| Abstract | ||
| A field experiment was conducted during two successive seasons of 2004/2005 and 2005/2006 at Sids Agric. Res. Station BeniSuef to study the response of wheat yield (grain and straw yields), its components (number of spike/m2, number of grains/spike, grains weight/spike and 1000-grain weight), water consumptive use (WCU) and water use efficiency (WUE) to three levels of moisture regime (irrigation at 25-30, 50-55 and 75-80% of available soil moisture depletion) and nitrogen (50,75 and 100 kg N/fed.) under the prevailing conditions of the clayey Nile alluvial soil. The most important results could be summarized as follows: 1- Irrigating the soil at 50-55% depletion of the available water range (SMD) produced the greatest values of number of spike/m2, number of grains/spike, grains weight/spike, 1000-grain weight, grain yield and water use efficiency. 2- The highest values of straw yield and water consumptive use were recorded when plants subjected to irrigate at 25-30% SMD. 3- Increasing nitrogen levels up to 100 kg/fed. produced high increases in each of the studied plant characters as well as improved water consumptive use and water use efficiency. | ||
