)Climate and its effect on water consumption of sesame crop in the middle Euphrates governorates(

Abstract

   Climate is one of the most important factors that directly and indirectly affect plant life, as the influence of the prevailing climatic conditions on the distribution of the main groups of plants on the surface of the globe appears stronger than the influence of any other factor of nature. Climate does not work only through its elements such as heat and rain And light and wind directly affect the spatial distribution of plants, but also appear indirectly on plant life in the process of weathering of the rocks of the earth's crust, the formation of soil and the processes of the layers of its sector, and in the mineral and organic components.
