Impact of staggering in dates of transplanting on the incidence of yellow stem borer (Scirpophaga incertulas Walker) in aromatic rice

A field experiment was conducted to study the effect of different dates of transplanting on the incidence of yellow stem borer on aromatic rice variety Birsa ViSash Sugandh-L Pooled mean of two-year data indicated that early planted crop had least incidence of dead heart and white ear head (2.30 & 1.86 %) followed by normal planted crop (5.14 & 6.38 %) and late planted crop (10.83 & 13.61 %). Incidence of dead heart and white ear head had bearing in terms of grain yield, which was maximum in early (43.89 q ha^-1) followed by normal (38.44 q ha^-1) and late (34.00 q ha^-1) transplanted rice.
