Determination of best rice cultivar under stress caused by different irrigation managements
Abstract:   (3886 Views)

In order to determine the optimized management of irrigation and the most suitable cultivar in different conditions of irrigation, an experiment was conducted as split-plot based on complete randomized blocks design with three replications in Rice Research Institute of Iran in spring 2006. Main plots were five irrigation managements: constant saturated irrigation, irrigation after disappearance of water from surface, alternative irrigation with 5, 8 and 11 days, and sub-plots were three rice cultivars (Bahar, Dorfak and Ali Kazemi). The different between irrigation treatments and the cultivars under study was significant in term all studied traits except the exertion of panicle length and the number of branches. Bahar cultivar had the highest tiller number, biomass, biological and economical yield, yield harvest index, and the shortest height. The difference between the constant saturated irrigation and days after disappearance of irrigation from surface was not significant. In addition, Bahar cultivar yield showed declining trend with the increase of water stress. Bahar cultivar under of water stress conditions had the highest yield which indicated the high potential of this cultivar in dry conditions. Therefore, planting it can be recommended for achieving high yield in reigns with less water if this cultivar was not available. Dorfak cultivar can be used as a cultivar with highest yield compared with Ali Kazemi.
