ECONOMIC ASPECTS OF SUSTAINABLE AGRICULTURE ON THE EXAMPLE OF HUNGARIAN SAINFOIN CULTIVATION IN THE CONDITIONS OF THE LOWER VOLGA REGION

The article considers the economic aspects of the use of Hungarian sainfoin for farming biologization and practical achievement of decoupling effect in agriculture through expanded reproduction of soil fertility. Cultivation of perennial leguminous grasses, the root system of which fixes atmospheric nitrogen and structures the soil, protecting it from erosion processes, gives agrobiocenoses ecological stability, which is especially important in irrigated agriculture. The use of these crops in fodder production also has high economic indicators, which allows using them for the practical implementation of the concepts of green economy in agricultural production. The results of the research confirm the economic viability of organic production of green mass of Hungarian sainfoin on light chestnut soils of the Volga-Don interfluve in the Volgograd region of Russia. Organic variants of cultivation of sainfoin with the introduction of straw and green manure showed efficiency comparable to mineral fertilizers and profitability sufficient for organic farming. Thus, the yield of green mass in the conventional version N30P90K70 + N100 (for top dressing) was 47.2 t/ha at 6.23 feed units and 1.25 digestible protein per ton. For the option with green manure and phosphorus feeding, these indicators were 45.3 t/ha, 5.98 feed units and 1.20 digestible protein, respectively. The purely organic variant with straw, respectively, demonstrated 44.1 t/ha, 5.82 feed units and 1.16 % protein. The profitability of the production of sainfoin green mass was 133, 108 and 97 %, respectively, which proves the significant potential of organic farming in the production of green fodder that can be used in the production of organic livestock products certified according to international standards.
