Zusammenfassung:
The purpose of the study is to determine the optimal volume of fodder and grain-fodder crops of appropriate quality to meet the needs of the livestock industry using a systemic comparative economic approach. For the economic assessment of crops for fodder purposes, a systemic comparative economic approach to their production efficiency has been developed. Accounting was carried out according to the three most important indicators in fodder units: quantitative indicators-productivity per hectare of sowing, qualitative-the content of vegetable protein and cost-the production cost. Oats were taken as the primary culture. Their comparison made it possible to determine economically interrelated partial indices, which are reduced to the index of the systemic comparative economic approach, which contributes to optimizing the structure of the cultivated areas of these crops. This technique allows to determine each forage crop's location in each farm or region's conditions, analyzing the real situation and assessing the prospects for the development of production. The optimal structure of sown areas for grain-fodder and fodder crops, focused on the cultivation of high-protein crops, for the enterprises of the Northern forest-steppe zone of the Republic of Bashkortostan is proposed. Due to a change in sown areas' structure, the gross harvest increases by 8%, digestible protein by 2%, and reduced production costs by 48%.
