Abstract:

A study was conducted with the objective to study the comparative performance of rice in terms of growth under continuous submergence and Alternate wetting and drying (AWD) water management practice. The treatments consisted of continuous submergence throughout the crop growing season besides AWD irrigation regimes with two ponded water depths of 3 and 5 cm and drop in ponded water levels in field water tube below ground level to 5, 10 and 15 cm depth. The eight treatments were laid out in randomized block design with three replications. Maintenance of Continuous Submergence depth of 3-cm from transplanting to PI and 5-cm from PI to PM (I1) registered significantly superior performance in terms of plant height (106.8 and 107.8 cm ), tiller production (17.9 and 19.5 hill-1), LAI ( 4.15 and 4.16) and dry matter production (54.04 and 56.37 g hill-1) in 2013 and 2014, respectively over rest of the irrigation regimes except that it was on par with I2 (Flooding to a water depth of 3-cm between 15 DAT to PM as and when ponded water level drops to 5-cm BGL in field water tube), I5 (Flooding to a water depth of 5-cm between 15 DAT to PM as and when ponded water level drops to 5-cm BGL in field water tube) and I6 (Flooding to a water depth of 5-cm between 15 DAT to PM as and when ponded water level drops to 10-cm BGL in field water tube). Whereas, I4 (Flooding to a water depth of 3-cm between 15 DAT to PM as and when ponded water level drops to 15-cm BGL in field water tube), I7 (Flooding to a water depth of 5-cm between 15 DAT to PM as and when ponded water level drops to 15-cm BGL in field water tube) and I8 (Flooding to a water depth of 3-cm between 15 DAT to PI and 5-cm between PI to PM as and when ponded water level drops to 15-cm BGL in field water tube) registered significantly inferior performance in terms of plant height, tiller production, LAI and dry matter production. So it can be concluded that rice crop can be successfully grown by adopting an appropriate AWD irrigation regime under sandy clay soils of Rajendranagar, Telangana State.
