Abstract
Two field experiments were conducted at the Experimental Farm of Etai El- Baroud Agricultural Research Station, Behaira Governorate, Agriculture Research Center (ARC), during 2012 and 2013 summer seasons to evaluate the response of three rice cultivars (Giza 178, Sakha 104 and Sakha 106) to nine different nitrogen sources i.e., (T1) Control, (T2) 75 % of the recommended mineral nitrogen, (T3) 50 % mineral + 25 % blue green algae (BGA), (T4) 50 % mineral + 25 % organic manure (OM), (T5) 25 % mineral + 25 % BGA + 25 % OM, (T6) 100 % of the recommended mineral N, (T7) 75 % mineral + 25 % BGA, (T8) 75 % mineral + 25 % OM and (T9) 50 % mineral + 25 % BGA + 25 % OM. A split plot design with three replications was used. The main plots were devoted to the three rice cultivars while mineral nitrogen, blue green algae (BGA) and organic manure (OM) combinations were arranged in the sub plots. The most important results are summarized as follows: (1) Varieties were highly significantly varied in all studied characters except leaf area index (LAI), number of filled grains and protein % in both seasons. (2) Applying 50 % mineral nitrogen combined with 25 % blue green algae and 25 % organic fertilizer showed the highest values for most studied characters in both seasons. (3) Grain yield was highly significant and positive correlated with LAI, number of panicles/m2, number of filled grains/panicle and 1000-grain weight with r- values of 0.90, 0.88, 0.90 and 0.94, respectively as averages of the two seasons.
