Senu is a perennial oatgrass (Vysianitsa species) grown primarily in Ukraine. The seeds range from 1 to 5 cm in size, are green, and are packaged in kilograms. For sowing, a density of 1.5–2.5 kg per 100 square meters is recommended, which ensures a yield of up to 50 centners per hectare.
The plant reaches a height of 50 to 120 cm, has leaves 5–11 mm wide, and flowering occurs in June–July. Oatgrass is distinguished by its high resistance to drought, heat, and frost, making it suitable for cultivation in various climatic conditions – from temperate to subtropical.
Senu is widely used as forage grass: it is suitable for cutting production and is also used in lawns (roadside, construction, sports) due to its strong root system, which ensures resistance to trampling. High protein and carbohydrate content makes it a valuable feed for cattle and other agricultural animals. For maximum productivity, it is recommended to sow 25–35 kg/ha, bury the seeds to a depth of 1–2.5 cm, and cultivate after sowing.
Growth problems include fungal infections (e.g., powdery mildew), bacterial root system damage, and pests – caterpillars, mites, mosquitoes. Prevention involves the use of fungicides, insecticides, and regular nitrogen-calcium-phosphorus fertilizers.
