An experiment was conducted at Research Farm, IGKV, Raipur (C.G.) during summer season 2013. Treatment consisted of two rice varieties (MTU1010 and IR64) as main plots and five drip irrigations (0.6, 0.8, 1.0, 1.2 and 1.4 IW: CPE ratio (Irrigation Water and Cumulative Pan Evaporation Ratio), micro sprinkler irrigation once in three day and flooding as sub plots. Panicle length, panicle weight, sound grains penicle-1 and numbers of grains panicle-1 were statistically similar in drip irrigation at 1.4, 1.2 and 1.0 IW:CPE ratio and traditional flooding. The maximum seed yield was recorded in drip irrigation at 1.4 IW: CPE ratio which was at par to traditional flooding and drip irrigation at 1.2 IW: CPE ratio but these treatments were significantly superior over rest of the treatments. Drip irrigation at 1.4 IW: CPE ratio reduced input cost by 14% and increased net income by 33% over traditional flood irrigation. The water use was the maximum in flooding (3340 mm) followed by micro sprinkler irrigation (1417 mm) and drip irrigation at 1.4 (1300 mm), 1.2 (1152 mm) and 1.0 (948 mm) IW:CPE ratio. Drip irrigation at 1.4 and 1.2 IW:CPE ratio saved 63 and 59 percent of irrigation water respectively over flooding, indicating that cropped area under summer rice can be doubled with same quantity of available water by using drip irrigation without sacrificing grain yield.
