A filed experiment was conducted at ZARS, V. C. Farm, Mandya to enhance the crop and water productivity in sugarcane during 2017-18 and 2018-19. The design used was strip plot design with planting methods as a horizontal factor and irrigation scheduling as a vertical factor with three replications. Among the planting methods, 120 cm row spaced furrow planting with dhaincha green manure sowing at 30 DAP and mulching at 75 DAP recorded significantly higher cane yield (158.5 and 161.0 t/ha, respectively) as compared to others during both the years of experimentation. Among the irrigation schedules, IW/CPE ratio of 1.0 recorded significantly higher yield (168.1 and 170.8 t/ha, respectively) as compared to IW/CPE ratio of 0.60 (129.7 and 131.8 t/ha, respectively). The total water used was significantly lower in 120 cm spaced furrow planting with alternate skip furrow irrigation afte5r earthing + green manure mulching (1773 and 1751 mm, respectively) and it saved 16% of irrigation water. Scheduling of irrigation at IW/CPE ratio of 0.6 consumed lowest amount of irrigation water (1725 mm) and saved 18% of irrigation water.
