Abstract:
Rice (Oryza sativa L) is the staple food for more than 70 % of India population. In upland rice, water stress causes serious yield loss of upland rice due to reduction in various physiological parameters. A pot experiment was carried out during February, 2014 using the Polyhouse to maintain physiological drought, and thereafter the nearby experimental field of the Department of Crop Physiology, AAU, Jorhat. Results revealed from the investigation that leaf area (0 to 10.7 %), RLWC (2.32 to 8.94 %) and total chlorophyll (1.24 to 6.86 %) were reduced significantly in the varieties under physiological drought condition as compared to irrigated one. It has been observed that varieties Inglongkiri, Sok langlu and Sovak performed well under moisture stress condition and have well adaptive physiological traits which can be used in growing different areas of Assam.
