Abstract

A study was undertaken at Regional Research and Technology Transfer Station, Chiplima, Sambalpur, Odisha on rice var. khandagiri during summer season of 2011, 2012 and 2013 in split plot design with three irrigation schedule (main plots) and three date of transplanting (sub plots). Experimental results indicated that the irrigation schedules at one day after disappearance of ponded water (DPW) recorded the highest grain yield of 3.07 t ha-1 which was at par with irrigation schedule at 2-days after DPW. Both the irrigation schedules were significantly superior over 3-days after DPW. The date of transplanting on 15th January produced highest grain yield (3.11t ha-1) which was significantly superior to other transplanting date on 30th January and 15th February. Highest water use efficiency was observed with irrigation schedule at 3-days after DPW (43.7 kg ha-cm-1) and transplanting on 15th January(43.2 kg
ha-cm-1). The treatment that received irrigation schedule at 1-day after DPW registered the highest dry matter heat use efficiency (3.62 kg ha-10C day-1) and grain yield heat use efficiency(1.84 kg ha-10C day-1).The transplanting on 15th January produced highest dry matter heat use efficiency(3.83 kg ha-10C day-1) and grain yield heat use efficiency(2.05 kg ha-10C day-1) which was significantly superior to other transplanting dates of 30th January and 15th February.
