A field experiment was conducted during kharif 2003 and 2004 at College farm, College of Agriculture, Rajendranagar, Hyderabad to study the influence of different dates of sowing on plant water relations and grain yield of aerobic rice. Higher grain yield, relative leaf water content, lower leaf temperature and leaf diffusion resistance (LDR) were recorded on 16 and 26 June sown crop. Grain yield had significant positive correlation with RLWC (0.72**), and negative correlation with leaf temperature (0.67**) and leaf diffusion resistance (0.70**) recorded at 45 DAE in aerobic rice.
