Abstract: Introduction Fescue (Festuca arundinacea Schreb.) is a long-lived grain characterized by high productivity, good feed quality, and a positive effect on soil fertility.When irrigated in the Lower Volga region, it guarantees the expansion of crops of long-term bean-bluegrass grass mixtures, a source of full-fledged feed for farm animals.Attracting this bluegrass crop to the region's feed production contributes to high and stable yields within five to seven years.Object.The object of research is reed oatmeal («Shura» variety), which is cultivated for seeds and green fodder.Materials and methods.Field experiments and accompanying observations were carried out in accordance with generally accepted methods in the experimental field of the all-Russian research Institute of irrigated agriculture.Results and conclusions.The highest seed productivity was observed in the second and third years of herbage life: 600-700 in summer and 400-600 kg/ha in spring.The wide-row method (row spacing width of 0.30 m) provided improved growing conditions and the formation of large seed yields.In comparison with the ordinary (row spacing width of 0.15 m), the seed yield on these variants was 12-15% higher.As a result of research, the main parameters for creating productive seed stands of fescue were determined: summer sowing period (first half of August); wide-row method of seed placement (0.30 m), seeding rate of 3.0 million germinating seeds per hectare.Obtaining high yields of green mass in the second mowing on these crops was recorded on an ordinary method with a seeding rate of 6.0 million / ha -26.0-34.0t / ha.Determining the accumulation of root mass at the end of vegetation indicates a progressive increase from 5.5 in the first year to 16.0-17.0t / ha in the fifth year of life with a content of 140-180 kg of nitrogen, 30-60 phosphorus and 180-215 kg / ha of potassium.Combined use of oatmeal on irrigated land contributes to the production of 300 to 700 kg of conditioned seeds and 20-30 t / ha of green.
