بعض المؤشرات الاقتصادية لإنتاج محصول البطاطس في ظل ظروف الزراعة التعاقدية وغير التعاقدية في نوباريا.

The marketing process is one of the main pillars on which any economic structure is built, as it is an integral part of the production process, and one of the most important challenges that Facing the agricultural product, contract farming, especially between small farmers and marketing companies, may be one of the most prominent solutions to avoid production problems. Also, agreeing on the prices of selling the crop in advance through contracting leads to reassuring the farmer to ensure his rights. Therefore, the research problem included the study of contract farming as a marketing system that ensures that farmers get remunerative prices to market their agricultural crops, and protects farmers from price fluctuations, with farmers not falling under the burden of merchants and moneylenders. Problems related to agricultural marketing still occupy the forefront among the problems that hinder the numerous and continuous attempts to increase returns. The research aims to study the economic indicators for the production of an acre of potato crop for the contract farming system compared to the non-contractual cultivation of Nobaria, The research was limited to contract farming related to manufacturing, and the Damont variety was chosen to conduct this study, and the research dealt with the relative importance of the variable costs items for the production of one Fedan of the summer potato crop, and it was found that the costs of both mechanical work and human labor are lower in the first group (contractors) than in the first group (contractors). The second group (non-contractors) increased by 258.4 and 323.6 pounds, respectively, Total production input costs ranked first with a rate of 69.31%, 65.56% of the average total variable costs in each of the first and second groups, respectively. By testing the significance of the difference using the (T) test, a significant difference was found at the level of 0.01, It also dealt with the economic efficiency of producing one acre of the summer potato crop (Diamont variety), and it was found that the average fixed costs decreased, and the average total costs in the first group, which amounted to 4.88 Thousand pound, 22.45 Thousand pound, respectively, compared to the same in the second group, which amounted to 5 Thousand pound, 22.35 Thousand pound Respectively, Increasing the average of variable costs, acre productivity, total revenue, net return, total marginal surplus, the ratio of total return to total costs, the return on the invested pound, and the profit margin ratio in the first group than in the second group, and by testing the significance of the difference between the average of the two groups using the (T) test for the difference between the two averages, it was found that there is a significant difference between them at the level of 0.01, which is due to the high price of the crop delivery to the factory in the first group, where the crop conforms to the required specifications and standards. The potato crop production functions were estimated according to the productive groups in the double logarithmic form of the farmers of the field research sample in the Nubaria region. The value of the total productive elasticity of the elements included in the logarithmic function in the first and second group was about 0.612, 1.726, respectively, which reflects the decreasing return to capacity. Where the value of the total elasticity of the elements included in the quadratic function was about 0.99, 1.29 in the first and second groups, respectively, Finally, the most important problems that impede contract farming were addressed from the point of view of potato growers, as the data indicate that the problem of some contracting parties’ non-compliance with the terms agreed upon in the contracts came in the first place, and it is one of the most important problems. By about 25.2% of the total number of repetitions of about 238. [ABSTRACT FROM AUTHOR]
