Abstract: Present study was carried out to evaluate the effect of seed priming with zinc sulphate and aerobic rice cultivar on chlorophyll content, yield and water productivity under irrigation regime at Palli Siksha Bhavana (Institute of Agriculture) Farm, Sriniketan, Birbhum, West Bengal. Results revealed that total chlorophyll content, relative leaf water content, panicle length and water productivity was highest with irrigation regime at 100% of CPE (I100) and irrigation regime at 150% of CPE (I150) over irrigation regime at 75% of CPE (I75). Among the cultivars, CR-Dhan 201 recorded higher total chlorophyll content, relative leaf water content, grain yield and water productivity as compared to CR-Dhan 204 and Pyari. Zinc sulphate hepta hydrate application through seed priming at 0.3% recorded significantly higher total chlorophyll content, relative leaf water content, panicle length, grain yield and water productivity. Thus irrigation at 100% of CPE (I100) in combination with seed priming with ZnSO4 @ 0.3% and CR-Dhan 201 may be adopted for aerobic rice cultivation in lateritic soil of West Bengal.
