The article presents the results of research on biometric indicators of plants, biological productivity and chemical composition of green beans of vegetable beans of the Dialog variety in the conditions of the northern forest-steppe of the Tyumen region, depending on the seeding rate. At seeding rates of 200-400 thousand pieces of germinating seeds per 1 hectare 60 days after the emergence of seedlings, the plant weight was 241.3-361.8 g, the number, area and weight of leaves – 23.1-28.9 pcs., 3231.1-4644.8 cm2, 118.2-183.4 g, the number and weight of beans – 15.9-19.8 pcs. and 70.4-96.8 d, respectively. On average, the yield of green beans of vegetable beans was obtained at the level of 17.8-22.1 t/ha. The analysis of the chemical composition of green beans showed that the protein content, depending on the seeding rate, varied from 6.90 to 7.39%, sugar – 5.21-5.59%.
