In order to evaluate the effects of rice transplanting cultivation on furrow and different deficit irrigation management on yield and yield components of rice (Shiroodi Cultivar), an experiment was conducted at Rice Research Institute (Mazandaran, Amol) in 2013. The research had done as randomized complete block design involving five irrigation treatments with three replications. Treatments were irrigation managements including T1 (permanent irrigation throughout the growth period), T2 (irrigation a day after the disappearance of surface water) T3 (irrigation three days after the disappearance of surface water), T4 (irrigation four days after the disappearance of surface water), T5 (permanently saturated soil throughout the growing period). Results of ANOVA indicated that different irrigation managements had significant difference (P<0/01) in terms of panicle length, filled and unfilled grains and paddy yield. According to the results, there was not significant difference between T1 (5975 kg.ha-1) and T5 (5850 kg.ha-1) irrigation management and the least performance management of T4 with 28% lower performance than the T1 treatment. Therefore, the best results have been continually saturated water management and irrigation management; T2, T3 and T4 were next in the rankings.
