Abstract

Crop water availability was worked out for deep black soil region of Bijapur area based on daily water budgeting. Though Bijapur received low rainfall annually, the precipitation  received in the months of June, July and August was sufficient for soil moisture accretion and provided a favourable soil water environment for the crop growth of post rainy season at 75 per cent probability. Further rains from September onwards help in improving the moisture condition. A high correlation coefficient of 0.8359 was obtained between the soil moisture available at the end of 37th week (16 September) and accumulated rainfall up to that period. The probability of receiving sowing rains during 37th to 41st. weeks was favourable. If crops could be established by October, It was found that the soil moisture environment will be optimum to, meet the water requirements of rabi crops on the average in 3 out of five years.
