Abstract
This study was conducted on three different locations in El-Kharga Oasis, New Valley Governorate, Egypt, using four genotypes of wheat (Okas, 6, 14 and Sakha 93) during two successful growth winter seasons of 2012/13 and 2013/14. The soils of the locations were irrigated with shallow groundwater of different salinity (2.0, 5.2 and 10.7 dS.m-1) for Loc1, Loc2 and Loc3 respectively. Nitrogen fertilizer was applied at rates of 288 Kg N/Ha and 360 Kg N/Ha of the recommended N doses (288 Kg/Ha). The obtained results indicated that increasing water salinity from 2 to 5.2 and 10.7 dS.m-1 decreased significantly (P<0.05) the grain and straw yields of wheat by 6.1 and 4.9% for loc2 and by 47.4 and 22.4% for Loc3compared with loc1 respectively. The results also show that genotype-6 was more salinity tolerant than variety Sakha 93, Okas and 14 genotypes. The application of 360 Kg N/Ha fertilizer was significant enhanced the grain and straw yields of wheat genotypes. The data also, show that fertilization of genotype-6 with 360 Kg N/Ha to result in greatest grain yield of wheat under saline conditions.
