mean value
of 23.47 kg/ha and with a CV of 38.508 percent. A close
examination of the data collected, the actual seed used
by all the DMUs is considerably higher compared to the
recommended level of 20 kg/ha. However, the CV is
9. 5
Research on World Agricultural Economy | Volume 03 | Issue 03 | September 2022
slightly lower with respect to organic manure applied for
rice cultivation (24.617%) and across the DMUs it varied
between 2 t/ha to 12 t/ha with an average of 8.37 t/ha.
The higher CVs of inputs is an indicative of presence of
technical inefficiency in contributing to the productivity
of rice across the DMUs in Telangana. Again for major-
ity of the DMUs, the quantity of organic manure applied
is higher compared to the recommended dosage of 8 t/ha
to 10 t/ha. Though the application of this input is on the
higher side, it is heartening that the farmers realized the
importance of organic farming in producing both cost-
effective and quality output.
4.2 DEA-Input-oriented CRS
The results of CRS TE scores (θ) along with bench-
marking DMUs and peer lambda weights (λj) for the
DMUs under evaluation are presented through Table 2.
The findings revealed that only nine out of 32 DMUs
namely, Karimnagar, Jogulamba Gadwal, Kamareddy,
Khammam, Mahabubnagar, Medak, Medchal-Malkajgiri,
Narayanpet and Suryapet received TE score of ‘1’. This
implies they are the best performing DMUs in Telangana,
as they are operating on the efficiency frontier in the peer
group. For the remaining 23 DMUs, the TE scores are less
than one ranging between 0.592 (Warangal-Rural) to 0.931
(Jagtial) with a mean TE score of 0.806. This implies pres-
ence of relative technical inefficiency in rice productivity,
as these 23 DMUs are operating below the efficiency fron-
tier. So, these 23 DMUs could reduce current level inputs
to the tune of 19.4 per cent without affecting the rice pro-
ductivity. The overall mean TE score for all the 32 DMUs
was estimated as 0.860 indicating relative technical inef-
ficiency is to the extent of 14 percent. This means that, on
an average, the DMUs can check over-use of current level
input resources to the tune of 14 percent without affecting
the rice productivity in the State. The DMU, Warangal-
Rural is with the lowest TE score of 0.592 followed by
Vikarabad (0.611), Mulugu (0.661), Mancherial (0.717)
etc., and all are lying at the bottom of the performance
ladder (Table 3). So, these DMUs could reduce the cur-
rent level of input usage by 40.80, 38.90, 33.90 and 28.30
percents respectively without affecting their correspond-
ing rice productivity levels. For the inefficient DMUs
(θ 1), the benchmarking DMUs are given in Column
4 and it will guide the former to reduce their inputs us-
age corresponding to the benchmarking DMUs [9,10]
. For
example, Suryapet and Kamareddy are the benchmarking
DMUs for Adilabad with respective lambda (λj) weights
of 0.903 and 0.023. With the λj weights, the benchmark-
ing DMUs form linear combinations with the inefficient
DMUs in terms of efficiency perspective. For the efficient
DMUs (with TE score of 1.000), the benchmarking DMUs
are peer of themselves with λj weights of ‘one’.
The comparative picture of efficient and inefficient
DMUs in terms of TE scores (Figure 1) indicate that the
dark color bars represent the DMUs (9) operating on the
efficiency frontier (with TE scores of ‘1’) and the light
color bars denote the DMUs (23) lying below the efficien-
cy frontier (with TE scores of ‘1’). So, the vertical gap
between efficient and inefficient DMUs indicate the extent
of technical inefficiencies of 23 DMUs.
4.3 Determining Optimal Level of Inputs Utiliza-
tion from the CRS Model
From Table 2, it was inferred that there are nine techni-
cally efficient DMUs and 23 technically inefficient DMUs.
Accordingly, DMU-wise projected input quantities and
possible reductions across inefficient DMUs was comput-
ed [14,15]
to realize higher TE scores without affecting their
current level of rice productivity (Table 4). The projected
input quantities indicate the minimum quantities of select-
ed inputs required across the DMUs to produce technical-
ly efficient output on the production frontier. So, the dif-
ference between actual and projected quantities of inputs
(obtained from the one-stage DEA) indicate the possible
input quantity reductions. For example, the actual use of
fertilizers, seed rate, water applied and organic manure
for the DMU, Adilabad are 205.935 kg/ha, 32.67 kg/ha,

1511.301 mm and 10.215 t/ha respectively, whereas the
projected input values obtained from the model for main-
taining the same productivity (3124.73 kg/ha) are 145.395
kg/ha, 27.04 kg/ha, 1276.821 mm and 6.455 t/ha respec-
tively. So, the estimated differences between the actual
and projected input values (fertilizers 60.54 kg/ha; seed
use 5.63 kg/ha; water applied 234.48 mm and organic
manure 3.76 t/ha) indicate their excess use in rice produc-
tion. Hence, this excess use of inputs should be reduced
for Adilabad without affecting rice productivity. The same
explanation can be offered for other technically inefficient
DMUs. However, for the efficient DMUs with TE score
1.000, the gap between actual and projected input usage is
around zero, as they are already operating on the produc-
tion frontier (the best performing DMUs) and hence, there
is no scope for reduction in the existing level of inputs
usage. At the pooled (State) level i.e., considering the
average of all the DMUs, there is overuse of fertilizers,
seed use, water applied and organic manure to the tune of
53.998 kg/ha, 6.528 kg/ha, 86.436 mm and 2.249 t/ha re-
spectively, as the production scenario of rice in dominated
by technically inefficient DMUs (23) compared to only
nine technical efficient DMUs.
So, it is felt appropriate to compare the extent of inputs
usage between technically efficient DMUs and technically
inefficient DMUs in terms of rice productivity in Telan-
gana. As shown through Table 5, the efficient DMUs (n =
9) employed on an average of 170.184 kg/ha of fertilizer,
21.667 kg/ha of seed, 1275.986 mm of water applied and
5.000 t/ha of organic manure to produce a yield of 3317 kg/ha
of rice. However, for the inefficient DMUs (n = 23), to
move up to the production level of the efficient DMUs,
they should check excess application of fertilizers by
40.105 kg/ha, seed by 3.724 kg/ha, water use by 36.100
mm and organic manure by 2.870 t/ha in order to boost
rice productivity by 778 kg/ha [4]
.
4.4 Trends in TE of DMUs - Malmquist TFP In-
dex
Table 6 portrayed the Malmquist indices for each DMU
during the period 2019-2020 to 2021-2022 [18]
. The find-
ings revealed that with reference to TE change index,
78 percent of the DMUs have made progress (TE change
value 1.000) and remaining 22 percent of DMUs have
regressed (TE change value 1.000). The top three DMUs
that showed progress with reference to TE change in-
clude: Nizamabad (48.3%), Nagarkurnool (45.5%) and
Sangareddy (43.4%) and the top three DMUs that are
regressed in terms of TE change are Kumuram Bheem
(30.3%), Jagtial (22.2%) and Khammam (19.5%). It is
heartening that the mean score for TE change in Telan-
gana is more than 1 (i.e. 1.153) and this shows that the
DMUs as a whole have witnessed impressive performance
in TE change of rice productivity during the reference pe-
riod [9,10,16]
.
However, it is disappointing that 56% of the DMUs
have regressed with reference to technological change
during the above reference period and hence, the mean
score of technological index in Telangana is less than one
(0.983). The top three DMUs that are regressed include:
Mulugu, Medak and Narayanpet with 13.6 percent, 12.9
percent and 12.8 percent respectively. It is found interest-
ing that majority of the DMUs have showed progress with
reference to pure TE change (53%) and scale efficiency
change (59%). Further, 75 percent of the DMUs showed
progress with reference to TFP change and remaining 25
percent of DMUs have regressed. The top three DMUs
viz., Nizamabad, Karimnagar and Sangareddy have
enjoyed TFP growth of 42.1 percent, 40.1 percent and
35.2 percent respectively. At the state level, the results are
found encouraging with reference to TE change (15.3%),
pure TE change (4.2%), Scale efficiency change (0.9%)
and TFP change (11.2%). So, on comparing the TE change
and technological change, it can be inferred that the pro-
gress in TFP change is purely from TE change during the
reference period.
The break-up of Malmquist indices across the selected
periods viz., 2019-2020 to 2021-2022 (Table 7) revealed
that TE change has showed increasing trend during from
1.139 (2019-2020) to 1.179 (2021-2022) with mean TE
change of 1.153. This shows that there is a gradual pro-
gress in terms of TE change for enhancing rice productiv-
ity in the State during the overall reference period. On the
contrary, the mean technological change was regressed
during the reference period with 0.983. Though techno-
logical change was marginally progressed (2.7%) during
2021-2022 compared to 2020-2021, the mean technologi-
cal change is regressed during the overall reference pe-
riod. It is also interesting that the DMUs have marginally
progressed in terms of pure TE change (4.2%) and Scale
Efficiency change (0.9%) during the reference period. The
TFP change has witnessed progress in the State with an
average value of 1.112. Considering these trends, it can be
inferred that at State level, pure TE change and scale ef-
ficiency change have almost remained stagnant and hence,
the gain in TFP of rice in Telangana is solely due to TE
change of inputs over time.

5. Summary and Conclusions
Input-oriented DEA Model with CRS was employed in
this study to analyze the TE in rice productivity in Telan-
gana. Out of 32 DMUs considered, only nine DMUs are
found technically efficient. The overall TE score for Tel-
angana is 0.860 implying that the DMUs, on an average,
could reduce their inputs usage by 14 per cent without af-
fecting their current level of rice productivity. Compared
to technically efficient DMUs, inefficient DMUs has to
check the use of inputs viz, fertilizer use by 40.105 kg/
ha, seed use by 3.724 kg/ha, water use by 36.100 mm and
organic manure use by 2.870 t/ha in order to boost yield
by 778 kg/ha and to reach on the production frontier.
Malmquist index analysis concluded that the progress in
TFP change during 2019-2020 to 2021-2022 was purely
due to TE change only. During this period, on an aver-
age, the technological change has regressed and pure TE
change and scale efficiency change have almost remained
stagnant.
6. Policy Recommendations
Policy suggestions from this study include: dissemina-
tion of modern production technologies to the farmers,
capacity building of farmers on Good Agricultural Prac-
tices, supply of quality inputs to farmers at affordable
prices etc., should deserve special attention. The poor and
marginalized farmers cultivating rice in the State must be
encouraged to join Farmer-Producer Organizations (FPOs)
for availing need-based assistance, participation in various
training programs and benefit from strengthened back-
ward linkages to enhance TE of inputs usage. Further, to
boost the technological change, the Government should
enhance investments both in research and extension. The
enabling environment in the State should be conducive to
promoting private sector agricultural investments [19]
. The
coordination between demand-driven research and tech-
nology dissemination should also be given priority.
Conflict of Interest
There is no conflict of interest.

. Pulses not only have nutritional value for human
beings but also contribute fertility to the soil. In spite of
huge nutritive value, per capita availability and consump-
tion is very low, which has been reduced almost half from
about 60.7 g/day in 1950-1951 to 48 g/day during 2018-
2019 [4]
.
The production of total pulses in India is about 23.40
million tonnes, covering an area of about 29.03 million
hectares (ha) during 2018-2019 [4]
, the majority of which
fall under rainfed, resource-poor and harsh environment,
frequently prone to drought and other abiotic stress condi-
tion. The 3rd
estimates for 2020-2021 indicate that the total
pulse production is 25.58 million tonnes from 29.51 mil-
lion ha area [5]
. To meet the demand of pulses, India is at
present importing about 3 million tonnes chickpea, which
continues to be the largest consumed and comprising of
45%-50% of the total pulse production of India. Major
producers of pulses in the country are Madhya Pradesh
(24%), Uttar Pradesh (16%), Maharashtra (14%), Ra-
jasthan (6%), Andhra Pradesh (10%), followed by Karna-
taka (7%), which together share about 77% of total pulses
production, while remaining 23% is contributed by Guja-
rat, Chhattisgarh, Bihar, Odisha and Jharkhand. India was
the world’s largest pulses importer and Myanmar, Canada
and Australia are major suppliers of dry peas and Kabuli
chickpeas to the Indian market.
Uttar Pradesh is the second-largest producer of pulses
with about 2.8 million tonnes, which accounts for 21.4%
of the national production. It continued to record the high-
est pulses productivity among the major pulses growing
states in the country. Pigeon pea, mung bean (green gram)
and urad bean (black gram) during kharif season and
chickpea, lentil and field pea, during rabi season are the
important crops with its share of 31.4% of the total area
under pulse in the state followed by lentil (21.5%), urad
bean/mung bean (16.5%), pigeon pea (14.1%) and field
pea (10.1%) [6]
. During the year 2018-2019, the area under
pulse was 2.30 million ha, production was 2.40 million
tonnes and productivity recorded at 1044 kg/ha [7]
.
Agro-climate zone wise information indicated that the
Bundelkhand zone shares maximum area under major
pulses (44.5%) followed by central plain zone (20.5%).
These two zones together share 65% area under pulses in
the state [8]
. The northeastern plain zones also share con-
siderable acreage under pigeon pea and lentil. Looking at
the productivity of individual pulse crop, it reveals that
in the case of urad bean and mung bean, the mid-western
plain and western plain zones have the highest produc-
tivity of 5.5 q/ha and 5.8 q/ha, respectively, however,
the Bundelkhand zone with considerable area possesses
lower average yield (1.3 q/ha and 2.6 q/ha). For pulse
crop against the state average of 5.3 q/ha and 5.5 q/ha in
the case of lentil, Bundelkhand zone possesses the high-
est acreage as well as productivity (10.1 q/ha) [6]
. Bun-
delkhand region is the central semi-arid plateau of India
that spans over about 7.1 million ha area. The region cov-
ers 14 districts comprising Jhansi, Jalaun, Lalitpur, Hamir-
pur, Mahoba, Banda and Chitrakoot of Uttar Pradesh and,
Newari, Datia, Tikamgarh, Chattarpur Damoh, Sagar and
Panna district in Madhya Pradesh state. The region is
complex, rainfed, risky, under invested, vulnerable, socio-
economical heterogeneous, ethically unique, agrarian and
backward [9,10]
. Among all the nine agro-climatic zones of
Uttar Pradesh state, Bundelkhand region of Uttar Pradesh
has the lowest average annual household income [11]
and
lowest livelihood security [12]
. Bundelkhand region suf-
fers from water scarcity, natural resource degradation, low
crop productivity (1 q/ha ~ 1.5 q/ha), low rainwater use
efficiency (35%–45%), high erosion, poor soil fertility,
frequent droughts, poor irrigation facilities, inadequate
vegetation cover and frequent crop failure resulting in
scarcity of food, fodder and fuel [13,14]
. The region experi-
ences extremes of temperature, varying from more than
45 °C during summers to about one degree centigrade in
winters and receives average 800 mm-900 mm annual
rainfall. The occurrence and distribution of rains however
have no definite pattern rendering farmers unprepared for
timely crop sowing and almost every year they faced the
problem of drought even during good rainfall year [15]
. A
declining and irregular trend of annual rainfall and a grad-
ual drying up of the region has emerged as a challenge to
sustain crop yield in the region [16]
. Droughts, short-term
rain and flooding in fields add to the uncertainties. Based
on the composite drought hazard analysis, eight districts
of Bundelkhand region are under severe to moderate
drought vulnerability [17]
. Bundelkhand region contrib-
utes 8.4% (1377 tonnes) of total pulse production in the
country. The contribution of the region to total area and
production of crops like field pea, lentil and urad bean is
highly significant as it contributes about 43%, 16% and
11.5% of total national production of field pea, urad bean
and lentil in the country. The overall productivity level of
pulses in the region (677 kg/ha) was slightly higher than
national average (655 kg/ha), the yield levels of field pea,
chickpea and lentil crops were also higher as compared to
the national average (2015-2016). Among the major pulse
crop growing in the Bundelkhand region are pigeon pea,
mung bean urad bean in kharif season and gram, pea,
lentil in rabi season. Gram is the most important pulse
crop in the Bundelkhand region followed by urad, lentil,
pea and mung bean.

Research on World Agricultural Economy | Volume 03 | Issue 03 | September 2022
Keeping in view the importance of pulse production in
the Bundelkhand region of Uttar Pradesh, this study has
been conducted to estimate pulse production status and
growth rates and make an objective assessment in terms
of cropping pattern, cost returns, market intermediaries
and marketed surplus as well as identify the constraints in
production and marketing of major pulses in the region.
2. Material and Methods
2.1 Area and Data
The study used both secondary and primary data to
achieve the objectives. Secondary data were collected
from published sources of Government Departments. For
collection of primary data, a multi-stage sampling tech-
nique was adopted to choose the study units, i.e. farmer
respondents. Bundelkhand region was selected purposive-
ly as cropping pattern in the region is dominated by pulse
crops. Bundelkhand region comprised of two-divisions,
viz. Jhansi and Chitrakoot Dham. At the first stage, one
district has been selected from each division, namely Ja-
laun from Jhansi division and Hamirpur from Chitrakoot
Dham division on the basis of higher area and production
of pulses. At second stage, one block from each district
has been selected randomly, in which Kadoura block from
Jalaun district and Kurara block from Hamirpur district
got selected. Third stage of sampling comprised of selec-
tion of 5 villages from each block and a total of 10 vil-
lages from the selected blocks were chosen randomly for
the study. From the universe of selected 10 villages, a list
of all those farmers i.e. pulses growers have been pre-
pared and thereafter a total of 100 respondent/pulse grow-
ers have been selected randomly. Again these respondents
have been categorized in four groups based on land hold-
ing size i.e. marginal (0 ha ~ 1 ha), small (1 ha ~ 2 ha),
medium (2 ha ~ 4 ha) and large (4 ha and above). Primary
data were collected from each respondent by personal
interview using a structured interview schedule regarding
farmer and farm details, cultivation practices, input used,
output marketed and returns received. The number of se-
lected cultivators from selected villages under each size
groups has been presented in Table 1.
2.2 Analytical Techniques
2.2.1 Estimation of Growth Rates
Data on area, production and yield collected for the
period of 1980 to 2015 were grouped into 3 periods, viz.
1980-1990, 1991-2000 and 2001-2015 and compound an-
nual growth rate (CAGR) was calculated separately for
each period.
2.2.2 Estimation of Costs and Returns
Costs of cultivation were also estimated using other
cost concepts [18]
that are widely adopted in farm manage-
ment research [19]
. The concepts used were: (i) Cost A= All
variable expenses incurred to procure the material inputs
and expenditure on hired labour, all types of machine la-
bour and including land revenue, depreciation and interest
on operational expenses, land (leased in) rent paid, (iii)
Cost B= Cost A + interest on value of permanent assets
and imputed rent of owned land, (v) Cost C= Cost B + im-
puted value of family labour. On the similar line, income

concepts used were as: (i) Gross return = Total value of the
produce (main product and by product), (ii) Net income =
Gross return - Cost C, (iii) Family labour income =
Gross return – Cost B, and (v) Farm business income =
Gross return – Cost A.
Cost C includes all the possible costs and is consid-
ered as the real cost of production in a farm situation.
But rental value of owned land and managerial costs for
the farmer can be excluded in a marginal profit situation
and Cost A can be taken as the standard cost of produc-
tion which includes all actual expenses expressed in cash
and kind, the depreciation and interest on value of owned
capital assets (excluding land) [19]
. Similarly, if we want to
calculate the income over family labour, we can consider
Cost B or subtract the value of family labour from Cost C.
2.2.3 Estimation of Marketable Surplus
Marketable surplus refers to the quantity of produce
available for disposal through markets after fulfilling all
consumption requirements. In this study, the marketable
surplus was estimated by subtracting requirements for
consumptions, seeds from the total production of pulses.
3. Result and Discussion
3.1 Production and Growth Rates
India is the largest producer of chickpea, sharing 65%
of global production [20]
. The production of pulses in India
during 2015-2016 is shown in Table 2. It is evident that
chickpea occupies a major share (46.68%) in total pulse
production in India followed by red gram, mung (green
gram), urad (black gram) and others.

Total pulses 17330 100
The estimated growth rates of red gram, chickpea, kha-
rif and rabi pulses with respect to area, production and
yield for the periods 1980-1990, 1991-2000 and 2001-
2015 are given in Table 3. The period-wise analysis re-
vealed that the maximum growth rate in the area for all
pulses, except chickpea was observed during 1980-1990
in comparison to other periods. The overall growth rate in
the area for all pulses was also highest (6.12%) during the
period 1980-1990 and there was a negative growth rate
for the next decade (1991-2000) and a positive growth
rate to the extent of 1.12% during the period 2001-2015.
Further crop-wise analysis of the growth rate in area of
kharif pulses was observed to be high in 1980-1990 and it
increased at the rate of nearly 8.08% per annum. Against
this, the area under the same crop during the period 1991-
2000 declined at a maximum rate of 8.26% per annum and
a negative growth rate was observed during 2001-2015
(–0.25% per annum). In the case of chickpea, growth rate

in area was observed to be high (17.42%) during 1991-
2000 and the growth rate declined to one-third (5.36%)
during 2001-2015, while the negative growth rate was
observed for the same crop during 1980-1990. The growth
rate in the area in case of red gram was observed to be the
same (2.3%) in the period 1980-1990 1991-2000 and it
declined at a rate of nearly 2.5% per annum during 2001-
2015. The growth rate in the production of different pulses
in different periods shows that maximum growth has been
exhibited by chickpea which was 10.01% per annum fol-
lowed by red gram (6.3%) during 1991-2000. During
the period 1980-1990, the growth rate of production of
all pulses was positive except chickpea. The growth rate
in production of total pulses was 3.4% during the period
2001-2015.
The Table 4 showed that the average size of farms,
which was 2.18 ha. The number of farmers in the marginal
size category (0 ha ~ 1 ha) accounted for 41% of the total
number of sample farms, commanding only 11.11% of the
total cultivated area, whereas, the farmers of the largest
size group (4 ha and above) accounted for only 14% of
the total number of holdings but commanded as much as
42.50% of the total cultivated area. This indicated the un-
even distribution of cultivated land among the farmers of
different size groups.
3.2 Cropping Pattern
In Uttar Pradesh, the Chitrakoot Dham region is fa-
mous for pulse production, where production takes place
under rainfed condition due to lack of irrigation facilities
and typical physiography. Chitrakoot Dham accounts for
18.11% of the total area and 25.67% of the total produc-
tion of the state. The productivity of pulses in this region
was higher in the state being 8.76 q/ha as against 8.08 q/ha
of the state average during 2012-2013. However, the pulse
production in the state as well as in the area did not show
any appreciable increase for the last fifty years, rather it
has been declined. The growth of pulse production in the
state was (–) 0.11% per annum, while it was 0.62% per
annum in Chitrakoot Dham and (+) 2.71% per annum in
Banda district.
Table 5 indicates that on an average, gram occupied
the highest area (20.70%) to the total cropped area fol-
lowed by wheat (20.18%), jowar + pigeonpea (16.92%),
lentil (12.15%), pea (10.14%), pigeon pea (9.93%), jowar
(6.99%), mung (4.88%), urad (4.19%), linseed and mus-
tard (6.30%) and others (4.50%). With regard to the size
groups for individual pulse crops, it is to be noted that
large farmers put higher proportion of cropped area to
gram, pea and urad, whereas for linseed-mustard, pigeon
pea and other crops, area decreased with increase in hold-
ing size. For the crops like lentil, wheat and jowar, no
such trend was observed.
Table 6 presented the production, costs and returns of
pulse crops from per unit area in the region. It is observed
that the cost of cultivation was highest for pigeon pea to
the extent of Rs. 20675 and the lowest was for lentil (Rs.
18161). However, due to higher yield level, per quintal
production expenses were lower in case of gram and pea
in comparison to pigeon pea and lentil. Due to higher sell-
ing price of pigeon pea, gross return was sufficiently high
than other pulses. On estimation of various categories
of costs, it was observed that though Cost C per ha was
highest for pigeon pea, Cost A B per ha was highest for
gram followed by pigeon pea, pea and lentil. With regard
to various types of income per ha, again pigeon pea re-
corded the highest income and highest benefit-cost ration
in comparison to other pulses.
From the above results, it can be concluded that pigeon
pea crop is the most economical and profitable pulse crop
having a higher benefit-cost ratio followed by gram than
that of lentil and pea crops and recommendation can be
made to put more emphasis toward their cultivation in the
study region.

3.3 Marketing Charges
The marketing charges paid by the village trader, wholesal-
er and retailer in the marketing of gram, pigeon pea, lentil and
pea were worked out at Rs. 40, Rs. 26 and Rs. 20 per quintals,
respectively. Total marketing charges paid by different
marketing middlemen were observed to be Rs. 86, spread
over the consumer’s price for the crops gram, pigeon pea,
lentil and pea has been shown in Table 7. The sale price
received by the producer was the highest being Rs. 3610
per quintal for pigeon pea, Rs. 2510 per quintal for lentil,
Rs. 2335 per quintal for gram and Rs. 2230 per quintal for
pea. The purchase price of consumers came to Rs. 2440,
Rs.3763, Rs.2629 and Rs. 2324 per quintal of gram, pi-
geon pea, lentil and pea, respectively. There were different
intermediaries, viz. village traders, wholesalers and retail-
ers who incurred market expenses to the extent of Rs. 40,
Rs. 26 and Rs. 20, respectively. Among the pulses, price
spread and market margins were highest in case of pigeon
pea followed by lentil, gram and pea. Producer’s share in
consumer’s rupee was calculated, which was almost simi-
lar for all the pulse crops indicating similar margin for the
farmers.

3.4 Marketable Surplus
In rural areas, family sizes remain almost similar, hence,
lower production owing from less cropped area led to low
quantum of marketable surplus of gram, pigeon pea, lentil and
pea and their percentage to the total production on the farms
of lower size group as compared to the large sized farms (Table
8). It is observed that the quantum of pulses consumed was
highest is gram, as it is a good source of energy, protein,
minerals, vitamins, fiber, and also contains potentially
health-beneficial phytochemicals [22]
. The quantity utilized
per household for all purposes comprising seed, consump-
tion, wages and others were also highest in case of gram
followed by pea, pigeon pea and lentil. The amount of
marketable surplus was highest in case of pea followed by
gram, lentil and pigeon pea. However, when we calculated
marketed surplus as percentage of quantity produced, again it
was observed to be highest for pea followed by lentil, pigeon
pea and gram.

4. Constraints in Cultivation of Pulses in
Bundelkhand Region
4.1 Constraints in Production
Non-availability of high yielding pulse varieties, in
general, have poor harvest index (HI). Improvement in the
HI in cereal crops in recent years has resulted in very high
yields. In pulses, the HI ranges from 10 to 20 as compared
to 40 and above in wheat. Mixed cropping of pulses with
other crops is an important agronomic practice in the
Bundelkhand area of the state. Here we could have two
24. 20
Research on World Agricultural Economy | Volume 03 | Issue 03 | September 2022
situations (i) the pulse crop completes its life-cycle before
the second crop enters the active growth phase, or (ii) the
pulse crop enters the active phase of growth only after the
subsidiary crop has completed its life-cycle. Although,
a number of improved varieties of different pulse crops
have been recommended, yet they have not become popu-
lar among the farmers in the study area mainly due to lack
of a systematic seed multiplication and distribution pro-
gram. Adequate plant population makes a big difference
in yield. Farmers in the study area generally do not follow
the recommended seed rate, which causes low yields.
4.2 Constraints in Marketing
During the course of the investigation, the following
market problems were ascertained in different regulated
mandis in the study area. When the farmer reached in the
market, they had to arrange with the kaccha arhatia (com-
mission agents) for the sale of produce. Kaccha arhatias
though employed by the producer, but they remained
more inclined towards the buyer and favored them at
the expense of producers. More number of intermediar-
ies in marketing channel reduces the producers’ share in
consumers’ price. There was common practice that after
settlement of price and during the time of weighing, the
buyer complained of the quality of product and levied
some refraction charges in spite of the price was settled on
the basis of a sample.
4.3 Constraints in Processing
The present-day processing technologies use direct
solar energy for drying in large open yards. In order to
loosen the husk, prolonged sun drying is essential for all
pulses, pigeon pea, black gram and green gram. The con-
version of grains into dal become difficult to mill mainly
during the summer months, whereas pulses that are easy
to dehusk are processed in other seasons. This limitation
restricts milling and production schedules. The cost and
time taken for processing of pulses in these units were
about 2-3 times higher when compared to the traditional
units. The time interval between each step and natural
splitting of grains produces good quality dal and improves
dal recovery and increases keeping quality of dal, which
fetches them a better price for their products.
5. Conclusions
It can be concluded that pigeon pea crop is the most
economical and profitable crop having a higher benefit-
cost ratio and contributing higher return than that of gram,
lentil and pea crops under study. In fact, pulses can be
profitably cultivated in rice fallows in the post rainy sea-
son, which also contributes in saving N fertilizer and in-
creased the yield of subsequent cereal crops, thus decline
the cost of production. Therefore, it is recommended that
more emphasis should be given towards the cultivation of
pigeon pea and gram than other pulse crops. Moreover,
it was observed that gross income, net income per ha and
the benefit-cost ratio was significantly higher on pigeon
pea as compared to gram, lentil and pea crops. Further,
lower or higher producer’s share cannot be considered as
a true indicator of an efficient marketing system. Efficient
marketing system is one in which both the producers and
consumers are well satisfied, benefited and protected from
the clutches of the marketing functionaries and middle-
men on the one hand and the consumers are in position to
get the product according to their preference and quality.
The government should take necessary steps in the regula-
tion of laws of regulated markets, control on the proces-
sor, wholesaler and retailer in the interest of both produc-
ers and consumers.

1. Introduction
Agriculture remains the main activity in the Ethiopian
economy. Agricultural growth is not only required to feed
the country but is also the driving force to generate for-
eign exchange. About 80% of Ethiopia’s foreign exchange
is derived from agricultural exports [1]
. Enhancing agricul-
tural production and export trade is the current strategy
followed by the country to curtail the critical capital short-
age and enhance economic growth.
Spices have a major stake in the production system
and the foreign earnings of the country. It has a great role
in transforming farmers into producers for the market in-
stead of producing merely for subsistence [2]
. Ethiopia has
become one of the largest consumers of spices in Africa.
People use spices to flavour bread, butter, meat, soups,
and vegetables. They also use spices to make medicines
and perfumes [3]
. Ethiopia is a homeland for many spices,
such as Ethiopian Korarima (Korarima/Aframomum Cor-
rorima), long red pepper, black cumin, white cumin/bish-
ops weed, coriander, fenugreek, turmeric, sage, cinnamon,
and ginger [3]
. Out of the 109 spices listed by International
Organization for Standardization (ISO), 50 spices are
cultivated or grown in Ethiopia. Apart from this, there are
several other spices and herbs available in small quantities [4]
.
The average land covered by spices is approximately
222,700 ha and the production is 244,000 tons per annum.
However, the supply has dwindled considerably in recent
years and the Ethiopian Korarima export was less than
100 MT in 2012. The production of Ethiopian Korarima
during the 2014/2015 crop season was 9.56 thousand tons
with a productivity of 5.1 Q/ha.
In Ethiopia, Southern National and Nationalities Peo-
ples Regional States (SNNP) is one of the regions which
produce the maximum quantity of spices in the country.
The major Ethiopian Korarima production areas are the
forest ecology of South and South West mid-altitude and
highland Korarima areas such as the Kaffa zone (center of
origin of Korarima), Bench-Maji zone, Sheka zone, Ma-
jang zone, Dawuro zone, Wolayita zone, and Gamo Gofa
zone, Kembata-Tembaro zone in SNNPR and Jimma zone
(Oromiya). The price of a kilo of dry Korarima capsule in
the domestic market ranges from 80 Birr to 100 Birr (One
US$ = 21 Birr) in the villages. Ethiopia exports about 200
MT of Ethiopian Korarima per year [4]
.
In South Omo Zone Korarima is also abundantly found
and potentially grown/produced by smallholder farmers
of South Ari, Semen Ari, and Salamago districts. In the
Zone, for the past five consecutive years about 16,843.96
ha, Korarima has grown with a production of around
70,744.63 Quintal with average productivity of 4.2 quin-
tal/ha [5]
. Korarima has a contribution to income genera-
tion and also has value in reducing/minimizing poverty
for smallholder farmers.
Despite, its availability, huge potential, and the role it
plays, limited attention has been given to its production,
value, value addition activities, and marketing outlets
choice. As result, the unregulated price of Korarima (black
market), South Omo zone Korarima is transported to Gofa
by the black market, and recognition and benefit from it
are given to the former Gamo Gofa zone. And also small
farm gate prices and less market access are disadvanta-
geous for producers. Therefore, this study focused on
identifying major value chain and marketing actors, value
additive activities in production, outlet choice in the mar-
keting of Korarima and its products, and identifying the
major value chain and marketing opportunities and con-
straints.
2. Research Methodology
2.1 Type and Sources of Data
Qualitative and quantitative data were collected from
primary and secondary data sources. The primary data on
the value chain and marketing of Korarima, value chain,
and marketing channels, direct and indirect benefits of
Korarima, supply and market price of Korarima, transac-
tion cost in marketing Korarima, main actors and their
role, margin share and distribution among market actors,
marketing infrastructure and information, market partici-
pants and concentration at each market chain, opportuni-
ties and threats of Korarima production and marketing,
farmers perception will be collected from key value chain
actors and stakeholders. Value chain actors and marketing
stakeholder includes sample producers, collectors, traders,
exporters, consumers, enterprise operators engaged in the
value chain and marketing of Korarima, end-users of the
products, formal and informal institutions involved in Ko-
rarima value chain and marketing, supporters of Korarima
value chain and marketing, as well as representatives from
government organizations and others working in Korarima
production. Secondary data were collected from literature,
reports, and documents both published and unpublished
data sources.
2.2 Methods of Data Collection
To collect the primary data both participatory rural ap-
praisal (PRA) tools of informal methods and formal sur-
vey methods of data collection were employed. Informal
survey methods such as focus group discussions (FGDs),
in-depth interviews with key informants (KII), and di-
rect observation with transacting walk will be employed,
28. 24
Research on World Agricultural Economy | Volume 03 | Issue 03 | September 2022
whereas for the formal survey method, structured survey
questionnaires were administered to sample respondents.
Informal survey such as focus group discussion with
known social strata groups (e.g. women, youths, elders,
others) was conducted before the formal survey. A ques-
tionnaire was pre-tested to indorse new information and
to modify the structured questionnaire. Open discussion
with producers, traders, consumers, and exporters were
interviewed according to their activities or function (as
Value Chain Analysis starts from production up to final
consumption).
2.3 Sampling Technique
Two-stage sampling technique was employed to draw
the sample from a given population of Korarima produc-
ers and traders. In the first stage, potential Korarima pro-
ducing and marketing Kebeles were identified purposive-
ly. In the second stage, sample households were identified
by random selection. Yemane [6]
sample size determination
formula was used to determine the number of respondents.

where, n=the sample size, N=total number of Korarima
producers, e=acceptable sampling error, and the value of
‘e’ is 95% confidence level and it’s assumed to be e=0.05.
After determination of sample size, the sample respondent
from smallholder household was selected randomly from
sample Kebeles.
2.4 Data Analysis
Both simple statistics and econometric models were
chosen for the analysis. The econometric analysis was
employed to analyze factors affecting the level of market
outlet choice and value addition. Software called Statisti-
cal Package for Social Science (SPSS) and STATA were
used for the analysis.
2.4.1 Econometric Model Specification
This study used a multivariate probit model as it cap-
tures the household variation in the choice of market
outlets and estimates several correlated binary outcomes
jointly. A multivariate probit model would be appropri-
ate for jointly predicting these three choices (collector,
retailer, and wholesaler) on an individual-specific basis.
A multivariate probit model simultaneously set out the
influence of a set of explanatory variables on the choice
of market outlets, while allowing for the potential correla-
tions between unobserved disturbances as well as the rela-
tionship between the choices of different market outlets [7]
.
In this case, three-outlet choices are collector, retailer,
and wholesaler and the model enables Korarima produc-
ers to choose more than one outlets that are not mutually
exclusive to get a better price. The selection of appropri-
ate market outlet i by farmer j is

The selection of one type of market outlet choice
would be dependent on the selection of the other, since
smallholder farmers’ choice decisions are interdependent,
suggesting the need to estimate them simultaneously. To
solve this problem many scholars suggested and used a
multivariate probit simulation model [8,9]
. Since smallhold-
er farmers’ market outlet choice decisions were expected
to be affected by the same set of explanatory variables.
Collectorj = x'1β1 + εA
Retailerj = x'2β2 + εB
Wℎolesalerj = x'3β3 + εC

where collector j, wholesaler j, and retailer j are binary
variables taking values 1 when farmer j selects collector,
wholesaler, and retailer respectively, and 0 otherwise; X1
to X4 is a vector of variables; β1 to β3 a vector of param-
eters to be estimated and ε disturbance term.
In a multivariate model, the use of several market out-
lets simultaneously is possible and the error terms jointly
follow a multivariate normal distribution (MVN) with
zero conditional mean and variance normalized to unity,

variables, given by

3. Results and Discussion
3.1 Socio-Economic and Demographic Charac-
teristics of the Respondents
This sub-section explains the profile of sampled re-
spondents regarding their age, sex, family size, experi-
ence, level of education, access to extension services, ac-
cess to market information, and distance from the nearest
market (Table 2). Gender was analyzed by checking the
number of male and female-headed households. Out of
the total households interviewed 95.8% were male-headed
households while 4.2% were female-headed households.
In both theoretical and practical situations, education level
plays an important role in ensuring household access to
basic needs such as food, shelter, and clothing. Skills and
education enhance working efficiency resulting in more
income and food security. In the study area, the mean
grade level achieved by respondents was about grade 6.
The minimum grade was 0 for those who were illiterate
and the maximum was grade (10+3). The age of sample
respondents was measured in years and provided a clue
on the working ages of households. The mean age of the
sample household was 37 years with the minimum and
maximum age of 18 and 65 years, respectively.
The mean family size of the total sample households
was nearly 7 persons with a minimum of 2 and a maxi-
mum of 12 persons and a standard deviation of 2.67.
Therefore, this might help them for a better market outlet
choice of households during Korarima marketing because
of labor availability. The respondents have an average of
17 years of farming experience in Korarima production
and marketing with a standard deviation of 11 years. The
total land size of sampled farmers varies from 0.13 to 3
hectares and the average farm size for sampled farmers is
found to be 0.78 hectares with a standard deviation of 0.53.
From the total land size, the land allotted to Korarima was
on average 0.29 ha with a minimum of 0.03 and a maxi-
mum of 1.5 ha with a standard deviation of 0.24.
According to the sample respondents, the major sourc-
es of income were crop, livestock, and livestock product
selling, and also there is some practice of getting off-farm
and non-farm sources. The total estimated average annual
income that the respondents obtained from those sources
was 12,192 Birr. Distance to market is an important vari-
able that affects the marketing of Korarima. The mean
distance to the market center for sample households was
18 minutes with a minimum of 10 and a maximum of 50
minutes of walking on their barefoot and a standard de-
viation of 2.67. Farmers who are located distant from the
market center might be weakly accessible to the market
outlet and have less transportation cost and time spent.
3.2 Korarima (Aframomum Corrorima) Cultiva-
tion Practice in the Study Area
Korarima is a known cash crop in the South Omo zone
and cultivation of it is mainly practiced in the agro for-
estry and river banks of South and Semen Ari areas of the
zone. According to Getasetegn and Tefera [10]
, the cultiva-
