Effect of Non-Pesticidal Management (NPM) modules against Chilli pests

摘要

Investigations on the effect of NPM modules on the activity of pests of chilli viz., aphids, thrips, mites and fruit borer and yield, economics of NPM and conventional practices, carried out during 2012-213 and 2013-2014 kharif seasons at the Karchal village of Medak District, Telangana state. The experiment was laid out in RBD Randomized Block Design. Among the four NPM modules evaluated. The NPM module -I was found to be the most effective against aphids, thrips, mites and fruit borer H. armigera. In this, Maize as a barrier crop, marigold as a trap crop, Vermicompost 5 t/ha + Neem cake 10 q/ha, with sprays of Neemazal (3ml/l) at 5 and 11WAT (Weeks After Transplanting), Nimaasthram (250 l/ha) at 8 WAT, Agniasthram (6 lit/ha) at 13 WAT were applied , with the result a dry chilli yield 4.13 q/ha was obtained with a net return of Rs. 18,241/-. Whereas, in chemical Intervention, Recommended Dose of Fertilizer (M-IV) recorded a dry chilli yield 3.79 q/ha with a net return of Rs. 11330/-.
