abstract
Krishi Vigyan Kendra, Chandel, ICAR-Manipur Centre, carried out the study, which aimed to maximize the productivity of mustard var. NRCHB-101 under rice fallows on 80 hectares of land with 200 demonstrations in the farmers field of Chandel district of Manipur state under Cluster Front Line Demonstration during Kharif 2019 to 2023. Following the Kharif rice harvest in the northeastern states, rapeseed-mustard has a lot of potential when left in residual moisture. In Manipur's rainfed regions, it is a significant source of revenue, particularly for marginal and small farmers. According to the findings, farmers' practices yielded 7.25 q/ha, whereas enhanced technology achieved a mean yield of 9.54 q/ha, 23.96% higher. The range of the yield increase percentages using demonstration practices compared to farmer practices was 21.79% to 27.09 percent during 2019 and 2023, the technological or yield gap ranged from 3.85 to 5.05 q/ha, while the extension gap ranged from 1.95 to 2.75 q/ha. during the study period of 2019 to 2023. Similarly, over the study period, the technological index decreased from 36.07% to 27.50%, the benefit-cost ratio under demonstrations ranged from 1.92:1 to 2.41:1, whereas under farmer practices, it ranged from 1.56:1 to 1.86:1 during the study period respectively. In order to use the rice fallow areas for boosting cropping intensity as well as crop output and productivity, it is necessary to spread the improved technology among farmers through efficient extension techniques including training and demonstrations. Farmers should be urged to implement the suggested set of procedures in order to increase their profits.
