ظاهرة الجفاف و أثرها على إنتاجية محصول القمح في محافظات (نينوى كركوك صلاح الدين)‎

Abstract EN

The drought Problem is one of the most important challenges Facing the world today and is one of the Consequences of Climate changes that the world is Facing today.

This problem has negative repercussions on agricultural production especially wheat crop.

This study, which was tagged as (drought phenomenon and its effect on wheat yield in Ninawa, Kirkuk, Salahuddin governorates) presented the problem of the study and then assumed initial solutions and then the importance of the research as well as the definition of drought and its types (F.

A.

O) to Calculate the resulting evaporation which is the basis for Calculating the draught equation (D).

statistical analysis was adopted where drought coefficient was Considered as an independent Factor, while productivity was Considered as dependent factor.

The results showed that there was a strong (negative) Correlation between drought and wheat yield.

The Correlation Coefficient was (- 0.722, - 0.770, - 0.610) in stations (Nineveh, Kirkuk, and Baiji) respectively.
