Abstract
The research problem was the low productive efficiency of using resources and production elements used in growing rice, especially new varieties. Therefore, this research mainly aimed to identify the most important varieties of rice crop grown in Egypt, and to achieve this basic goal, this required achieving a set of sub-objectives, the most important of which is shedding light on the current situation of the rice crop in Egypt, and estimating some indicators of the productive efficiency of this crop. In the study sample, as well as identifying some productive and economic indicators for comparison between some cultivated varieties. In achieving its objectives, the research relied on descriptive and quantitative analysis methods, where general time trend equations, production functions, cost functions, and some economic indicators were used to compare the types in the study sample. The study relied on secondary data and primary data through questionnaire forms, which It was obtained from a sample of rice crops grown during the 2021/2022 season. Production functions were estimated for four varieties of rice. These varieties are Giza 177, Sakha 108, Sakha Super 300, and Sakha 104 in order to obtain standards of production efficiency. The significance of the production functions of these varieties was shown at the probability level of 0.01. By estimating the cost functions for the different varieties, it was found that the volume of production that has the lowest costs for the Giza 177 variety is estimated at about 3.4 tons, and this volume was achieved by 65% of the farmers of this variety in the study sample. As for the Sakha Super 300 variety, it was found that the optimal production volume that has the lowest costs is estimated at about 3.6 tons. All farmers in the study sample achieved this size. For the Sakha Sakha 104 variety, it was found that the optimal production volume that minimizes costs is estimated at approximately 2,743 tons. All farmers in the study sample achieved this size. As for the problems facing rice production in Egypt, these problems were divided into production problems, marketing problems, and problems related to irrigation water. These problems were arranged according to their priority according to their relative importance to their averages based on the opinions of the farmers in the study sample, using the L.S.D test, meaning least significant difference. The analysis of production problems revealed that they occupied five ranks, while marketing problems occupied three ranks, and problems related to irrigation water occupied only two ranks.
