Abstract

Two field experiments were carried out in a private farm at Wadi El-Mollak region, Abo-Hammad District, Sharkia Governorate, during two winter seasons [2007/ 2008 and 2008/2009] in à reclamid sandy soil. This study aimed to invstigate the response of two wheat cultivars [ Giza168 and Sakha 93] to row spacing (12,15 and 18 cm between rows] and nitrogen fertilization levels [50, 70, 90 and 110 kgN/fad]. The split-split plot design with four replicates was followed. The important findings of this study could be summarized as follows:    Wheat cultivars under this study differed significantly in the most of their studied characters. Sakha 93 cv was superior than Giza 168 one in grain yield in t/fad. The obtained results showed that the average values of plant height (cm), number of tillers/ plant, leaf area cm2/plant, flag leaf area(cm2), spike length (cm), number of grains/ spike and 1000- grain weight(g) increased significantly with increasing row spacing from 12 to 18 cm, but mortality%, number of spikes/m2, grain yield and straw yield in t/ fad were decreased.    Growth characters, yield and its components were increased significantly due to increasing nitrogen fertilization level from 50 up to110kgN/fad, meantime the mortality of tillers% was decreased with increasing the applied N levels to90kgN/fad. The significant interaction effect between the studied factors indicated that. The highest grain yield could be scored, when the plants grown at 12cm row spacing received 90kgN/fad.
