The phenomenon of inflation is a problem inherent to the economies of different countries of the world, both developed and developing, and it is characterized by its rapid spread from one country to another, its strong growth from time to time, and the difficulty of controlling it. Demand for goods and services without being matched by an increase in real gross domestic product and thus an increase in prices. It also arises as a result of an increase in the costs of domestic and imported production factors, or as a result of an imbalance in some structural factors of the economic structure. The research aims to study the current situation of inflation in the agricultural sector, as well as to study its impact on the production costs of the most important field crops in Egypt, where the inflation rate reached the maximum amount of the total amount in 2020 at a rate of 42.5%, while it reached the minimum rate in 2009 at a rate of 8.% and an average of 22.5%. 20% during the period (2009-2020) and it was found that if the inflation rate of the total amount of agricultural production increased by 10%, this would lead to an increase in the value of land preparation, seeds and cultivation, fertilization, agricultural service, pest control, harvesting, crop transportation, public expenses , rent, costs without rent, rent costs for the wheat crop by 3.2%, 3.6%, 2.6%, 2.8%, 3%, 2.8%, 4.5%, 3.1%, 2.2%, 3.5%, and 3%, respectively. It was found that when the inflation rate of the total amount of agricultural production increased by 10%, this leads to an increase in the cost of preparing the land, seeds and cultivation, agricultural service, pest control, harvesting, crop transportation, general expenses, rent, costs without rent, irrigation, costs rent for maize crop by 2.9%, 2.9%, 3.4%, 3%, 5.7%, 3.9%, 2.7%, 2.7%, 2.1%, 2, 7% and 2.8%, respectively
