Deficit The study of ECO-physiological aspects and influence of water Dem2-03-709 on growth and development of mungbean cultivars

Ground plants especially agricultural plants always are under conditions of environmental stresses like drought (dry year) and become injured. Study on diversity of drought tolerant devices can present useful knowledge about different kinds of adaptabilities. Amongst environmental stresses, drought stress is one of the most important factors that injures agricultural plants and decreases their function. Drought and water stress are most important factors decrease growth and development of agricultural (agricultural) plants at semi-humid, arid and medium regions around the world. In this case, possibility of expanding agricultural lands is too low and increasing population needs food preparation. Iran is one of the countries that the vast part of it is located under special condition and located at arid and semi-arid weather; rate of rains and ground water resources in Iran is going to decrease. Therefore, we should search and follow appropriate solutions and correct agricultural choices and we can prevent from decreasing agricultural products at arid years. So, manner of water management in the farm is most effective factor on function of agricultural productions
