Productivity enhancement in black gram by cluster front line demonstrations

The cluster frontline demonstration (CFLDs) on black gram was conducted by Krishi Vigyan Kendra, Nagapattinam in four villages namely Nangudi, Neduvasal, Kuttramporuthanirrupu and Aarpakkam during the rabi season of 2015–2016. The results revealed that improved seed of VBN 6+ seed treatment (trichoderma viridi 5 g/kg + Rhizobium spp 25g/kg+ PSB 25g/kg) + plant protection (pheronomone trap, yellow sticky trap + insecticide) recorded average highest yield 5.25 q/ha followed by 4.65 q/ha in control plot. Benefit cost ratio for demonstration and control was 3.42 and 3.26 respectively. It can be concluded that the black gram production could be enhanced by encouraging the farmers through adoption of recommended technologies which were followed in the Cluster Front Line Demonstrations.
