In Nepal’s agricultural sector, rice accounts for the largest share of the Agricultural Gross Domestic Product (AGDP), comprising approximately 20%. However, the absence of appropriate policies poses a significant challenge to the sustainable production of rice in Nepal. This study aims to assess the various policy dimensions of the sustainable rice industry in Nepal and compare them with the policy implications in neighboring South Asian countries such as India, Pakistan, and Bangladesh. The study draws on secondary sources of information for its analysis. The findings reveal that Nepal lacks a comprehensive rice policy, while its existing agriculture policy is characterized by confusion and contradictions. To attain self-sufficiency in food production, it is imperative to establish a comprehensive rice policy in Nepal and implement price subsidies on diverse inputs, as observed in neighboring countries which will ultimately contribute to enhancing the sustainability of the rice industry and promote the goal of food self-sufficiency in Nepal.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":"23 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90275664","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}

Deductive research approach employed through household survey using semi-structured questionnaire with 115 respondents for research work. Out of 23 documented plants, Cuscuta reflexa Roxb., Mimosa pudica L. , Azadirachta indica A. Juss, Achyranthes aspera L. and Acorus calamus L. were screened for further phytochemical analysis based on fidelity level. Five treatments maintained as 3 different concentrations (5, 10, and 15% of stock solution), and control were arranged in a completely randomized design with three replications for evaluating allelopathic potential where selected botanical extracts on germination, radical, and plumule growth of wheat seedlings were examined under invitro condition. Mimosa pudica L. had the highest alkaloid (15.39%), Cuscuta reflexa Roxb. had the highest terpenoid (9.17%) and Acorus calamus L. had the highest saponin (5.49%) when calculated via gravimetric method. Germination, radical and plumule growth found under control treatment were 3.24ab±0.09, 2.94a ±0.09cm and 2.70a ±0.17cm respectively. The stock solution of Acorus calamus L. with 15% concentration extract resulted in the maximum reduction of radicle length (1.14e ±0.22cm) and plumule length (1.04h ±0.17cm), along with heavily controlled germination (1.05f ±0.17) of wheat seedlings. Thus, Acorus calamus L. proved the highest allelopathic potential on wheat seedling growth indicating further investigation on other crops.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":"90 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74817025","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}

There were significant (P<0.05) differences in the observed parameters like number of seedlings emergence, number of seedling establishment, number of leaves, seedling height and diameter of seedling stem among the tested growing media. The highest seedling emergence of tomato and sweet pepper were recorded in cocopeat as a growing media. After 30 days after seed sowing (DAS) in tomato, the highest number of seedling (103.5) were found in Cocopeat and the tallest seedling height (19.92 cm) was found in Vermicompost+ perlite. Similarly, in Capsicum (40DAS), the highest number of seedling (83.5) were found for the growing media Cocopeat only, followed by Vermicompost + Perlite (78) and the tallest seedling height (13.89 cm) was found in Vermicompost+Vermiculite grown seedlings. The good root plug formation was found for the use of cocopeat. Therefore, use of vermicompost or FYM in the mixed form with cocopeat or the soil as a growing media would be sustainable technology for commercial seedling production of vegetables.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":"158 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77138539","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}

BLASTN was performed to identify the similarities with the sequences of the National Center for Biotechnology Information (NCBI) Database. Evolutionary divergence between the sequences was computed using Maximum Composite Likelihood Model. Sequences were analyzed using Maximum Likelihood Model and Tamura-Nei model to construct molecular phylogeny. BLASTN and molecular phylogeny confirm all the samples to be Coffea arabica. Evolutionary divergence in pairwise comparison was found to be 0% to 4.3%. Divergence of 4.3% was detected between CDC-S21 and CDC-S73.

Fine, medium, coarse landraces were further classified into aromatic and non-aromatic. Some of the aromatic landraces popularized by their local dialect names as Basmati anadi, Basmati anpjhutte, Choti basmati, etc. were cultivated in diverse environment by local farmers but utilization in national rice improvement program is insufficient. Just handful of landraces were used as parental lines to develop improved varieties viz. Jarneli in Khumal-2, Pokhreli masino in Khumal 4, Khumal -5 and Palung 2, pureline of Jethobudho as Pokhreli jethobudho, pureline of Lalkabasmati as Lalkabasmati. With the prevailing trend of fast-track registration of the exotic improved lines, our grassroots level efforts to study the genetic makeup and unique attributes of our landraces are overshadowed. However, Jarneli, Kalo marshi, Kalo nuniya, Mansara, etc. were found to be popular for traits nutritious, medicinal, abiotic stress tolerance and resilience to low fertility soil. Furthermore, the modern tools of molecular characterization are yet to be utilized prominently to identify such valuable genes and understand their phylogenetic diversity rewarding for future rice breeding program.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":"31 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81070327","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}

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":"4 1","pages":""},"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}
