Özet:

Depending on the seasonal precipitation regime of long years in the Southeast Anatolia Region, droughts occur in agriculture due to irregularities in precipitation. Annual average the amount of precipitation is approximately 600 mm. With the temperature of the air, water in the dams except for its use, we lose about half of this precipitation with the most evaporation. In general, the use of water in our country is around 1500 tons per person per year. It is twice the water consumption rate per capita in the world. This is the water consumption in our country, indicates serious problems. However, if we look at water use again, the irrigated agricultural area in our country is around 20%. Therefore, in agricultural production using water effectively, adapted to arid and arid regions, tolerant to water stres, there is a need for product varieties with superior yields. Animal nutrition in our country is largely based on natural meadows and pastures, stubble and cereal straw, a few traditional forage crops such as sainfoin, common vetch and vetch are cultivated. In recent years, the obligation of the state to plant forage crops in semi-arid regions with the introduction of the plantation, an increase has been achieved in the cultivation areas, especially in our province. Stress, which is expressed by factors that affect the life of plants and cause different reactions in plants, it causes important physiological and metabolic changes in the plant, negatively affecting growth and development. Drought, in agricultural production causing huge yield losses although at the forefront of the factors reduces the quantity and quality of the product in the field. Drought, salinity, high or low temperature manifests itself as physical abiotic stress in the plant. The most important cause of water stress in the plant, in arid regions with annual precipitation below average values, it is associated with the negative impact of our land and water resources. Drought tolerant in the area alternative plant forage crops especially physiologically the water needs of the plant, irrigation method and suitable for efficient water use cultivation of varieties is important for the region.
