Main Factor

Soybean is one of the most important agricultural crops, which although in general very unpretentious, but under the environments of the Altai Territory (Prialeyskaya steppe) it is almost impossible to obtain consistently high yields due to unfavorable climatic conditions. The main factor in obtaining consistently high yields and involving additional areas for soybean crop in this climatic zone is the use of complex agrotechnical techniques, namely regular irrigation. The purpose of the work was to develop an optimal mode of soybean irrigation under the environments of the Prialeyskaya steppe in the Altai Territory. The possibility of effective soybean cultivation on the irrigated lands of the arid Prialeyskaya steppe in the Altai Territory has been theoretically substantiated and experimentally confirmed in the paper. The regularities of the influence of different irrigation regimes on soybean productivity have been established. The specific water consumption per unit of marketable output has been determined depending on the irrigation regime. The relations of grain yield with the change of irrigation regime have been established. The maximum yield of soybean grain has been obtained in the 80% LMC variant (the lowest moisture capacity), which was 3,3 t/ha in 2016. The average yield for 3 years of research was 3,1 t/ha and exceeded the yield on the control variant by 2,1 t/ha. In the 80% LMC variant but with the treatment of soybean seeds before sowing with an inoculant the average yield was 3,5 t/ha, which exceeded the yield in the control variant by 2,5 t/ha. Also in the 80% LMC variant and with inoculant seed treatment the yield of soybean grain exceeded the yield in the non-treated variant by 0,4 t/ha. Thus, it has been established that to obtain the maximum yield of soybean under the environments of the Prialeyskaya steppe should support the level of pre-irrigation soil moisture at 80% LMC.

Relevance of subsoil irrigation usage for growing feed crops on alluvial meadow soils is shown. Distribution of pjezometric pressure, along the water emitter line during the irrigating period, is analyzed. Formation of moisture patterns in the soil regarding the quantities of irrigating water and emitters design are considered. In order to define the characteristics of moisture patterns in the soil, depending on the quantities of irrigating water, the ratios of vertical water spreading Kv and forms Kf are calculated. Expediency of usage low irrigating rates is substantiated. As a result of research, mathematical relations were derived in order to define water outlays in the emitters made of pottery tubes with diameter 50 mm under water pressure at the line 0.1?0.7 m. It is determined that usage of subsoil irrigation allows increase of commercial crop harvest, significantly save water resources, labour and energy comparing to sprinkling.

Purpose: to reveal the effect of different doses of mineral fertilizers (MF) on the growth, development and productivity of soybeans on meadow-chernozem soils of Rostov region. Materials and methods. The studies were carried out on meadow-chernozem soils of Oktyabrsky district Rostov region in 2019–2020. Observations of the effect of different doses of MF on the growth, development of plants, yield records, statistical processing of the results were carried out according to generally accepted methods of conducting field experiments. Results. It was found that, on average for 2 years, the greatest plant growth was observed in the variant with the calculated MF dose for the planned yield of 5.0 t/ha. The height of plants in this variant in the branching phase averaged 24.8 cm for 2 years, in the flowering phase – 54.7 cm, and in the phase of bean filling – 117.6 cm. This is, respectively, 23, 21 and 13 % higher than the control. The largest increases in leaf surface area in this variant were revealed: on average for 2 years, they amounted to 13% in the phases of branching and filling of beans and 18 % in the flowering phase. At the same time, in the variant with the MF dose for the yield of 4.0 t/ha, the increments to the control were respectively equal to 9, 16, 13 %, and in the variant with the MF for the yield of 3.5 t/ha – 6, 12, 8 %, respectively. Similar changes were revealed in the accumulation of dry aboveground biomass. Conclusions. The greatest impact on the height of soybean plants was exerted by the application of MF with a dose calculated for the planned yield of 5.0 t/ha. On average, for 2 years, the height of plants in this variant was 117.6 cm in the phase of filling the beans, which is 13 % higher than in the variant without fertilizers. The same tendency can be traced when determining the leaf surface area and accumulation of dry biomass according to the options in the observation phases. Thus, the best conditions for the yield formation were formed in the variant with the calculated dose for the planned yield of 5.0 t/ha. As a result, on average for 2 years, the soybean yield in this variant is 109 % higher than the control.

Peas are superior to many legumes in their nutritional value and contain 20.1-32.4% protein. The amino acids in peas are unique in that they eliminate various harmful and pathological factors in the human body. Growth, development, yield, and yield quality of 75 pea cultivars were studied in dryland conditions. Based on field experiments, it was studied that the genetic characteristics of pea cultivars grown in light grey soils depend on local conditions. From the studied samples, 14 samples with high results compared to the control variant were selected. The yield of the selected samples was 4.4 centners higher than the control variant.

The purpose of the research is to study the water-physical parameters of the soil, on the basis of which it is possible to analyze the moisture regime and draw conclusions about the applied innovative technologies. The results of the experiments; set according to the developed recommendations by the employees of the Altay Botanical Garden. The article provides data on the water-physical properties of the soil: density, humidity and maximum field moisture capacity. The results of the experiments showed that with the help of the «Akvasorb» hydrogel, it is possible to regulate the water regime of soils and increase the moisture reserves available to plants in conditions of water scarcity. Thus, the addition of the preparation at a rate of 1.5 kg/m3 and 2.0 kg/m3 helps to retain the greatest amount of moisture in the soil from 15 % to 24 % across all horizons. These same norms increase the water reserves in the oil, especially in the spring and improve its density. All this contributes to a better development of plants.

This article discusses the methods and standards for the use of complex high molecular fertilizer StresStop on potatoes in the conditions of the Akmola region. The article deals with the influence of the complex high molecular fertilizer StresStop on the yield, marketable qualities and biochemical composition of potatoes, depending on the norms of its application and the phase of development of potato plants. During the phase-by-phase treatment with StresStop fertilizer, at the doses recommended by the manufacturing institutions, the content of dry matter, starch and vitamin C in potato tubers changes, while the content of toxic elements in potatoes does not change significantly. A significant effect of a complex high molecular fertilizer on potato yield was determined. The greatest increase in the potato yield +9.1 t / ha in comparison with the control variant was provided by spraying the variant treated with 0.01% StresStop solution in the full germination + flowering phase, where the yield was 17.5. The use of a complex high molecular fertilizer contributes to an increase in the yield, commodity and quality indicators of potatoes, while the study showed that the content of toxic elements in potatoes does not change significantly

The recognition and interaction of cells with the extracellular matrix (ECM) effects the normal physiology as well as the pathology of all multicellular organisms. These interactions have been shown to influence the growth, development, and maintenance of normal tissue function. In previous studies, we have shown that neonatal cardiac myocytes specifically interacts with a variety of ECM components including fibronectin, laminin, and collagens I, III and IV. Culturing neonatal myocytes on laminin and collagen IV induces an increased rate of both cell spreading and sarcomerogenesis.
