Background: Blackgram is the major pulse crop cultivated all over the India. The crop is resistant to unfavourable weather patterns and helps in enhancing soil fertility. It is a significant component of the Indian diet since it provides vegetable protein and balances the diet. About 26 per cent of it is protein, which is nearly three times more than cereal and other vitamins and minerals. In addition, it is utilised as nutrient-rich fodder, particularly for dairy cattle. A significant obstacle to expanding blackgram production in Chandel district, Manipur State is the technology gap. Frontline demonstration (FLD), is one of the most significant and effective methods for technology transfer. By using the newest technologies, Krishi Vigyan Kendra Chandel’s interventions aim to boost productivity and production. Methods: The study on Blackgram var. PU-31 under rainfed farming situations of Chandel district, Manipur was carried out by ICAR-Krishi Vigyan Kendra-Chandel, during Kharif 2017 to 2022 with the objectives to increase production and productivity of pulse in the district conducted in the farmers’ field for 118 hectares of land with all the scientific package of practices. Result: The average grain yield of 776.50 kg/ha was obtained in the demonstration plot with 38.13 per cent increase in yield over farmers practices. The technological and extension gap were 723.50 kg/ha and 214.33 kg/ha respectively. Similarly, technological index was decreased from 50.33 percent to 44.53 percent during the study period, revealing satisfactory performance of technological interventions which can further be improved by bridging the gaps with more efficient research and extension services.
