Obriy is an early-season annual lupine created by intraspecific hybridization and selected for its resistance to fusarium and viral diseases. It is a small, bushy-stemmed plant, 40–45 cm tall, with a dark green stem and leaves tinted with anthocyanins. The flower is yellow, and the fruits are round, ribbed, weighing 100–150 g in diameter, with a wall thickness of 7–10 mm. The flesh is juicy, aromatic, has high taste qualities, and is preserved for a long time, making the variety universal for both fresh consumption and processing.
The variety is characterized by high productivity: the average yield of grain is 2.1 t/ha, and green mass – 47.5 t/ha. The internal protein content reaches 40.2%, making Obriy a valuable source of protein for feed and food purposes. Alkaloids are present in low quantities (0.025%), and the dry matter of green mass is 16.9%. The plant height of about 70–72 cm ensures good resistance to wind damage.
Obriy is excellent for growing on acidic and sandy soils with increased acidity. The root system penetrates deep (up to 1.5–2 m), promoting soil structure improvement, aeration, and bringing up mineral substances to the upper layers. Due to the ability to fix nitrogen and decompose inaccessible phosphates, lupine increases the fertility of subsequent crops. It is recommended to sow in late summer – early autumn after harvesting early vegetables, but best of all – in spring on moist soil. Combination with oats, winter, and cover crops enhances the efficiency of the cover crop, and moderate agronomy (sowing depth 4 cm, row spacing 20–30 cm) ensures optimal growth and yield.
