Cultivation of Gal?ga Orient?lis in the Upper Volga of non-chernozem zone

Field studies were carried out at the Gubino reclamation facility located at the experimental base of VNIIMZ - a branch of the Federal Research Centre V.V. Dokuchaev Soil Science Institute in 2015-2019. We studied promising high-yielding varieties of legumes - gal?ga orient?lis, cereal rhizome grasses - awnless brome grass, canary grass and highly productive of loose shrub grass of meadow timothy. Studies have established that in the legume-cereal hay stands, the share of the gal?ga orient?lis was 18-83%. The share gal?ga orient?lis variety Gale ranged from 19 to 75%, variety Yubilyar from 18 to 79% and variety Krivich from 25 to 83%. On average, over the years of research, with two-fold mowing, the productivity of the gal?ga orient?lis and its mixtures with cereal grasses was 5.9-8.0 t / ha dry weight. The cereal grass mixture with two-cut use provided a dry matter yield at the level of 5.4-7.2 t / ha. The highest level of protein nutritional value was noted in the herbage of the gal?ga orient?lis variety Krivich 17-18%. The yield of green mass of legume-cereal hay herbage was 41.5-56.0 t / ha. Analysis of the dynamics of the density of the gal?ga orient?lis showed that the most dense was variety Krivich in single-species sowing - up to 166 pcs / m2. It was found that among the varieties of the legume component, the tallest, on average, over a five-year study were noted above-ground shoots of the gal?ga orient?lis variety Krivich - up to 117 cm. The gal?ga orient?lis had a high leafiness, the percentage of its leaves was 54-55%. In general, according to the options, the percentage of leaf apparatus in clean crops was 52-56%, in mixed crops - 48-57%. The output of fodder units was 4.7-6.8 thousand / ha.
