Therefore, the study evaluated the performance of foliar-applied boron in mitigating that problem towards sustainable aman rice production. A field experiment was laid out in a randomized complete block design where different levels of boron viz. 0, 50, 100, 150, 200, and 250 ppm were foliar-sprayed at 33 and 47 days after transplanting (DAT) to a popular aromatic rice cultivar Kataribhog grown in late monsoon. Data were collected on phenology, SPAD value at variable dates, pollen viability, boron concentration in leaves and grains, and yield traits and yield. The pollen viability increased by 81.6% for 200 ppm boron. Boron decreased flag leaf weight but increased panicle weight. Simultaneously, it decreased flag leaf SPAD value and subsequent increase in grain yield, which indicates profound flag leaf reserves translocation into the grain. Foliar-applied B at 200 ppm showed a 32.4 and 40.9% increase of B in leaf and grain, respectively, and improved yield attributes resulting in increased grain yield by 47.0%. The grain yield had strong positive relations with the B content in leaf and grain, and yield contributing characters. The results conclude that foliar-applied appropriate dose of B can reduce spikelet sterility, individual grain weight and eventually enhance grain formation towards increasing yield in late sown aromatic monsoon rice.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88658804","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}

It plays a pivotal role in pollination, environment conservation, and the maintenance of biodiversity. Although Bangladesh has a favorable ecological condition for beekeeping, only a fraction of its potential is being utilized. To identify the reasons behind it, this paper reviews the socioeconomic status of the beekeepers, the problems faced by them in rearing honey bees, and in the processing and marketing of bee products. It also highlights the modern technologies that can be adopted to improve the beekeeping sector. Reviewed literature shed light on the constraints in beekeeping as poor educational status, inadequate training facilities, and lack of utilization of modern scientific instruments. This situation is further worsened by the adverse effects of pests, diseases, and the indiscriminate use of pesticides in bee flora. Furthermore, the lack of modern technologies to extract the byproducts, added with poor marketing strategies, hinders potential income in local and foreign markets. Along with the introduction of up-to-date tools and technologies, the government and non-government organizations should collaborate to alleviate the threats faced by this sector to make it more profitable.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84843817","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}

Could the adoption of ICT be the means to achieve agricultural sustainability in developed and emerging economies? A startling plunge of food yield growth rates and risks of food insecurity in the future, especially after the global population projection of 9.7 billion people by 2050, highlights the pertinence of this question which finds no clear insights in the past literature. Not every person has the same internet access, communication tools, the same level of information approach, or makes the same benefit of available digital gadgets. Digital dividends have lagged the ICT penetration behind. ICT tools have been unevenly distributed. Developed economies have been able to make use of such tools as a support for development of sustainable agriculture. However, this case has potentially not been achieved in emerging economies due to the illiteracy of the farmers. This suggests the need for extension education, ICT tools demonstrations with application, investment in technology, training programs, workshops, and so on. The internet has been accessible to 86.6% of the developed countries, while it has just been 47% of people from developing ones. So, future research should focus on the strategies to increase the application of ICT tools in farming to bring agricultural sustainability in both developing and developed economies.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"111 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77340445","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 address the problem of resource conservation, an experiment was conducted in Kaski, Nepal during the rainy season of 2019. The experimental set up was in strip plot design consisting of three crop establishment methods(i) zero-till dry direct-seeded rice (ZT-DSR), (ii) reduced-till dry direct-seeded rice (RT-DSR) and (iii) transplanted rice (TPR) and four site-specific nutrient management (SSNM) options(i) nutrient expert (NE Model), (ii) leaf color chart (LCC), (iii) chlorophyll content meter-200 (CCM-200) and (iv) farmers fertilizer practice (FFP) with three replications in the fields. Among the establishment methods, TPR performed better in terms of grain yield and nutrient uses, whereas ZT-DSR was superior in terms of profitability and energy use. Among the nutrient management, CCM-200 showed promising performance with significantly higher grain nitrogen uptake (60.5 kg ha−1), straw nitrogen uptake (24.11 kg ha−1) and total nitrogen uptake (84.6 kg ha−1) than other nutrient management practices. The energy input in ZT-DSR and RT-DSR were 41.8% and 32.9% lower than the TPR. The energy use efficiency (EUE) was higher in ZT-DSR (15.79) and FFP (15.07) as compared to other crop establishment methods and fertilizer management approaches. The ZT-DSR with FFP had the highest EUE (20.94) followed by ZT-DSR with LCC (15.0). Whereas, the highest grain yield and B:C ratio was recorded on TPR with CCM-200 and ZT-DSR with CCM-200 respectively. Thus, considering the great importance of yield and profitability at the farmers’ level, combination of ZT-DSR and CCM-200 may be recommended to farmers.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77629005","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}

Traditionally, a variety of broad-spectrum chemical insecticides are being used to control this pest which is detrimental to beneficial insects and the environment. Hence, sustainable management was required. In the present study, as an alternative to conventional insecticides, we have tested: insecticides claimed to be least toxic to the environment (cypermethrin and carbofuran), botanicals (neem oil and mahogany oil) and two non-chemical measures (wood ash and wood ash combined with lime). Cypermethrin and neem oil followed by carbofuran were most efficient to minimize aphid infestations. Comparing to the untreated control plots, reduction of overall percent infestations of plants (74 79%), leaves (74 90%), twigs (48 61%) and pods (64 77%) were obtained through the application of cypermethrin, neem oil and carbofuran. Mahogany oil, wood ash solely and wood ash + lime were also found effective compared to the control plots. Therefore, cypermethrin and neem oil could be the first choice for the mustard growers followed by carbofuran to manage mustard aphids effectively. Mahogany oil followed by wood ash combined with lime and wood ash alone can be suggested only when aphid infestations remain at the lower level.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86661092","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 this research, major focus was given on the current status and prospects of local salt tolerant rice cultivation in coastal areas of Bangladesh taking five years information under consideration from 2016 to 2020. Thus, a survey was conducted in the selected coastal region of Bangladesh by using data of 90 households through structured questionnaire. Research findings revealed about 80 indigenous rice genotypes grown in saline areas with their present characterization and market demands that had worthy potential to grow and expand further. The market value of these genotypes are very high and required very low labor and fertilizer cost. This survey revealed numerous weaknesses, including low yield, longer maturity time, lack of trustable seed sources, farmers’ knowledge, switching towards shrimp cultivation, less marketing facility, poor coordination with related organizations and limited financial and management planning. These limitations hampered the cultivation potentials of the local cultivars. This survey work also suggested farmer’s level recommendation for flourishing the cultivation of these local cultivars to a profitable level.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80455693","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}
