Description
Summary:Wheat is the most important world crop grown on more of the world's acreage than any other crop in terms of feeding of human. Water and nitrogen (N) are the main limiting factors affecting agricultural production in arid and semiarid regions. Drought originates from deficiency of precipitation which effecting wide areas for temporary periods. However, it is not defined as only water scarcity but also other climate factors such as high temperature and low relative humidity. Effects of drought depend on the phenological stage of the wheat plants. According to a study carried out in this area, the rates of 70 kg N/ha under non-irrigation conditions and 150-170 kg N/ha under irrigated conditions are needed as the economic maximum fertilizer nitrogen for wheat. In this article, it discussed on water and nitrogen relationships, effects of drought under both irrigated and rainfall conditions and the equations showing economically amount of nitrogen for wheat in South-eastern Anatolia Region of Turkey.
