Abstract
A field study was conducted entitled with “Standardization of Alternate Wetting and Drying (AWD) method of water management in low land rice (Oryza sativa (L.) for up scaling in command outlets”. The treatments consisted of continuous submergence throughout the crop growing season besides AWD irrigation regimes with two pond water depths of 3 and 5 cm and drop in pond 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. Continuous Submergence (CS) registered higher nitrogen uptake 20.78, 45.52, 64.05 and 85.36 kg ha-1 at 30, 60, 90 DAT and at harvest, respectively which resulted it recorded significantly higher SPAD chlorophyll meter (SCMR) readings (42.74, 42.78) and Leaf Color Chart (LCC) ratings (3.83, 3.94) over rest of the irrigation regimes except that it was on par with Flooding to a water depth of 3-cm between 15 DAT to PM as and when pond water level drops to 5-cm Below ground level (BGL) in field water tube (39.40, 39.59), (3.59, 3.51), Flooding to a water depth of 5-cm between 15 DAT to PM as and when pond water level drops to 5-cm BGL in field water tube (41.21, 41.78), (3.73, 3.74) and Flooding to a water depth of 5-cm between 15 DAT to PM as and when pond water level drops to 10-cm BGL in field water tube (40.04, 40.83), (3.69, 3.52).
