Abstract: Purpose. To develop a model of early-ripening soybean variety and to determine the effect of growing conditions on the formation of basic indicators of the yield structure.Methods. Field, laboratory, mathematical and statistical.Results. It was studied that the main features of the soybean yield structure are determined by the biological characteristics of a particular variety. Thus, the variability of the sign is a measure of the reaction of the genotype to the conditions of the environment. It has been established that in the early-maturing soybean varieties, the total number of branches correlates with the number of nodes on the main stem (r = 0.35). The height of plants affects the number of nodes per plant (r = 0.76), and also the height of attachment of the lower bean per plant depends on the total height of plants (r = 0.35). The number of nodes per plant is a prerequisite for the formation of beans on a plant (r = 0.43), and also affects the height index of the lower bean attachment (r = 0.42). The effect of the height of attachment of the beans on the number of beans per plant (r = 0.99) was also investigated. The number of beans per plant, in turn, affects the number of seeds per the plant and these signs have a very strong correlation (r = 0.96). The number of seeds from the plant is positively and closely correlated with the weight of the seeds from the plant (r = 0.79).Conclusions. According to the results of the research, the influence of weather conditions on the growth and development of early-maturing soybean varieties was determined. Thus, the total number of branches is negative and moderately correlated with the temperature of the air, but the height of the plants is influenced by the amount of precipitation and air humidity, both of which have a moderate lack of correlation. It was found that the number of nodes on soybean plants positively correlates with the amount of precipitation and the correlation between these parameters is at the level of weak dependence. There is a positive correlation between the amount of precipitation (weak) and the air humidity (weak) and the negative between the air temperature (moderate) and the height of attachment of the bean. It was established that the air temperature is negative and moderately correlated with the number of beans on plants. It was determined that the amount of seed from the plant is negatively correlated with the air temperature and the amount of precipitation (moderate bond), but the air humidity is positively correlated for the weak level of communication. Formation of the 1000-seed weight is positively but slightly influenced by air temperature and rainfall. Weight of seeds per plant of early-ripening soybean varieties is influenced by such climatic factors as air temperature, humidity and rainfall. As with the amount of seed from a plant, these weather factors are negatively correlated and only the air humidity has a direct relation type.
