... Whereas, in case of untrained soybean growers the majority of soybean growers 60.00 per cent had low awareness level about function of Krishi Vigyan Kendra followed by medium 32.00 per cent and high 08.00 per cent, respectively. The results of this study are in same line of findings repeated by Gudade et al., [4] Thus, it can be concluded that in the study area, higher numbers of the trained soybean growers had high awareness level of about function of Krishi Vigyan Kendra due to the participation in training programmes & soybean growers field school conducted by KVK. The untrained soybean growers lacked this opportunity and hence, they showed lower awareness level about function of KVK. ...
... The main reason for its low productivity is its cultivation in rainfed conditions. Owing to this constraint the crop faces severe moisture stress during winter period [12]. Under such situation farmers have to depend largely on rain and in-situ soil moisture conservation practices. ...
... These projected drier conditions will negatively influence the habitat suitability of cardamom in the study area. Further, Gudade et al. [64] observed that declining soil nutrition and soil moisture are key drivers in reduction in crop productivity both in India and Nepal. ...
... However, the declining production during last decade due to various biotic and abiotic factors has raised serious concerns for its sustained production. Attempts to improve its production and quality using various agronomic and post harvest means have been reported [2][3][4] but efforts for its genetic improvement is still lacking. Being a crop of regional importance, genetic improvement program is needed to evolve superior genotypes/clones having tolerance to stresses along with high capsule yield. ...
... The foorkey disease is transmitted through aphid Micromyzus kalimpongensis and symptoms include production of bushy growth of stunted shoots which are sterile (Verma and Capoor 1964).
