Validation of non-chemical IPM and INM technologies for Onion (Allium cepa L.) in a Farmers' Driven Approach

摘要

Non-chemical IPM and INM technologies (organic) along with IPM farm trials carried out on onion in Karnal, Haryana during 2015-16 and 2016-17 in a farmers' involving approach revealed lower yields (185.5 & 308 q/ha) and so the lower CBR (1:0.98 & 1:1.97) in non-chemical (organic) trial than IPM- yield (270 & 375 q/ha); CBR (1:1.78 & 1:3.18) and Farmers' Practices - yield (255 & 355 q/ha); CBR (1:1.65 & 1:2.92), but yielded clean/quality produce as reflected by reduced pesticide use. IPM technology was environment friendly that helped in increased biodiversity in terms of natural enemies.
