Specificity of development of agricultural industrial complex of Kirov region

The article analyzes the results of the activities of the agro-industrial complex of the Kirov region in 2019, identifies the factors restraining the growth of economic efficiency of agricultural production, and suggests directions for the development of the agro-industrial complex of the region.

Productivity of perennial herbs on peat-mineral soils in the conditions of Polesie

The results of studies on the productivity of perennial grasses on peat-mineral soil of Polesye are presented. Sowing alfalfa turned out to be the most productive crop among perennial leguminous herbs. Pasture legumes and grasses were slightly different in productivity. The introduction of an additional bean component in pasture mixtures did not contribute to a significant increase in the productivity of perennial herbs.

Ways to preserve soil fertility in adaptive landscape agriculture systems using perennial grasses

The results of introduction perennial grasses of various years of use into rotations of various specializations on biological soil properties, their productivity and economic efficiency are presented.

Efficiency of cultivation of perennial legume-grass mixtures on gray forest soils of Kaluga region

The results of research conducted by the authors on gray forest soils in Kaluga region. Shows the energy efficiency of cultivation of perennial and annual fodder crops are calculated based on actual energy consumption and release of metabolic energy yield. The data on the effect of perennial grasses on the content of humus and the change in the acidity of the soil. The scheme to study the efficiency of common crops of different varieties of red clover, lucerne and festulolium changeable, it provides a brief description of the studied cultures. Shows data on yield of green mass, harvesting of 1 hectare of dry matter, metabolizable energy and crude protein according to variants of experience. On the basis of obtained results the conclusion about the feasibility of using the studied mixtures to increase the energy and protein value of feeds, ensuring the most efficient use of nonrenewable energy, conservation and improvement of soil fertility, sustainability of agro ecosystems.

Agro-energy efficiency of growing intermediate wheatgrass, elongated wheatgrass and yellow alfalfa on downed forage lands in the dry-steppe zone

The justification of agro-energy efficiency of growing new high-yielding drought-resistant varieties and types of perennial grasses, such as intermediate Wheatgrass, elongated Wheatgrass and yellow alfalfa, which provide a positive effect of interaction of legume-cereal grass mixtures and single-species crops that are resistant to abiotic factors while improving hayfields and pastures of the arid zone, is presented. All studied grass mixtures and single-species crops of yellow alfalfa had a high annual yield of gross (21.7–48.7 GJ/ha) and exchange energy (13.5–32.1 GJ/ha) and provided the production of full-fledged feed.

Formation of productive phytocenoses of a long period of use with the improvement of degenerate grass stands

Based on long-term research in the dry steppe zone, recommendations are given for improving low-productive meadow phytocenoses based on the selection of adaptive perennial legumes and cereals, low-cost methods of surface improvement. It was found that the restored grasslands provide up to 13.0–15.0 t/ha of high-quality green mass, which exceeds the productivity of unimproved grounds by 2.4–2.9 times.

Concept of formation of the digital platform of the regional feed production

The article analyzes the main provisions of the departmental project "Digital Agriculture", the activities of the agro-industrial complex of the Kirov region in 2019, special attention is paid to the development of feed production, as a fundamental, defining sub-sector of agriculture, the directions for the formation of a digital platform for feed production at the regional level are proposed.

Effectiveness of the use of direct sowing and mineral fertilizers on the small-contour developed peatbog

The results of studies on the effectiveness of low-cost agrobiophysics and technology tillage perennial grasses on soils depleted and abandoned peat bogs. The combination of direct sowing seed grasses with mineral fertilizers increased the yields of grasses, an increase in reserves of mobile phosphorus and exchangeable potassium in the root layer of soil, mitigation of soil degradation of the peatbog.

Diseases of perennial bean grasses in Western Siberia

The directions and results of many years of research on the development and prevalence of diseases on perennial leguminous grasses (meadow clover, pannonian clover, sainfoin, sowing alfalfa) in Western Siberia are presented. A whole range of diseases was revealed, the intensity of development, which depends on weather conditions, resistance of varieties, plant age, etc.

Influence of the method of sowing and seeding rate on the yield of alfalfa in the south of Belarus

The results of studies on the influence of agrotechnological techniques on the productivity of alfalfa (Medicago sativa), cultivation on agro-peat soils in the south of Belarus were presented. It was established that the yield of green mass on average over 4 years of life was 393.6–517.9 c / ha when sown under cover and 494.3–629.8 centners ha-1 with coverless sowing. Productivity — 56.5–75.1 and 69.5–89.7 centners ha-1, respectively. A positive correlation between the increase in the yield and productivity of the grass stand with an rise in the seeding rate and doses of fertilizers applied was noted.
