Evaluation of Trichoderma viride against chickpea wilt disease through front line demonstrations on farmer's field

The study was conducted on farmers field during 2018-19 to 2019-20 to evaluate the performance of Trichoderma viride against chickpea wilt disease. In demonstrated technology, 16.98 and 28.75 per cent in both the years increased chickpea yield. Average chickpea yield production was 19.2 and 19.8 q/ha was observed in demonstrated technology as compared to farmer's practices (15.6 and 15.4 q/ha. Net profit was also higher ('51420 and '69069 per hectare) in demonstrated technology. Whereas, it was' 36960 and '48159 per hectare in both the years. Cost benefit ratio was 1:2.89, 1:3.53 and 1:2.37, 1:2.78 in demonstrated technology and farmer's practices during 2018-19 and 2019-20 years, respectively.
