Abstract

Water scarcity is considered as one of the important factors affecting the production of agricultural products. Using crop management models such as the AquaCrop model can be a useful tool for reviewing the options and the ability to examine them in different situations. This study was conducted to evaluate the AquaCrop model's ability to determine the Irrigation time of sugarcane plant and it’ s monitoring with water stress index in 2017 in cultivars and cultivars of sugarcane arranger cultivars in a R7-11 field with a total area of 25 hectares and a plant (new crop) Variety CP69-1062 was performed in south Ahwaz. The calibration was done to determine the accuracy of the model at the time of irrigation of the sugarcane plant, including an examination of the water stress index (CWSI) with a reddened thermometer. This calibration showed that the AquaCrop model has a relatively high simulation ability in determining the cannabis Irrigation time. The statistical analysis of the accuracy of the model in predicting the Irrigation time of the field with the actual field conditions was RMSE = 2. 0-day, d = 1. 0 and CRM= 0. 006. The irrigation scheduling of R7-11 farm with AquaCrop model was carried out with a total irrigation interval of 16. 6 rounds (from April to October 2017), the number of irrigation intervals with the number of irrigation intervals in plantations of CP69-1062 plant cultivars and dental industry Compared with the total irrigation intervals in the farms of 20. 8 rounds, the Khazaee was compared, it is observed that a R7-11 farm saved a quarter of the irrigation round in that year. The yield of this field yielded 128 tons per hectare and the average yield of planted plots of CP69-1062 varieties and cultivars were about 106. 63 tons per hectare. The quality of the R7-11 sugarcane syrup contains purity (PTY %) and the percentage of white sugar (RS %) of PTY = 90. 0 % RS = 11. 1 % and the average plant plantation varieties of CP69-1062 cultivars and cultivars, PTY = 88. 6 % and RS = 10. 8 % were obtained. The results of this study showed that considering the AquaCrop model has high accuracy, the use of this method to determine the Irrigation time compared to the current method (crop log) that is common in sugar cane companies in Khuzestan, both in terms of cost and in terms of its use in research projects.
