Abstract

The use of pesticide and fertilizer has been very widespread in agricultural from the last five decade. Buildup of injurious chemical density in surface and groundwater resulted from poor management in irrigation and FERTIGATION in agricultural. The bad management in application of chemical fertilizers in agricultural is hazardous, therefore in order to increase the yield and reduced resources water contaminations, the irrigation and FERTIGATION management is essential. A research was conducted in an area of 32.1 ha under CENTER PIVOT IRRIGATION system (low pressure system) in order to determine the OPTIMAL irrigation depth assessment base on three different economic management strategies. The values of economical ratio (C) were determined 20.01, 3.21, and 1.13 for three different management strategies such as unlimited, limited fertilizer leaching, and limited environmental protection respectively. The results showed that the values of OPTIMAL irrigation depth for three irrigation water management strategies (assuming exponential distribution) were 8.32, 13.33, and 17.98 mm respectively.According to the obtained results of this research, an unlimited ECONOMIC MANAGEMENT STRATEGY is recommended under deficit irrigation water or draught conditions.
