However, the rate of conversion to organic production is much slower than in other countries and the tea farmers who work hard all-around a year have not got proper market share due to several reasons. The study was conducted in Suryodaya municipality, Sakejung, Jasbire, Maipokhari, and Sandakpur area of the Ilam district by purposively and randomly selecting 160 tea farmers for questionnaire survey to determine the socio-economic and institutional factors that play a significant role in organic cultivation practice and selection of effective marketing channels. The data were collected from the interview with farmers, direct observation, focus group discussions and key informant interviews using pre-tested semi-structured questionnaires. The average gross margin per kilogram green leaf was NRs. 17.16 for organic and NRs. 13.15 for conventionally produced ones. The decision of farmers to practice organic orthodox tea production and selection of efficient marketing channel in the study areas was estimated through the Logit model. The involvement of farmers in cooperative and marketing channels followed for the marketing of green leaves and farming years significantly affected the organic cultivation of orthodox tea. The study revealed that the marketing channel; producers–cooperatives–processors–retailers– consumers was found to be the most efficient. The ethnicity, farming experience, and organic production of tea significantly affected the selection of an efficient marketing channel by orthodox tea farmers.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75963955","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}

This pest was formally reported for the first in January 2016 in Africa and in May 2018 in India. On 9 May 2019, this pest was first noticed in Nawalpur Nepal. 20-35% losses have been reported in maize crops. Since the outbreak of this pest from Africa, entomologists are working for their strategic management. This review aims to compile the fall armyworm (FAW) management works carried in the world and discuss their relevancy in Nepalese context. Of the various practices, chemical pesticides are one of the most commonly used tools followed by habitat management and other cultural practices. Insect pheromones are used for pest monitoring, and thereby to improve pest management decisions. Trap cropping, cover cropping, intercropping, maintaining floral diversity are some examples of habitat pest manipulation. Push-pull strategy uses Napier crop as a ‘Pull’ component and Desmodium crop as a ‘Push’ crop. These agro-ecological strategies change the behavior of FAW and able to trap or manage them in a certain area or certain crop, where pest can be managed manually or using other non-insecticidal strategies. This review work will be useful for the academicians, extension workers and plant protectionist to design a sustainable FAW management protocol.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90099785","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}

Further in some places farmers try to store in normal room and cellar storage facility with considerable amount of post-harvest loss. Recently cool bot storage facility has been introduced to storage horticulture commodities. Thus an experiment was set to study the effect of various storage structure on shelf life of sweet orange at National Citrus Research Program, Dhankuta, Nepal. Four types of storage facilities (zero energy, cellar, cool bot and normal room) were used to store sweet orange fruit over 90 days. Freshly picked Dhankuta Local sweet orange fruit with small pedicel intact were used for this study in RCB design with four treatments replicated four times. Physiological loss in weight (PLW), fruit rot percent, juice recovery percent, TSS and TA were recorded at weekly interval. The result revealed that there was no significant difference in chemical quality parameters (TSS and TA) due to storage method. However, juice recovery and PLW was better in cool bot and cellar stored fruit with ≤15% fruit rot when waxed fruit were stored at 10-12°C with more than 85% RH.

Two factors included were: three rice cultivars; Arise-6444, Sarju-52, and Sukkha-3, and three transplanting dates; 19th June, 29th June, and 9th July. Phenological observation and yield attributing characters were recorded and statistical analysis was done. Cultivars under different transplanting dates showed significant variation in yield, yield attributes, and agro-climatic indices, individually and in interaction. Variety Arise-6444 attained early booting, panicle initiation, heading and flowering followed by Sukkha-3 and Sarju-52, respectively. Cultivar Arise-6444 showed the highest panicle weight (4.84g), effective tillers m-2 (242), grains panicle-1 (201) and grain yield (9213 kg ha-1). Early transplanting brought the phenological stages late as compared to mid and late transplanting. Cumulative GDD and PTI were significantly higher in Sarju-52 being 2066 and 15.90, respectively, whereas Arise-6444 showed the highest HUE (4.702). Irrespective of transplanting dates, early transplanting exhibited the highest GDD (2150.76) and PTI (16.36). Early transplanting of Sarju-52 showed the highest GDD (2211) while the highest PTI (16.59) was recorded in early transplanting of Arise-6444.

Among the examinees, 12.98%, 38.48%, 34.0%, and 8.28% secured distinction, first, second, and pass division, respectively and 94% got success with their average of 25.48 score.

Fairly superior grading performance was analyzed for the constituent campus examinees over private to community campuses. Significant variations in grading analyzed due to gender, inter-campus and affiliation-type; however, no ethnicity effect was assessed in overall grading.
