Field experiment involving five improved onion (Allium cepa L.) varieties and carried out at Kulumsa Agricultural Research Center during the 2018 to 2019 cropping seasons under irrigated condition to identify the best performing variety for seed production to the target areas of Arsi Zone. The onion varieties included in the field experiment were (Nafis, Robaf, Nasic Red, Bombe Red, and Adama Red). The experimental design was a randomized complete block design (RCBD) with three replications. Phenological and growth parameters, seed yield, and yield components were studied. The result showed that Variety had a significant effect on most phonological and growth attributes as well as on yield attributes. The number of days to flowering and vigorously were significantly affected by variety; while plant height, days to boolting and branch number was not significantly influenced by variety. Flower stalks height and diameter, number of umbel per plant, and umbel diameter also significantly affected by variety. Seed yield per umbel and mean seed yield per hectare also showed a significance difference among varieties. The highest seed yield per hectare (1415.89 kg/ha) was recorded from Adama Red and followed by Nafis variety, whereas Nasic rerd, Bombe red and Robaf show no significance difference among each other, Therefore, it can be concluded that use of the improved onion varieties such as Adama red and Nafis is advisable and could be appropriate for onion seed production in the test area even though further testing is required to put the recommendation on a strong basis.
Evaluation of Hot Pepper Varieties (Capsicum species) for yield related trait...Premier Publishers
Hot pepper is one of the major vegetables and spice crop produced in west Gojjam in Burie District that serve as the source of income particularly for small holders in many parts of the study area. The study was conducted at two locations Alefa and Zalima kebeles. The aim of study was to evaluate the effect of growing environment on the performance of hot pepper varieties and the interaction effect of location with varieties on yield and yield related characters. The treatment Randomized Complete Block Design with three replications. The result of the study revealed that almost all of the parameters considered were significantly affected by the varieties but not significantly affected by the treatments. Therefore, farmers in the study area recommended to use some varieties accordingly Mareko Fana, Bako Local and Melka Eshet (with 6.34, 5.43 and 4.69 t/ha, respectively) could be used for better yield than the rest of hot pepper varieties evaluated during the study period.
Vegetables constitute an integral component of the cropping pattern but the increasing pressure on food and cash crops has limited the area under vegetables to about 0.62 million ha, which is 3.1% of the total cropped area. Vegetables fit well in most farming systems due to shorter maturity period.
Vegetable crops are very important due to their higher yield potential, higher return and high nutritional value and suitability for small land holding farmers. Vegetables provide proteins, minerals and vitamins required for human nutrition. In Pakistan, the daily per capita intake is low, being about 100 grams compared to the recommended consumption of about 285 grams. In view of population increase, land degradation and water scarcity, there is a need to substantially increase vegetable production in the years to come and to attain self-sufficiency as well as to increase the exportable surplus. However, in the past, development efforts in agriculture sector were primarily focused on production and development of cereal crops; in spite of the fact the vegetables provide maximum output per unit area.

Multilayer Cropping : Ideal approach for better yield and increasing farm incomeAntaraPramanik
In India mostly farmers (about 85%)comes under small and marginal farmers. In near future, availability of land for cultivation will be reduce with increasing population and rapid urbanization, degradation of land due to soil erosion and soil salinity.
As per estimate, in India more than 95% holding will be under the category of small and marginal holders by 2050 (Agrawal R.L., 1995) .
For solution of this problem, multi storied cropping system will be a potential and efficient option to provide food, nutritional and income security to the growing population of India (Awasthi O.P. et.al., 2008) . This has possible because of the diverse agro climatic condition, enormous biodiversity, wide variation in soil fertility, large cultivable land area in the geographical boundary of India. Multi-layer Cropping is a system of growing crops together of different heights at the same time on the same piece of land. It is also referred as multi-storied cropping or multi-tier cropping. Multilayer Cropping is based on the principle of high-density planting and making the ultimate and efficient use of manure, water, land, labour and vertical space.
This system of cropping also works on the principles of minimization of production cost and inputs use, development of organic and sustainable farming system in order to mitigate the use of chemicals and ensuring the food and nutritional security to each household.
Multilayer system of cropping is sustainable method of cropping that is cost effective and requires less labour . Therefore, people should be made aware of this type of farming system.
We know that many farmers in different countries are unwillingly killing themselves because they work hard in their land but they don’t get good production.
Farmers who are willing to do work are deprived of different resources like irrigation and good area of agricultural land. In this scenario, they can be motivated to do multi-layer system of cropping which can ultimately solves all these problem.
This system of cropping can helps to uplift the economic condition of farmer. The Multilayer Cropping System is indeed a boon to small & marginal farmers.

Genetic and Morphological Diversity Analysis of Ethiopian Mustard (Brasica ca...Premier Publishers
Growing of Ethiopian mustard, as an oilseed and leaf vegetable require genetic improvement which relies on its genetic diversity. The experiment was executed to analyse genetic and morphological diversity of Ethiopian mustard land races at Holetta agricultural research center. Forty-nine genotypes collected from different agro ecologies were analyzed using morphological traits in order to assess the genetic and morphological diversity that exists in these materials. The experiment was carried out in a simple lattice design. The analysis of variance showed that there were significant differences among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40, 50 and 60 days of growth and number of intact leaves at flowering. The significant difference indicates the existence of genetic variability among the accessions that is important for selection and breeding. For yield component traits, high genotypic and phenotypic coefficient of variations was observed in seed yield per plot and oil yield. This shows that selection of these traits based on phenotype, may be useful for yield improvement. The highest heritability in broad sense was recorded for thousand seed weight(68.80%), followed by days to flowering (65.91%), stand percent (63.14%), linolenic acid (62.58%), days to maturity(60.43%), plant height (59.63%), palmitic (58.19%), linoleic (57.46%),leaf area (52..09%), oil content (50.33%), leaf width (48.29%),leaf length(46.28%), oil yield(44.84%), fresh leaf biomass at 50 days of topping(43.40%), seed yield per plot(42.99%), number of leaves at vegetative state(40.48%), seed yield of 50 days growth stage topped plants(38.85%) and primary branches (34.20%). This suggests that large proportion of the total variance was due to high genotypic variance. Hence, a good progress can be made if some of these traits are considered as selection criteria for the improvement of yield, yield component and vegetative traits. The present study revealed the presence of considerable variability among genotypes for all traits compared except seed yield per plant, fresh leaf biomass per plant topped at 40,50 and 60 days of growth and number of intact leaves at flowering. These conditions indicate that there is good opportunity to improve these characters using the tested genotypes.
Effect of Seedling Density on Growth Attributes of Cauliflower variety Kathma...AI Publications
Nursery management including optimum seedling density is an important factor for better crop performance. A study was carried out to examine the effect of seedling density on growth attributes of cauliflower seedlings cv. Kathmandu local in the field of Lamjung Campus in Oct., 2018. Experiment consists of four treatments which were replicated five times and laid out in RCBD. Seed spacing treatments viz. 0.5cm x 1.0cm, 1.0cm x 1.0cm, 1.5cm x 1.5cm and 2.0cm x 2.0cm were maintained in a raised nursery beds. Field germination percentage was recorded up to 60% at fourth day after sowing (DAS) whereas in lab it was up to 74%. Above and below ground seedling biomass, unfold leaves area, number of true leaves, plant height and root length were recorded at 23 DAS by destructive method. ImageJ package was used for leaf area measurement. Data were tabulated in MS Excel and analyzed by GenStat. Root length (4.85cm) was significantly higher in spacing of 2cm x 2cm which was at par with 1.5cm x 1.5cm whereas lower in 0.5cm x 1.0cm. Significantly maximum value for fresh weight of root (0.045gm), fresh weight of shoot (0.91gm), dry weight of shoot (0.11gm) and dry matter percentage (12%) was observed in 1.5cm x 1.5cm spacing. Seedlings greater than 1.5cm to 2cm spacing performed better than closer spacing in most of the variable of interests, however, there was no significant differences observed in number of true leaves, leaf area and plant height. A trial with wider spacing considering seedling health is recommended.
Abstract— There is a strong desire amongst people to have colour in the shady areas of their landscapes. But shade-loving plants generally are not richly or brightly coloured. Ornamental coleus is an inconspicuous flower bearing ornamental plants which can act as a colorful option for shady landscape. Ornamental coleus is a promising ornamental foliage plant which provides a bold texture and a thick density for shady landscape. With this background, collection, conservation and evaluation of different ornamental coleus types / varieties carried out at ICAR-Central Coastal Agricultural Research Institute, Goa. Twenty four different types / varieties of ornamental coleus have been collected, maintained and evaluated for their suitability for landscape use. Significant differences were observed among different coleus types / varieties for various morphological and quality parameters. Plant height , number of leaves, number of branches, Stem girth, Length of leaf with petiole, Petiole length, leaf width, Length of leaf without petiole varied from 42.00 cm (Juicy Lucy) -89.67 cm (Eruption), 24.89 (Gay Delight) -72.00 (Trailing Queen), 3.00 (Mahogany Giant) -8.67 (Eruption), 0.563 cm (Blusher) - 0.817 cm (Eruption), 11.03 cm (Tilt a Whirl) - 18.83cm (Grape expectations), 2.07 cm (Pistachio Nightmare) - 6.00 cm (Eruption), 5.50 cm(Trailing Queen)-10.83 cm(Grape expectations), 8.33cm(Tilt a Whirl) - 14.78 cm (Grape expectations) respectively. Different ornamental coleus used in the present study exhibited an incredible range of diversity for various traits and it could be recommended to function for various purposes in landscaping like beds, borders, hedges, planters, hanging baskets, vertical gardens or containers.
Effect of nitrogen fertilizer rates and intra-row spacing on yield and yield ...Premier Publishers
A field experiment was conducted at Gode Polytechnic College demonstration farm in 2013 under irrigation to observe the effect of six N rates (0, 46, 69, 92, 115 and 138 kg ha-1) and four intra-row spacing levels (7.5, 10 12.5 and 15 cm) on yield and yield components of onion (Allium cepa L.). The experiment was laid out according to randomized complete block design in factorial arrangement with three replications. Results of the analysis revealed that the interaction effects of N rates and intra-row spacing showed highly significant (P<0.01) effect on harvest index, fresh biomass yield, dry biomass yield, total bulb yield and marketable bulb yield. Thus, according to the result of partial Budget analysis application of 138kg N ha-1 planted at 7.5cm plant to plant distance was found the best treatment than others in relation to yield and yield components of onion under Gode condition.

Groundnut is an important oil seed crop, grown throughout the tropics and sub tropics worldwide. It is one of the three economically important oilseed crops grown in Ethiopia. Groundnut is commonly produced by small scale farmers as food and cash crops in the study area. The area has potential to the production of Ground nut for food and nutrition security as well as export commodity. However, scarcity of varieties that fit to the environment is one of the major constraints of production. Therefore, this experiment was conducted to evaluate five Ground nut varieties and select early maturing varieties with considerable yield and agronomic traits. The field experiment was conducted in 2017 and 2018 at Abaya and varieties were planted in Randomized complete block design (RCBD). Data were collected on yield and important agronomic traits. The computed analysis of variance revealed significant variations among varieties for days to maturity, number of primary branches, number of pegs per plants, Grain yield and shelling percentage. The pooled over year mean of varieties indicated , Tole- 1 variety ( Check) is high yielding with mean grain yield of 4174.7kg followed by variety Sedi (3552.5kg/ha) and Babile local (3550.4kg/ha).Variety Sedi has special merit in terms of earliness and therefore recommended for moisture stress areas of Abaya and location with similar agro ecologies while Tole -1 (Standard check) is high yielding varieties and should be used in production until new varieties will be developed through selection/breeding program.
A field experiment was conducted to study the effects of plant spacing and phosphorus rates on yield related traits and yield of faba bean (Viacia faba L.) at Farmers Training Center, Duna District during 2015 summer cropping season. Three intra-rows spacing (5, 10 and 15 cm), three inter-rows spacing (30, 40 and 50 cm) and three phosphorus rates (0, 46 and 92 kg/ha) were tested. The experiment was laid out as a randomized complete block design (RCBD) and was replicated three times. Improved faba bean variety (Degaga) was ued as test crop. Phenological growth parameters yield and yield related data were collected and their ANOVA was analyzed using GenSta 5th edition and while treatment means were significantly different, they were separated using Least Significant Difference (LSD) at 5% probability level. There was highly significant (P<0.01) effect of the highest rate of phosphorus (92 kg P2O5 ha-1) on days to flowering, days to maturity, leaf area index, effective nodules per plant, plant height , primary tillers plant-1, seeds pod-1, hundred seed weight, grain yield, above ground dry biomass and harvest index. Significantly lowest days to flowering (54.3 days) after emergence and highest plant height (105.63 cm), leaf area (1073 cm2), seeds pod-1(3.57), grain yield (2633 kg ha-1), dry biomass (8108kg ha-1) and harvest index (32.47) were obtained from the highest rate of P (92 kg P2O5 ha-1). For all inter-rows spacing, the leaf area, number of primary tillers, pods plant-1, seeds pod-1 and hundred seed weight were increased as intra-row spacing increase and the highest leaf area (1084 cm2), primary tillers (2.99) and hundred seed weight (54.59 g) were obtained from the widest (50 cm) inter-row spacing, while the highest effective nodules (59.56) and leaf area index (3.51) were resulted from the narrowest (30 cm) inter-row spacing. On the other hand, the interaction effects of inter and intra-row spacing significantly influenced, number of pods plant-1, number of seeds pod-1, above ground dry biomass, grain yield and harvest index. The 30 cm inter-row by 15 cm intra-row spacing gave the highest grain yield (2495 kg ha-1), harvest index (35.79%) and pods plant-1(19.68) whereas the highest dry biomass (8738 kg ha-1) was obtained from 30 cm x 5 cm spacing combination. Thus, it can be concluded that application of 92 kg P2O5 ha-1 rate of phosphorus at 30 x 15 cm spacing combination proved to be superior with respect to grain yield in the study area. However, further study at least for one more cropping season under different soils is required to reach at conclusive recommendation.

Generally, the magnitudes of genotypic correlation coefficients for most of the characters were higher than their corresponding phenotypic correlation coefficients that indicate the presence of inherent association among various characters. In this study yield was positively correlated with hundred seed weight, number of seed/pod and number of pod per plant so, increasing these traits ultimately increases in grain yield and days to maturity can be exploited through improvement and selection program. Based on findings it can be concluded that pod length, number of pod /plant, biological yield, grain yield and days to maturity can be exploited through selection and improvement program to develop high yielding soybean genotypes.
Effect of Transplanting Age on the Growth and Yield of Green Pepper (Capsicum...BRNSS Publication Hub
A field experiment was conducted at the research farm of the Department of Crop Production and
Landscape Mangement of the Faculty of Agriculture, Ebonyi State University, Abakiliki, in Southeasthern
Agro-ecological zone of Nigeria for a period of 8 weeks to study the effect of transplanting age on
growth and yield of green pepper, laid out in a randomized complete block design in four replicates.
The agronomical characteristics that were measured were as follows: Plant height, number of leaves per
plants, days to 50% flowering, number of fruit per plot, and weight of fruit per plot (kg/plot). The result
of the field trial showed that transplanting age had a significant effect only on plant height at 8 weeks
of age of transplanting. The other vegetative parameters such as number of branches, number of leaves,
and 50% flowering and field component such as number and weight of fruits were not affected by the
transplanting age. Therefore, the best age to transplant green pepper is from 1 to 7 weeks, for optimum
performance.
A field experiment was conducted on at M.lekhe district (Ethiopia) during 2002 and 2003 years to investigate the response of tomato to rates of Nitrogen (N) and Phosphorus (P) fertilizers. The treatment consisted of factorial combination of four Nitrogen fertilizers rates (50 kg, 100 and 150 urea/ha) and four P rates (100,150 and 200 DAP/ha) arranged in a Randomized Complete Block Design. Statistically significant and highest yield per plant was recorded at the highest rate of DAP (200 kg/ha). The significantly lowest yield was found at the zero level (with out DAP applied). The marketable yield in Q/ha of the rates is 939.96, 822.44, 731.1067 and 421.44 for 200, 150, 100 and 0 rates respectively. As the partiual budget analisis showed increasing rate of phosphorus and urea fertilizers increased profitability until 200 kg/ha and 150 kg/ha respectively.
Performance of Sesame (Sesamum indicum L.) Under Different Supplementary Irri...CrimsonpublishersMCDA
Field experiment was conducted in Humera in 2015 main cropping season in a factorial randomized complete block design (RCBD) to study the performance of sesame under different supplementary irrigation applications and nitrogen fertilizer rates. The study consists of four levels of nitrogen fertilizer rates (0kg N2/ha, 23kgN2/ha, 37.5kgN2/ha and 46kgN2/ha) and three levels of supplementary irrigation; rain-fed (I0), four irrigations (I4), and six irrigations (I6). Nitrogen fertilizer was applied in two splits, with the first half at sowing and the remaining half 30 days after emergence. Data on plant height, number of capsules per plant, number of seeds per capsule, thousand seed weight, harvest index, aboveground biomass and grain yield were recorded. The analysis of variance (ANOVA), in indicated that application of nitrogen fertilizer significantly (p<0.05) affected sesame grain yield. The highest grain yield 423.4kg/ ha, and 455kg/ha was obtained from application of 46kg nitrogen per hectare, and six supplementary irrigation. The results obtained in this experiment showed that, application of supplementary irrigation could be an important climate change adaptation strategy in areas where onset and cessation of rainfall occur.
Genetic variability studies provide basic information for breeders to develop different stress-tolerant varieties. In the present study, forty-nine Tef genotypes were evaluated under strong acid soil (pH 4.97) and lime treated (pH 5.90) soils in the lathouse at Assosa Agricultural Research Center in 2017 to estimate the genetic variability, heritability and genetic advance of various traits of tef genotypes in relation to soil acidity stress. The result indicated that there was high significant (p<0.01) differences among genotypes for all traits under both environments; except for shoot biomass in the combined data analysis. The two environments differed significantly in their effect on all traits except on plant height, panicle length, culm length, total and fertile tillers and number of primary branches, although environment contribution to total TSS was less than 10% in 13 of the 17 traits studied; its high contribution was to harvest index (42.6%) and grain yield pot-1 (32.5%). Big reduction due to soil acidity was recorded for yield of primary panicle (27.78%), grain yield pot-1 (33.85%) and harvest index (35.6%). A contribution of G was from 44.5% in harvest index to 90.5% in panicle length. The GxE interaction was also significant for all traits and it contributed more than 15% in 11 of the traits, indicating inconsistency of performance of genotypes under acidic and lime treated soils. PCV, GCV, and GAM were high (>20%) for fertile tillers per plant, panicle weight, yield of primary panicle, grain yield, and harvest index under both acidity levels and in the combined analysis. Heritability was high (>60%) for all traits except for shoot biomass in the combined analysis and lime treated soil. In general, there was wide genetic variability in the traits studied pointing to the possibility of improving the desired traits, including grain yield under both environments and over environments through the selection of elite genotypes.
Growth, Yield and Economic Advantage of Onion (Allium cepa L.) Varieties in R...AI Publications
Haphazard and low soil fertility, low yielding verities and poor agronomic practices are among the major factors constraining onion production in the central rift valley of Ethiopia. Therefore, a field experiment was conducted in East Showa Zone of Adami Tulu Jido Combolcha district in central rift valley areas at ziway from October 2021 to April 2022 to identify appropriate rate of NPSB fertilizer and planting pattern of onion varieties. The experiment was laid out in split plot design of factorial arrangement in three replications. The main effect of NPSB blended fertilizer rates and varieties (red coach and red king) significantly (p<0.01) influenced plant height, leaf length, leaf diameter, leaf number and fresh leaf weight, shoot dry matter per plant, and harvest index. Total dry biomass, bulb diameter, neck diameter, average fresh bulb weight, bulb dry matter, marketable bulb yield, and total bulb yield were significantly (p<0.01) influenced only by the main effect of NPSB blended fertilizer rates. In addition, unmarketable bulb yield was statistically significantly affected (p≥0.05) by the blended fertilizer rates and planting pattern. Moreover, days to 90% maturity of onion was affected by the main factor of NPSB fertilizer rate, variety and planting pattern. The non-fertilized plants in the control treatment were inferior in all parameters except unmarketable bulb yield and harvest index. Significantly higher marketable bulb yield (41 t ha-1) and total bulb yield (41.33 t ha-1) was recorded from 300 kg ha-1 NPSB blended fertilizer rate applied. Double row planting method and hybrid red coach onion variety had also gave higher growth and yields. The study revealed that the highest net benefit of Birr, 878,894 with lest cost of Birr 148,006 by the combinations of 150 kg blended NPSB ha-1 with double row planting method (40cm*20cm*7cm) and red coach variety which can be recommendable for higher marketable bulb yield and economic return of hybrid onion for small scale farmers in the study area. Also, for resource full producers (investors), highest net benefit of Birr 1,205,372 with higher cost (159,628 Birr) by application of 300 kg NPSB ha-1 is recommended as a second option. However, the research should be replicated both in season and areas to more verify the recommendations.
Genetic characterization of morphological and yield traits in ten genotypes of Celosia argentea L. was evaluated
at the Research Farm of the Department of Botany, University of Ibadan, Nigeria. The experiment was laid out
in a randomized complete block design with four replicates. The results of analysis of variance carried out on
early morphological characters of C. argentea L. at 3, 4, and 5weeks after sowing showed significant
(p<0.05 /><0.01) effects except for number of leaves per plant and leaf width at 3 and 5 weeks after sowing,
respectively. The replicates in blocks produced varying observable effects on the genotypes while genotype x
replicate showed significant variation on morpho-agronomic and yield traits except number of days to flowering
at 50 days and fruit length at maturity. Also, from the result of the mean separation, it is shown that
NG/MAY/09/015 performed the best for plant height at flowering, leaf length at flowering, leaf width at
flowering, and root biomass. NG/SA/07/213 produced the highest mean values of number of flowers per plant,
leaf biomass and pod weight at maturity. The highest values of number of primary branches and fruit length at
maturity (FLM) were observed for NG/TO/MAY/09/015, while NG/AO/MAY/09/015 had the highest for pod
weight at maturity. The result of principal component axis also showed that Prin 1 accounted for highest Eigen
Vector of 38.62% from the total variation. NG/MAY/09/015 (R2) genotype produced the highest Eigen Vector
of 6.705 from Prin 1. The correlation result showed that plant height had a significant positive association with
seed weight at maturity, pod weight at maturity, number of primary branches and fruit length at maturity, while
similar association existed between leaf biomass, number of primary branches and pod weight at maturity, as
well as between plant height at flowering and pod weight at maturity. Again, the number of primary branches is
also positive and significantly correlated with plant height, root biomass and leaf length. Furthermore, the
results of dendrogram and minimum spanning tree revealed variations in genetic relatedness and distance,
respectively, which exist among the population of the C. argentea L.

When breeding diploid potatoes, tetraploid progeny can result from the union of 2n eggs and 2n pollen in 2x-2x crosses. Thirty-three crosses were made to examine tetraploid progeny frequency in 2x-2x crosses. All crosses were between S. tuberosum dihaploids and diploid self-compatible donors, M6 and DRH S6-10-4P17. Using chloroplast counting for ploidy determination, the frequency of tetraploid progeny was as high as 45% in one of the 33 crosses. Based upon single nucleotide polymorphism (SNP) genotyping, the tetraploid progeny were attributed to bilateral sexual polyploidization (BSP), which is caused by the union of 2n egg and 2n pollen. Dihaploids were identified that produce lower frequencies of 2n eggs. The results of this study suggest that S. tuberosum dihaploids with a high frequency of 2n eggs should be avoided in 2x - 2x crosses for diploid breeding programs.
This study developed a low cost and affordable to small-scale farmers’ indirect air-cooling combined with evaporative cooling (IAC+EC) system for storage of fruit and vegetables under both arid and hot; and humid and hot climatic conditions. Field heat from freshly harvested produce should be immediately removed through cooling to the desired storage temperature. The aim of this study was to determine the effectiveness of IAC+EC system in terms of the cooling time requirement of the fresh tomato fruit. A fresh tomato cooling experiment to remove field heat during the summer month of September in Pietermaritzburg was conducted for 36 hours where the IAC+EC system was compared to storage under ambient conditions. The results showed that 16 hours was required to reduce the flesh temperature of tomatoes to 16.5°C while the flesh temperature for tomatoes under ambient conditions followed the ambient temperature profile with time of storage. The IAC+EC system reduced and maintained the microenvironment air temperature inside the coolers to 16.5°C - 19°C. The ambient temperature varied between 21 and 32°C. The results in this study are evidence that IAC+ EC system can be a choice for farmers, for cooling the fresh by reducing the field temperature after harvest.
Dioscorea rotundata is a staple food crop for millions of people in the tropical and subtropical regions. In vitro germplasm conservation is a very useful tool in yam improvement strategies but very little is known about the genetic integrity and stability of in-vitro conserved yam plants. In this study, 42 accessions from in vitro and field populations were genotyped using 11 microsatellite markers and 23 morphological descriptors to assess variability within and between accessions. Out of the 23 morphological variables used, 13 were identified as most discriminate and were used to cluster the accessions into 4 clusters using the unweighted pair group arithmetic mean average (UPGMA). Accession maintained in field as well as in in-vitro showed high genetic similarity (R2 = 0.91, p-value: 1e-04). Out of the 42 accessions analyzed, nine accessions maintained in the field and in-vitro displayed different genetic profiles. This study provided basic information on the possible somaclonal variation of yam accessions maintained through in-vitro. Further study with advanced tools such as next-generation sequencing is required to elucidate the nature of the observed variation within clones.
A study was carried out on plant density at the experimental field of the Institute of Agricultural Research for Development (IRAD) Nkolbisson, Yaoundé to determine the appropriate spacing to improve rainfed rice production in the bimodal rainfall forest zone of Cameroon. The experiment was conducted during the main cropping seasons of 2017 and 2018. The planting spacing used were 15cm x 15cm, 20cm x 20cm, 25cm x 25cm and 30cm x 30cm giving the plant populations of 444444, 250000, 160,000 and 111,111 plants / ha respectively using two varieties (Nerica 3 and Nerica 8). The experiment was laid out in a randomized complete block design with three replications. Significant differences were observed in the growth and yield across the years. Treatments were highly significant concerning the number of days to the appearance of the first flower, the number of days to 50% flowering, and the number of days to 50 % maturity. Plants were taller with more tillers and gave higher yields in 2017 than those of 2018. The spacing significantly affected the plant height, number of tillers, and panicle length for both varieties. The interaction of spacing and variety was significant for the number of tillers per m2 and the number of seeds per panicle, however, it was not for the weight of 1000 grains and the percentage of full bales. The yield components determining yield increase were the number of panicles / m2 and the number of seeds/panicles. Nerica 3 variety gave higher yields compared to the Nerica 8, the closer the spacing, the higher the yield. There were a strong significance and positive correlation between yield, number of panicles, and the number of grain per panicle. The spacing that gives the highest number of panicle per m2 was 15 cm X 15 cm and this spacing gave good yield in the region where the study was carried out.

Rubber trees are among the important cultivated crops in Malaysia, and have contributed to the country’s overall economic growth since the 1950s. However, the existing anatomical and morphological studies are relatively insufficient. Currently, Hevea brasiliensis has been cultivated and planted commonly as a commercial planting clone, while Hevea camargoana remains to be a non-cultivated and underutilized rubber species. For many years, there only exists little information both in private plantations and government agencies that have carried out anatomical and morphological assessments on these underutilized species. There is little information about the characteristics of H.camargoana, thus raising the issue among plant breeders on how to best use this underutilized rubber species. This study attempts to investigate the taxonomic values and characteristics of Hevea brasiliensis and Hevea camargoana through anatomical and morphological studies.
Use of distributed electricity generation systems is currently increasing due to their economic and environmental benefits. Agricultural greenhouses require heat and electricity for covering their energy needs while their annual energy requirements vary significantly. Aim of the current work is the investigation of applying various distributed electricity generation systems in greenhouses. A review of different distributed generation systems currently used in various sectors as well as in greenhouses has been implemented. Various technologies are examined utilizing either renewable energies or fossil fuels in very efficient energy systems. Most of them are mature and cost-effective having lower environmental impacts compared with traditional centralized electricity generation technologies. Their use in greenhouses results in many benefits including the creation of an additional income for the farmer, reduction of carbon emissions into the atmosphere and increasing stability of the electric grid. It is suggested that distributed electricity generation systems should be used more in greenhouses when the necessary conditions are favorable.
Grain mold, considered the most important disease of sorghum, is associated with several fungal genera. The disease reduces both yield and quality. In this study, over 300 sorghum seed samples collected from Texas, Florida, and Georgia were evaluated for grain mold severity, seed weight, germination rate, and seed fungal community. Grain mold severity of the seed samples, except for those collected from Cameron, Texas, were rated 3 or higher, indicating that these sorghum lines were moderately susceptible under naturally-infected field conditions during the 2016 and 2017 growing seasons. Seed weight across surveyed locations ranged from 1.1 g to 4.0g for samples collected in Texas during the same period. Percent germination rates for samples collected in Texas ranged from 59.6% to 86.7%. Sorghum samples collected from Florida and Georgia exhibited moderately susceptible response to grain mold infection. Mean seed weight was 1.9 g for samples collected from Florida, while in Georgia, mean seed weight was 2.3 g. Germination rate was low for samples collected from Florida and Georgia. Mycological analysis of sorghum seed samples collected from farmers’ fields in Central and South Texas during the 2016 and 2017 growing seasons showed Alternaria species as the most frequently isolated fungal genus, accounting for 40% and 42 % in 2016 and 2017, followed by Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex. In Florida and Georgia, Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex was the most frequently recovered fungal species, accounting for 77% and 72% of the total. genera/species isolated from seed samples. Other fungal species, including Curvularia lunata, Bipolaris sp., Colletotrichum sublineola, F. verticillioides, Penicillium sp., Aspergillus flavus, F. thapsinum, F. oxysporum, F. sporotrichioides, F. graminearum, F. proliferatum, and Aspergillus niger were also isolated from sorghum seeds in various frequencies. In conclusion, the presence of large number of fungal genera associated with grain deterioration and their effect on other traits, makes management of this disease complex challenging. To identify grain mold resistant sources in a region, using the most dominant species in that region to screen the sorghum germplasm is recommended.
Potato is the second most important food crop in Kenya after maize. It is a valuable cash and food crop mainly grown by small-scale farmers. Potato is cultivated mainly under rainfed production conditions at altitudes between 1500 and 3000 metre above sea level (masl). Consequently, National Performance Trials (NPTs) test sites are located in these highlands. Recently, potato production has spread to the mid-highlands (1200-1500masl) mostly due to high food demand occasioned by population increase, and migration of small scale farmers from the densely populated highlands to the more spacious midlands. Consequently, there is increased need to breed potato varieties that can grow profitably in the warmer mid-altitudes. This development called for identification of new conventional NPT test sites located in the mid-altitudes. Six mid-altitude sites were identified and client-managed conventional NPTs carried out. Twenty six potato genotypes were evaluated for two seasons. First season crop was planted in 2016 while the second season crop was planted in 2017. There was a significant (p≤ 0.001) effect of genotypes, environments and genotype x environment interaction in the first season. Trans-Nzoia was the highest yielding site. All genotypes yielded between 10 and 25 ton/ha. In the second season, only environments showed significant (p≤ 0.001) effects. Again, Trans-Nzoia was the highest yielding site. Across the two seasons, Trans-Nzoia gave an average yield of 26.96 ton/ha followed by Kabete at 18. 21ton/ha. All the other four sites yielded less than 10 ton/ha. The high yields at Trans-Nzoia and Kabete could be due to higher altitudes in these two sites compared to the others. In order to develop potato varieties that can produce profitably in the warm mid-altitudes, breeding and early generation selections activities should be based in these areas.
The tests for the evaluation of seedling establishment, palatability and acceptability were carried out at the Teaching and Research Farm of the Department of Agricultural Technology and the Food Laboratory of the Department of Home and Rural Economics, Adamawa State College of Agriculture, Ganye, Adamawa State. The experimental designs used were Randomized Complete Block Design and the Completely Randomized Design. Some of the parameters measured were percentage seedling establishment, palatability, and acceptability tests. The highest mean percentage seedling establishment was observed in 12.00g levels of H. suaveolens whole powder treated shelled groundnut seeds (97.67, 97.00, and 94.00) at the three periods of storage. Percentage seedling establishment decreased with a decrease in levels of H. suaveolens whole powder. One of the major constraints to the use of plant materials as an alternative to synthetic insecticides is the issue of standardization in dosage of application. This work has suggested that, if groundnut seeds are to be used for sowing, they should be stored with a 12.00g level of H. suaveolens whole powder for every 300.00g for three months. However, if they are to be used for consumption, they could be stored with a 6.00g level of H. suaveolens whole powder for every 300.00g for at most three months. There was no significant difference between treated and untreated shelled groundnut seeds at the three periods of storage on the acceptability and palatability score of cooked groundnut at all dosages of application. All treatments were within the acceptable score rates even though the two rates of the synthetic insecticides, actellic dust were at the lowest acceptable score rate. The finding also showed that acceptability and palatability decreased with an increase in dosage of application. The periods of storage also had a significant impact on the mean percentage seedling establishment. It was observed that there was a higher percentage of seedling establishment when shelled groundnut seeds were stored from November- January. At this period of the year, the temperature and humidity are usually low and this might have necessitated the high state of inactivity and low performance of the bruchids compared to other periods of storage within the year.
Irrigation experiments of cocoa tend to concentrate on yield of matured cocoa trees compared to field establishment of young seedlings. Seedling survival leading to optimum population density are fundamental to obtaining maximum yield of crops. The aim of this experiment was to determine the effect of mulching and irrigation on survival of hybrid cocoa clone raised in three different growing media during the establishment phase. The experimental design was a 2 x 2 x 3 factorial arranged in a split-split plot design, with irrigation as the main plot factor, mulching as the subplot factor and growing media as the sub-sub plot factor with three replications. Cocoa pod husk (CPH) was used as the mulching material and each plant received 5kg at a rate of 5.6 t/ha. Irrigation was done daily by applying 4L of water except when it rains. Data was collected on soil moisture, plant height, leaf number, stem girth and plant survival. Results indicated that irrigation and mulching significantly (P<0.01) enhanced soil moisture. Cocoa seedlings raised in topsoil, mulched and irrigated significantly (P<0.05) increased survival rate (94.5%) compared to seedlings raised in soil without irrigation and no mulching (47.1%). Similarly, the survival rate of seedlings raised in growing media M2, mulched and irrigated (93.0%) was significantly (P<0.05) higher than similar seedlings without irrigation (73.4%). However, the survival rate of seedlings raised in M3 without mulching but irrigated was significantly (<0.05) higher 92.1% compared to seedlings raised in M3 mulched and irrigated 67.1%. Irrigation is very important in ensuring high survival rate during early field establishment. Mulching with cocoa pod husk without irrigation did not improve cocoa seedling survival.
Few years ago National Centre for Agricultural Mechanization (NCAM) launched melon sheller to reduce burden of obtaining melon oil and cake, and to enhance rural women’s productivity. This study looked at the productivity of promoted melon shelling technology and preference by rural women in Nigeria. Data were gathered from the NCAM workshop and survey of melon processors in Niger State. In the workshop, it was found that time allowed for soaking melon and covering with piece of clothes contributed to the productivity of the sheller. Results from survey revealed that 95.1% of the respondents’ preferred Internal Combustion technology and 90.2% liked electric-driven melon shellers over the manual one. Also, 69.5% obtained the shellers from local fabricators rather than NCAM. The technology led to increased turnout of melon (378kg/hr) and reduced wastages to 1.26kg out of 75.6kg. The study concluded that the promoted melon sheller is efficient and have positive implication on the rural women’s productivity and revenue. The study recommends that the rural women should put the melon sheller into its maximum capacity use. The NCAM should extend training to the local fabricators so that they can improve on the technology most especially in the areas of winnowing and washing of melon kernels.
Keeping in view of lack of recommended rates of N and NPS fertilizers, a field experiment was conducted to evaluate the effect of the newly introduced NPS fertilizer and nitrogen on growth, physiology and above ground biomass of garlic. Four NPS (0-0-0, 78.75-69-12.75, 105-92-17 and 131.25-115-21.25 kg N-P-S ha-1) and three nitrogen fertilizer rates (114.13, 228.26 and 278.33 kg N ha-1) were laid out in Randomized Complete Block Design with three replications. Significantly highest plant height (28.02 cm), leaf diameter (1.27 cm), dry and fresh weight (4.71 g and 6.11 g) and leaf length were recorded on garlic plants supplied with 105-92-17 kg N-P-S ha-1 and also the highest plant height (27.75 cm), leaf length (24.02 cm), fresh and dry weight (6.23 g and 5.04 g) were recorded on garlic plants supplied with 278.33 kg N ha-1. The interaction effect also show a significant effect in almost all the growth parameters; the early day to 50% emergence was recorded from a plot which received 228.26 kg N ha-1 and 105-92-17 kg NPS ha-1 and the highest plant height, leaf length, fresh and dry above ground biomass and leaf diameter were 29.62 cm, 25.60 cm, 6.93 g, 5.59 g and 1.4 cm, respectively were observed by the interaction of 278.33 kg N ha-1 and 105-92-17 kg N-P-S ha-1 with no significant difference with 228.26 N and 78.75-69-12.75 kg N-P-S ha−1. From this one season experiment, fertilizer rates 307.01-69-12.75 kg N-P-S ha−1 could be recommended for garlic production.
In the past, conservation effort has primarily focused on establishment of forest reserves for timber production, with minimal or no consideration to how these natural resources will help sustain or improve livelihoods of adjoining communities. This study examined the contribution of Aramoko forest reserve to the livelihoods of the adjoining communities in Ekiti State. One hundred and twenty pre-tested questionnaires were administered among the products collectors in the study area. Data collected were analysed and the result showed that 78.3 % of the respondents are married with 52.3 % of them male, while 50.8 % of the respondents aged between 51-70 years with 64.1 % having at least secondary education. Twenty-five (25) different products were collected by the respondents in the study area. These products include among others; timber with highest frequency of (120) followed by herbal plants (115), Archantina marginata (105), Thaumatococcus danielli (89), Bridelia ferruginea (70) and Irvingia garbonensis (65). The use of motor cycle accounted for 41.4 % of the respondents means of transportation, while 31.3 % of the respondents sell their product in bit at the village market. Picking, digging, plucking, cutting and uprooting were methods used for harvesting by the respondents while illegal felling (24 %) and indiscriminate bush burning (22.4 %) were the major conservation problem in the study area. Specifically, some of the products harvested are used for food, medicine, fuelwood, herbs and cultural purposes. The study recommends that research should be conducted into how these products can be artificially raised in the nursery for plantation establishment.
Cocoa farmer faces increasing challenging environment through exposure to risks factors which have impacted negatively on their production or output. Since farmers are primary producers and often times lack capacity to control risks factor, it is important to manage this factors. This study examines the cocoa farmers’ risk preferences and crop insurance perception and isolates the drivers of decision to uptake crop insurance among cocoa farmers in Ekiti state. The sample for the study consist of 200 cocoa farmers who were household heads selected through multi-stage sampling across four Local government areas of Ekiti State who are predominantly cocoa producers. Data collected on socio-demographic characteristics, perception of crop insurance and risk preferences, were analyzed using descriptive statistics and binary logistic model. Results showed that majority of the cocoa farmers were without crop insurance, with higher enrolment in Membership of cooperative society, owned their land, larger household size and lower educational level but higher level of farm experience when compared to cocoa farmers who are holding crop insurance. Farmers risk preferences showed no significant difference between farmers with or without insurance. Education (β=0.59), Household size (β=0.0029) and Debt use (β=0.02), Membership of cooperative (β=-4.53), Farming Experience (β=-2.51), Owned Land (β=-2.19) and Non-Farm Income (β=-0.65) were among the significant determinants of insurance uptake. Risk mitigating measures such as provision of necessary incentives such as improved varieties of cocoa seedling, as well as provision of fertiliser and approved pesticides, financial assistance, and simple processing technologies that produce standard cocoa bean plus a re-jigged Nigeria Agricultural Insurance Corporation (NAIC) for an improved discharge of its function are recommended.
Mitigation of climate change requires the decrease of greenhouse gas emissions into the atmosphere and the increasing use of renewable energies replacing fossil fuels. Agricultural greenhouses are energy-intensive agricultural systems using mainly fossil fuels. The use of renewable energies during their operation is limited so far. The possibility of using renewable energies for covering their energy needs has been investigated, focused on the Mediterranean region. Various sustainable energy technologies which are reliable, mature, cost-effective and broadly used in various applications are examined. These include solar-PV systems, low enthalpy geothermal energy, solid biomass burning, co-generation systems, high efficiency heat pumps and reuse of rejected industrial heat. Combined use of these systems in greenhouses can cover all their energy requirements in heat, cooling and electricity, reducing or zeroing their net CO2 emissions into the atmosphere due to operational energy use. It is concluded that depending on their local availability in Mediterranean countries, these benign energy technologies can assist greenhouse crop growers in the reduction of their carbon emissions, contributing in the achievement of the universal goal for climate change mitigation.
Field experiment was carried out under rain-fed conditions during the 2013 and 2014 cropping seasons at the Teaching and Research Farm of the Department of Agricultural Technology, Adamawa State College of Agriculture, Ganye, solely to develop an integrated pest management for the control of groundnut Aphid (Aphis craccivora Koch) [Homoptera: Aphididae]. The experimental Design used was the Randomized Complete Block Design (RCBD). Parameters measured were, average number of leaves per plot at 6 weeks after sowing, number of branches at 3 weeks after sowing, number of branches at 6 weeks after sowing, number of pods per plot, weight of harvested seeds per plot. The result obtained shows that, there was significant difference among the treatments in all the parameters measured at 0.05 level of probability using the Least Significant Difference (LSD). According to the results recorded, the highest mean yield of groundnut was obtained on plots treated with the combination of chemical and physical control methods (1444g) followed by plots treated with physical, chemical and cultural control methods combined (1296g). The highest mean number of pods per plant was recorded in the combination of physical, chemical and cultural control methods (18.00) followed by chemical and physical control methods as combined (15.00). The work shows that, the cultivation of groundnut with the control of groundnut Aphid (Aphis craccivora Koch) using integrated pest control applied as recommended facilitates better growth and guarantees good crop yield. The use of physical, chemical and cultural control method is profitable in Ganye Area of Adamawa State and is therefore suggested for use to local farmers.
Rice (Oryza sativa L.) is one of the most important food crops in the world. Purple rice, as a special rice with important nutritional and health functions, has important scientific significance and application value for genetic improvement of purple rice and breeding of new varieties through in-depth study on its agronomic and related quality traits and products processed, and analysis of its genetic basis. In this paper, the new progress of purple rice in agronomic traits, quality traits, environmental impacts on purple rice and genetic basis of purple rice seed coat in recent years were reviewed and analyzed, and the application prospects of purple rice processing products and purple gene in rice genetic improvement were also prospected. Thus, our results will provide important information and reference for breeding new purple rice varieties with good quality and high yield.
Besides the lack of soil fertilization, the primary biotic stressor limiting the production of cocoa (Theobroma cacao L.) in Indonesia is pest and disease attacks (PDAs). As a part of the efforts to find out the appropriate solution for the farming constraints, a field trial was carried out for 14 months (2015 – 2016) in Genggelang - North Lombok Regency, Indonesia. The main objective of the experiment was to identify the effects of the use of locally-available materials, i.e., liquid-silicate rock fertilizer (LSRF), botanical pesticide (BP) of neem, and black ants (BA) of Doliccoderus thoracic, on PDAs, bean production, and polyphenol and lignin contents of cocoa pod shell. A randomized complete block design was laid out in three blocks, and the treatments were LSRF, LSRF+BP, LSRF+BA, BA, and control. Results reveal that the application of those materials reduced the intensity of pest and disease attacks (e.i., respectively, 6 - 24 % and 3 - 9 % lower than for that of the control), increased 18 – 119 % of bean production, and improved the polyphenol and lignin contents of pod shell. The highest increase (119 %) of bean production was due to the foliar application of LSRF. The positive effect of the treatments, especially the use of LSRF, associated with the improvement of the resistance of cocoa to PDAs and appropriate supply of plant-essential nutrients. Therefore, the foliar application of LSRF may be promoted as a proper method to improve the production of cocoa, especially of that grown on less fertile soils.
Seventeen sesame genotypes were tested at ten environments in Tigray, Northern Ethiopia during 2014-2015 cropping seasons. Randomized Complete Block Designs (RCBD) with three replications was used in the study. According to the GGE bi-plot different sesame growing environments grouped into two mega-environments: The first mega-environment contained the favorable environments Dansha area with a vertex G4 and Sheraro area with winner G3 and the second environment included medium to low environments E2 (Humera-2), E4 (Dansha-2), E5 (Sheraro-1), E7 (Wargiba-1), E8 (Wargiba-2) and E9 (Maykadra) for seed yield. Three mega-environments identified for oil content: The 1st environment contained G12, G7 and G2 in the mega-environment group of Humera, Dansha and Gendawuha, The 2nd environment, Sheraro location contained G9 and the 3rd environment Wargiba, was containing G17. G1 (HuRC-4) identified as an “ideal” genotype and E1 (Humera-1) also identified as an ideal environment the most representative of the overall environments and the most powerful to discriminate genotypes. The multivariate approaches AMMI and GGEbi-plot were better for partitioning the GEI into the causes of variation. According to different stability models, G1, G7, and G3 were high yielder and the most stable both in terms of seed yield and oil content. Moreover, showed yield advantages over the released and local varieties. The stable genotypes recommended for wider areas while G14 and G4 were for specific favorable environments Sheraro and Dansha, respectively.

increasing from time to time and most of the recently released varieties accounts largest area coverage [10]. Despite
an increase in the area of coverage, the productivity of onion variety in Ethiopia is much lower than the expected
production level. The low productivity could be attributed to the limited availability of quality seeds and associated
production technologies used among the others. Onion cultivars vary in their susceptibility to flower stalk
development, depending on climatic conditions and their genetic background [11].
The overall seed production performances of the released onion varieties with the aim to play a significant role
in solving the chronic seed shortage in the area and also in the country, and to exploit onion seed production and
productivity capacity were not identified. Nevertheless, little information is available on onion seed production
potential of varieties in the study area done on Nafis variety with fertilizer rates on seed production and quality [12].
Therefore, the presented study was designed to evaluate seed production potential of different varieties to come up
with relevant recommendations that will help farmers for better onion seed production to the area.
2. Materials and Methods
2.1. Description of the Study Area
The study was conducted at Kulumsa Agricultural Research Center (KARC) which is located at 8°00‟ to
8o02‟N and 39°07‟ to 39°10‟E and an altitude of 2210 m a.s.l. in Oromia. KARC has a low relief difference with
altitude ranging from 1980 to 2230 m. The agro- climatic condition of the area is wet with 811mm mean annual rain
fall and it is a uni- modal rainfall pattern with extended rainy season from March to September. However, the peak
rainy season is from July to August. The mean annual maximum and minimum temperatures are 23.1 and 9.9°C,
respectively. The coldest month is December whereas; May is the hottest month [13].
2.2. Experimental Materials and Bulb Production
Five released varieties of Onion; namely, Nafis, Robaf, Nasic Red, Bombe Red and Adama Red variety was
used for the experiment. The seedlings were raised on seed bed at nursery site. After 45 days, seedlings were
transplanted to the field for bulb production. Seedlings were transplanted with a recommended double row spacing
of 40 cm × 20 cm × 5 cm [2]. All the recommended agronomic and crop protection practices such as cultivation,
fertilization, weeding and fungicide/pesticide application were applied according to the national recommendations
for onion. Once the onion is matured, bulbs were harvested and true to type bulbs which are healthy, well-shaped
and size were selected for the experiment. Also, prior to planting, one fourth of the bulb tops were sliced off to
promote sprouting [14].
2.3. Experimental Design and Procedure
The experiment was conducted under irrigation condition during the off- season using randomized complete
block design (RCBD) with three replications. The sprouted onion bulbs were planted in double rows with spacing of
60, 40 and 20 cm between water furrows, rows and plants in rows, respectively [2]. Distances of 1 and 1.5 m were
maintained between plots and blocks, respectively. A plot size of 3.2 m × 2.8 m (8.96 m2) was used for treatments.
Each plot had four rows (ridges) which consisted of 112 plants. The middle double rows were considered for
recording of data. Recommended amount of fertilizer (200kg/ha DAP & 100kg/ha Urea) were used, Urea as nitrogen
source and NPS as phosphorous for each plot. The site was irrigated at the interval of three days during the first
phase of active growth of the plant. Later, the irrigation gap was increased to seven days interval [2].
2.4. Data Collection and Measurement
Days to bolting: This was recorded as the number of days from date of planting up to when 50% of the plants in
a plot produced flower stalk.
Days to 50% flowering: This was recorded as the number of days from date of planting up to when 50% of the
flower stalks in each plot produced flowers.
Days to maturity: This was recorded as the number of days from date of planting up to when 50% of the plants
in each plot matured or ready for harvest (when the seed colour changed to black or the capsule turned brown and
started splitting).
vigorousity (1-9 scale): this parameter was taken subjectively by scale (1-9 scale)
Plant height (cm): This refers to the mean height of five randomly selected plants from the central rows from
each plot. It was measured from the soil surface to the tip of the plant after development of umbels of the plant.
Flower stalk diameter (cm): This was measured for five randomly selected plants from the central rows from
each plot at flowering stage and the average was calculated to record the parameter.
Flower stalk height (cm): measured for five randomly selected plants from the central rows from each plot at
flowering stage and the average was calculated to record the parameter.
Number of flower stalks per plant: Numbers of flower stalks of the five randomly selected plants per plot
from 4 double central rows was counted and the average calculated and recorded as the number of flower stalks per
plant.
Number of umbels per plant: Numbers of umbels from the five randomly sampled plants was `counted and the
average calculated and expressed as the number of umbels per plant.
Umbel diameter (cm): This refers to the mean umbel diameter of the five randomly sampled plants in each
plot. The diameter was measured using a ruler or a caliper two times measuring in two opposite direction (north-
south and east to west).

Number of seeds per umbel: Five umbels were randomly taken from the five randomly sampled plants in each
plot, dried, threshed and then counted to obtain number of seeds per umbel.
Seed yield per umbel (g): Five randomly sample umbels were harvested, dried, threshed to determine seeds
weight per umbel and adjusted to a moisture content of 8%; the average weight of seed per umbel was calculated by
dividing the total weight of seeds to number of the umbels.
Seed yield per plant (g): Five randomly sample plants were harvested, dried, threshed to determine seeds
weight per plant and adjusted to a moisture content of 8%; the average weight of seed per plant was calculated by
dividing the total weight of seeds to number of the plants.
Seed yield (kg ha-1
): The yield was estimated from seed yield per plot. The converted to hectares in kilograms.
1000 seeds weight (g): Sample of seeds from the bulk in each plot was taken and 1000 seeds were counted in
seed counter machine and weighed using a sensitive balance and then adjusted to the moisture content of 8%.
Germination (%): One hundred seeds were placed on Petri dishes covered with filter paper and allowed to
imbibe distilled water which was kept at room temperature until 15 days. The percent of germination has three
replications using the total of 48 Petri dishes. A seed was considered germinated when the radicle protrusion attained
approximately 1mm. Then percent germination was determined from counts of normal seedlings and the total seeds
placed on Petri dishes. Percent of seed germination were done after harvest.
Germination (%) = Number of germinated seed 100

3.2. Stalk Formation Date
Days to stalk formation date was statistically non- significantly (P<0.05) affected by the variety. Bombay Red
onion variety forms early (about 4 to 3 days earlier) when compared to others variety (Table 1). There was no
significant difference among varieties, this mean that varieties cannot vary in their susceptibility to stalk formation
date depending on climatic conditions and their genetic backgrounds to the area. Stack formation may be a problem
of physiological nature and is undesirable for better production and onion varieties can differ in percentage of stack
formation [16].
3.3. Days to Bolting
Days to bolting was statistically non-significantly (P<0.05) affected by the variety. Bombay Red onion variety
bolted early (about 5 to 8 days earlier) when compared to the Nafis variety (65 days) (Table 1). Those onion varieties
have no significant difference among varieties can vary in their susceptibility to bolting, depending on climatic
conditions and their genetic backgrounds. In average the result confirmed with report of Getachew [8] days to
bolting of Bombey red onion variety was between 63-67 days. In contrast differences of results to other findings in
the number of days required for stalk formation could be due to the relatively cool climatic condition of the
experimental site compared with Melkassa condition.
3.4. Days to 50% Flowering
Varieties showed significant difference on days to flowering. The longest (85) and earlier (74, 77) days to
flowering was shown in Nafis and Adama red & bombe red respectively (Table 1). This indicated that Nafis took
4. Journal of Agriculture and Crops
36
longer days to flower while Bombe red and Adama red flowered earlier. Earliness or lateness in the days to 50%
flowering might have been due to the inherited characters, early acclimatization to the growing area to enhance their
growth and developments. This result was in agreement with the finding of Seleshi, et al. [17] who reported that
days to flowering was significantly affected by the interaction effect of variety and location which could be due to
the temperature of the growing area.
3.5. Vigourisity (1-9 Scale)
Varieties showed significant (P<0.05) difference between varieties on vigoursity. Nafis variety was more
vigourious (7.33) than Bombe red variety was the lowest, while others varieties were statistically non- significant
difference among them (Table 1).
3.6. Plant Height (cm)
Plant height has no-significantly (P<0.05) influence due to Varieties for onion seed production. The mean plant
height of the onion varieties (55.23 cm) among the evaluated varieties at the locations (Table-1). There was no
significant difference among varieties, this mean that varieties cannot produce significant difference on plant height
depending on climatic conditions and their genetic backgrounds to the area. In concurrent to the present findings,
Muhammad and Abdul [16], Islam, et al. [18] and Jilani, et al. [19] found significant genotypic variation among
onion varieties in plant height.
3.7. Seed Maturity Days
Days to maturity were other growth parameters of seed onion. As indicated in Table 1, non-significant (P<0.05)
difference was observed on seed maturity days of different onion varieties for onion seed production. The longest
and the earlier seed maturity days were observed on Adama red and Bombe red which is 175 days and 155.67 days
respectively. The results indicate that, the traits are not affected by both genotype and environment.
3.8. Number of flower Stalks per Plant and Height (cm)
The number of flower stalks peer plant was statistically non-significance (P<0.05) difference between the
varieties, this mean varieties were not affected by the environment and genotypes to produce flower stalk per plant.
Varieties showed significant (P<0.05) difference on flower stalk height. The Nasic red variety was the longest
(73.93cm) and Robaf variety produce the shortest flower stalk (65.47cm) (Table 1). The number of flower stalks per
plant varied from1 to 15 per plant at Melkassa and the terminal number of 50-200 flowers produced per umbel of
Adama Red variety depending on the number of shoots axis [2]. The result was in accordance with Tamrat [7] and
Debashis, et al. [20] who found stalk heights for other cultivar of onion in the range of 76-93 cm which was similar
to height recorded in the present study.

of Variation
3.9. Flower Stalk Diameter (cm)
Flower stalk diameter was significantly (P<0.01) influenced by varieties. Nafis, Robaf and Nasic variety were
shows the highest about 2.3 cm flower stalk diameter, while Bombay Red and Adama Red onion variety shows the
lowest in flow stack diameter. But Nafis, Robaf and Nasic were statistically non-significant between them (Table 2).
This might be because of onion varieties may have different morphological and biochemical characteristics that
affect the vegetative parts, as reported [16, 21].
3.10. Number of Umbel per Plant
Significant (P<0.05) differences were observed between varieties on number of umbel per plant, due to the
effect of varieties. Adama Red onion variety shows the highest (10.39) number of umbel per plant than other
Varieties, while others all varieties show statistically the same number of umbel per plant (Table 2). Results on the
number of umbels per plant also followed similar trend to the number of flower stalk per plant [16]. And also
increase in NP fertilization, increases number of umbels and flower stalks per plant reported [7, 22].

3.11. Umbel Diameter (cm)
Umbel diameter was significantly P (<0.05) affected by varieties. Nasic red gave the highest umbel diameter
(5.56cm) followed by the Adama red variety (5.18cm) with no significant difference between the two means. The
lowest umbel diameter was recorded from Bombe red variety (4.58cm) and interacted with the Nafis variety (Table
2). The performance of a onion cultivar mainly depends on the interaction of genetic makeup and environment [16].
3.12. Number of Seed per Umbels
The highest number of seed per umbel was recorded by Adama red (763.5) and Nafis (744.70) variety and this
was statistically similar with other varieties, this mean that the varieties shows that non-significant (P<0.05)
differences on number of seed per umbels, but this can affect directly the total seed production (Table 2). Results on
the number of umbels per umbel also followed similar trend to the number of flower stalk per plant. The number of
seed per umbels produced by a single plant usually varies, depending on the number of branches formed on the shoot
axis during vegetative growth [23].
3.13. Seed Yield per Umbel (g)
Seed yield per umbel was significantly (P<0.05) shows difference between the varieties. The highest significant
seed yield per umbel was Adama Red variety (2.82g) than other varieties. This mean that other varieties as Nafis,
Robaf, Nasic red and Bombe red were shows statistically the same seed yield per umbel (Table 2). Seed yield per
umbel increased linearly on cultivars with increases in set-size [16].
3.14. Seed Yield per Plant (g)
The effect of varieties showed the non- significantly (P<0.05) seed yield per plant, with no significant difference
among them. The lowest seed yield per hectare was obtained from the plots with which did not vary significantly
(Table 2). Onion cultivars varied significantly with respect to seed yield per plant due to genetic inheritance [21].
3.15. Seed Yield per Hectare (kg ha-1
)
The seed yield showed significantly (P<0.05) affected by varieties. The highest significant seed yield (1416.31
kg ha-1
) was observed by Adama Red variety. The least seed yield was obtained from Robaf variety, but statistically
similar with other varieties without Adama red varieties (Table 2). Some of those parameters were directly correlated
with the finding of Seleshi, et al. [17], seed yield were related with flowering characters like bolting period, umbel
size, number of flower stalks/plant, flower stalk diameter and thousand seed weight had a direct positive influences
on seed yield and these parameters are therefore recommended for selecting cultivars for high seed yield potential
under Melkassa conditions. The current result was in accordance with the findings of Demis, et al. [12] on fertilizer
application on Nafis Variety, the maximum seed yield per hectare was found from the combination application of N
and P gave the highest seed yield (1858.82 kg ha-1
) for onion seed.
3.16. Thousand Seed Weight
The highest 1000 seed weight was recorded by Adama red variety but statistically non-significant difference
between other varieties. The lowest thousand seed weight was recorded from Nasic (Table 2). Cultivars varied
significantly from each other with respect to leaf
A cultivar performs differently under diverse agro-climatic conditions and various cultivars of the same species
grown even at the same environment often yield differently. Ali, et al. [24], also reported no significant variation in
the weight of 1000 seeds among different varieties.
3.17. Germination Percentage
Germination percentage was statistically non-significantly P (<0.05) affected by varieties. Bombe red variety
gave the highest germination percentage of seeds (85.67%) followed by Adama red (85.33%) with no significant
difference between the two means. The lowest germination percentage (64.67) was obtained from Nasic red (Table
2). Demis, et al. [12] reported that as the rate of phosphorous increased, percent of seed germination 30 days after
harvest was increased on Nafis variety. And also application of fertilizers gave highest germination percentage of
onion seeds compered to unfertilized treatment [8].
4. Conclusion
The results of this experiment indicated that the variety significantly affected by most of yield and yield
contribution as flowering date, flower stalk height and diameter, number of umbel per plant, umbel diameter, seed
yield per umbel and seed yield per hectare. The highest seed yield per plant (8.87 g) and per hectare (1415.89 kg/ha)
was obtained from Adama red variety which was followed by Nafis variety (1157.17kg/ha), this result were related
with number of umbel per plant and also seed yield per umbel thus, Adama red variety was significant difference for
those yield contributing parameters. On the other hand, the highest 1000 seeds weight (4.54 g) was also recorded
from Adama red variety. Therefore, it can be concluded that use of the improved onion varieties of Adama red is
advisable for onion seed production in the test area and also alternatively followed by Nasfis variety which have high
germination percentage with former variety.
