Comparative study of symbiotic activity of legumes when using Risotorphin and Epin-extra

Growth stimulants are substances that provide the growth and development of plants. The aim of this study was to assess the effect of growth stimulants Albit, Energen and Epin-Extra on the cultivation of annual seedlings of Mongolian oak (Quercus mongolica Fisch. ex Ledeb.) in a forest nursery of Primorye Territory. These stimulants were used as a pre-sowing seed treatment in various concentrations of solutions. Control – seeds which have not been treated with preparations. At the end of the growing season, the parameters of seedlings were determined: height, diameter of the root neck, length of the root system, number of leaf blades, leaf surface area and dry mass. It was revealed that the growth stimulator Albit had a more positive effect on the height of seedlings, and Epin-Extra was more effective on the diameter of the root neck. The total dry mass was influenced by Energen. The rest of the parameters were within the control group, or their decrease was observed. In the future, it is planned to study the effect of these stimulants on the subsequent growth of oak seedlings.

A comparison experiment was done on the effective of the new organic-mineral fertilizer Epin Plus and the plant growth regulator Epin-Extra. Epin Plus contains: nitrogen, phosphorus, potassium, boron, fulic acids, 24-epibrassinolide. Epin-Extra contains 24-epibrassinolide. In the field experiment, spring wheat was grown for three years. During the growing season, the plants were sprayed with Epin-Extra and Epin Plus. Field experiment treatment includes: control, with the application of fertilizers and spraying of wheat during the growing season with Epin Plus in dose of 50 ml/ha, 70 ml/ha, 100 ml/ha, with spraying of plants with Epin-Extra at dose of 50 ml/ha. It was found that the maximum grain yield was recorded in the treatment with Epin Plus (70 ml/ha), which was 28.6% more than from control, 21.7% more than the treatment with fertilizer application, 12.2 % compared to the Epin-Extra treatment (50 ml/ha), 22% more than the Epin Plus treatment (50 ml/ha) and 20.2% more than the Epin Plus treatment (100 ml/ha). It was recorded in the control treatment grain protein was 12.9%, and in the Epin Plus treatment (70 ml/ha) – 15.8%. The gluten content of wheat grain in the Epin-Extra (50 ml/ha) and Epin Plus (70 ml/ha) treatment was 33.50 - 35.80%, in other treatment 30.5 - 31.95%.

The paper examines the current state of the land fund, farmlands and agricultural lands in the context of federal districts and individual subjects of the Russian Federation to ensure the increase in production of products obtained by traditional agricultural technologies and organic farming. Qualitative indicators of farmlands and agricultural lands, including indicators of unfavorability, are analyzed. Separately, the problems of fertility regulation (maintenance of humus-forming processes) of farmlands are considered in the conditions of their intensive use on the basis of modern methods of soil fertility reproduction - the introduction of balanced complex fertilizers, reclamation, the use of energy-saving agricultural technologies of tillage, rotation of crop rotations, the introduction of special biologically active substances into the soil, the cultivation of siderates, etc.
