Abstract

The influence of green manure, nitrogen levels and plant population with insecticide treatment on the incidence of rice stem borer (Scirpophaga incertulas Wik.) in kharif and rabi seasons revealed that combination of green manure and plant population had no influence on the incidence of dead heart, but 150 and 200 kg N/ha applied plots recorded significantly higher dead hearts. White ear incidence was significantly higher at high nitrogen levels and at the population level 80 hills/m² which was on par with 100 hills/m2 as compared to 66 hills/m².
