The experiment was laid out in two factorial Split plot design and replicated three times. Five varieties of okra viz. Parvati, Arka Anamika, NOH-15, Super Green and Julie were used and five treatments viz. Jholmol (1:5), Azadiracthin (5ml/L), Imidacloprid (2ml/L), cow milk (100ml/L) and control (distilled water) were used as foliar spray on plants. The chlorophyll content of the leaves was higher in Julie followed by Arka Anamika. The white fly count was found to be reduced after the application of treatments in the succeeding date in almost all varieties. The efficiency of the management practices was found to be significant with Super Green and Julie varieties with least Percent Disease Incidence(PDI) value and in par with each other. Imidacloprid and Azadiractin had the leastPDI value and the combination of Super Green variety with Imidacloprid, Super Green with Jholmol, Super Green with cow milk, Julie with Imidacloprid, NOH-15 with Imidacloprid were found resistant. Similarly, the highest yield was obtained in Julie with Imidaclropid combination. However, due to the maximum waiting period of this chemical as well as its negative impact on human and plant health, Julie with Azadirachtin combination can be suggested to farmers to have eco-friendly management of Okra yellow vein mosaic virus.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86796732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two coccinellid species, i.e. Coccinella septumpunctata Linn. and Adonia variegate (Goeze) were given four aphid species viz; Myzus persicae (Sulzer), Lipaphis erysimi (Kaltenbach), Aphis craccivora (Koch) and Brevicorynae brassicae Linn. separately to compare the efficacy of two beetle species as effective bio-control agent. Predatory activity of C. septumpunctata was the highest on L. erysimi(feeding 183 aphids) and the lowest on A. craccivora (feeding on 126 aphids), while, that of A. variegate (Goeze) was the highest on L. erysimi (feeding 155.4 aphids) and the lowest on B. brassicae (feeding 112 aphids) during their larval stages. Fourth instar individual larval weight of C. septumpunctata was recorded the highest (26.82 mg) when fed on A. craccivora and the lowest (13.9 mg) when fed on B. brassicae, while the 4th instar larval weight of A. variegate was only 12.82 mg and 11.34mg when fed on same aphid species. Pupal and adult weight was also recorded the highest for C. septumpunctata as compared to A. variegata. Similar result was obtained for weights of adult when larvae fed on A. craccivora. The weight of female was observed relatively higher than that of male from this study for both beetle species. There was a positive correlation between predation and weight gained by larvae with respect to all aphid species. From this study, it can be concluded that C. septumpunctata seems better promising species of predators of aphids, especially beneficial in biological control of aphid species.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86125167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Result revealed that there is severe infestation of maize weevil and green fungus in stored maize. 97.5% of stored samples had incidence of Aspergillus, whereas 96.7 % samples had maize weevils. 15.7% of the farmers apply sun drying and removal of the A. falvus infested seed while remaining 84.3% of the farmers use no any measure of control. Results from Chi- Square test indicated significant relation (χ2 = 122.10, P<0.01) between incidence of weevil infestation and occurrence of green fungus in the study area. The Phi coefficient value (1.00) shows the perfect relationship exist between weevil and green fungus occurrence in the study areas. The overall annual damage by the A. flavus was 6.39%. Therefore, it can be said that maize weevil is the major insect while A. flavus is major pathogen of maize grains at storage. The relationship between the occurrences of both pests was highly significant which indicated the positive relationship, i.e. the weevil plays an essential role in growth and spread of fungus.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89284465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that least number of plants were damaged in plots applied with treatments Lara-909, subsequently followed by Spinosad while more plants were damaged successively in control and M. anisopliae.

The experimental site consisted three areas: Pakadi VDC ward no.-3, Barrohiya of Kapilvastu district; Ramgram municipality ward no.-1, Sanda of Nawalparasi district and Tukuligadh VDC ward no.-1, Rehara of Rupandehi district. The indigenous nutrients supplying capacity of the soil was determined by establishing omission plots for wheat cultivation with six treatments each of 50 m2 and 4 farmers from each site was taken assuming one farmer as one replication. Among the six treatments, -N, -P, -K, –Zn and –B were set to estimate the inherent N, P, K, Zn and B supplying capacity of soil respectively. From two years of experiment, it has been clear that inherent N and K supplying capacity of soil in selected areas is very low. The highest grain yield of 3.33 t/ha and 2.75 t/ha was measured from fully fertilized plots in 2013/14 and 2014/15 respectively and the lowest grain yield of wheat was obtained from nitrogen missing plots in both years (1.74 t/ha and 1.51 ton/ha) followed by potassium missing plots (1.74t/ha). Farmers manage their field in a different way, so large variation was seen even in small area. Nitrogen was found to be most limiting nutrient for wheat growth followed by potassium and phosphorous in all sites. Therefore, use of optimum dose of nitrogen, phosphorus and potassium should be used for efficient nutrient uptake which ultimately increases wheat productivity.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84151595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
