This research aimed at the studying of total production of some
agricultural crops in Oakahlia governorate. The investigated crops are Wheat,
Beans, Winter Onion, Cotton, Summer Rice, Summer Maize, Summer
Potatoes and Summer Tomatoes. The present study is concemed also with
studying different factors affecting the cultivated area such as real Agricultural
prices real production costs, and Analysis of variance (ANOVA) for
comparing Regression coefficients and economic factors affecting the
investigated crops. Results of this research are indicating that there are
statistically significant differences between the development of both total
production and production costs for all previous crops during the period (1987
-2000). In addition to the increasing of production, there are exogenous
variables that affect on increasing production costs such as general level of
prices of inputs and labour wages. Changes of Agricultural prices are not consistent with changes in production costs for Rice, Potatoes and Tomatoes in Summer Season .
