Impact of Cluster Front Line Demonstration (CFLD) on productivity and profitability of blackgram (Vigna mungo L.) under rainfed condition in Dibrugarh district of Assam

Blackgram is one of the important pulse crops cultivated during kharif season in Dibrugarh district of Assam. During 2022-23 and 2023-24, Krishi Vigyan Kendra, Dibrugarh conducted Cluster Front Line Demonstration (CFLD) programme on blackgram for 35 hectares (ha) area of high yielding variety (HYV) SBC 40 among 78 farmers covering nine villages, to study the impact of CFLD programme in terms of grain yield, extension gap, technological gap, technology index and additional return along with benefit-cost ratio through improved package of practices. The results revealed that, the mean yield of blackgram during both the years under demonstrated practices was 9.1 q/ha as against 5.8 q/ha from farmers practices. The mean extension gap (3.3 q/ha), technological gap (2.79 q/ha) and technology index (23.47%). The mean net return (Rs. 45050/ha) and benefit- cost ratio (2.94) of demonstrated practices was higher as against Rs. 25910/ha and 2.48, respectively under farmers practices. The results clearly concluded that, by the use of high yielding blackgram variety SBC 40 and improved package of practices remarkably increase the productivity and profitability of blackgram in Dibrugarh district of Assam.
