A field experiment was conducted during 2016 and 2017 at Instructionalcum-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. | Water saving strategy in rice by alternate wetting and drying technology
