The State strives to develop the agricultural sector through four axes: horizontal expansion, increasing the vertical productivity of the unit of area and intensification of crop and production of economic crops for export. The problem of research is that the modest rates of agricultural investment. The research relied on descriptive and quantitative analysis, The most important research results were the estimation of the most important indicators of agricultural development in Egypt, such as: Agricultural Investment Rate: The engineering average reached about 0.07 billion pounds during the period of study, - The rate of agricultural intensification, where the engineering average was about 1.77 million feddans during the study period, - The share of agricultural worker of the cultivated area was the engineering average About 1.54million feddans during the study period, - the agricultural worker's share of the cropping area, the engineering average reached about 2.63 million the agricultural average reached about 1398.8 million workers during the study period. The productivity of the agricultural worker reached about 10807.7, with an engineering average of about 20334.65 million workers during the study period. On agricultural investment, where the engineering medium reached about 9.11 billion The measurement of the determinants of agricultural development in Egypt using the Nerloff model and the estimate of the partial adjustment coefficient (λ) was found to be about 0.951 indicating that a large part of the gap between the actual and desired situation is closed within one time period. The most important factors affecting agricultural development through the index of average per capita agricultural income (y) was agricultural credit, Agricultural exports, Agricultural taxes.
