AMA, Agricultural Mechanization in Asia, Africa and Latin America (ISSN: 00845841) is a peer-reviewed journal. The journal covers Agricultural and Biological Sciences and all sort of engineering topic. the journal's scopes are in the following fields but not limited to:
The nanoparticles (NPs) refer to the matter at the nanoscale (1-100 nm). Despite their size, they are proving their efficiency in numerous domains. The agriculture sectors have also explored and are being benefitted by its novel applications. Previously, the NPs were synthesized through physical and chemical methods. However, those methods came with expensive and environmentally hazardous results. This diverted the research community towards the green route of NPs synthesis using the biological existents. The plants, due to their abundance, are considered to be an ideal candidate for the large-scale synthesis of NPs. The more the biological value, the more is the quality and stability of NPs. Considering this context, this review gives details on the medicinal plant-mediated green synthesis of NPs. This also discusses various applications and recent advances of NPs application in agriculture sectors.
The formulation of a strategy is to improve livelihood prospects of beneficiaries from an assessment of the potential and performance of the state's primary lac producing districts. This study is based on secondary data on lac production during Plan XI (2007- 08 to 2011-12) and Plan XII (2012-13 to 2016-17). Secondary lac production data was evaluated crop by crop and district by district, and the trend was examined. Few econometric measures, such as mean production, growth rate, and percent changes in mean value over the XII plan and XI plan period, were analyzed. West Bengal's contribution to national production declined from 6.97 % during the XI plan period to 3.56 % during the XII plan. During the XII plan, there is a 3.41 % decline in the share. During the XI plan, the state had a positive growth rate of 10.06 %, which dropped to 1.06 % during the XII plan. Bankura district had the highest % change in mean value from XI to XII plan, at 38.97 %, followed by Other minor lac producing districts combined (27.91 %), and Purulia district (26.35 %). However, the mean value decreases only in the Midnapur district (-63.33%) from XI to XII plan. The state as a whole recorded 41.82 % decrease in mean value over the XI plan. The decrease per cent is due to a decrease in the mean value of rangeeni and kusmi summer crop. There is a substantial decrease in rangeeni lac production in the Midnapur district. However, there is a substantial increase in the mean value of kusmi crop in Purulia and other districts together. In respect of instability in production during the XII plan, all direct recorded lower instability than states figure of 76.60 %.
In this investigation, biological management was examined to control Colletotrichum capsici caused anthracnose in chilli plants. Fungal antagonist Trichoderma spp. and local plant extracts were tested singly against the pathogen. In laboratory studies, it has been depicted that Eucalyptus plant extracts (at 20%W/V) and Trichoderma viride inhibited the mycelium growth of Pathogen to the magnitude of (81.11%) and (90.74%), respectively. Further studies in pot and field conditions revealed that Trichoderma viride was observed to be superior in controlling the incidence of chilli anthracnose disease (69.63% & 63.43%) in highly susceptible cultivar. Five Trichoderma species were also screened to check the chitinolytic enzyme. Out of these species, T. viride exhibited the highest chitin degrading activity which leads to maximum inhibition of the mycelial growth of the test pathogen. The findings indicated that leaf extracts of plants significantly reduced the pathogen growth in laboratory conditions only, whereas Trichoderma species were found superior in laboratory, pot and field conditions. Therefore, these findings undoubtedly supported the usefulness of antipathogenic Trichoderma in limiting the occurrence of anthracnose in chilli.
The current research was conducted in 2019 and 2020 during rainy (Kharif) seasons to determine various tillage crop establishment methods and nutrient management strategies that could be used to drastically reduce on various field inputs viz., water and nutrients for enhancing productivity, nutrient use efficiency and grain quality of Rice (Oryza Sativa L) in Typic Ustochrept soils. The outcomes revealed that conventional puddled transplanted rice (E1, CT-TPR) was recorded significantly higher grain yield (40.4 & 41.3 q ha-1), straw yield (62.7 & 63.8 q ha-1) than wide bed transplanted rice (E2, W Bed-TPR) While yield attributes, nutrient use efficiency and quality parameters of the rice grains were increased in E2 than E1 plots, during both years. The improvement in the grain yield was about 4.39 % and 4.03 per cent under E1 than E2 respectively. Among nutrient management treatments, higher crop yield and ANUE were recorded with the application of 100% RDF+FYM (5tha-1)+PSB(5kgha-1)+Azotobactor 20kgha-1 +ZnSO4 25kgha-1 (N6) over rest of the other treatments. The PNUE values ranged from 53.0 to 97.1 kg grain/kg N absorption, with the PNUE values falling as the N doses rose sharply and moreover higher PFP at STCR based NPK application + ZnSO4 25kgha-1 with 52.6% respectively. Results also indicated that quality of rice, higher value of minimum cooking time, elongation ration and water uptakes ratio were found in N6 treatment. Therefore, the study reveals that conservation tillage and nutrient management strategies may be more realistic solutions for sustaining the productivity and quality of rice crop.
The changing scenario in agriculture, economy and communication has also increased the need for improving the skills of extension personnel. The first step in improving the skills of extension personnel would be to assess their training needs. The study was conducted in the year 2020-21. The present study was conducted in the Department of Agricultural extension and communication and the Kota division of Rajasthan was purposively selected for the study. The respondents were the Agricultural extension functionaries and the sample size was 130. The important training needs aspects were subject matter and extension ability. The important training need areas identified in order of importance are Soil science, Agronomy Marketing, Govt. polices and post harvesting technology, Plant protection and Extension ability. As the training needs of extension personnel changed over time, hence, training needs assessment should also be done on a regular basis and the important areas in which the extension personnel needs training should be considered while planning training for the extension personnel. Thus, appropriate measures should be taken by the department and other training institutions in addressing their grievances.
