The study was conducted to determine the effect of different water management schemes on the growth and yield of green super rice 5 (GSR 5) genotype. The experiment was laid out using Randomized Complete Block Design (RCBD) to test the following treatments: Treatment 1 – Alternate Wetting and Drying (AWD); Treatment 2 – Continuous Flooding (CF); and Treatment 3 – Field Capacity (FC).The GSR 5 subjected to different water management schemes revealed comparable data in almost all agronomic and yield traits as it exhibited no significant differences in terms of number of days to 50% flowering, number of days to maturity, height at maturity (cm), number of productive tillers, panicle length (cm), filled and unfilled grains, biomass yield (g), weight of 1000 grains (g) and grain yield per hectare. However, in terms of root length, Treatment 1 significantly obtained the longest. Even with insignificant variations among the three water management schemes, alternate wetting and drying revealed better results compared with the other treatments in most of the parameters considered. Moreover, the reduction in the frequency of water application in AWD scheme resulted to a significant decrease in the cost of irrigation without significant reduction in the yield. Hence, the application of AWD scheme is recommended for GSR 5 production.
