 ABSTRACT

An experiment “Micrometeorological studies on growth, yield and pest infestation on soybean 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 2015 and 2016.
The infestation activity of Spodoptera noticed during the first sowing window 26th MW (D1) with the varieties MACS- 450 (V1), JS-335 (V2) and DS- 228 (V3) and KDS- 344 (V4) the incidence of Spodoptera was  ranged from  0.23 – 1.60, 0.10 – 1.67, 0.07 – 1.47 and 0.17 – 1.33 larvae/mrl with a peaks in 36th and 37th MW. Whereas, crop sown on 27th MW (D2) recorded the maximum incidence (0.13 to 1.13 larvae/mrl).
 Among the soybean varieties, higher incidence of Spodoptera and semilooper was recorded on MACS- 450 variety and minimum was recorded on Phule Kalyani. Timely sowing on 26th MW (D1) and 27th MW (D2) recorded lower incidence of Spodoptera and semilooper, whereas, crop sown delay during 29th MW (D4) recorded the maximum incidence.

Keywords: Spodopter, MW, Soybean, Sowing windows.
