Egypt seeks to achieve development in the agricultural sector within its development plans that includes increasing production, raising the levels of self sufficiency and achieving a surplus of goods that have a comparative advantage, through agricultural development strategies that started since the early eighties, the strategy of the nineties and the strategy of agricultural development (2009- 2030) To complete the strategy of 2004-2017, however, the leading role of agriculture in economic development has declined in the last quarter of a century, as the contribution of agricultural output to the national product decreased from about 22.52% in 1998 to about 16.55% in 2000 then To about 11.49% in 2017, which indicates the decline in the role of the agricultural sector and that the reform policy package in the agricultural sector did not achieve the desired results from it. Therefore, the research aimed to identify the efficiency of the development performance of the agricultural sector during the period (1998-2017), through studying the development The economic growth rate of the agricultural sector in Egypt, estimation of indicators of the efficiency of both agricultural investments, agricultural foreign trade, agricultural labor force. Where the research relied on descriptive and quantitative analysis methods, through the use of simple regression models in the logarithmic half image to estimate general time trend models, in addition to some indicators of the efficiency of both agricultural investment, agricultural foreign trade and the agricultural workforce), the research has reached the following results: 1- The agricultural sector has gone through periods of economic stagnation during the years (2000, 2003, 2004, 2008, 2011, 2017), while it has experienced periods of economic expansion during the rest of the study years. 2- With regard to indicators of agricultural investment efficiency at fixed prices during the study period, it was found that the employment factor reached a maximum of about 0.238 pounds in 1999, and also reached below 0.041 pounds in 2011 during the study period. The significance of the estimated model was not statistically confirmed, and the annual investment rate decreased, with an annual rate of decrease of about 7.3%. Statistical confirmation of the estimated model was significant. 3- With regard to indicators of agricultural foreign trade efficiency during the study period, it has been shown that the agricultural export strength index and the degree of agricultural openness and the annual agricultural coverage rate have increased at an annual increase rate of about 9.7%, 5.9% and 5.2% for each of them, respectively. Statistically, the morale of the model estimated for them 4- With regard to indicators of agricultural labor efficiency during the study period, it has been shown to increase the value of the productivity of the agricultural worker annually with an annual increase rate of about 2.2%. Estimated model significance. Accordingly, the research recommends the necessity of paying attention to the agricultural sector through increasing the volume of investments directed to this sector, developing agricultural exports and raising the efficiency of agricultural labor.
