Abstract
3 Abstract: Two field experiments were conducted at the Rice Research and Training Center (RRTC), Sakha, Kafr-El Sheikh Governorate, Egypt during summer seasons 2009 and 2010 to study the effect of nitrogen fertilizer and seedling age on Giza 178, H1 and Sakha 101. Four nitrogen levels were used (0, 55, 110 and 165 kg N/ha) and three seedling age i.e. 20, 30 and 40 days from sowing. The results indicated that number of tillers/hill, days from sowing up to panicle initiation, heading dates, leaf area index, leaf area ratio, chlorophyll content,1000-grain weight, panicles length, agronomic efficiency, utilization efficiency and grain yield (ton/ha) were increased by increasing nitrogen levels up to 165kg N /ha. The 20 days seedling age recorded the highest values of each studied attributes. Sakha 101 variety surpassed than other varieties for all studied characters. The interaction between H1 hybrid rice variety and application of 164 kg N/ha gave the highest value of utilization efficiency (kg/ha), agronomic efficiency, leaf area ratio. Seedling age (20 days from sowing) with H1 hybrid rice gave the highest value of utilization efficiency (kg/ha), agronomic efficiency, leaf area ratio, while H1 hybrid rice at 20 days age of seedling without nitrogen application gave the lowest value of utilization efficiency (kg/ha), agronomic efficiency, leaf area ratio.
