06.00.00 Agricultural sciences
Description
The results of long-term population-genetic studies in wheat pathogen system “wheat – dangerous disease pathogens” associated with the study of the structure, variability, forecast of plant pathogen development and the host plant genetic diversity are introduced. It is shown that it is necessary to develop polymorphic genetic disease resistance of plant populations to rehabilitate the agroecosystem phytosanitary state, which is possible only on the basis of broad genetic diversity of source material, taking into account the intraspecific differentiation of pathogens and tendencies of the changes

EFFICIENCY OF IRRIGATION REGIMES FOR GRAIN SORGHUM ON CHERNOZEMS
06.00.00 Agricultural sciences
Description
The article results the study of irrigation regime im-pact on water consumption and yield of grain sor-ghum. It is established that optimal conditions for growth and development are created by maintaining soil moisture content in a soil layer of 0.6 m higher than 80 % of field capacity (FC), where the grain yield reaches 14 t/ha and the best indices of profit and cost-effectiveness are obtained

SEEDS AS A SOURCE OF SUNFLOWER PHOMOPSIS SPREAD
06.00.00 Agricultural sciences
Description
The ability of Phomopsis to transmit from affected seeds to plants has been studied in both anamorphic and teleomorphic phases of its development in the year of sowing. The sunflower lesion with Phomopsis affects not only the germination, but also causes the plant disease

HUMUS CONTENT CALCULATION THE METHOD WITH USE OF REMOTE SENSING OF THE EARTH
06.00.00 Agricultural sciences
Description
In the article, we have made an attempt to develop and calculate a model of humus content estimation in the black leached soil according to remote sensing of the ground. We have presented the model which has a number of restrictions for its continuous use when carrying out soil environmental monitoring of land grounds. It is established, that for calculation of similar model it is necessary to perform the cameral works including selection and the preliminary analysis of fields, including using of contemporary records of Remote sensing of the ground for definition of sampling points, to carry out an assessment of space photo shooting and sampling of soils in optimum terms with the maximum synchronism (cameral work and soil and agrochemical inspection), to make the analysis of the selected samples of soils for humus content with traditional methods, and finally to calculate regression models with use of data of the carried-out space shooting and the agrochemical analysis of soil samples

EVALUATION OF TURF QUALITY FOR COOL SEASON SPECIES AND CULTIVARS
06.00.00 Agricultural sciences
Description
Series of field and laboratory studies were conducted from 2011 to 2012 in Russian State Agrarian University to evaluate a collection of 4 turf grass species and 15 cultivars for quality, summer density, ground cover and germination percentage. During 2 experimental seasons the plants have been growing with the extensive treatments. Turf quality was evaluated visually using a 1 to 9 scale. The two-way analysis of variance was used to identify genotype’s effects on density, ground cover and germination percentage
