| Abstract | ||||
| Two field experiments were carried out at the Agricultural Experimental farm of Faculty of Agriculture; Suez Canal University; Ismailia Governorate, Egypt during two winter seasons of 2012/13 and 2013/14. These experiments aimed to study the effect of regimes, rates of nitrogen fertilization (50.75 and 100 kg/fed) and two wheat varieties (Sakha 94 and Sedes 12) and their interaction on plant growth characteristics. This experimental farm is located at Longitude 30 o 58\\ and Latitude 32 o 23\\ at 13 meter above sea level. The texture of experimental site was sandy soil. Split–split plot design with three replications was followed. Exposure wheat plants to drought stress treatment at tillering or heading stages significantly decreased each of total chlorophyll, carotenoid pigments, plant height, dry weight of biomass above ground/ plant, flag leaf area, leaf area index and crop growth rate at the two growing seasons comparing to control treatment without skipping any irrigation. Meanwhile, proline content was decreased by skipping irrigations at tillering and heading stages. Increasing nitrogen fertilizer up to 100 kg N/fed led to increase all traits under studying during two growing seasons. Wheat cultivar Sakha 94 surpassed Sedes 12 in all traits. Flag leaf area, total chlorophyll and proline contents were affected significantly by interaction between the studied factors. | ||||
