| Abstract | ||||
| Models can be used for such a purposes to enable rapid and extensive condition testing. The current study is carried out to adaption mathematical model called KATENA to calculate the irrigation requirements under Egyptian conditions. Model use input data about climate, soil and plant parameters. Our study specified in metrological information for five stations in Egypt for 10 years and five kinds of fruit trees. By calculating the irrigation rate using different values of soil moisture content in the period of vegetation and non-vegetation show that the best value of pre-irrigation humidity are 0.65 and 0.75 and the optimum is 0.82%. | ||||
