Abstract

                                An attempt was made at Salkuti (W.B) to evaluate the water requirement of rice grown In winter (boro) season. It was found that during the baro season the water requirement of rice was 749.20 mm, of which G11.40 mm was evapotranspiration and rest 137 80 mm was percolation it was found that the crop coefficient was linearly related to the days after transplanting. It was also found that the deep percolation can be predicted to a reasonably good accuracy using the depth of saturated water front below ground level as suggested by Denial Dicker (1969).
