Yield and economic analysis of rajmash varieties: A case study on improved technologies

This study evaluates the impact of improved Rajmash varieties and line sowing technology on yield and economic returns. The study presents an economic and agronomic evaluation of different Rajmash (kidney beans) varieties based on their yield, net returns, and benefit-cost (BC) ratios. A total of five Rajmash varieties—Baspa, Jawala, Triloki, Chitra, and Capsule—were demonstrated across multiple field trials to assess their potential in enhancing productivity compared to local checks. Among the varieties tested, Baspa exhibited the highest average yield of 18.5 q/ha, achieving a 64.44% increase over the local strain, with corresponding high economic returns. Capsule and Triloki followed closely with average yields of 17.9 q/ha and 17.8 q/ha, showing similar yield increases. The gross cost for all improved varieties was Rs. 90,000 per hectare, while the local strain required Rs. 80,000 per hectare. Baspa recorded the highest net return of Rs. 298,500 per hectare, followed by Capsule and Triloki, significantly outperforming the local strain's net return of Rs. 143,650. The BC ratios for the improved varieties ranged from 2.76 to 3.32, far surpassing the local strain’s ratio of 1.80. The analysis highlights the superior yield, profitability, and economic efficiency of improved Rajmash varieties, with Baspa, Capsule, and Triloki emerging as the most viable options for maximizing productivity and returns. The use of line sowing and optimized seed placement further enhanced the performance of these varieties.
