Abstract:
Cowpea is one of the major pulse crops and the farmers were cultivating only the traditional varieties with non adoption of improved varieties and management practices resulted in poor yield. Hence to combat this problem frontline demonstration was conducted to demonstrate the potential of improved cowpea variety VBN 3 in ten farmers’ holdings of Tiruvallur district during Rabi season of 2018-2019. The crop was grown with improved crop management practices and compared with the farmers practice. The improved crop management practices consisting of new variety i.e., VBN 3, seed treatment with Rhizobium, soil application of TNAU Pulses micronutrient mixture @ 7.5 kg ha, spraying of Pulse wonder @ 5/ kg ha during flowering stage and improved pest management strategies for sucking pest. The results of the demonstration revealed that the demonstration of improved crop management practices recorded the higher number of pods per plant (36.5 t/ha) and pod yield (3.45 t/ha). Farmers practice recorded the lower number of pods per plant (26.4 t/ha) and pod yield (24.5 t/ha). The per cent increase in yield under demonstration over farmers practice was 24.5. The higher net income and benefit cost ratio (2.9) was realized in demonstration of improved crop management practices. The lower net income and benefit cost ratio (2.5) was recorded in farmers practice.
