Gram Pod borer (Helicoverpa armigera Hubner) is the most imperative constraint in chickpea (Cicer arietinum L.) production causing severe losses or there may be complete crop failure in spite of several rounds of insecticidal applications. The present study was designed to investigate the effect of neem application in controlling Pod borer on six different genotypic varieties (AZ-CM2, AZ-CM4, AZ-CM6, AZ-CM10, AZ-CM12 and Noor-91). The experiment was designed in a Split-Plot Design with three replicates. Different agronomic traits were recorded such as plant population, plant height, percentage flowering, physical maturity, number of pod per plant, infestation of pod borer and yield of chickpea. The results showed that plants treated with neem have high population (maximum in Noor-91 with 16.8 plants/m2 and minimum in AZ-CM12 with 2.9 plants/m2, plant height (46.7 cm in AZ-CM4 and 34.7cm in Noor-91), flowering (AZ-CM10 gave 50% flowers after 100.3 days), physical maturity (AZ-CM4 took maximum time (139.7 days) to attain 90% physical maturity while AZ-CM2 and AZ-CM4 took only 136.0 days to attain 90% physical maturity), average number of pods (Noor 91 has higher 19.4 and AZ-CM2 has lowest 12.1). Infestation of pod borer and % damage was found lower in neem sprayed plant. Overall highest yield was observed in plants treated with neem as compared to control and genotype dependent. It is concluded from the results that neem application has a significant effect in controlling pod borer and this effect varies from genotype to genotype. Noor-91 was found to be more resistant towards pod borer.

Sphaeranthus suaveolens is a weed from the family Asteraceae, it grows abundantly in wet areas and is most common in rice fields. The extracts from plants closely related to S. suaveolens have been reported to have allelopathic, insecticidal, antifeedant, repellent, and other biological activities. Currently, the use of synthetic chemicals to control weeds and insect pests raises several concerns related to the environment and human health. Extracts from plants with pesticidal properties can offer the best and an environmentally friendly alternative. Some of these extracts have been extensively tested to assess their applications as valuable natural resources in sustainable agriculture. This review article, therefore, explores the potential of S. suaveolens extracts in controlling insect pests and managing weeds by smallholder farmers.

The wheat aphid species individually and collectively cause severe damage to the wheat crop qualitatively and quantitatively. The incidence of these aphids is influenced by a number of biotic factors such as host plant resistance, availability of the natural enemies and the major abiotic factors such as temperature, humidity and rainfall. In the present investigation, the incidence and abundance of wheat aphid species were recorded with rapeseed as a perimeter crop. The results showed that wheat was infested by two major aphid species, bird cherry oat aphid, Rhopalosiphum padi and green peach aphid, Myzus persicae with rapeseed as a perimeter crop. The results further suggested that the level of infestation in wheat with perimeter crop remained low compared to check, influenced by the presence of natural enemies, however, the level of infestation of M. persicae remained highly influenced by the high level of infestation in rapeseed. In light of the above experimental results we concluded that the rapeseed influenced the population of R. padi and deterred S. avenae, however, encouraged M. persicae to infest wheat crop.

Occurrence and Extent of Fusarium Head Blight on Wheat Cultivars in SomaliaPremier Publishers
This study was aimed to evaluate the disease incidence and severity of Fusarium head blight (FHB) on wheat cultivar commonly cultivated in Somalia. To execute this study, four commonly grown wheat cultivars e.g., edessa, ceyhann99, kasifbey, and gündaş were cultivated in two different seasons (winter and summer) maintaining the good agricultural practices. Results revealed that the highest percent of Fusarium head blight disease incidence was observed in kasifbey (65%) cultivar followed by edessa (40.13%), ceyhann99 (28.75%) and gündaş (13.75%). The disease severity and disease index of Fusarium head blight was varied significantly among the wheat cultivars and the highest percent was recorded on the kasifbey cultivar as 61.63% and 39.50%, respectively while the lowest was observed on the gündaş (13.18% and 1.88%, respectively). The maximum grain severity among the cultivars was recorded on the edessa (4.01%) whereas the minimum was on the gündaş (0.92%). The gündaş was experienced to yield better than the other cultivars and performed better resistance against the Fusarium head blight disease of wheat, however, special intervention should be taken to protect the wheat from Fusarium head blight disease.

Among avian pests, house sparrow caused serious depredations, not only to seeds, but also seedlings of various crops particularly in the organic farming. Different mechanical and chemical ways have been reported to manage these losses all over the world. The present study was aimed to investigate the efficacy of two bird repellents namely methylanthranilate and anthraquinone to manage the depredations of wheat seeds and seedlings against house sparrow in captivity. For this purpose house sparrows were offered with treated and untreated seeds and seedlings of wheat in two aviaries. By providing treated seeds and seedlings with these repellents, the relative effectiveness was appraised by comparing the consumed and unconsumed seeds and seedlings. Feeding responses of these birds against different doses of these repellents were investigated with the help of the closed circuit cameras adjusted in the aviaries. During the whole experiment among trial and control group highly significant differences (P<0.01)><0.05)>0.05) variance when wheat seeds and seedlings were offered to house sparrows. House sparrows were influenced more quickly by consuming wheat seeds and seedlings treated with both repellents. Sparrows displayed noticeable head-shaking and feather ruffling behavior by consuming the treated seeds and seedlings.

Human health and environment are greatly affected by extensive used of synthetic insecticide, which is why the alternative way of pesticides, such as botanical pesticide consumption increase with the passage of time to control of insect pests. The insecticidal impact of Moringa (Moringa oleifera), Neem (Azadirachta indica) and Euclyptus (Eucalyptus globules) leaves extracts were investigated on Diurophous noxia (Hemiptera: Aphididae). This study was aimed to evaluate the efficiency of bio-pesticide instead of synthetic chemicals against D. noxia. Experimental results showed that the percentage of mortality fluctuate with the fluctuation of concentration with time intervals and have great impact on the population of D. noxia. Single, doubled and tripled combinations of leaves extract were tested at two different concentrations (25 and 50%). The results suggested and concluded that from all the application of single botanicals A. indica give better result as compared to other single application while application of double combination M. olerifera with A. indica give significance result instead of other double mixture, meanwhile the triple combination (M. olerifera, A. indica and E. globules) performed excellent result as the others triple mixtures. The study revealed that combine used of M. olerifera, A. indica and E. globules leaves extract were very effective against D. noxia and surge as an alternative way of pesticides instead of synthetic chemicals.

The efficacy of Alchornea cordifolia leaf powder was investigated against cowpea beetle, Callosobruchus maculatus on stored cowpea in the laboratory. The tested leaf powder was added as admixtures to 20 g of cowpea grains at the following rates of at 0 (control), 3, 4, and 5g % (w/w) while in the control treatment there was no plant material added. Each of the treatments was tested by exposing five pairs of adult beetles in a Completely Randomized Design (CRD) to assess oviposition deterrent and egg hatching suppression by the plant material. The results showed that oviposition and percentage egg hatched were significantly (P <0.05) suppressed on seeds treated with higher dosage level of the powder. Leaf powder with the concentration of 5g% (w/w)/20g cowpea seeds was most effective in suppressing oviposition and egg hatched. Thus, the result revealed that A. cordifolia leaf powder has oviposition deterrent and ovicidal properties and as such can be used as an alternative to synthetic insecticides for controlling C. maculatus infestation on stored cowpea grains. Therefore A. cordifolia leaf powder can be incorporated into traditional storage pest management as well as integrated pest management and it may strongly recommended in developing countries.

Methodological approach to indigenous fruit trees breeding: case of Dacryodes...Innspub Net
Very little work has been done forthe varietal improvement of indigenous fruit trees. Controlled cross pollination tests were
conducted on Dacryodes edulis to assess the influence of the origin of the male parent and the type of flower that produced
pollen used for fertilization on the fruiting efficiency of 14 well-known females’ accessions from three provenances. The
crossbreeding test was performed following a full nested mating design. The experimental design included provenance as a fixed factor, treatment as within-subject (i.e. repeated measures) fixed factor and plant individual as a random factor (subject).The results showed that the fruiting index that determines the species’ yield varies significantly (p = 0.010) with the combined actions of the three factors studied which were (i) the provenance of the male parent; (ii) the pollen type used for hand fertilization (pure male or hermaphrodite) and (iii) the female parent status. Six best combinations originated from Boumnyebel and Makenene provenances, characterized by high fruit-setting rate and the fruiting index (˃70% and ˃50% respectively), then by low fruit-dropping rate after fruit set (˂20%) were identified. Although we did not observe increasing in fruit size as compare to breeding in Citrus or Ziziphus species, the process of controlled cross-pollination investigated in this study significantly increased the fruit set. This could help in controlling the early fruit drop which negatively impacts the species’ yield. Thereafter, control-pollinated seedlings (F1) obtained from this study and established as progeny trials will be vulgarized within agro-ecological zones and/ormultiplied vegetatively for clonal and futurecultivars development trials.

Sclerotia production a way ahead to morchella CultivationDr. siddhant
Morchella, the true morels, belonging to Helvellaceae family of class
Ascomycetes, are amongst the most highly priced fungi in the world. Their
artificial production is still a challenge, even though patents for their
cultivation do exist. The tissue of Morchella sp. was transferred aseptically
to Potato Dextrose Agar medium (peeled, sliced and boiled potato, 200 g;
dextrose, 20 g; agar, 20 g L-1) to grow hyphae. The mycelium showed
fastest growth as compared to other edible mushrooms. It covered entire area
of Petri plate (90 mm) within 4-5 days with the growth rate of 18-
22.5mm/day. A unique growth pattern i.e., vertically oriented mycelia were
observed. Brown coloured pigmentation in the culture was also observed
during the study. The basal media for spawn (wheat grains; Glucose, 1%,
CaCO3, 2%; CaSO4, 1.5% and MgSO4, 1%) was aseptically inoculated with
the mushroom culture. The spawn substrate was colonized by mushroom
mycelium in 7-8 days. The sclerotia were formed in unused (old) spawn.
Wheat straw was used as a substrate for mushroom cultivation. It was
supplemented with wheat bran, 20%, Glucose (1%) and MgSO4 (1%). It
showed prolific growth when it was seeded by mushroom spawn using jar
method. Once substrate was fully covered with mushroom mycelium, casing
was applied. Sclerotia were successfully obtained after 14 days of incubation
in our experiment both in the substrate and casing soil but failed to give rise
to fruiting primordial. Further research is going on to domesticate this
species in our country.
Effect of Seed Storage Period in Ambient Condition on Seed Quality of Common ...Premier Publishers
Common bean is used as one of the cheapest source of protein apart from being the major source of cash income in Ethiopia. Its reasonable protein content (22%) made it the poor man's meat securing more than 16.7 million rural people against hidden hunger. Despite the common bean significance contribution to Ethiopian people food and nutrition security and income generation, its production and productivity is low. Among many factors that contribute to the low yield of common bean, low access of seeds of improved varieties and the use of seeds stored for a longer period of time. The length of seeds stored under ambient conditions is a critical aspect of seed quality management. The longer seeds stored under ambient conditions, are the risks of losing the stored beans to storage pests and other seed quality deterioration factors. Therefore, generating information from research is required on effect of seeds stored under ambient conditions on different varieties of common bean. The analysis of variance showed that storage period and variety had significant influence on all seed quality parameters considered except no significant effect on number of hard seeds. No significant differences among varieties were observed on abnormal seedlings, number of hard, fresh ingeminated and dead seeds. However, storage period and variety interacted to influence significantly thousand seed weight, seedling shoot length, nd vigor index I and seedling fresh weight. Due to seeds stored for a long period of time in ambient conditions would make the seed deteriorate and loss its quality during storage. This indicates that, seed deterioration is the result of changes within the seed that decrease the ability to survive.

Weeds are unwanted plant species growing in ordinary environment. In nature there are a total of 8000 weed species out of which 250 are important for agriculture world. The present study was carried out on weed species composition and distribution pattern with special reference to edaphic factor and farming practices in maize crop of District Mardan during the months of August and September, 2014. Quadrates methods were used to assess weed species distribution in relation to edaphic factor and farming practices. Phytosociological attributes such as frequency, relative frequency, density, relative density and Importance Values were measured by placing 9 quadrates (1 × 1 m2) randomly in each field. Initial results showed that the study area has 29 diverse weed species belonging to 27 genera and 15 families distributed in 585 quadrats. Presence and absence data sheet of 29 weed species and 65 fields were analyzed through PC-ORD version 5. Cluster and Two Way Cluster Analyses initiated four different weed communities with significant indicator species and with respect to underlying environmental variables using data attribute plots. Canonical Correspondence Analyses (CCA) of CANOCO software version 4.5 was used to assess the environmental gradients of weed species. It is concluded that among all the edaphic factors the strongest variables were higher concentration of potassium, organic matter and sandy nature of soil. CCA plots of both weed species and sampled fields based on questionnaire data concluded the farming practices such as application of fertilizers, irrigation and chemical spray were the main factors in determination of weed communities.

The Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) is an economically important pest of corn. Finding simple, cheap, and suitable rearing techniques of O. furnacalis is an urgent need to support research for management of this insect. This research aimed to determine the suitability of a read bean and rice branbased artificial diet used for mass rearing of this insect since 2009. The tested artificial diet was compared with the natural diet (sweet corn kernel) and each diet was tested in individual rearing method (one larva in each vial). The criteria used to justify the quality of diet and mass rearing procedure were based on the fitness of O. furnacalis. The degree of fitness was based on life history, growth, and development. In general, the fitness parameteres observed from O. furnacalis reared in the artificial diet at 25.7 ± 1.6 °C with 57.7 ± 3.8% RH, and L12:D12 were similar than those in the natural diet. Therefore, the existing artificial diet and rearing procedure were considered suitable and qualified for O.furnacalis. It is important to periodically check the laboratory colony to ensure that they have similar fitness to those found in the natural population.
Grain Quality of Doubled Haploid Lines in Rice (Oryza sativa L.) Produced by ...Galal Anis, PhD
Genetic devlopment to imrove genotypes with high quality is the most important approach of rice. Thus, anther culture technique is one of straight forward approaches for improvement of rice cultivars with good grain quality. Therefore, this investigation aimed to develop some doubled haploid lines (DH) through anther culture technique and evaluate them along with their five parents including two check varieties for some nutritional characteristics. The results indicated that the three mineral element contents (Zn, Mn and Fe) of rice grain were clearly different among genotypes (DH), which implied that genotypic variations might provide opportunities to select for higher mineral element content. Analysis of variance revealed that the differences among genotypes were significant for all studied traits. Highly significant positive correlations were recognized among the studied characteristics. Accordingly, Rice lines with the high nutritional values will use as donors for this trait in rice breeding programs for exploitation and in hybridization.

The knowledge of gene action and heterosis also helps in identification of superior F1 hybrids in order to use further in future breeding programs. The objective of this study was to estimate the amount of standard heterosis of the pipeline maize hybrids for grain yield and yield related traits. A total of eleven pipeline maize hybrids and two standard checks (BH546 and BH547) were evaluated using randomized complete block design with three replications during the 2015 main cropping season at Northwestern Ethiopia. Mean squares due to genotypes were highly significant (P ≤ 0.01) for most grain yield and yield related traits indicating the existence of genetic variation among the evaluated genotypes. The standard heterosis ranged from -38.72 to 33.65%and the highest heterosis was recorded for CML395/CML202//CML464 cross. The observed highest heterosis for grain yield and related traits indicated the possibility of increasing yield by exploiting heterotic potential of maize genotypes. The information generated by this study could be useful for researchers who need to develop high yielding maize hybrids.

Limited information is available on the effect of seed storage period and plant population on seed quality of the crop. Therefore, this study was conducted at Haramaya University research field to assess the effect of duration of seed storage at ambient condition and plant population on the seed quality of common bean. The treatments were arranged in, factorial combination of three improved varieties (Haramaya, Dursitu and Fadis), three storage periods (9, 33 and 45 months) and three plant populations (320000, 180000 and 115200 ha-1). The seed quality test in the laboratory was conducted to evaluate the seed samples produced from these in a completely randomized design (CRD) with four replications. The seed quality of Haramaya was exceeded by Fadis variety. All seed quality parameters except seedling shoot length, thousand seed weight and proportion of hard seeds during germination had positive and significant correlation with grain yield. Generally, the research findings suggested the importance of using seeds stored for short period of time, optimum plant population and high yielding variety to increase the seed quality of the crop in the study area.
The comparative efficiency of organic and synthetic fertilizers were studied on maize and cowpea, two staple
Nigerian crops. Chemical fertilizer did not support yield as much as poultry manure (PM) or arbuscular mycorrhizal
fungi(AMF), individual or in a combined state. The combination of PM and AMF was the best application expressing
yield in form of shoot productivity. Glomus clarum was a good fertilizing candidate in this study
Bioaccumulation of Lead (Pb) content in three species bivalves in Jakarta Ba...Innspub Net
Environmental pollution by heavy metals has become a serious problem in Jakarta Bay. Mobilization of heavy metals as a result of anthropogenic activities has caused the release of heavy metals into the environment, one of which is Pb. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. In addition heavy metal pollutans in the waters are very stable and tend to be persistent. Recently, bioaccumators is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective using bivalves. These study objectives to analyzed the Pb content of three species of Jakarta Bay bivalves. The results showed that Pb content in the Eastern and Western Season bivalve tissue was significantly lowest in P. viridis (0,166 ± 0,016μg/g dan 0,161 ± 0,155μg/g) compared the Pb concentration in A. antiquata (0,264 ± 0,015μg/g dan 0,247±0,044μg/g), and M. meretrix (0,270 ± 0,016μg/g dan 0,240 ± 0,053μg/g). In this study also showed that the concentration of heavy metal Pb in the bivalve shell of P. viridis was significantly lower than that of two species (A. antiquata and M. meretrix). Pb content in the Eastern Season bivalves did not significantly different from that in the Westerrn Season. This is caused by a weather anomaly where the rainy season occurs almos throughout year of 2020. The Pb content in the bivalves shell was significantly higher than in the body tissues. It is because Pb can replace calcium ions in the formation of animal bones or bivalve shells.
Interaction on the diet and substrate on the growth of Archachatina marginata...Innspub Net
Nine hundred juveniles of Archachatina marginata aged about two weeks, with an average live weight of 2.25 g with an average shell length of 20.12mm were monitored in culture for six (6) months on five types of substrates [S1 (soil collected in a cassava plantation: Manihot sp.), S2 (S1 with 10% oyster shell meal), S3 (S1 with 10% sawdust), S4 (S1 with 5% oyster shell meal and 5% sawdust) and S5 (uncultivated forest soil). Four diets including two industrial (D1 and D 2 of 12% and 16% calcium respectively) and two based on fodder (D3 and D4 based on leaves and fruit of the papaya (Carica papaya) on the one hand and a mixture of papaya leaves and taro (Xanthosoma maffafa) on the other hand, were used. In order to determine the best combinations inducing the best growth performance, 20 combinations were formed at the rate of 45 spat for each combination; three replicas of 15 spat each. This study showed that the combination of diet and livestock substrate influences the growth of Archachatina marginata. Although the best feed is D1 (74.68 g and 7.94cm) and the best substrate is S2 (77.12 g and 7.79cm), the best combinations are D2S3 (69.37 g and 7.47cm), D1S4 (74.68 g and 7.94cm and D4S2 (77.12 g and 7.79cm). The combined effect of the high level of dietary calcium and that of the culture substrate does not promote good growth of snails. This work will help improve the production of African giant snails and provide important data for anyone wishing to engage in the breeding of these animals.

No previous research has assessed the nongenetic factors, especially the nutrition status of MS patients in Arab countries. Hence, this study aims to assess the nutritional status of MS patients among Arab adults. This study is a nationally representative cross-sectional study using a structured, online self-administered, validated quantitative food frequency questionnaire (FFQ) from 13 Arab countries. All data analyses were performed using STATA 16.0 and R for statistical computing version 4.0.4. A total of 813 participants were surveyed, most of the MS participants were female (68.4%), married (58.5%), non-smoker (72.6%) and 53.3% were diagnosed with MS for up to five years. MS participants did not consume the DRI of both the macro and the micronutrients including the energy requirements, except the dietary intake of the sodium which was insignificantly different from the DRI. Results also showed that most participants rarely consumed the main food items including bread, cereals, and most types of meat. While, more than 50% of the participants consumed fruit, vegetables, all types of chicken, fish, fresh soup, rice, and egg up to 3 times per month. On the other hand, milk and milkshake were consumed rarely; while, tea and herbal teas were the most common beverages. Nutrient deficiencies are very common among MS Arab patients. The finding of this study can establish a base for the development of a nutritional program for MS patients in accordance with the recommended DRI.

A germination test was carried out to identify plants that can germinate and survive in polluted soil (with and without ash) collected 2.5km east and 2.5km west, 20km west and 55km west (control) of the BCL Cu/Ni mine smelter in Selebi-Phikwe, Botswana. The experiment was carried out using Phaseolus vulgaris, Moringa oleifera and Moringa stenopetala. Soil acidity and heavy metal stress reduced germination percentage, coefficient rate of germination, root and shoot growth and dry weight, root: shoot, vigour index and tolerance index of all species. Percentage reduction followed the order 2.5km west < 20km west < 2.5km east < 55km west. Phaseolus vulgaris, Moringa oleifera and Moringa stenopetala germinated in all soils. Their ability to germinate in polluted soil indicates tolerance to heavy metal and soil acidity stress and so they have potential for use in phytoremediation of polluted soils around the mine. Phaseolus vulgaris had the highest overall germination performance but there was no significant difference between the Moringas. Application of coal fly ash increased all the germination parameters and so coal fly ash has potential for use in amending polluted soil around the mine for phytoremediation purposes.
Identification and marketing of Marantaceae in the Ndjolé area, in central Ga...Innspub Net
The forests of the Congo Basin cover an area of 200 million hectares, of which just over 10% is in Gabon. In this country, crop products and non-timber forest products (NTFPs) are abundant because of its favourable climate. There is significant biodiversity and great potential for non-timber forest products. This study is interested in the identification and the supply chain of the Marantaceae, one of these NTFPs of plant origin in central Gabon, whose exploitation is national. Through a survey of the main actors in the sector and field visits in the locality of Bifoun, it emerges the existence of three large groups of exploited marantaceae, whose harvest and transport are mainly done by women, in various containers. The storage of this NTFPs does not exceed four days, with the risk of losing its commercial value due to drying out. The uses of this resource are multiple: processing cassava, cooking food, making handicrafts, etc. The income it provides to producers is mainly use towards small family expenses but helps to monetize the rural world. The difficulties inherent in the distance from harvesting points, the low price of the product and the impossibility of long-term storage of the marantaceae leaves constitute a brake on the development of this activity. It would therefore be wise to envisage the domestication of the species listed for a sustainable use of this plant genetic resource.
Ethnobotany of Oyster nut (Telfairia pedata) in Northern Tanzania | JBES 2022Innspub Net
Telfairia pedata (Sims) Hook is an important native climber plant commonly grown in East Africa. It bears nuts which are eaten either raw or cooked and is consumed mostly by expectant mothers, and as cooking oil. The survey was conducted between September 2019 to February 2020 in Sambaa, Meru, and Pare communities of Lushoto, Bumbuli, Arumeru and Same Districts, Northern Tanzania to assess the ethnobotany of T. pedata from a sample of 346 respondents using semi-structured questionnaires. Results indicate that, 21% of respondents used T. pedata for cooking with other staple foods while 18% claimed that the nuts are used by pregnant and lactating mothers for medicinal and breast milk stimulation and nine (9) percent indicated that the nuts are used for cultural and ritual purposes. Despite its importance, the cultivation of T. pedata in the study area is declining and the gap why such decline is experienced needs to be answered in further studies. Secondly, respondents within the 36-50 age groups reported the greatest diversity of uses of T. pedata 51% compared with those aged below 36 years old 21% signifying that the traditional knowledge known by younger aged groups may be declining. Thus, this gap of traditional knowledge between the groups should be addressed in order to improve utilization and conservation of this seriously declining yet important nut in the study area and other places of Tanzania.

This study reports the amphibian’s fauna sampled from the Biodiversity Conservation Area of the hydroelectric dam of Soubré city (southwestern Côte d’Ivoire). This study aims to provide a better understanding of the diversity of amphibians in this relict forest of 200 ha, in order to assess the ecological health of this ecosystem for conservation and sustainable management perspectives. During dry season (from 26 February to 4 March 2018) and rainy season (from 17 to 23 June 2018), we recorded 14 species of anurans grouped into eight genera and six families. The study sites comprise an amphibian fauna consisting mainly of savannah specialists and degraded forest (64.28% of total species richness). Based on the IUCN Red List, all species recorded are of least concern. Also, these species are well distributed in the different regions of Côte d’Ivoire and Africa. Thus, it is necessary to monitor the ecology of the species and to protect subsequently the different habitats of this area.

Dearth of well-articulated information on genetic parameter estimates and diversity of upland rice limits the genetic improvement of rice. This study assessed the genetic parameter estimates and genetic diversity among 40 rice accessions using 26 agro-morphological traits. The trial was conducted in 2020 at the Njala University experimental site using 5 × 8 triple lattice design. The agro-morphological traits were analyzed using various multivariate and genetic parameter estimate techniques. Classification based on qualitative and quantitative traits grouped the germplasm into ten and five distinct clusters, respectively. Genotypes Buttercup-ABC, Buttercup-RARC, Jewulay, NERICA L4, Ndomawai, Sewulie and Painipainie produced earliest days to heading (81.8–97.2 days) and maturity (111.2 – 120.7 days). Genotypes Jasmine (3.036 t.ha-1), Rok 34 (3.238 t.ha-1) and Parmoi (2.663 t.ha-1) exhibited the highest grain yields. Principal component analysis (PCA) of qualitative traits exhibited four principal components (PCs) with eigenvalues > 1.0 and cumulative variation of 68.04%, whilst the PCA of quantitative traits had five PCs accounting for 81.73% of the total genetic variation. The findings indicate the presence of enough variability that could be exploited for the genetic improvement of rice varieties and the studied traits can be used for selection. Leaf blade length and width, culm diameter at basal internode, culm length, days to 50% heading, flag leaf girth, panicle number per plant, grain yield, and 100 grain weight had high heritability and genetic advance indicating the presence of additive gene action. Findings are relevant for conservation, management, short term recommendation for release and genetic improvement of rice.

Urbanization is increasing rapidly in all parts of the world to accommodate the increasing human population but it is having a drastic effect on native flora and fauna. The present study was carried out across a three stage urbanization gradient in and around the city of Bilaspur, Chhattisgarh. Observations were made from September 2019 to February 2021 at the selected three sites during COVID 19 pandemic. Point count method was used for bird surveys and Sound pressure (Noise) measurements were made across the three selected sites. The Avian diversity was measured by total species richness, Fisher’s alpha diversity index and Shannon-Wiener diversity index. The Urban centre recorded the highest sound pressure and lowest Avian species richness but as we moved away from the urban centre the noise levels reduced and the avain species richness increased towards the rural areas. This is mainly due to many avian species avoiding urban areas because of increasing noise levels. We also found that the urban bird community is dominated by a few species whereas the rural bird community was much more diverse.

The present study demonstrates the ability of GIS and RS in capturing the spatial temporal data. The changing climatic conditions in the country effects the agriculture. The impacts of climate change are not only restricted to the agricultural productivity of the Pakistan but changing climate also impose destructive impacts on the Land use change practices. Three districts of Punjab i.e. Attock, Multan and Gujrat were selected for analysis of climatic effect on wheat production. The time span that is used for analyzing the change in these areas was from 1999-2014. Climatic changes are not always negative ones but sometimes climatic changes are favoring the increased agricultural production. As the change in temperature and rainfall pattern affects the crop conditions, which changes the net production. It is concluded that for real time prediction of crop yield satellite remote sensing could be used for timely management of food crisis in Pakistan as well as in the world.

Extreme weather events are anticipated to increase the existing challenges and generate new combination of vulnerabilities, especially in developing countries. The agricultural sector is the most vulnerable due to overreliance on unpredictable rainfall. This study examined the impact of extreme weather events on urban crop production and the adaptation strategies applied by the farmers. Secondary data were collected through a literature survey and primary data were collected using structured interviews, observations and focus group discussions. A total of 108 crop farmers were interviewed in two wards of Kinondoni District. The Statistical Package for Social Sciences (SPSS) version 20 was used to analyze the data and Pearson Chi-square was used to test the statistical significance between variables. The study observed that, farmers perceived extreme weather events including floods (39%), extreme temperatures (36%), and drought (25%). These extreme weather events affected negatively crop production leading damaging of crops and low yields (38%), outbreak of crop pests and disease (38%), drying of water sources (20%), and loss of soil fertility (4%). Crop farmers used various adaptation strategies such as crop diversification (28%), the use of pesticides (23%), changing of cropping patterns and planting calendar (16%), irrigation practices (18%) and replanting (10%). The study recommends for adoption of new farming systems such as vertical farming systems for better output with the use of limited water and land resources.

Catchment degradation has continued to occur globally albeit the presence of Community Forest Associations (CFA) and Water Resource Users Associations (WRUA). Similarly, Kilungu catchment area in Kenya is under the management of the Kenze (CFA) and upper Kaiti (WRUA). This paper examined Kenze CFA and Upper Kaiti WRUA activities by exploring their effectiveness in discharging their statutory functions. This was achieved by carrying out, an exploratory descriptive survey. Data was collected through questionnaires, focus group discussions, 10 key informants’ interviews and direct observations. Descriptive analysis was used. Information was presented in fig.s, tables and percentages. Results showed that upper Kaiti WRUA as more effective in catchment management at moderately (31%) and highly at (37%) as compared to CFA moderately (29%) and highly (5%). In terms of discharging of their statutory functions, Upper Kaiti WRUA was better at a rating of 27% (good) and 23% (very good) as compared to Kenze CFA which was rated at 3% (good) and 6% (very good). This study results implied that Upper Kaiti WRUA was more effective in all aspects of ensuring catchment management as opposed to CFA. In conclusion, a strategy of seizing the opportunities presented by the CFA of being empowered to perform all its activities as required by law with emphasis on the timely preparation and implementation of management plans and WRUA’s continuous improvement should be prioritized. The study recommends new initiatives that improve on the CFA and WRUA activities in order to effectively discharge on their statutory functions.

Liming leads to high bean and maize yield on a strongly acid tea soil | IJAAR...Innspub Net
Acid soils are very common in tea zones. These soils have a pH below 5.0. Below this pH, not only do the soils exhibit toxicity of aluminum and manganese but are deficient of calcium, magnesium, phosphorus and molybdenum, hence becoming chemically infertile. Liming is one cheap way of reclaiming these soils. The staple food crops in these tea soils are maize and beans. However the effect of different liming levels on bean (Phaseolus vulgaris L.) and maize (Zea maiys, L.) yield on acid tea-growing ando-humic Nitisol had not before been investigated. A study was therefore conducted to determine the crop response to liming and the appropriate liming level for maize and bean crops in a tea zone soils. The experiment was carried out in Embu County, Kavutiri and Kianjokoma areas, Agro-Ecological Zone (AEZ) UM1. A randomized complete block design with four replications of each lime treatment was used at each site. Lime at rates of 0 (L0), 2.4 (L1), 6 (L2), 8 (L3) t/ha was broadcasted on to 4m x 4m plots and mixed into 0-15cm of soil. There was a significant response to liming for both maize and beans. The maximum maize and beans yield was attained at around liming level L2 (pH 5.5). Above this pH, yields started to decline. The study clearly shows the benefits of soil liming on strongly acid tea soils and also the importance of accurate lime applications.

The ethanol, ethyl acetate, and hexane extracts of the freshwater clam (Corbicula fluminea) were studied for the total phenolics and total flavonoids. Total phenolics and total flavonoids of the extracts were evaluated using Folin-Ciocalteau and Aluminum chloride colorimetric methods respectively. The findings showed that the total phenolics of the ethanol extract (1.67±0.28mg GAE/g of dried sample) were substantially higher than the total phenolics obtained from the ethyl acetate (0.70±0.00mg GAE/g) and hexane extracts (0.56±0.23mg GAE/g). While the total flavonoids in the ethyl acetate extract displayed a slightly higher total flavonoid (43.84±0.92mg QE/g of dried sample) relative to ethanol (30.41±1.34mg QE/g of dried sample) and hexane extracts (20.28±0.00mg QE/g of dried sample). Using ethanol, the highest yield for extraction was obtained. Ethanol is the best solvent among the three – ethanol, ethyl acetate, and hexane in terms of extraction yield and total phenolics. In addition, it can be inferred that the presence of significant amounts of phenolics and flavonoids suggests that freshwater clam is a promising source of antioxidants that provides nourishing proteins and oxidative stress remedies
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

insecticidal applications. The present study was designed to investigate the effect of neem application in
controlling Pod borer on six different genotypic varieties (AZ-CM2, AZ-CM4, AZ-CM6, AZ-CM10, AZ-CM12 and
Noor-91). The experiment was designed in a Split-Plot Design with three replicates. Different agronomic traits
were recorded such as plant population, plant height, percentage flowering, physical maturity, number of pod
per plant, infestation of pod borer and yield of chickpea. The results showed that plants treated with neem have
high population (maximum in Noor-91 with 16.8 plants/m2 and minimum in AZ-CM12 with 2.9 plants/m2, plant
height (46.7 cm in AZ-CM4 and 34.7cm in Noor-91), flowering (AZ-CM10 gave 50% flowers after 100.3 days),
physical maturity (AZ-CM4 took maximum time (139.7 days) to attain 90% physical maturity while AZ-CM2 and
AZ-CM4 took only 136.0 days to attain 90% physical maturity), average number of pods (Noor 91 has higher 19.4
and AZ-CM2 has lowest 12.1). Infestation of pod borer and % damage was found lower in neem sprayed plant.
Overall highest yield was observed in plants treated with neem as compared to control and genotype dependent.
It is concluded from the results that neem application has a significant effect in controlling pod borer and this
effect varies genotype to genotype. Noor-91 was found to be more resistant towards pod borer.

Introduction
Chickpea (Cicer arietinum L.) is ranking the second
main legume food obtained by resource-poor cultivars
in the arid and semi-arid regions of the world. The
genus Cicer was originated in South-Eastern Turkey
and reached to other regions of world. It is adapted to
comparatively cooler climates. Globally, cultivation of
chickpea in 45 countries of the world including all the
continents and occupied 12.14 million hectares
cultivated area with the production, of 11.3million
tones (Kumar and Abbo, 2001).
The largest area of adaptation where much
production occurs is the Indian sub-continent
Chickpeas are categorized into two distinct types: the
small-seeded ‘desi’ with brown-coloured seed coat
accounts 90% and the large-seeded cream or beige-
coloured ‘kabuli’ accounts up to 10%. Kabuli
chickpeas are cultivated mostly in Pakistan, Turkey,
Ethiopia, Syria, Spain, Canada, the United States,
Mexico and Portugal (Krishnamurthy et al., 2013).
Chickpea seeds are very nutritious, comprising ~25-
29% protein (Hulse, 1989) while 4-10% fat, 52-71%
carbohydrate, and 10-23% fiber, minerals and
vitamins (Jukanti et al., 2012). Additionally, the seed
protein containing necessary amino acids such as
lysine, methionine, threonine, valine, isolucine and
leucine to provide necessary components of human
diet which are useful for maintains of health and fix
atmospheric nitrogen and improve the soil fertility. It
is a crop with self-pollination having a basic
chromosome number 8 and a 739-Mb genome size
(Varshney et al., 2014).
Due to rapid increase in population with the passage
of time, demands for food grains and usual
proliferation efforts require to be supplemented by
genomics-assisted breeding (GAB) (Varshney et al.,
2013). Agricultural practice improved genotypic traits
which ensure survival of chick pea has been
functional in plant reproduction which incorporate
reserve remobilization (Blum, 2005). It is estimated
from throughout about 90% total yield of chick pea is
obtained from rain-fed areas including arid and semi-
arid regions (Kumar et al., 2001).
In drier and warmer regions of semi-arid tropics of
East Africa, Chickpea is considered as a chief protein
source for the population in arid and semi-arid world
(Kimurto et al., 2013).
Chickpea is cultivated in 45 countries of the world
and covers an area of 11 m ha with yield of 9 million
tones. Kabuli chickpea is generally cultivated in
temperate and subtropical regions and it covers
nearly 10% of the total production of the world.
Chickpea was considered to be an orphan legume for
only a few years ago due to insufficient genomic
assets for implementing GAB. Yet, the accessibility of
chickpea genome sequence information (Varshney et
al., 2013) and extensive genomic resources (Varshney
et al., 2013) have changed the crop into a resource
rich crop like any other main crop species.
H. armigera (Hubner) (Lepidoptera: Noctuidae) which
is Chickpea pod borer (CPB), the main notorious pest of
chickpea which destroy the crop on large scale. It is one
of the most important limiting factors for its production
many regions of the world (Sharma et al., 2005). H.
armigera also causes productivity losses in many
vegetables and crops such as cotton, okra, tomato. About
50-60 % damage was recorded in chickpea due to H.
armigera (Verma et al., 2015).
Larvae of H. armigera causes serious damage to
chickpea crop during the fruiting stage, originally by
appearing on new leaves then shifting to flowers,
young shoots and as a final point entering the pods. A
single larva can damage many pods before reaching
the pupal stage. It is another factor that H. armigera
has developed resistance against conventional
insecticides due to overuse (Kranthi et al., 2002).
Large genetic variation for the different traits has
been reported and the breeder can make use of it to
evade the damage caused by the H. armigera in crop
of chickpea. Therefore, the breeding target should be
identified, characterized and develop genetic
mechanism that confers durable resistance to H.
armigera (Dua et al., 2001).
3. 112 Hussain et al.
Int. J. Biosci. 2016
Improvement of farmers with resistance to H.
armigera might provide a valuable approach in
integrated pest management (IPM) to reduce the
productivity losses of chickpea (Sharma et al., 2005).
The use of pheromone trap + BT + Ha NPV effectively
control pod borer (H. armigera) in chickpea (Kumari
et al., 2015). Studies have been conducted by a
number of researchers on screening of chickpea
varieties for resistance and tolerance against H.
armigera (Rashid et al., 2003; Shafique et al., 2009;
Ali et al., 2016).The aim of the present study was to
control the damage caused by H. armigeraon
important crop chickpea by applying integrated
management to improve the yield of chickpea.
Materials and methods
Site description
The control experiment was conducted at the research
farm, University of Agriculture Faisalabad, while
repeated field experiment and survey was conducted
in Thal Desert in Punjab, Pakistan. Thal desert is
located in District Layyah of Province Punjab,
Pakistan has 305.71 Km length and 112.63 Km
breadth near Jhelum and Indus river sites and goes
up to North in Potohar Plateau.
Climate of Thal is extremely hot during summer
season and temperature rises up to 51.6°C
temperature of arid region and has brown color soil.
The study area is approximately barren and consists
of sandy dunes and forest. Average rainfall is 128 mm
to 178 mm but sometime there is too much less
rainfall and ranges from 2 to 4 years. Therefore, there
is scanty of water in Thal at the depth of 25-90m.
Study area is actually a Rakh under control of Forest
Department.
Preparation of neem extract
Neem Seed Kernel Extract (NSKE 5%), 5 kg of Neem
Seed Kernel (well dried) was ground into powder
form and soaked overnight in 10 liters of water. Next
morning, the solution was stirred with a wooden
plank till it became milky white and was, filtered
through double layer of muslin cloth. The volume
now made up to 100 liters. Thus, the 5% concentrated
solution of NSKE was ready to be sprayed in the fields
(Verma et al., 2015).
Field Survey
A field survey was conducted of Thal. The collection
was mainly done to check the presence of H.
armigera on different hosts and how it shifts from
one host to other hosts (Phenology).
Crops like Peas, Cauliflower, Brinjal, Cabbage and
Chickpea. Weeds like Bathu, Senjietc were also been
observed there but no H. armigera was found there.
Upon digging of soil diapa using pupae of H.
armigera were observed and collected for the
laboratory studies but no active stage of H. armigera
was observed.
From this survey, it can be inferred that the active
stages of H. armigera are absent during that time and
the pupae of H. armigera goes into diapauses due to
low temperature and coldness.
Agronomic Practices
Six genotypes of chickpea viz. Noor-91, AZ-CM-2, AZ-
CM-4, AZ-CM-6, AZ-CM-10, AZ-CM-12 were sown
with hand drill. Land preparation was done by two
cultivations followed by planking.1.5 bags of MAP
(mono-ammonium phosphate) and 1 bag of Urea was
applied as fertilizer. Irrigation was applied 5 days
before crop sowing.
The varieties were sown in a Split-plot Design with
three replications. In one plot the Neem application
would be done and in other plot there would be no
Neem application. The plot size of each replication
was maintained at 20 m x 24.0m (Hossain et al.,
2009). Two light traps and 4 pheromone traps were
installed near the field to trap H. armigera (Hübner)
and other Noctuidae pests.
Estimation of H. armigera Damage
Crop pest scouting was done regularly after 3-4 days
and 10 plants were examined thoroughly from each
plot to check the damage per plant by recording
population per m2, plant height (cm), flowering
(percentage), average number of pods, physical
maturity (percentage), infestation of pod borer
(percentage) and percentage damage.

Maximum height was obtained by AZ-CM4 (46.7 cm)
followed by AZ-CM12 which is 44.9 cm. The lowest
height was attained by Noor-91 (34.7 cm). There was
no significant difference was observed of neem
application on the heights of chickpea cultivars (Fig.
8). Earliest 50 percent flowering was observed in AZ-
CM10. In AZ-CM 10 the 50 percent flowering was
observed in 100.3 days after sowing of crop.
The differences among the days to 50 percent
flowering were non-significant among the cultivars
(Fig. 9). The comparison of 90 percent physical
maturity of different chickpea cultivars in neem
treated and untreated plots.
The differences among the cultivars of chickpea in
neem treated and untreated plots were found non-
significant. AZ-CM4 took maximum time (139.7 days)
to attain 90 percent physical maturity, while AZ-CM2
and AZ-CM4 took only 136.0 days to attain 90
percent physical maturity.
There was no significant difference was observed of
neem application on physical maturity (Fig. 10).
Highest average number of pods were found on Noor-
91 (19.4) followed by AZ-CM12 (18.4) and AZ-CM6
(14.7), also indicating that there are significant
difference in pod number in neem treated and
untreated plots (Fig. 11).
Highest population per plant were observed in AZ-
CM12 (3.0 larva) followed by AZ-CM2 (2.2 larva) and
AZ-CM 4 (2.1 larva). There was a significant impact of
neem application in reducing the population of pod
borer (Fig. 12). Most susceptible variety against the
infestation of pod borer was Noor-91 (34.3 percent).
After Noor-91 the highest infestation was observed in
AZ-CM6 (29.1 percent) followed by AZ-CM12 (26.1
percent). The lowest infestation was observed in the
AZ-CM10 (19.0 percent).
There was a significant reduction of infestation in
Neem implicated plots (Fig. 13). Highest yield was
obtained from Noor-91 at the rate of 1115.4 kg per ha.
AZ-CM12 showed good potential and had an
estimated yield of 1073.6 kg per ha.
The lowest yield was obtained in AZ-CM2 654.0 kg
per ha. There was a significant decrease in yield in all
the varieties were Neem was not applied (Fig. 14).
This study will be continuing around the year to
monitor their population and behavior.

Discussion
Chickpea, C. arietinum L. is an important pulse crop
in Pakistan, it is mostly grown in rainfed and irrigated
areas of the Punjab and covers an area of 1.11 m ha
with a grain production of 475 thousand tons per
annum (Anonymous et al., 2008). Pod borer, H.
armigera (Hub.) is a key pest and a prominent
limiting factor in the successful cultivation of
chickpea (Lateef et al., 1985). The financial loss due
to H. armigera harm was expected up to 2030
million rupees per annum in chickpea (Lal et al.,
1985). Controlling type of harmful pest of chickpea
has proved to be very intricate; mainly in the most
recent decade as insecticide resistance has increased
(Armes et al., 1993).
The application of neem extract increased the
emergence of chickpea plants as compared to control.
Among the genotypes, Noor-91 has maximum
population with16.8 plants/m2. Similarly height of
the plant was also found higher in neem treated
plants. Preliminary outcome propose that there are
high levels of preservative genetic variation for the
capability to nourish on the moderately resistant
chickpea being maintained in the population as
presented by (Fitt and Cotter, 2005). Though the
modes of resistance or vulnerability might be
genotype based. Different nutritive values of host
plants may also manipulate the rate of growth of H.
armigera larvae, thus affecting the population
dynamics of this pest.
The given research exactly matches with the findings
of (Hemati, Naseri, Ganbalani, Dastjerdi, and
Golizadeh, 2012). Earliest 50% flowering was
observed in Noor-91 after 102.3 days comparison to
other genotypes. The results were in agreement with
consequences obtained in 28 diallel trials conducted
at ICRISAT representing that days to 50% flowering
was mostly under additive inheritance and highly
predictable (Singh et al. 1992a). In neem applied
plant, earliest 90% physical maturity was seen and
among the varieties, AZ-CM2 90% matured after
136.3 days. Our results relates with the findings of
Yelshetty et al. (1996) who compared the percentage
pod damage at maturity of each trial with that of the
control and transformed to pest susceptibility rating
(PSR) on a scale of 1 to 9). The lower PSR values
represented the lower level of pod borer attack on
genotypes and better tolerance to pod borer. There
was a significant impact of neem application in
reducing the population of pod borer. On an average,
30 to 40 percent pods were found to be damaged by
pod borer with an average of 400 kg/ha grain loss. In
favorable condition, pod damage goes up-to 90-95
percent.
Earlier reports representing the significance of
variances for number of pods per plant relates with
the investigations made (Singh et al. (1992b) and
Yoshida and Shanower (2000) who recommended
that a growth inhibitor or anti-feadent material or
both existed in the resistant genotypes.
7. 116 Hussain et al.
Int. J. Biosci. 2016
The larval survival, larval weight, pupal weights,
pupation and adult appearance were constantly lower
in the resistant genotypes than the vulnerable ones
and the standard diet.
Overall yield of chickpea was found to be higher in neem
treated plants as compared to control. There was a
significant decrease in yield in all the varieties were
neem was not applied. In spite of the pest hit in the
season, there was an improvement in production when
genotypes with resistance modes were planted. The
seasonal discrepancies in yield losses pragmatic may
also be credited to pest prevalence and genetic
composition of arrays such type of attempts agreed with
the results of Hossain(2009) and Rajput et al., 2003).
Orientation and settling, feeding, metabolism of
ingested food, growth, survival, fecundity, oviposition
and hatching of eggs are the most important response
categories of insects that determine their successful
invasion and utilization of host plants [Saxena, 1969].
The establishment of insects and their consequential
damage on the host plant may be reduced or affected
by disruption of one or more of these important
responses. Dried neem leaves and seed cakes were used
for long time in India to protect crops from pests.
Previous studies reported natural plant products which
possess multitudes of effects such as repellence,
feeding deterrence, growth and development inhibitory
and other effects have some potential for the
management of pests (Klocke et al., 1989).
Nardo et al. (1997) reported that the substance in
aqueous extracts of leaves and neem seeds inhibit the
development of larvae, egg fertility and exerts repellent
or toxic effect on B. tabaci. According to Viňuela et al.
(2003), azadirachtin has effects similar to that of
diflubenzuron (DIMILIN 25 WP, Agr Evo, Valencia,
Spain) with similar actions in juvenile hormone
blocking insect metamorphosis. It inhibits the growth
that affects spawning (Bruce et al., 2004) and molting
and larval development (Islam et al., 2007).
Grain productivity was mainly under the control of
dominant gene action which have a tendency to
enhance or reduce grain production are more or less
present in equal frequency in parents of the early
maturity group while in medium and late maturity
groups they were relatively in imbalanced frequency
(Gowda, Ramesh, Chandra, and Upadhyaya, 2005).
Preservative gene action governed the inheritance of
resistance to H. armigera whereas non-additive type
of gene action was main for inheritance of antibiosis
constituent of resistance (larval survival and larval
weight) and grain yield (Narayanamma et al., 2013).
The presented consequences were in agreement with
(Kumar et al., 2001) who reported that non-additive
genetic effects are of chief import for yield. Moreover
plant resistance to pests is an economically and
ecologically favorite option to other pest management
strategies. Host plant resistance is simple, expedient
and contemptible and generally works well in
arrangement with new forms of pest management
while it can have severe implications for the
effectiveness of some alternative pest management
strategies.
In some cases, serious inappropriateness does occur
between natural plant resistance and other pest
management approaches, consequently there is a
great need to realize completely the mechanisms
concerned in resistance to guarantee that antagonistic
effects can be avoided (Stevenson et al., 2005).
Farmers mainly rely on insecticides for the
management of H. armigera.
The chickpea genotypes identified as constant in
resistance to H. armigera harm can be used in
further breeding programs to develop resistant
varieties. Diallel analysis revealed the gene action for
H. armigera resistance and suitable breeding
technique can be preferred to develop resistant
varieties. The main point of view of given research
was to assess the relative importance of various
Genomic traits that might add to yield stability for
further breeding efforts in chickpea.
8. 117 Hussain et al.
Int. J. Biosci. 2016
The results support to conclude safely that the pod
infestation, larval population and grain yield could be
used as selection criteria of a resistant genotype as the
fundamental part of management program against H.
armigera.
Conclusion
Several studies have been conducted and valuable
information has been generated for a targeted
chickpea breeding program to improve the
productivity. Very little effort had been made toward
identification of other potentially important traits
apart from the root traits yield improvements in
chickpea. Such type of researches mainly focused on a
single or a few target genomic traits from the last
decade. Consequently such genotypes have a valuable
resource of borer resistance that could be utilized
either as varieties or by using them in hybridization to
develop high yielding and pod borer resistant variety
as an element of integrated pest management
strategy. To attain this, training in modern plant
breeding skills and development integrated breeding
strategies and sharing of information and capability
among mutual associates, particularly in developing
countries with inadequate infrastructure and human
resources are the necessitate of the age.
