Abstract:
In North East India the productivity of pulse crop is low as because of improper soil nutrient management coupled with soil acidity problem. To popularize the technology of pulse production through soil nutrient along with soil acidity management and for analysis of yield gaps in Black gram (Vigna mungo L.) in Ri-Bhoi District of Meghalaya, a front line demonstration (FLD) was conducted at the farmers’ field in Ri-Bhoi District of Meghalaya. The demonstration was conducted at ten farmers’ field covering 4 hectares of land during the year 2016 and 2017. The results of the study revealed that the application of Lime 400 kg/ha + vermicompost @ 2.0 t/ha + 50% RDF (10:20:10 kg/ha) + 20 kg /ha Sulphur had recorded significantly higher yield i.e., 9.86 q/ha with B.C ratio of 1.85 followed by farmer’s practice (6.4 q/ha yield with B.C ratio of 1.44). Moreover, the soil nutrient status was also significantly improved at the time of harvesting as compared to farmer’s practice in both the years. Technology Gap of 2.14 q/ha, extension gap of 3.46 q/ ha and technology index 17.83 had been recorded. The technology index achieved from the demonstration showed the feasibility of the evolved technology at the farmer’s field. If the technology dissemination is successful in North East India with application of Lime with organic and inorganic fertilizers for yield improvement, maintaining the soil health, reducing the rate of chemical fertilizer in black gram crop (Vigna mungo L) the productivity could be improved attractively.
