“…pratense is smoothed out by its use in mixed crops of perennial legumes and cereals. The formation of highly productive agrophytocenoses involves the selection of species composition considering their morphobiological features and the improvement of nitrogen nutrition of cereal components due to symbiotic nitrogen fixation of legumes, which contributes to an increase in yield, the balance of the feed mass in terms of sugar-protein ratio and energy [4,5]. Allelopathic properties of plants, specifics of their relations with each other and with the environment, stability of the plant community, etc.…”

In the conditions of northern arable farming, the productivity and nutritional value of the dry mass of pure stand of Tr. pratense and three-component agrophytocenoses with the participation of meadow clover, as well as legume and cereal representatives (Galega orientalis Lam., Medicago varia Mart., Bromus inermis Leys., Phlum pratense L.) were studied. Against the background of spring fertilizing with N45P60K90 and two-time mowing, the yield of dry biomass of grass mixtures averaged 8.3-8.8 t/ha over four years compared to single-species sowing of meadow clover (7.8 t/ha). In terms of energy and protein productivity, the maximum indicators of one hectare were provided by agrophytocenoses of clover (7.54 thousand feed units, 84.8 GJ of exchange energy, 1.22 tons of crude protein) and clover-timothy with the addition of galega or alfalfa (up to 7.19 thousand, 87.7 GJ, and 1.09 tons, respectively). The highest nutritional value of the feed mass (up to 16.71% of crude protein and 138 g of digestible protein/feed units) was allocated to a single-species clover herbage.

“…Расширение видового и сортового наборов многолетних злаковых трав, разработка и внедрение технологий их возделывания -эффективный способ повышения устойчивости кормопроизводства, валовых сборов и качества растительного сырья [1][2][3][4]. Среди селекционных подходов решения проблемы улучшения хозяйственно полезных и адаптивных свойств новых сортов многолетних трав одним из перспективных методов является отдаленная гибридизация для изменения таких видов, как овсяница луговая, овсяница тростниковая, райграс пастбищный, райграс многоукосный и др.…”

Festulolium (× Festulolium F. Aschers. et Graebn.) is a new crop, the varieties of which are created by the method of species hybridization in the Lolium and Festuca genus system. A new amphidiploid cultivar Ayvengo was obtained as a result of intergeneric hybridization of multi-cutting ryegrass and reed fescue (Lolium multiflorum Lam. × Festuca arundinacea Schreb. subsp. arundinacea). Registered in the State Register since 2022. Tetraploid variety of ryegrass morphotype. It is characterized by a combination of fodder advantages of multicut ryegrass with winter hardiness, drought resistance and longevity of cane fescue, high ecological plasticity. According to the type of development, it belongs to winter plants and does not form generative shoots in the year of sowing. Differs in resistance to diseases, competitiveness in grass mixtures, fast and intensive regrowth after grazing or mowing. Distinctive morphological features, features of growth and development of this variety, as well as its fodder qualities, productivity, chemical composition of green mass, its advantages and differences from the standard festulolium variety VIK 90 are given. The seed yield of the Ayvengo variety, on average, for two tabs of the competitive variety trial was: in the first year of use 1.09 t/ha, in the second year — 0.66 t/ha and in the third year — 0.34 t/ha. On average, over the three years of use, the seed yield was 0.70 t/ha, which is 10% more than the standard variety VIK 90. In terms of feed quality and fodder productivity, hay yield, the new variety is 10.7–19.9% higher than standard and analogues of varieties of the original parental forms.
