Abstract: An experiment was carried out at experimental farm of Department of Agricultural Meteorology, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during Kharif season 2015 entitled “Influence of dates of sowing on kharif green gram [Vigna radiate (L.) Wilczek] varieties under varied weather conditions” to find out most suitable week for sowing of Green gram in kharif season and to work out the correlation between yield of green gram and weather parameters. The experiment was conducted in Spilt plot design with three replications. Treatments comprised of three sowing dates in main plot D₁(25MW), D₂ (26MW) & D₃ (27MW) with four varieties in sub plot viz. BM-4, BPMR-145, BM-2003-2 and BM-2002-1.The crop was sown with spacing 30×10 cm. Gross and net plot size viz. 4.5 m x 4.0 m and 3.9 m x 3.6 m respectively. The result obtained from experiment revealed that all biometric observations (Plant height(cm), number of functional leaves, dry matter (gm), number of pods per plant) and yield of kharif green gram were significantly highest in first date D₁ 25 MW (18 to 24 June) as compared to other date of sowing. The green gram variety BM-2003-2(510 kg ha^-1) was found to be highly productive as compared to BM-2002-1(467 kg ha^-1), BM-4 (402 kg ha^-1) and BPMR-145 (346 kg ha^-1). The correlation study was carried out between weather variables prevailed during (P₁) to (P₅) growth stages of different varieties under different sowing dates. The correlation coefficient showing degree of association between seed yield and weather variables prevailed during growth stages of green gram crop. Rainfall and rainy days were found significantly negative correlated at P₂ (-0.663*), (-0.597*) and P₃ (-0.665*), (-0.661*) respectively.
