Abstract: Module on Integrated pest management (IPM) in Pigeonpea was demonstrated in farmers’ field in Vellore and Tirupathur districts of Tamil Nadu during 2021 and 2022. The demonstrations on IPM recorded with an average grain yield of 1400 kg ha^-1 and 1420 kg ha-1 during 2020-21 and 2021-22, respectively as against the farmers’ practice which recorded 885 and 980 kg ha^-1, respectively. The significant higher yield in case of demonstrated plots resulted in 36.78 and 31.42 per cent increase over farmers’ practice due to lack of awareness and knowledge with the technology gap of 200 and 180 kg ha^-1. The technology index varied from 12.52-12.67 per cent and reflected the feasibility of the demonstrated technology in farmers’ field. With the use of improved package of practices on an average additional investment of Rs.7500 ha^-1 (2020-21) and Rs.7000/- ha^-1 (2021-22) was made for demonstrations. The excess expenditure incurred results in the highest net return in demonstration plots of Rs. 77000/- ha^-1 (2020-21) as compared to farmers’ practice of Rs.48675/- ha^-1 with 42.92 per cent increase in net return and Rs. 85200/- ha^-1 (2021-22) as compared to farmers’ practice of Rs.49000/- ha^-1 with 51.95 per cent increase in net return over farmers practice.
