Performance Evaluation of Black Gram (Vigna mungo L.) under Cluster Front Line Demonstration Programme in Samastipur District, Bihar, India
2021
The Cluster Front Line Demonstration (CFLD) programme on black gram was carried out during 2017–18 in operational area of Krishi Vigyan Kendra, Samastipur. The plots were selected from different villages/clusters (each of 0.2-0.4 ha) from the district. The variety ‘PU-31’ was used in both the demonstrated plots and farmers fields. Fertilizer, herbicides, irrigation application and plant protection measures were taken as per improved package of practices. During the CFLD programme, it was found that the seed yield of black gram was 9.80 q/ha in demonstrated fields as compared to 6.10 q/ha seed obtained from farmers field. The technology gap was found to be 2.20 q/ha and extension gap 3.70 q/ha extension gap was found in that year. The technology index was 18.33 per cent. Higher gross returns (Rs 39200/ha), net return (Rs. 21600/ha and benefit-cost ratio of 2.22 were found in demonstrated fields as compared to benefit-cost ratio of 1.52 in case of local check. The significant yield is attributed due to introduction of new variety and management in cluster mode which facilitated better crop management.
