Validation of non-chemical IPM and INM technologies on brinjal through farmers' participatory approach.

Large-scale non-chemical IPM and INM technologies (Organic) along with IPM farm trials were carried out on brinjal (Solanum melongena L.) in Raispur village, Ghaziabad, Uttar Pradesh during 2006–07 and 2007–08 in a Farmers’ Participatory mode. Farmers’ practices (FP) consisting entirely of pesticidal sprays were also included in trial. The non-chemical (organic) integrated nutrient and pest management technologies, which included growing of greengram/Dhaincha and turning it in soil, application of FYM @ 20 tonnes/ha fortified with Trichoderma sp., seedling dip before transplanting in Phosphorus solubilising bacteria (PSB), VAM application around plants, erection of bird perches and pheromone traps @ 12/acre for shoot & fruit borer, soil application of neem cake, need based sprays of 5% NSKE, releases of Trichogramma sp @ 1.5 lakh/ha for shoot and fruit borer and clipping, collection and destruction of damaged shoots and fruits; though resulted in lower yields (341.2 and 290.6 q/ha) and so the lower CBR (1:1.72 & 1:1.47) in non-chemical (organic) trial than IPM- yield (424.47 & 376.0 q/ha); CBR (1:2.34 and 1:2.19) and Farmers’ Practices - yield (381.2 and 334.05 q/ha); CBR (1:2.06 and 1:1.89)), but yielded clean and better quality produce as reflected by pesticide residue studies. Therefore, the IPM technology used was not only directly environment friendly but also more sustainable vide increase in biodiversity (natural enemies, soil flora and fauna).
