Abstract

Water is the most important limiting factor for the development of agriculture in arid and semi-arid regions. In our country, in addition to water scarcity, which has caused problems for agricultural development, the lack of optimal use of extractive water has led to a lower yield. Therefore, considering the huge share of water use in agriculture and the low water productivity, it is considered necessary to select and apply methods for improving irrigation methods and optimizing water use in plants. Come In this research, irrigation management planning for wheat plant has been investigated using AquaCrop water productivity model at different stages of growth under Low irrigation and irrigation under stress conditions. Due to the fact that irrigation planning during the growth period always has a constant depth of water to the plant. Therefore, in this study, due to the water requirements of the plant at different times, the depth of irrigation water was changed. For this purpose, the required data of the model including climatic, vegetation data, applied irrigation amounts and wheat data were given to the model. Then, by changing the distance and depth of irrigation, water productivity and total dry matter of wheat were evaluated. The optimum selection for the product used in this research was obtained at 10 days intervals by application of different irrigation depths with a yield of 19. 19 kg / m3.
