Sixty Front Line Demonstrations (FLDs) on cotton intercropping with pulses were carried out in a total 60 hectares of 61 farmers’ fields in 23 villages in Madurai, Virudhunagar and Thoothukudi Districts of Southern Tamil Nadu during winter irrigatedor rainfed seasons (August 2018 to January 2017-2018, 2018-2019 and 2019-2020. The FLD on cotton intercropping with black gram and green gram were compared with farmers’ practice. In FLD, latest cotton varieties (SVPR 4, SVPR 5 and CO 17), black gram (VBN 6, VBN 8 and MDU 1) and green gram (CO 8) intercropping, balanced fertilizer application and integrated pest management practices were adopted. In farmers’ practice, use of mixed varieties, broadcasting, without intercropping, unbalanced fertilizer application and irregular use of insecticides were followed. The results revealed that adoption of improved varieties and integrated management practices recorded higher mean kapas yield of 2160 and 1583 kg/ha under irrigated and rainfed conditions, respectively as compared to famers method of cultivation (1836 and 1403 kg/ha). Thus the yield advantage of 17.58 and 13.02 per cent under irrigated and rainfed conditions, respectively than control was observed. Among the varieties, CO 17 performed better than other varieties during all the years of study. The Land Equivalent Ratio was more than one indicating the higher efficiency of yield production of cotton with intercropping of pulses than sole cotton. Higher mean net profit of Rs 52, 760/ha and Rs 36,298/ha under irrigated and rainfed conditions respectively were associated with the use of high yielding varieties and improved production technologies (Rs 29,165 and 20,674/ha) and higher benefit cost ratio than farmers’ practice. Thus cultivation ofnew varieties with improved production technologies gained an additional economic benefit of Rs. 28,642 and 16,895/ha as compared to existing varieties with farmers’ method. It can be concluded from the Front Line Demonstrations that adoption of modernvarieties of cotton with intercropping lead higher yield, better land use efficiency and higher economic benefits which will pave way for sustainable cotton production .
