 ABSTRACT

An experiment “Effect of weather parameters on growth, yield and insect pest infestation on brinjal varieties under different planting 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 shoot damage (weight basis) noticed during the all planting windows with the varieties Phule arjun (V1), Krishana (V2) and Panchganga (V3) the incidence of shoot damage (weight basis) was noticed on (0.11%) and intial stage in first week of August at 32nd MW and reached to its peak infestation (17.6%) during 2014.The end of July (31st MW) that continuously increased till at the end of october (41st MW) and decreased till end of December at 48th MW during 2015. The initial infestation of fruit damage of the pest was noticed on 38th MW to 48th MW on weight basis (7.42%) during reproductive stage in last week of September and reached to its peak infestation in 41st MW (17.7%) during the second week of October. Which further decreased during 48th MW with fruit infestation (4.80%).Among the Brinjal varieties, higher incidence L. orbonalis of was recorded on variety Panchganga (V2) and minimum was recorded on Phule Arjun (V3). Timely sowing on 31th MW (P1) and 32th MW (P2) recorded lower incidence of L. orbonalis whereas, crop sown delay during 34th MW (P4) recorded the maximum incidence.
