Abstract

In order to investigate the effects of DEFICIT IRRIGATION management on RICE yield at transplanted (TP) farming a field experiment was conducted at RICE Research Institute (Mazandaran, Amol) during 2000-01 on RICE, Tarom variety. The treatments included seven levels of irrigation managements. The experiment was arranged in a randomized complete block design (RCBD) with three replications. Objectives of this study were improving WATER PRODUCTIVITY (WPI and WPI+p) and get reasonable yield. Results indicated that there was a more significant difference in yield between treatments (α≤0.01). Maximum PADDY YIELD was for T1 (whole submerged soil: 5 cm water) with 4373kg ha-1and minimum PADDY YIELD was for T7 (saturated soil during whole growth season) with 3943kg ha-1. Amounts of WPI+p and WPI for T7 were 6.1 and 7kg mm-1respectively. At T7 treatment with 42 percent reduction of water use, only 10 percent decreased paddy grain yield. Results showed that it is not necessary to maintain the RICE field submerged in whole growth period. Using this method it is possible to increase productivity of irrigated field and DEFICIT IRRIGATION method can be applied without noticeable yield reduction.
