Abstract
This research was carried out at the Administration of Natural Resources Research, General Commission for Scientific Agricultural Research GCSAR, in 2018; it is considered a computer software with the first version, which calculates the quantity of water requirement for optimal plant growth without water stress according to the climatic data which was calculated for the specific area, taking into consideration no water waste, according to the proper irrigation method of the plant based on the climate data which is included in the program database. The monthly modified crop coefficients were confirmed which depended on the phonological stages of crops and trees and the results of long term of researchs that were carried out at the irrigation research stations of GCSAR, which distributed to cover the seven water basins in Syria. This program calculates the monthly plant water requirements for crops, vegetables, and trees according to Penman Montieth equation which estimates the reference evapotranspiration taking into consideration the irrigation efficiency and coefficient of reduction according to the irrigation method. This program aimed to be a guide software for estimating plant water requirements and this software is considered as a result of a research project which was supported by (GCSAR) reflecting its efforts to rationalize uses of irrigation water and improving water use efficiency especially in arid and semi-arid regions, which already had scarce in its water resources.
Keywords: Software, Water requirement, Evapotranspiration, Crop coefficient.
