Abstract: A field experiment was conducted during kharif sessions of 2016 and 2017 at Agricultural Research Station (ARS), Gangavathi, UAS, Raichur, to study the effect of irrigation scheduling and fertigation on performance of drip irrigated direct seeded rice in clay soil. The experiment laid out in split plot design with four irrigation scheduling based on IW/CPE ratios assigned to main plots and four drip fertigation levels were allocated in subplots and replicated thrice. Irrigation scheduling at 1.50 IW/CPE ratio recorded significantly higher grain yield on average of two years (5060 kg ha-1), straw yield (5937 kg ha-1) and harvest index (0.46) but it was on par with 1.25 IW/CPE ratio (4875 kg ha-1, 5593 kg ha-1 and 0.47, respectively). Among the drip fertigation levels, drip fertigation at 125% RDN recorded (5049 kg ha-1, 5897 kg ha-1 and 0.46, respectively) followed by 100 RDN (4914 kg ha-1, 5651 kg ha-1 and 0.46, respectively). Among the interaction, irrigation scheduling at 1.50 IW/CPE ratio with 125% RDN recorded significantly higher growth, yield and yield attributes than the other treatment combinations.
