On the substantiation of the efficiency indicator of sowing machines and complexes

For the country's agriculture, various technical means for cultivating crops using innovative resource-saving technologies are developed and produced. Evaluation of the efficiency of working processes of technical means can be carried out on the basis of a complex of numerical characteristics. As a specific indicator in assessing the technical and economic efficiency of agricultural machinery, energy intensity, metal intensity and others are used. Generalized technical information contained in catalogs, prospectuses, reference materials and the results of statistical analysis of sowing machines and aggregates allows us to divide machines and complexes by kE value into two size groups. Based on this, a scale for assessing the prospects of sowing machines and complexes has been developed, which allows us to justify the choice of sowing machines and units depending on soil and climatic conditions, taking into account agroecological restrictions. The purpose of the study is to develop a mechanism for selecting the most effective sowing machines and complexes.
