abstract
The field experiment was conducted during Rabi season of 2015 at Viswavidyalaya farm on rapeseed with variety Benoy (B9) to study the effects of three major pests (weed, insect and pathogen) on biological productivity Laid out in paired plots for weed, insect and diseases the six plots were replicated six times for analyzing under T test. Losses due to the identified invading weed, insect and pathogen pests contributed to respective percentages of 19.89, 32.10 and 11.71 in seed yield and 5.79, 2.97 and 4.03 for oil content. Eco-safe managements, within 30 DAS, avoided yield loss by weed while insects and pathogens were controlled beyond 40 DAS. These findings may help farmers to strategize their crop protection plan accordingly in rapeseed in the light of individuals’ resource affordability.
