Abstract: The field experiment was conducted at department of agricultural meteorology, college of agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani field entitled Performance of soybean (Glycine max) varieties under varied weather condition. The experiment was laid in split plot design, gross plot size was 5.4 m x 3.6 m and 4.5 m x 2.7 m net plot size, replicated thrice in which four sowing dates were imposed as a main treatments and four varieties were tested as sub plot treatment. The crop was sown on 27 MW took maximum calendar days, growing degree days, photo thermal unit, helio-thermal unit to attend different phonological stages till maturity which reduced significantly with subsequent delay in sowing time. The grain yield recorded in 27 MW were significantly highest to rest of sowing dates. The significant reduction in grain yield of timely sown varieties was recorded when sowing was delayed sowing dates. Among the varieties highest grain yield of 2611 kg ha-1 was recorded in varieties MAUS-158, which was significantly superior over MAUS-71, MAUS-81 and JS-335. Among the varieties (MAUS-158) took highest calendar days growing degree days, photo thermal unit, helio-thermal unit to reach the maturity. The variety (MAUS-158) recorded the highest grain yield at 27 MW sowing as compared to all other sowing dates.
