Abstract Fieldexperiment was conducted during summer 2011 at ZARS, UAS, GKVK, Bangalore on red loamsandy soil to assess the yield, water requirement and water use efficiency in aerobic rice. The experiment was laid out in Factorial Randomized Complete Block Design with two genotypes and five irrigation schedules. The genotype MAS 868 recorded highest grain yield (82.67 q ha−1), straw yield (84.65 q ha−1) and water productivity (102.44 kg ha-cm−1). The irrigation schedule at 0.6 IW/CPE ratio from 15–45 DAS and 0.8 IW/CPE ratio from 46 DAS to maturity recorded significantly higher grain yield (78.49 q ha−1), straw yield (81.34 q ha−1) and water productivity (99.09 kg ha-cm−1) over the other irrigation scheduling. The total water used was recorded highest in genotype MAS 868 (80.88cm) and in irrigation schedules, irrigation scheduled at 0.8 IW/CPE ratio throughout (I2: 84.02cm) compared to others treatments.
