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":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":"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}

The objective of this study was to evaluate the commonly available fungicides (Carbendazim 50%, Fenamidone 10%+ Mancozeb 50%, Chlorothalonil and biocontrol agents (Trichoderma sps., Bacillus thuringiensis and Pseudomonas species) for their efficacy against Foc. The effectiveness of fungicides and biocontrol agents to Foc was examined in screenhouse. The experiment was laid out in a completely randomized design with three replications and eight treatments. Among the chemicals, the most effective fungicide to reduce Fusarium wilt severity (root disease) was Bavistin with an efficacy of 55.33% followed by Sectin 46.33% and Chlorothalonil 35%. Similarly, maximum efficacy over control was recorded in Trichoderma harzianum with 41% and lowest was 32% in Pseudomonas sp. In the case of leaf disease, the lowest severity was 21.33% recorded in Bavistin and highest was 40.33% in Chlorothalonil. Similarly, among biocontrol agents, the lowest severity was found in Bacillus thuringiensis whereas highest was found in Trichoderma viride. A Suppression of disease by biocontrol agents might be due to their fungicidal activity, which means they produce a variety of antifungal compounds. These compounds induce plant defense mechanisms. Further field evaluations of the fungicides and biocontrol agents are required to determine if the effect observed in the screenhouse can be integrated into field management of Fusarium wilt.","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":"90985004","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}

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":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":"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}

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":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":"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}

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.

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.

Potato production was identified as a profitable farming business with an average productivity of 18.95 t/ha with benefit-cost ratio of 1.59. The average per hectare total cost of production of potato was found to be Rs 660774.8 on mustang district. The study reveals that expenditure on labour wage and organic manure contributed more than three-quarters of total production cost of potato. There were no any significant differences between the different rural municipalities in terms of the total cost of production but a significant difference (1% level of significance) was observed over the production of potato per hectare. An increment in 1% cost of seeds was found to result in increase in 0.27% of income from potato production, however a diminishing return to scale (0.232) was revealed in the study.
