Blackgram is and important food legume widely consume in India. It also plays an important role in sustainable agriculture enriching the soil through biological nitrogen fixation. Krishi Vigyan Kendra, Raisen (M.P.) during the period from 2007–08 to 2009–10 conducted a total 36 frontline demonstration of blackgram crop. The highest seed yield (9.89 q ha−1) was recorded in the year 2009–10. In FLD, it was 46.51% more over the farmers practice (6.75 q ha−1). Average extension gap was recorded 2.53 q ha−1 and average technology index was recorded 24.36 percent. The technology gap was ranged between 2.11 q ha−1 to 3.57 q ha−1. The productivity gain under FLD over farmer's practice created greater awareness and motivated the other farmer's to adopt appropriate production technology of the crop.
