 ABSTRACT

An experiment “Effect of weather parameters on growth, yield and insect pest infestation on okra varieties under different sowing windows” was carried out at Faculty of Agriculture Department of Agricultural Meteorology Farm, Centre for Advanced Agricultural Meteorology, College of Agriculture, Pune during kharif seasons of 2014 and 2015.
The infestation activity of Earias vittella (weight basis)  noticed during the all sowing windows with the varieties Parbhani kranti (V1), Arka Anamika (V2) and Phule Utkarsha (V3) the incidence of Earias vittella (weight basis) was noticed (0.12%) during first week of August (33rd MW) and reached to its peak infestation (24.76%) during the second week of September (39th MW) during 2014 while initial infestation of the pest was (0.13%) during first week of August (33rd MW) and reached to its peak  (23.93%) during the second week of September (39th MW) during 2015, whereas crop sown on 30th MW (S4) recorded the maximum incidence (0.60 to 28.29%).
            Among the okra varieties, higher incidence of Earias vittella was recorded on variety Arka Anamika (V2) and minimum was recorded on Phule Utkarsha (V3). Timely sowing on 27th MW (S1) and 28th MW (S2) recorded lower incidence of Earias vittella whereas, crop sown delay during 30th MW (S4) recorded the maximum incidence.

Keywords: Earias vittella (weight basis), MW, Infestation, Sowing windows.
