Economically valuable indicators of Lyuboyar barley

Abstract

Relevance. In recent years, the increase in gross grain harvests of grain crops has occurred mainly due to increased adaptability and yield, in which a significant role was played by the introduction of new highyielding varieties into production.Methods. The object of the study is a new variety of spring barley Lyuboyar, entered in 2023 in the StateRegister of Breeding Achievements of the Russian Federation in the Northwestern, Central and VolgaVyatka regions. Yaromir and Reliable varieties were used as standards, and the most popular varieties Nur and Vladimir were used for comparative analysis. The studies were carried out by field and laboratory methods using appropriate techniques.Results. The yield of the new Luboyar variety, which amounted to 7.63 t/ha, consistently exceeds the yield of standard varieties (by 5.8–6.7%) and popular seeds on the market among Russian producers of Nur and Vladimir varieties (by 15.4–32.0%) for many years (2021–2023). The introduction of a new variety into production will allow you to get the highest conditional net income (29 016 rubles/ha) with a profitability level of 81.0% (23.2–43.9% higher compared to Nur and Vladimir varieties).
