Rainfall distribution is most adversely affected due to change in climatic conditions. Considering 26 years of rainfall data, rainfall characterization of Kolhapur region advocated that the best suited sowing dates for kharif crops is 23rd MW and 24th MW. The recent anomalies in onset and withdrawal of monsoon emerged with a need to develop an advisory for growers regarding sowing of soybean crop in particular. An experiment was therefore conducted with four sowing dates i.e. 23rd MW, 25th MW, 27th MW and 29th MW and four varieties such as Phule Agrni, Phule Kalyani, KS 103 and JS 335 tested in split plot design with three replications. This experiment was carried out at the Zonal Agricultural Research Station, Shenda Park, Kolhapur(Maharashtra) during kharif seasons for three consecutive years to study effect of different sowing dates on growth, yield and quality of soybean cultivars under rainfed conditions. The periodical growth observations and yield contributing characters were recorded as per the schedule. The results of this study revealed that the first sowing date of 23rd MW exhibited significantly highest number of pods per plant (40.04), test weigh (19.74) and grain yield of soybean (20.32 q ha-1) however, the second sowing date of 25th MW found to be closely and equally suited for kharif sowing of soybean crop. Delayed sowing of soybean revealed decline in yield irrespective of varieties tested. Among the varieties, Phule Agrani, recorded significantly highest number of pods per plant (39.59), test weigh (21.74), grain and straw yield of soybean 19.77 and 21.08 q ha-1 respectively. The interaction between sowing dates and varieties were found to be statistically insignificant.
