The different elements of climate have an effective impact on the nature and quality of cultivated crops in any region and this effect is reflected by determining the thermal, photovoltaic, and water requirements and the time of germination and growth for each crop, The results show that there is a difference in climatic conditions in each of the study stations within Anbar Governorate, and this variation is evident in the climatic elements affecting the growth and maturity of oily crops, especially the general average temperature and the maximum and minimum temperature rates, which increased in 2022 compared to the year 2000. In the shadow of the decrease in the amounts of rain from what it was in the past, this difference was reflected in the quantities of production between those years, as the output in the year 2000 was more than the amount of production in the year 2022 for all crops, so the amount of production for the Maize crop in the year 2000 was (22620) tons, while in the year 2022 (16450) tons, while the sunflower crop was (40.6) tons, while in the year 2022 (15.1) tons, and the cotton crop in the year 2000 was (57.6) tons, while the production reached in 2022 (11.1) tons, the sesame crop in the year 2000 (1873) and in the year 2022 (210.3) tons.
