Abstract: Field experiment was carried out at Soil and Water Management Research Institute, kattuthottam, Thanjavur during rabi season of 2016-2017 to study the effect of crop establishment methods and irrigation scheduling on growth and yield of rice. The experiment was laid out in split plot design with three replication. The treatments comprised of three establishment methods viz., direct seeded rice, non puddled machine transplanted rice and puddled transplanted rice in main plots and seven irrigation scheduling practices in sub plots viz., alternate wetting and drying at 10 cm depletion of ponded water, alternate wetting drying at 15 cm depletion of ponded water, alternate wetting and drying at 20 cm depletion of ponded water, alternate wetting and drying at 10 cm depletion of ponded water and submergence at flowering, alternate wetting and drying at 15 cm depletion of ponded water and submergence at flowering, alternate wetting and drying at 20 cm depletion of ponded water and submergence at flowering and irrigation on the day of disappearance of ponded water. It was found that direct seeded rice recorded significantly higher plant height, DMP, productive tillers m-2, number of grains panicle-1, and grain yield compared to puddled transplanted rice and non puddled transplanted rice. Among the various irrigation scheduling practices, irrigation on the day of disappearance of ponded water recorded higher growth and yield parameters and it was on par with alternate wetting and drying at 10 cm depletion of ponded water and submergence at flowering. Crop establishment method and irrigation scheduling contributed significant influence on growth and yield of rice.
