Abstract
Abstract : A field experiment was carried out at the Rice Research station in Al-Mishkab of the Public Authority for Agricultural Research during the 2012 season, in order to study effect of irrigation on growth and yield of two cultivar of rice used design was split plot RCBD with three replicates operated extended irrigation (4,7,10) days the main plots while the cultivars (yasmine, Mashkab 2) occupied the sub plots Use it the way Alstal and aged 20 days were applied irrigation treatments after 17 days of Agriculture in the field permanent was measured amount of water Gauge meter was the high water during irrigation 10 -8 cm and the results showed superiority for irrigation every 4 days in most recipes growth and winning as it gave 4.78 tons / ha, while given for irrigation every 10 days less than the values and amounted to 3.53 tons / ha and cultivar surpassed Mchkab 2 in the amount of winning as it gave 4.41 tons / ha while gave the yield Yasmin 3.92 tons/ha outperformed a combination product Mchkab 2 under irrigation every 4 days by giving it the highest sum amounted to 5.17 tons / ha can be concluded that it is possible to use irrigation intervals up to 7 days in the case of the use of periods of more than 7 days there will be a negative impact on the characteristics of growth and winning and this is the aim of the present study carried out in the system SRI (System of Rice Intesification).
