الموازنة المائية المناخية بين الإستهلاك المائي لمحصولي القمح و الرز و بين كمية الأمطار الساقطة في العراق

الملخص EN

The study aims at calculating the climate water balance between the amount of water consumption of wheat and rice crops and the amount of falling rain in the seasons of cultivation, from the period of germination to maturity in Iraq.

It is based on the data of 17 climatic stations distributed in the governorates of Iraq.

The results proved that the validity of the third hypothesis, which indicates that in the case of water surplus or deficit, they have a (effective) effect on the water consumption of wheat and rice crops in the study area.

A surplus of water in the mountainous region in relation to the wheat crop makes its Rainfed agriculture guaranteed in this region.

Note that the water surplus gradually decreases in the crowned region, until it reaches the deficit stage in central and southern Iraq.

The existence of a complete water deficit in all regions of Iraq during the rice crop season, with clear differences in the severity of the deficit, gradually is increasing from the north to the south.
