The growth of agricultural production was characterized for a long 
time by relative stagnation in Egypt due to the narrow agricultural area on 
the one hand, and the limited agricultural expansion into new lands on the 
other hand, due to the many problems facing such a policy, whether 
technical, administrative, or financing. As well as the spread of the 
phenomenon of fragmentation, land dispersion, and dwarfing of agricultural 
holdings, and the resulting shortcomings in the use of both agricultural 
mechanization and the full use of technology in the agricultural sector, and 
then a decrease in the productive efficiency of using agricultural resources, 
resulting in price imbalances, whether in the resource market and/or the 
product market.
The study aims to study the technical efficiency of agricultural resources 
used in growing the most important crops in the center of Dar es Salam, 
Sohag Governorate, through several sub-objectives, including:
1- Study the efficiency of exploiting economic resources by measuring some 
technical efficiency indicators for the most important crops in the research 
sample.
2- Estimating the production cost functions of the most important crops in 
the research sample.
To achieve the aforementioned research objectives, this study relied on the 
inductive method in economic analysis, and some statistical and standard 
analysis tools were applied. The study also relied on the efficiency analysis 
method of estimating production frontier functions, and the regression 
method was used in both its simple and multiple forms. This study relied on 
a multi-stage, stratified random sample of 200 farms, representing the 
various tenure categories of farmers in the center of Dar es Salaam, Sohag 
Governorate, and relied on published and unpublished secondary data 
obtained from data from the Central Agency for Public Mobilization and 
Statistics, as well as the Economic Affairs Sector affiliated with the Ministry 
of Agriculture, as well as some scientific books, references, research and 
studies
