The lupin variety "Kristall" is characterized by rapid initial growth and simultaneous maturation, ensuring high resistance to cracking and seed shattering. Plant height is 45‑55 cm, with lateral branching blocked at the level of 3rd-4th order branches, which limits growth and promotes denser sowing.
The vegetative period for green mass is 50‑60 days, and for seeds – 96‑104 days. Adhering to cultivation technology and favorable weather-climatic conditions allows for a decent yield: average green mass yield 350‑455 kg/ha, for grains – 20‑25 kg/ha. To achieve maximum productivity, sowing is recommended after early cereals with soil temperature from +5 °C and a 5-day gap.
Cultivation technology includes soil preparation: 1–2 harrowing, winter plowing, harrowing and rolling for field leveling. On sandy soils, single or double harrowing with heavy harrows is applied; on more cohesive soils – pre-sowing cultivation at a depth of 7–8 cm. The lupin root system fully supplies the plant with nitrogen, however, phosphorus and potassium should be applied to the main application (60‑80 kg/ha active substance). To improve the uptake of trace elements, chelated micro-fertilizers (LF-Legumes, LF-Biobor, LF-Biomolybdenum) and growth stimulants are used. Pre-sowing seed treatment with ultraviolet light, fungicide and potassium humate increases germination and yield.
Lupin "Kristall" is an excellent predecessor for most crops: after its sowing, up to 115 kg of nitrogen, 120 kg of potassium and 30 kg of phosphorus can be obtained on the field, which significantly improves soil fertility. Due to high resistance to frost (down to –3‑4 °C) and optimal soil preparation, this variety is suitable for a wide range of climatic zones.
