The response of rice (cv. Pant Dhan-4) to different planting dates and soil water regimes under upland conditions was studied in tarai region of Uttaranchal at the G. B. Pant University of Agriculture and Technology, Pantnagar . Delay in planting from15 June to 15 July decreased plant height (13 %), leaf area index (10 %), number of tillers (5 %), number of days to panicle initiation (6 to 8 days), 50 per cent flowering (12 to 15 days), maturity (6 to 7 days) and grain yield (5 to 15 %). Application of 7.5 cm irrigation water 3 days after disappearance from the plot reduced the number of tillers by 11 per cent and grain yield by 16 to 20 per cent over continuous submergence of 5.0 + 2.5 cm irrigation water. Crop maturity was delayed by 8 to 11 days due to change in soil water regimes from continuous submergence to rainfed conditions.
