This paper introduces possibilities and conditions of teaching Russian with the use of the learning modular system Moodle. The experience of using this platform of teachers of National Research Tomsk Polytechnic University (Russia) is analyzed. We consider conditions for the optimization of the learning process which includes the use of traditional and innovative technologies to form student's actual speech competencies with the help of digital educational resources, interactive technologies, and his independent work. The tools used help to ensure training of highly qualified professionals to meet the needs of modern society, and are judged to be a necessary condition for the development of communicative and social competencies among Russian and foreign students studying at Tomsk Polytechnic University

Spring bread wheat is cultivated in the Omsk region, mainly in grain-fallow crop rotations, repeated and perma[1]nent crops, less in crop-changing rotations and occupies up to 73% of the grain share of Western Siberia. Soybean crops are growing in the region, but at the same time, there have not been sufficiently studied the peculiarities of the cultivation technology of spring wheat sown after this forecrop. The purpose of the current study was to establish the efficiency of agricultural cultivation technologies of spring wheat in the crop rotation sown after soybean in the southern forest-steppe of Western Siberia. The study was carried out in a stationary crop rotation with alternating crops (soy[1]beans – spring wheat – oil flax – barley) in the laboratory for resource-saving agricultural technologies of the Omsk Research Center on meadow-blackearth soil in 2011–2019. There has been established that the soil cultivation system and the means of intensification influenced the elements of fertility and the phytosanitary state of the agrophytocenosis of spring wheat sown after soybean. With subsurface plowing, in comparison with moldboard plowing, there was an increase in biomass and number of weeds on 21 and 43%, respectively. The use of chemicals resulted in a significant increase in spring wheat biomass (on 1.8 times) and a decrease in number of weeds (on 3.3 times), which had a noticeable effect on the productivity. Productivity of wheat sown after soybeans decreased with a decrease in tillage intensity from moldboard plowing to subsurface plowing on 16%. The intensive cultivation technology of spring wheat increased its productivity up to 3.32 t / ha, the protein and gluten content in grain on 16–18%. As for chemicals, the maximum grain number increase on 28.2% was provided by the use of fungicides compared to the control (1.46 t/ha).

There is a great number of repeated and permanent spring wheat crops with insufficient areas occupied by forecrops of the first group in the grain-sowing zones of the Omsk region, which leads to a decrease of soil fertility, productivity and grain quality. The aim of the research is to reveal the influence of rapeseed forecrop on fertility, phytosanitary state of agrophytocenosis, productivity and technological properties of spring wheat grain in the forest-steppe of Western Siberia. Complex studies were carried out in a stationary crop rotation of Omsk Agrarian Scientific Center (rapeseed-wheat-soybean-wheat) in 2011-2017. The effectiveness of different intensity impact of soil cultivation systems in crop rotation and effectiveness of intensification means were studied in a two-factor experiment on meadow-black soil. The influence patterns of agricultural technologies on soil fertility elements, phytosanitary state of agrophytocenosis, productivity and technological parameters of grain were established. It was found that in case of intensity decrease of soil cultivation systems in a crop rotation, especially with limited application of intensification means, there is a spring wheat yield decrease after rapeseed forecrop by 0.17 t / ha. Grain yield increases to 2.88 t / ha in case of complex usage of chemicals, with a decrease of variability over years (variation coefficient) from 55 to 37% or by 1.5 times. The application of fungicides reduces the development and prevalence of infections on the upper layer of leaves and increases yield by 0.56 t / ha or by 27.5%. An increase of the mass of 1000 grains, the nature of grain, the content of protein and gluten was observed on the variant of intensive cultivation technology.
