The article considers the study results of development of agro technologies for oats variety ‘Konkur’. The characteristics of oats variety ‘Konkur’ which is recommended for cultivation in seven regions of Russia has been given. The paper substantiates appropriateness of research, based on the analysis of data in literature. The meteorological data obtained during the years of research are given. The paper shows influence of studied elements of cultivation technology of the variety on complete germination, plant safety, weediness, moisture reserves in soil during vegetation period and dynamics of content of flexible forms NPK in 0-30 cm. It has been established the complete germination is significantly influenced by predecessor. The plant safety largely depended on seeding rate. Moisture conditions were favourable enough for growth and harvest formation of studied oats varieties. Weeds didn’t influence a lot on obtained results. There was the largest content of nitrate nitrogen on fertilized areas at the beginning of vegetation. The paper gives study results about the effect of predecessors, ways of tillage, mineral fertilizing and seeding rates on productivity and economic efficiency of oats variety ‘Konkur’. It’s been shown that predecessor and fertilizers influenced a lot on productivity of the variety. The primary tillage effected productivity as well. The difference of productivity depending on seeding rate was as a rule within experimental error. The studied variety showed the best economic characteristics after peas with fine tillage. The variety had the best economic effect after spring wheat on plowed fertilized soil.
