Abstract: A field experiment was conducted during 2016 and 2017 at Instructional-cum-Research (ICR) Farm of Assam Agricultural University, Jorhat to work out the optimum irrigation scheduling on the transplanted autumn rice with alternate wetting and drying technology. In both the years, irrigation at 15 cm depletion of water from soil surface gave the highest grain yield and straw yield. The growth characteristics in terms of plant height, number of tillers per hill, CGR and RGR and yield attributing characteristics like number of effective tillers per hill, length of panicle, number of grains per panicle recorded the highest values under irrigation at 15 cm depletion of soil surface. The treatment also recorded the highest Crop Water Use Efficiency during both the years. The benefit: cost ratio was also found to be highest under this treatment.
