A Device for Laying Film on Potato Ridges

This article presents the results of field trials and an economic efficiency assessment of a developed film-laying machine designed for potato ridges. The main objective of the study was to evaluate the machine’s operational performance, the quality of the technological process, and its economic advantages compared with the existing manual method. The developed machine was aggregated with tractors of classes 0.9–1.4 and tested under actual production conditions on farms in the Namangan region of Uzbekistan. During the field trials, several key indicators were determined to assess the quality and efficiency of the machine’s operation, including soil density, planting depth, ridge-top width, ridge height, and fuel consumption. The experimental results showed that soil density ranged from 1.14 to 1.16 g/cm 3 , planting depth was 6.7–7.7 cm, ridge-top width was 26.8–29.0 cm, and ridge height was 17.3–18.2 cm. Fuel consumption during operation ranged from 3.1 to 3.9 kg/ha. These indicators were used to characterize the machine’s performance and its suitability for use in potato cultivation. In addition to the field trials, technical and economic calculations were conducted to determine the practical benefits of introducing the developed machine into agricultural production. The economic assessment focused on labor requirements and operating costs per hectare, which are important factors affecting the efficiency of potato cultivation. The results demonstrated that, compared with the existing manual method, the proposed machine reduced labor requirements by 86.23% and operating costs per hectare by 23.51%. These findings indicate that the developed film-laying machine can improve the mechanization of potato ridge preparation, reduce the labor burden on agricultural workers, and lower production costs. Overall, the study confirms the machine’s potential to improve operational efficiency and support more economical potato production under the tested field conditions.
