Abstract
Two field experiments were conducted at the Experimental Farm of Rice Research and Training Center (RRTC),Sakha, Kafr el-sheikh, Egypt during 2014 and 2015 seasons. The objective of this investigation was aimed to study the response of Egyptian hybrid rice one cultivar (SK 2034 H) to times of nitrogen fertilization and foliar spraying of ascobien compound. The nitrogen times of fertilization included four treatments i.e. Basal soil (B), Mid tillering (MT), panicle initiation (PI) and booting stage (BT). Foliar application of ascorbien compound at rate of 1.050 Kg/fed at two dates as follows, without ascorbien, spraying after transplanting by 25 days and at 25 and 45 days from transplanting. The main finding could be summarized as follows,1-Nitrogen fertilization splitting at rate of (69 Kg N/fed) at 17.25 Kg N/fed at B+ MT+ PI+ BT significantly maximize leaf area index, number of tillers /hill, number of filled grain/hill, 1000 grain weight and grain yield/fed, hulling, milling and broken rice percentage. 2- Foliar spraying of ascorbien compound twice at 25 and 45 days from transplanting significantly increased the previous studied traits as we mentioned before. 3- The interaction between times of nitrogen fertilization and foliar spraying of ascorbien compound significantly affected all the studied characters in this study. It could be concluded that splitting nitrogen at four equal doses (17.25 Kg N/fed) and foliar spraying of ascorbien compound at 25 and 45 days from transplanting of Egyptian hybrid rice one cultivar (SK 2034 H) was the recommended treatment to improve growth, yield components and grain quality and produced the greatest grain yield (4.48 t/fed) under the environment condition of Sakha Kafr El-sheikh.
