The field experiment was conducted during 2015-16 at Viswavidyalaya farm on summer rice (Oryza sativa L. cv. IET 4786) following system intensification methodology to study the effects of three major pests (weed, insect and disease) on biological productivity. There were two treatments, unprotected and protected which were replicated six times following pair plot technique design. The invading weed, insect and disease pests in the experimental plots were identified. Weed pest caused maximum loss in seed yield 37.02% followed by insect pest 27.9% and disease pest 15.6%. SRI productivity increase may be attributed to improvement in growth and yield parameters resulting from management of pests in the respective critical infestation period. Ecosafe integrated management of all these three major pests during the critical crop pest competition period effectively below the ETL minimized losses to sustain paddy productivity at desired levels.
