The research aims to evaluate cultivating sugar beet crop in Egypt and constraints faced in areas of production concentration.
Research findings obtained from the estimated production functions for sugar beet grown in Kafr El-Shiekh Governorate in 2007 indicate that labor, azotes fertilizer, phosphate fertilizer, and seeds represent the variables that have statistically significant impacts on sugar beet productivity/feddan. As for the first land-holding category, the factors of significant impact include labor, azotes fertilizer, and seeds, whilst factors of significant impact on productivity/feddan for the second land-holding category include labor, phosphate fertilizer, and seeds. Finally, the estimated model for the third land-holding category indicate that the factors that have a significant impact on sugar beet production for this category include labor, machine work, and phosphate fertilizer.
The summation of production elasticities for the factors affecting sugar beet productivity/feddan at both the level of the total sample and the level of land-holding categories indicate that it is positive and less than one, which means that production inputs are used according to the economics of the second stage of the production function.
On the other hand, the estimated cost functions for sugar beet production indicate that the optimum volumes of production that minimize the costs at the level of the total sample and the three land-holding categories are estimated at 19.926 tons/fed, 18.384 tons/fed, 18.75 tons/fed, and 21.577 tons/fed respectively. In addition, results indicate that the volumes of production that maximize the profits at the level of the total sample and the three land-holding categories are estimated at 28.357 tons/fed, 25.11 tons/fed, 24.75 tons/fed, and 29.67 tons/fed respectively.
