Abstract
Two field experiments were conducted at the Experimental Farm of Etai El- Baroud Agricultural Research Station, Behaira Governorate, Agriculture Research Center (ARC), Egypt during 2015 and 2016 summer seasons to evaluate the performance of three rice cultivars namely Giza 179, Sakha 105 and Sakha 106. A split plot design with three replicates was used. The main plots were devoted to rice cultivars and the sub plots were occupied by different nitrogen treatments T1 (60 Kg N/fed), T2 (2 Tons rice husk + 40 Kg N/fed), T3 (2 tons rice husk + 2 tons rice straw + 40 Kg N/fed) and T4 (2 tons rice straw + 40 Kg N/fed). The results showed significant differences between cultivars for most studied characters. Comparison between means showed that in both study seasons rice cultivar Giza 179 gave the highest values for number of panicles/m2 , grain yield , broken and grain shape while, lowest values for 1000 grain weight, hulling, grain length, grain width and protein content. Moreover, Sakha 105 rice cultivar showed highest values for grain length, grain width, protein content % and water uptake. Sakha 106 rice cultivar showed superiority for 1000 grain weight, hulling and milling. Furthermore, applying 2 ton rice husk + 2 ton rice straw + 40 Kg N/fed showed superiority for number of panicles/m2 , number of filled grains/panicle, 1000 grain weight, grain yield, hulling, milling and protein content. Interaction between rice cultivars and nitrogen treatments in both study seasons showed the highest values for number of panicles/m2, grain yield and milling were noticed with Giza 179 rice cultivar and applying 2 tons rice husk +2 tons rice straw +40 Kg N/fed. Moreover, the highest values for number of filled grains/panicle, 1000 grain weight and hulling were recognized with Sakha 106 rice cultivar and applying 2 tons rice husk +2 tons rice straw +40 Kg N/fed.
