Abstract
Two field exponents were conducted at Etai EL Baroud Agricultural Research Station Al Beheira governorate (Agricultural Research Center )Egypt in 2003 and 2004 seasons to emphasize the effective nitrogen level for eight rice cultivars ,i.e Giza 177,,Giza178, Giza182, Sakha 101,Sakha102, Sakha103,Sakha104 and Egyptian Yasmine . Five nitrogen levels were used (0,69,92, 115 and 138 kg/ha ) as urea form 46.5%Nin two split 2/3was added as basal and incorporated in the dry soil before flooding and 1/3 ,was added at 7 days before panicle initiation of each rice cultivar .Four seedling with 25 days old were transplanted in hill spaced 20x20 cm except Giza 177 that was transplanted with 15x15cm planting spacing .All cultural practices were applied as recommended for each cultivar . A split plot design with four replication was used , nitrogen levels were allocated in the main plots and rice cultivars were allocated in the sup- plots .main results indicated that increasing nitrogen levels up to 138 kg N /ha significantly increased number of days to heading ,plant height ,While 115 kg N /ha was adequate for yield and and its components ( number of productive tillers /hill, panicle weight ,number of filled grains / panicle ,straw and grain yield ,1000 grain weight ) and harvest index .Giza 178 , Sakha 101 and Egyptian Yasmine recorded the highest values in agronomic efficiency under 115 kg N /ha than the other rice cultivars . Giza 182 and Sakha 104 under 92 kg N/ha ,while Giza 177 ,Sakha 102 and Sakha 103under 69 kg N/ha . Data showed that ,a significant effect due to the interaction between nitrogen levels and rice cultivars on panicle weight and grain yield.
