Promising forage lupine variety Uzkolistny 53

Abstract

   The results of evaluation of a new variety of Uzkolistny 53 in competitive and ecological trials, which combines high yield, technology and resistance to adverse environmental factors, are presented. The research was conducted in the southwestern zone of the Central region of the Russian Federation (Bryansk region). The soil of the fields is sod-podzolic loamy with an average level of fertility, pH 5.3–5.6. Bryansk region is included in the zone of moderate humidification, the hydrothermal coefficient ranges 1.3–1.4. A new forage variety of a narrow-leafed lupine Uzkolistny 53 (Lupinus angustifolius L.) is presented. The variety Uzkolistny 53 forage universal type of use is designed for growing grain and green mass and feeding all kinds of animals and poultry. It is distinguished by its monopodial morphotype, lodging resistance and early maturity. The duration of the vegetation period is 85–95 days, matures simultaneously with early spring grain crops. Grain productivity at the end of the three-year competitive variety trial was 3.04 t/ha, green-mowed productivity – 34.0 t/ha, which is higher than the control by 0.55 and 1.7 t/ha, respectively. The data of quantitative alkaloid content in the seeds for 8 years (2016-2023) are presented. The new variety is characterized by consistently low content of alkaloids in grain (0.042 %) and in green mass (0.01 %). The content of crude protein in the grain is 32.6 %, in the dry matter of green mass – 15.9 %. Cultivation of a new variety of lupine in production will contribute to solving the problem of protein deficiency in forages for all kinds of animals and poultry.
