Studies on the yield losses caused due to rice leaf defoliators and determination of eil by simulating artificial damage.

摘要

Experiments were conducted during kharif 2003, in Pantnagar, Uttaranchal, India, to assess the yield loss in rice cv. Pusa Basmati 1 caused by rice defoliators at 90 and 105 days after transplanting (DAT). The economic injury level was worked out as 14.49 and 18.74% leaf defoliation.
