Abstract
Abstract

Water resources management in agriculture is one of the main components of sustainable economic development and food security. In terms of growing season, crop plants are divided into two groups: spring and winter plants. Winter plants are generally called dryland crops. Dryland crops use winter rainfall to meet water needs. At the beginning of the growing season, several irrigation stages are recommended to provide soil moisture, and at the end of the growing season, supplementary irrigation is planned to fill the seeds. The production of dryland crops is less than the potential, but water productivity is higher. In this study, the issue of agricultural water transfer in the Handijan plain of Khuzestan province was first addressed in order to evaluate water resources for dryland cultivation, and then the optimal amounts of water required for dryland cultivation of four crops, wheat, barley, rapeseed, and lentils, were calculated. The results showed that the water crisis situation in the studied plain will be increasingly serious and the need for dryland cultivation and supplementary irrigation is recommended. In addition, in water deficit conditions, it is essential to reduce autumn irrigation and meet the plant's water needs during the stages of maximum plant coverage. Maximum plant coverage for the studied plants is from late March to mid-May. After this stage, the plant canopy gradually wears out and the final crop is harvested.
