PECULIARITIES OF USING OF PLANT RESIDUES FOR OBTAINING COMPOSTS
06.00.00 Agricultural sciences
Description
Using of organomineral composts to preserve fertility and restore ecological functions of chernozem soils in the Krasnodar territory is necessary. Their composition depends on the properties of chernozem soils and can include various wastes of industry and agriculture. The main component of compost can be organic wastes of livestock, and plant residues and mineral additives are additional compost components. Peculiarities of the interaction of the components of the organomineralic mixture, which including manure of cattle and phosphogypsum, are considered in the work. In the interaction of organic particles of cattle manure and phosphogypsum particles, structural formations are formed where the phosphogypsum particles are enveloped by particles of cattle manure. The experience of composting this organomineral mixture with various crop residues of crops was carried out. Plant residues according to the intensity of decomposition in composts can be represented in the next row, beginning with more decomposed ones: sugar beet> winter wheat> winter barley> corn> sunflower. The composts obtained were characterized by a well-aggregated structure with a predominance of particles 1-2 mm in diameter, good aeration, low density (1.01-1.10 g / cm3), and favorable humidity (22-25%). The structural factor of composts with different plant residues ranged from 3.1 to 4.3 units. The best physical properties were compost, including plant residues of sugar beet, the worst - sunflower. The combination of an organomineral mixture with various plant residues contributed to a decrease in alkalinity of the substrate, a slowing of the mineralization of organic matter, restraint of ammonification processes, and an increase in the content of total nitrogen and phosphorus

Description
A variety determines the direction of use of grape products and plays a leading role in improving its quality. Preservation of genetic resources of grapes and their studying are very important for modern science. The studied material makes it possible to use the selected genetic characteristics for breeding new varieties of grapes, taking into account the requirements, and introducing them into production, as well as highlighting the most valuable varieties for transferring them to the state variety testing. Among a wide variety of grape varieties, in the ampelographic collection there are varieties of AZOSVIV selection of the technical direction: Krasnostop AZOS and Dostoiniy, for which complete phenotyping was carried out. The phenological and agrobiological information on the grape varieties studied for 2015- 2017 is collected. The presented grades of grapes of the technical direction are characterized by high quality of production. The wines from the varieties Krasnostop AZOS and Dostoiniy are competitive, characterized with high consumer properties; they enjoy the well-deserved fame and were nominees of exhibitions and holders of diplomas repeatedly. Based on the results of microsatellite profiling, the varieties showed a sort-specific general combination of alleles. At the same time, in each locus there is one identical allele, which corresponds to the fact that the varieties Krasnostop AZOS and Dostoiniy have one common parent (Phylloxer-resistant Gemete). The received formulas of a variety (DNA-passports) in practice can be effectively applied to determine the cleanliness of planting stock and plantations of grapes, specification of the parent forms of the sample and in the disputed questions of the authorship of the variety. The study was supported by Federal Agency for Scientific Organizations program for support the bioresource collections

Description
Currently, personal subsidiary farms (PSF) have an important place in solving of the food security problem in some regions and the country as a whole. The organization of optimal and sustainable management strategy of maintenance for PSF should be planned according to the study of functioning of PSF. The authors propose a unified methodical approach for complex accounting of energy costs of external and internal flows involved in the production of agricultural products. Comparative energy characteristic of the functioning of the two personal subsidiary farms located in the Tomsk oblast and having different socio-economic and climatic conditions is presented in the article. Both farms are located in the taiga zone of Western Siberia. Calculations of the energy content of all the incoming and outgoing flows involved in the economic activities of PSF showed that the flow of technogenicanthropogenic energy is the most energy-intensive for both farms. Some conformity in the energy structure of consumption of their own product takes place despite the different types of stockbreeding specialization. An assessment of the level of selfsufficiency in food has shown that more favourable socio-economic conditions create preconditions for an increase of the anthropogenic flow. While PSF located in remote areas are forced to conduct of business activities with maximum using of natural resource potential

The increasing consumption of forest resources causes a greater anthropogenic impact on forest ecosystems and leads to a negative impact on both biodiversity and the environment as a whole. In this article, the sustainability of forest phytocenosises of southeast of Western Siberia is assessed using the example of Tomsk region. The analysis of the status and dynamics of the forests of Tomsk region has been assessed. The main factors negatively affecting the biodiversity of forests of Tomsk region were analyzed. The forests cover extensive areas; therefore, the studies were carried out based on the data from the State Forestry Register of the Russian Federation for the period from 2008 to 2015. According to the results of the study, the sustainability of forest phytocenosises has increased significantly in recent years, which can be explained by its strengthened ability to maintain the current state under the influence of external factors. This work considers such causes of damage and death of forest plantations as pests, forest diseases, unfavorable soil and climate impacts, forest fires, as these are the main and most massive phenomena that cause the greatest damage to forest.

IMPACT OF WAYS OF INCORPORATING RICE STRAW INTO THE SOIL ON RICE YIELD
06.00.00 Agricultural sciences
Description
In the conditions of the two-factor field experiment, the influence of four methods of incorporating straw in the soil on the rice yield was studied: plowing, one-, two- and three-time discs and three ways of "processing" the straw: embedding in the soil of the chopped straw in its pure form, together with compensating nitrogen fertilizer and inoculated stubble biodestructor Stemix ® Niva. It is shown that the lowest yield is formed when straw is plowed, while surface tillage of soil by one-, two- and three-fold discs significantly increases the grain yield in comparison with the plow by 2.4, 4.2 and 5.2 c / ha, respectively. Taking into account that the double disking provided an almost twice increase in the yield of the crop and the absence of statistically significant differences with the triple disking; it is this method of incorporating the straw that should be considered the most expedient. The introduction of a compensating nitrogen fertilizer ensured a reliable increase in yield by 5.1 and 3.7 centners per hectare in comparison with the variants with the introduction of straw in pure form and treatment with biopreparation. Calculation of the share of the influence of the factors studied on the rice yield showed that the method for embedding straw provides 29.9% of the variability of the trait under study, the method of straw treatment is 36.7%, and the residual dispersion accounts for 33.4%. Incorporation of chopped rice straw in the soil together with compensating nitrogen fertilizer in the amount of 1% of the mass of straw, by double discing, ensured the receipt of a conventionally net income of 6940 rubles / ha, the rate of return - 70.4% and the cost recovery - 1.7 rubles / rub
