Агробиологические особенности и хозяйственно полезные характеристики фестулолиума сорта Аллегро

Abstract

One of the directions of increasing the efficiency of feed production is the creation and introduction of new varieties of forage grasses with improved economically useful characteristics and a wide range of adaptive properties. Festulolium is a new crop with high fodder qualities, which has a pronounced trend towards expanding the area of crops in the country in recent decades. This is largely due to the creation of a line of new varieties of this crop, the accumulation of positive experience of use in production condi-tions for the procurement of high-quality feed. The Allegro variety was bred as a result of intergenera-tional hybridization of perennial ryegrass and meadow fescue, has a high adaptive potential for cultivation in a wide range of soil and climatic conditions, is characterized by high feed and seed productivity. The variety is winter-hardy, medium-resistant to snow mold and spotting, in comparison with ryegrass, resis-tant to lodging, with a high shoot-forming ability. It is characterized by competitiveness when sowing in grasslands. According to the type of development, it belongs to winter plants and does not form genera-tive shoots in the year of sowing. It is characterized by a high yield of green mass — 25–30 t/ha, with the observance of agricultural cultivation techniques and sufficient moisture supply, it is able to form up to 40–50 t/ha of green mass in total for three mowing. The highest yield of green mass is formed in the second or third years of life. The content of carbohydrates in the dry matter of the green mass in the tube exit phase is 13.4–15%, crude protein — 11–13%, crude fiber — 26%.
