Research and production introduction of the multipurpose use of narrow-leaved lupin varieties in fodder production in the region will increase the agricultural efficiency with developed dairy cattle breeding. The aim of the research was to study the adaptive properties of narrow-leaved lupin varieties in the Udmurt Republic, to analyze the efficiency of its cultivation. The studies were carried out in the southern agroclimatic region of the Udmurt Republic on gray forest soil. The arable soil layer was characterized by a humus content of 2.1-2.6%, mobile phosphorus - 100-101 mg/kg of soil, mobile potassium - 101-170 mg/kg of soil, and pH KCl from moderately acidic to almost neutral (5.0 -5.6). By the content of crude protein (32%) in grain, narrow-leaved lupin is the leader in the region among leguminous crops. During the research period, a relatively high yield of 1.36-4.95 t/ha was formed by Snezhet’ variety. Varieties Snezhet’ and Vector (S2d = 0.05…0.14) were distinguished by their high resistance to changes in agro-ecological conditions. The combination of ecological plasticity indicators (bi = 0.60) and phenotypic stability (S2d = 0.60) of Crystal variety indicates its high adaptive properties.
