Impact of Date of Sowing and Weather Parameters on Insect Pests Infesting Summer Mungbean

Abstract

An experiment was conducted at Pulses Research Station, SDAU, Sardarkrushinagar during summer 2021 and 2022 to find out the insect pests attacking mungbean crop sowing at different dates to determine the optimum date(s) of sowing. It is seen that the incidence and population fluctuation of various insect pests was very much dependent on the prevailed climatic conditions of the cropping season. Study on the impact of date of sowing on sucking pests revealed that the sucking pest populations of whitefly, leafhopper and thrips were significantly high during the crop sown on February 15 and March 8 during both years, and high pod borer damage and low yield were also recorded on this date of sowing. Sucking pest population and percent pod borer damage were comparatively low on the date of sowing on February 26th, and the highest yield was also recorded on this date of sowing. The last week of February is advisable for sowing summer mungbean to get a higher yield and the lowest sucking pest and pod borer populations
