ملخص المقالة :
Calculating the amount of effective rainfall as one of the water supply sources required for wheat cultivation is one of the basic study measures that can be used in the relevant planning. Therefore, identifying and applying a suitable method for estimating effective rainfall, especially in rainfed cultivation, is doubly important. In this study, various methods of determining effective rainfall were evaluated, including: US Department of Agriculture (SCS) Soil Conservation Service Methods, Reliable, Experimental, USDA) Percentage and Renfro Method, using SPSS software and by testing. Duncan's statistics are given in the city of Isfahan for the cultivation of rainfed wheat. The results of this evaluation show that the Renfro method has not been accepted because it shows the effective rainfall values more than the rainfall itself. Reliable and experimental SCS methods and precipitation are more suitable for wet areas due to high negative values (zero). The results show that the percentage method and USDA are more consistent with the amount of precipitation than other methods. Due to greater compliance with the average monthly rainfall, the best method for calculating effective rainfall in Isfahan and USDA for wheat was proposed.
