Abstract

To prevent water loss and to maximize water productivity by hybrid rice using desirable water saving irrigation regimes, four rice hybrids were tested in three irrigation regimes (Normal flooded, 50% less than normal and 75% less than normal) during 2019 at Crop Sciences Institute (CSI), National Agriculture Research Center, Islamabad (latitude 33° 42 N' and longitude 73° 10' E)
Pakistan. The experiment was conducted in RCB design with four rice hybrids and three irrigation treatments and
three replications. Pooled analysis of variance depicted significant differences among the tested hybrids for most
of the traits except thousand grain weight and canopy temperature. Plant height and number of tillers per plant
revealed a negative trend when irrigation was reduced from normal level, however, this reduction in irrigation caused
an increase in the number of grains per panicle, thousand
