Among different agricultural goods produced in and exported from Nepal, the competitiveness of coffee has quickly increased in recent years, thus contributing to the improvement of rural livelihoods. This study was based on review of literature and analysis of secondary data/information. Statistical tools such as correlation analysis was also used to analyze data. According to the official records coffee production area has expanded from around 135.7 ha in fiscal year 1994/95 to 3052 ha in 2020/21 and the production has increased from 12.95 Mt. of dry cherry to 315 Mt. of green beans during the same period. Nepal’s coffee subsector is characterized by low productivity, low production and poor quality. Inter alia, it was mainly due to incidence of insect pests, production done by smallholder farmers in a widely scattered area creating problems in quality control and collection leading to higher cost. The good price, high demand and overwhelmingly organic system of production are the encouraging factors but the formidable challenge remains on fighting with white stem borer and providing incentives for small holder farmers throughout the relatively long gestation period of coffee crop. Apart from low production level, organic certification and quarantine requirements pose serious challenges to export. Coffee produced in Nepal is Organic & Fair-trade and is readily accepted as a Specialty Coffee in specific international markets.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75139617","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}

The area under wheat (Triticum aestivum) cultivation per household was 0.6 hectare with no significant difference between super zone of the Prime Minister Agriculture Modernization Project and non-super zone areas. The average production per household was 1814.5 kg whereas the yield was 3.3 mt/ha. The average cost of production was NRs. 64,526.62 per hectare and the B:C ratio was found to be 1.492. The Cobb-Douglas function showed that fertilizer, pesticide, land preparation, irrigation, and threshing costs were significant contributing factors to wheat production. The return to scale was found to be 0.261. An Index of severity was constructed to study the problems of wheat production in the study area.

The crop requires the right amount of nutrient at the appropriate time for optimal growth and production. However, the low availability, high cost, and inappropriate timing of applying nitrogenous fertilizers like urea have made it challenging for farmers to use the correct amount in their fields. Therefore, affordable and renewable sources of plant nutrients should be used to supplement chemical fertilizers. In addition to this, using organic sources can improve soil properties. To determine the effects of nitrogen supplied through different sources, an experiment was conducted in a randomized block design. There were eight treatments, each with a different combination of nitrogen supplied through urea and various organic sources as N1(100% rec N via Urea), N2 (50 % rec N via FYM + 50 % rec N via Urea), N3 (50 % rec N via PM + 50 % rec N via Urea), N4(50 % rec N via GM + 50 % rec N via Urea) , N5 (75 % rec N via FYM + 25 % rec N via Urea), N6 (75 % rec N via PM + 25 % rec N via Urea), N7 (75 % rec N via GM + 25 % rec N via Urea), N8 (Farmer practices (FYM 10 t ha-1)). The yield of potato tubers was significantly higher when recommended nitrogen was applied 50% through organic manure like poultry, FYM, and goat, and 50% through urea than other treatments, including farmer practice of using 10 t ha-1 FYM. However, the yield was statistically at par with nitrogen via sole urea. Additionally, the application of organic manures led to an increase in soil properties such as organic manure content, nitrogen, phosphorous, and potassium content. In conclusion, application of recommended nitrogen as 50% via organic manures like poultry, FYM, and goat, and 50% N via urea can enhance potato yield while also positively affecting soil properties.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136300000","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}

Nonparametric tests are used for non-normally distributed data, and parametric tests are used for normally distributed data. The study found high mortality and administrative obstacles of 68.60% and 48.60%, respectively. If the wrong choice of aeration method and equipment is made, more fish will survive in the retailer's shop and during transportation time. Fish Models II and III will be an alternative to the current method of transportation, which shows that increasing the tank capacity by one standard deviation increases fish survival by 0.7 and 0.65 standard deviations, respectively. To increase the dissolved gas, the survey suggests that transportation and aeration methods should be improved. This increases the volume of transportation while using the same resources, meeting market demands.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76949280","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}
