تأثير الحرارة و الأمطار في إنتاج محصولي القمح و الشعير في محافظة نينوى

الملخص EN

The research is summarized by revealing the influential relationship between temperatures and precipitation on one side and the quantities of production for wheat and barley crops in Nineveh Governorate on the other hand.

Thus, the causes of fluctuations in production quantities between agricultural seasons can be explained within the time period extending from the agricultural season (2004- 2005) to the season (2013-2014) in the study area.

The climate of the study area was studied through the data of several climatic stations, and it was found that its components (temperature, rainfall) have a significant impact on the productivity of wheat and barley crops in a different way from one region to another within the governorate.

The temperature affected the length of the growing period and the type of crop.

The temperature prevailing in the growing season was closer to the preferred temperature during the growth period of the two crops.

The rates of rainfall affected the production quantities in a different way because most of the farmers in the study area depend on rain-fed agriculture or dry agriculture, and thus the difference in the rates of rainfall from one region to another, which led to fluctuations in the quantities of production, in addition to that there is irrigation agriculture for the wheat and barley crops, but in a small way compared with the rain-fed agriculture, this is because the study area is located within the semi-guaranteed rain areas according to the rain distribution map in Iraq.

On the other hand, the study area is characterized by flat topography, in which there are no rugged lands, and most of its lands are plain (with little slope), which facilitated the use of agricultural machinery and equipment during the cultivation and harvest periods.
