Guslyar – perennial ryegrass (Lolium perenne L.), a perennial loosely-stemmed basal grass with a rich basal leaf system. It is widely used in the creation of cultivated pastures and hay meadows, and is also used for seed production. Due to its high winter hardiness and ability to grow quickly after mowing, this species is well suited for both mixed swards and homogeneous lawns.
The plant structure is characterized by oval stems 60–105 cm high, without hairiness, colored dark brownish-green. Leaves of linear shape 16–24 cm long also have a dark green color and are not covered with hairiness. Spikelets grow in inflorescences 21–24 cm long, remaining green; seeds are of medium size (5–6 mm) of a grayish-light shade. High leafiness of the plant – about 87% – ensures a dense and stable structure of the sward.
A powerful root system contributes to good soil fixation, increases resistance to erosion and improves water absorption. The optimal mowing height is 5 cm when the total sward height reaches 12–15 cm, which allows maintaining productivity and health of the culture throughout the season. Guslyar combines high dry matter yield (approximately 5.5–6.1 t/ha) with excellent winter hardiness, making it a valuable choice for pasture and lawn systems.
