Using a pre-tested questionnaire, primary data and information were collected from 300 lentil grain producing farmers, categorized by local seed users, improved seed users, and 100 seed producing farmers in Kailali, Dang, and Siraha districts. The study revealed that the B:C ratio in lentil seed production was higher (1.59) than in lentil grain production (1.41). The benefit in both grain and seed production realized by farmers was mainly due to increased prices rather than production. Return to scale was found to be increasing (1.016) in lentil grain production using local seed, but it was decreasing at a rate in lentil grain production using improved seed (0.854) and in lentil seed production (0.822). Analysis on resource use efficiency revealed that labor input is excessively overused, reflecting the Marginal Value Product of less than unity in lentil production. To get the maximum profit from lentil grain production using improved seed, input use in land preparation, threshing, and post-harvest should be increased while decreasing the amount of other inputs.","PeriodicalId":31348,"journal":{"name":"Journal of Nepal Agricultural Research Council","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46364561","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}

A study was done to investigate the performance of indigenous buffalo found in high-hill of the western districts of Nepal. Further, effect of genetic and non-genetic factors on productive and reproductive performance of indigenous buffalo was accessed. This study was done in four districts: Myagdi, Baglung, Parbat and Kaski for 2 consecutive years from 2016 to 2017. A semi-structured and questionnaire survey format was prepared and was filled with verbal answers from 142 farmers on a different aspect of buffalo farming. Further, recording formats were distributed to enumerators for the recording of different information that cannot be collected from the survey. Total of 201 indigenous buffaloes (132 Lime and 69 Parkote) and minimum of 25 buffaloes in each site were measured for determining productive and reproductive performance. Further, 65 collected milk samples were subjected to Animal Nutrition Laboratory of DoAR, Lumle for determination of milk composition. Results of the findings revealed that there was a high variation in productive and reproductive performance of indigenous buffalo. Lactation milk yield of Lime buffalo was observed slightly higher (1180.90 ± 27.94 L) than Parkote buffalo (1170.56 ± 42.29 L) but was non-significant (pg0.05). Lactation yield of indigenous buffalo in Ramja, Parbat (1254.73±38.43 L) was observed significantly higher (Pl0.002) than other research locations. Genetic evaluation of indigenous buffaloes and selection of better performers help in increasing productivity and lead to conservation by competitive advantage of indigenous buffaloes. Non-genetic factors play an important role in the productive and reproductive performance of indigenous buffalo and need to account for these effects to select buffalo for its genetic merit.","PeriodicalId":31348,"journal":{"name":"Journal of Nepal Agricultural Research Council","volume":"7 1","pages":"83-91"},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43674311","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}

To understand and analyse temporal dynamics of rice production and import, a study was carried out by using secondary data during the period from 2009 to 2018. The objectives of the study were to analyses temporal changes and dynamics of rice production and import in Nepal. The study used Compound growth rate and Markov chain analysis to assess the pattern of temporal changes in production and import of rice in Nepal for the last one decade. The synthesis of the analysis is presented in both tabular and graphic forms. The results revealed that Nepal is importing rice in increasing trend and not being able to meet national demands despite some increase in rice production and productivity in the last decade. Imports of rice were found in four harmonized system codes from 18 countries and the value of rice import is mounting in recent years. In addition, Compound growth rate analysis showed that the rice import quantity and value were increasing at the rate of 24.48 and 38.11 percent per annum respectively, while production growth was hovering below less than 2% per annum. The higher growth rate of value than quantity showed that mainly import is concentrated on fine and aromatic rice. Further, the study also reveals the direction of trade using Markov chain analysis, which shows that among selected countries, two countries India and the USA were more stable rice exporters to Nepal while China, Thailand, and Italy were less stable. The study implies that import substitution can be done by increasing productivity with increase use of high yielding hybrids and fine and aromatic rice.","PeriodicalId":31348,"journal":{"name":"Journal of Nepal Agricultural Research Council","volume":"7 1","pages":"97-108"},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48319918","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}

A research was conducted in December, 2019 to examine the economic viability of organic rice farming and factors affecting its adoption. Fulbari area of Chitwan district of Nepal was purposively selected for this study on consultation with Agriculture Knowledge Centre, Chitwan and review of past works which showed good practice of organic rice farming. A total of 100 farm households, 50 organic and 50 inorganic were selected using simple random sampling. Primary data were collected through a pre-tested semi-structured interview schedule, while secondary data were collected from related publications. The probit regression analysis showed that the six variables were statistically significant for the decision to adopt organic rice farming, they are: number of schooling years of the household head (p= 0.014), annual household income from agriculture (p= 0.012), membership of any agricultural organization (p= 0.000), subsidy in other inputs in addition to seed and fertilizers (p= 0.000), area of rice cultivated land (p= 0.007) and awareness on climate change (0.086). The benefit cost ratio of organic rice production (2.2) was higher as compared to inorganic (1.9) which showed that the profitability in organic rice production was higher than in inorganic. Furthermore, indexing identifiedlengthy certification process (0.85) as the first major hindrance in adoption of organic rice farming followed by lack of proper organic market (0.68), high cost of organic seed and fertilizer (0.56), lack of knowledge and trainings on organic farming (0.48) and lack of government support such as grants and premium price (0.44) as the second, third, fourth and fifth hindrances respectively.

Four fodder combinations; teosinte mono crop, teosinte+ cowpea, tesosinte+ rice bean, and teosinte+ lablab bean was arranged to cultivate in three different date of sowing in the field in a Split Plot Design with 5 replications. Main plot treatments were different sowing dates and sub-plot treatments were combinations of fodder species. Dry herbage mass production, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and Ash were determined. The results showed that the significantly the highest Dry herbage and CP were obtained from fodder combination teosinte+ cowpea if sown at 18th April, whereas the significantly highest mean values of ADF and NDF were obtained for teosinte mono fodder crop. However, the lowest average value of ADF and NDF was obtained for fodder combination teosinte with cowpea. The average value of Ash and ADL of both harvest for fodder combination and date of sowing was statistically similar (p>0.05).
