Evaluation of the agro-climatic regions for the barley crop in Iraq for the period(2010-2019)

Abstract

     Modern technologies are among the means that provide sufficient ability to find agricultural climatic regions for the barley crop in Iraq, based on (temperatures and the amount of precipitation). The study aimed to determine how to determine the agricultural climatic regions for the barley crop in Iraq, except for the Kurdistan region, and do its production quantities vary, and what is the role of agricultural policy? In developing the production of these crops by analyzing the spatial variation of temperature and amount of rain during the years of study and the appropriate temperatures and amount of rain for the crops during the stages of crop growth in those places, After analyzing the data, the study showed that there was a spatial variation in the average annual temperature of the study stations, ranging between (28.5 - 20.8) Celsius for each of the two stations (Mosul and Nasiriyah). The study also showed that there was a variation in the average annual amount of rainfall that ranged between (86-360). ) mm for both the Mosul and Ramadi stations, and after applying the logarithmic equation for the cultivated areas of the barley crop, the very high investment category for the barley crop appeared. The very high investment appeared in (Mosul) Governorate only, with a production rate of (851,219) tons, and the weak investment appeared in the Basra Governorate, with a production rate that reached (29021) tons.
