Abstract The article presents the results of experimental studies that solve the scientific problem of studying the influence of sowing dates and seed size on the intensity of flowering and the formation of beans on plants. The research was conducted during 2017–2018, at the experimental field of the "Podillia" Scientific Research Center of the State Technical University of Ukraine, using the agricultural technology generally adopted for the Right Bank Forest-Steppe zone of Ukraine. The research used seeds of common bean varieties: Mavka, Bukovyna and Nadiya As a result of the conducted research, it was established that the maximum number of flowers per plant was recorded at sowing on May 20-22–29.7 pcs., and on May 9-11 – 27.9 pcs. in 2017. The year 2018 is characterized by the largest number of formed flowers on the plant. Thus, the sowing period 5–7.05 – 36.1 pieces, and 15–17.05 – 34.9 pieces stand out with the highest indicators. Then, as from sowing 20-22.05 only 20.8 pcs. The most ripened beans on the plant from the sowing period 15–17.05 – 8.9 pcs., and 9–11.05 – 8.5 pcs. The timing of sowing common beans affects the growth of beans during the growing season. With the largest length of beans, it was determined from the sowing period 4-6.05 – 10.5 cm. And from the summer period 1-3.06 – 10.6 cm, which indicates the improvement of the conditions for the growth and development of plants. The formation of the quality of flowers on a common bean plant is influenced by the size and alignment of the seeds. From large seeds (> 5.5 mm) on average over the years of research is 20.5 pcs., while from shallow only 18.9 pcs. With the highest rate of ripening of beans on the plant, large seeds (> 5.5 mm) with an average of 6.7 pieces are released over the years.
