Kamalinsky 7 is a perennial grass of the spring-winter type from the Poaceae family, belonging to the Agropyron genus. The plant features a loose tufted form, stems 60–120 cm tall, smooth and well-leafed, as well as linear, rough leaves 15–30 cm long. The root system is fibrous, penetrating up to 120–150 cm deep, which ensures drought resistance and allows the plant to establish in various soil conditions.
The variety is distinguished by high winter hardiness and the ability to withstand low temperatures, as well as good adaptation to a wide range of soil pH (6.5–7.5) and even tolerance up to 5.6. It grows well on loamy, loamy sand, and sandy soils, including chernozem, dark chestnut, podzolic, and saline soils. The vegetation period ranges from 94 to 109 days.
Kamalinsky 7 is widely used as a hay and silage crop, and to a lesser extent as pasture feed. Hay yield can reach up to three cuttings per year: from 3–12 c/ha in Buryatia to 90–140 c/ha in Central Yakutia. When combined with alfalfa and clover, hay yield increases to 30–40 c/ha. Seed yield reaches 6–8 c/ha, making the variety suitable for producing feed grains.
Agropyron Kamalinsky 7 is characterized by good digestibility and nutritional value: in 100 kg of hay before flowering, there are approximately 60 feed units and 9.2 kg of digestible protein. The hay is readily consumed by horses, sheep, and cattle.
For sowing, early spring is recommended when the soil warms up, with careful surface preparation and mandatory rolling for even incorporation. The sowing rate is about 8 kg/ha, and the sowing depth is 3–3.5 cm. The variety can persist in the sward for up to 10 years, with the best development observed in the second and third years of use.
