Abstract

Infestation by insect pests in soybean variety “JS 335” inflicted significant reduction in mean plant height during kharif 2021was (5.27%) and 2022 (10.11%). Likewise, the loss in mean number of pods/ plants, mean number of seeds/ pod and seed yield/ plant was 20.43 and 20.16; 8.45 and 15.28; 22.92 and 32.60% during 2021 and 2022, respectively. On the basis of difference obtained in net yield between protected and unprotected plots, the avoidable quantitative loss was estimated as 24.87% during 2021 and 23.22% during 2022.
