Abstract

      This research aimed to analyze geographically the climate change in of in the cotton crop change province in Wassit. It shows climatic changes on climatic elements (actual solar brightness, minimum and maximum temperature) and its effects on changing the cotton yield and its reflection in wassit province. And the extent of the impact of those changes in the area, yield, and yield of the crop.  Relied on data for three climatic stations (Baghdad, AL-Diwaniyah, AL-Hayy) for the period (1985-2017).                                                        

     Determine the calculation of the trend coefficient, and the rate of annual change during the research period for The average of the different climatic elements, which was in the form of (annual annual cycles), and show the direction of the actual solar brightness in all study stations towards the decline and direction of the lower and upper temperatures towards height, research found that the changes that took place in the cotton, some positive and the other negative crop.
