Abstract:
The field experiment was conducted on the influence of different planting periods on damage of rice leaf folder, Cnaphalocrocis medinalis Guenee (Pyralidae: Lepidoptera) during Kharif 2020 to 2021. Result revealed that significantly lowest leaf folder incidence was recorded in the early transplanted crop (2.97% DL), followed by normal transplanted crop (6.61% DL). Significantly highest % damaged leaves were observed by leaf folder in late transplanted crop (8.27% DL). Grain yield showed significantly highest grain yield (4981 kg/ha) while straw yield (5634 kg/ha) was found in early planting period and it was at par with normal planting period 4587 kg/ha grain yield and 5217 kg/ha straw yield. Significantly lowest grain yield (4362 kg/ha) and straw yield (4971 kg/ha) was found in late planting period.
