Drought is a major problem for plant breeding in the country during dry years. This, in parallel with the increase in the technical capabilities of agriculture, has put more emphasis on overcoming the drought phenomenon. For this purpose, efforts have been made both in the development of relevant technical concepts and in the development of appropriate methodologies and technologies. The most important activity in this direction is the redistribution of water resources mostly over time. The report presents some aspects of overcoming the effects of drought by optimizing the use of water resources.
