Fresh and renewable water resources suitable for irrigation of agricultural crops are restricted to most arid and semiarid regions of the world and this limitation has been increasing with time and population growth. Field cultivation was performed in a split plot design with randomized complete block design with three replications. The main factor of four irrigation including every day waterlogging, flooding three-day interval irrigation, drip irrigation with plastic wrap on a plot with two-day and two-day drip irrigation are without coverage. The sub-factor consisted of two rice varieties. Analysis of variance showed that the interaction between rice cultivars and irrigation method had significant effect on panicle number, 1000- grain weight and grain yield. The lowest average number of panicles per surface was obtained by daily irrigation method of waterlogging and Champa cultivar.
