abstract
A study was conducted during the 2023 kharif season at the Experimental Farm of the Department of Agrometeorology, College of Agriculture, VNMKV Parbhani, to explore the relationship between crop growth and weather conditions for soybean. The experiment utilized a split-plot design and included four dates of sowing (25^th MW, 26^th MW, 27^th MW, and 28^th MW) and three varieties of soybean: MAUS-158, MAUS-162, and JS-335. The gross plot size was 5.4 m x 3.6 m, and the net plot size was 4.5 m x 3.4 m. The results indicated that soybean yield was significantly highest for the crop sown on D1 (1902 kg ha⁻¹), with a decline in yield observed as sowing was delayed, reaching a minimum of 923 kg ha⁻¹ on D4. From the varieties, MAUS-158 achieved the highest yield at 1693 kg ha⁻¹. Statistical analysis revealed that the vegetative and grain formation stages of soybean were most sensitive to weather parameters. Rainfall, number of rainy days, humidity, and soil moisture positively impacted soybean yield, while temperatures and sunshine duration had adverse effects on yield in the Parbhan region.
