| Egyptian what represents the most important winter crop and the bread produced from it is the important commodities for Egyptian people in daily food. Egypt imports about 9.95 million tons for facing the gap between consumption and production which is about 9.64 million tons in 2016. Subsidy represented at least 70% of the value of food subsidies which over 22.442 billion Egyptian pounds in 2016. The study aimed to measure the impact of the general equation for the climate factors (Maximum Temperature, minimum temperature, and the average relative humidity) in the growing months of wheat crop. The study also determined the relationship between climatic factor, the critical month, and the yield, by measuring the economic impacts of a climatic factor with the yield on the farm level and national level. The results from measuring the relationship between the yield of wheat and minimum temperature showed that each increase in minimum temperature with one degree leads to a decrease in the yield with 0.11 per feedan, with statistical significance, T calculated was -4.37, while determination coefficient indicated to around 42% of the changes in the yield due to the changes in minimum temperature in April. Results showed also there are some scenarios showed the effect of minimum temperature changing on the yield, which made effects on revenues and quantity and value of imports. Finally the study recommended the importance of collecting and analyzing climate data at the level of the districts, governorates and the republic, while making them available to researchers, Change the crop map of different crops in the light of changes in climatic factors or those expected to occur and Preparing programs to cultivate the varieties of crops that are resistant to heat tolerance and that the financing of these programs is sufficient to accelerate the emergence of expected new varie | ||||
