The purpose of this study is to identify optimal seeding rates in the conditions of the Moscow region for a group of new varieties (for this region) of vegetable beans. The task was to study the system of the main elements of productivity, which make up the yield. The research was carried out at the ARRIVG – a branch of FSBSI FSVG. The pilot site is located in the Ramenskoye district of the Moscow region in the floodplain of the Moscow River. The soil of the experimental site is alluvial, meadow, medium loamy, moisture-intensive. The lowest moisture capacity of the arable soil layer is 29.5–30.3%, the soil layer is 40–60 cm – 30.0–31.3%. The volume mass of the upper layer is 1.18–1.22 t/m3, the underlying layers are 1.22–1.24 t/m3. Four varieties of vegetable beans (Zhuravushka, Masljanyj korol», Tatiana, Jeksalto) were used as objects of research. The experiment is organized with four repetitions. The plot area is 2.5 m2. As a control, an option with a seeding rate of 350 thousand pcs/ha was selected. Phenological observations, taking into account productivity and the elements of its components, were evaluated in accordance with generally accepted methods. The four studied bean varieties reacted differently to the change in the seeding rate from 350 to 500 thousand pcs/ha. Therefore, when introducing new varieties of vegetable beans for the region, it is advisable to conduct preliminary experiments to optimize the seeding rate. In the conditions of the Moscow region, the maximum seed yield (3.04–3.21 t/ha) was provided by the varieties Jeksalto with a seeding rate of 450 thousand seeds/ha and Zhuravushka with a seeding rate of 400 thousand seeds/ha. The NPP varied from 3.51 to 4.90 g/m2×day, reaching a maximum in the Masljanyj korol» variety with a seeding rate of 350 thousand pcs/ha. Knowledge of the correlation coefficients between the components of seed productivity and the resulting feature – yield is of practical interest not only in breeding, but also in the development of effective technologies, including optimization of the seeding rate.
