أثر الموازنة المائية المناخية في تحديد الاحتياجات المائية لنماذج بعض المحاصيل الزراعية في محافظة المثنى

Abstract EN

Knowing and analyzing the climatic water balance of the study area is useful in determining the periods of water surplus and deficit in the agricultural side, depending on the monthly rates of maximum and minimum temperatures, the average wind speed, the number of actual and theoretical sun hours, and the relative humidity.

The application of the (CROP WAT8.0) program gives a methodology in estimating needs Hydroponics for agricultural crops, depending on the climatic data and the values of the yield factor, contribute to determining the characteristics of the area, and thus estimating the amount of water using mathematical methods to calculate the net and total irrigation needs which leads to determining the amount of the water ration.

This helps reduce the imbalance between the need for water and the availability of it to plan the optimal management of irrigation water and evaluate production under changing rain conditions.
