Iran is one of the dry regions of the world and is currently facing a severe water crisis.Therefore, more attention should be paid to the optimal use of water and the protection of water resources.which is very important in providing food for the residents of our country. Also, planting time is one of the most important dates in the agricultural calendar of a plant, because other agricultural activities are determined accordingly.One of the newest models that has the ability to simulate the rate of growth and performance of various agricultural and horticultural crops in relation to the amount of water consumed is called the Aquacrop model. The purpose of this research is to simulate and determine the most appropriate date for planting Sirvan blue wheat in South Khorasan province using the AquaCrop plant simulator model.For this purpose, daily climate data as well as other environmental information from Birjand synoptic station have been used in a two-year period(1395-1396)and(1396-1397)and the efficiency of the model has been evaluated using field data. After ensuring the effectiveness of the model, 3 treatments with 3 irrigation levels of 75, 100 and 125% of water supply, with two levels of salinity(6 and 1.6 dS/m)were simulated on the planting dates of November 1st to December 10th. Among the input dates to the model, the date with the highest yield was selected as the best planting date for the study area.The results of the research showed that the suitable planting date is different for each climate, and on the other hand, the yield of wheat is very sensitive to the characteristics of each region in choosing the type of variety and changing the planting date.Therefore, in this research, the best planting date of Sirvan wheat cultivar for the studied area was the second half of November, which is recommended.
