Abstract:
The field experiment on the impact of sowing periods of maize on the incidence of fall armyworm in maize was carried out at Entomology farm during rabi, 2019-20 and 2020-21. Among the different sowing periods, the lowest larval incidence (3.20 larvae/10 plants), plant damage (45.49%) and cob damage (30.11%) were recorded when the crop was sown during 3rd week of November followed by 1st week of November during both years i.e., 2019-20 and 2020-21. The highest larval incidence (6.09 larvae/10 plants), plant damage (75.62%) and cob damage (57.14%) were obtained in 1st week of October followed by 3rd week of October. Among six sowing periods, the highest grain (4624 kg/ha) and fodder (6579 kg/ha) yields of maize were produced during 3rd week of November and it was at par with 1st week of November. The lowest grain (2616 kg/ha) and fodder (4059 kg/ha) yields were recorded when maize was sown during the 1st week of October and it was at par with the 3rd week of October.
