abstract
The Front Line Demonstrations (FLD) of groundnut were conducted during Rabi (2012-13 to 2014-15) and Kharif (2014-15) seasons to demonstrate production potential and economic benefit of improved technologies consisting suitable variety KCG 2 in Ramanagara, Kolar, Chikkaballapur and Tumkur districts of Southern Karnataka over the three years. Recommended dose of fertilizer, rhizobium, zinc and boron were applied along with use of improved variety. TMV2 variety which is age old variety was used in farmers practice as against new variety KCG 2 in improved technologies. The results of the demonstration indicated that the demonstration of improved technology with new variety Chintamani-2 (KCG-2) recorded higher mean pod yield of 2278.56 kg/ha with 20.43 per cent increase in pod yield over farmers practice which recorded mean pod yield of 1896.87kg/ha. The improved technologies recorded haulm yield of 5.29 t/ha with increase of 14.96 per cent compared to farmers practice (4.60t/ha). Higher mean net income of Rs. 58005.93/ha with an incremental Benefit: Cost ratio of 3.43was obtained with improved technologies in comparison to farmer's practices (Rs. 46217.14/ha). The frontline demonstrations conducted on field bean at the farmers' field revealed that the adoption of improved technologies significantly increased the yield as well as yield attributing traits of crop and also the net returns higher than the farmers' practices. Hence, there is a need to disseminate the improved technologies among the farmers with effective extension methods like training and demonstrations. Farmers' should be encouraged to adopt the recommended package of practices for realizing higher returns.
