The article presents an agroecological assessment of the cultivation of low-alkaloid varieties of narrow-leaved lupine for green fodder in the conditions of the Kirov region. It was found that the most productive varieties in terms of green mass were Belorozovy 144 (75.0 t/ha) and Bryanskiy kormovoy (71.4 t/ha). The average dry matter content of the varieties of narrow-leaved lupine was 16.7%, which is lower than the controls by 10.8 and 6.8%, respectively. According to the results of the analysis of the crude protein content in the green mass of legumes, it was found that this indicator is 19-34% higher in lupine varieties than in peas. In comparison with peas, the Belorozovy 144 variety (3,9) has a higher coefficient of energy efficiency. In the Bryanskiy kormovoy variety, this indicator is at the level of peas (3.8). These two varieties can be recommended to increase the share of annual legumes in crop rotation.
