Shcatula Yuri Mykolaiovych – Candidate of Agricultural Sciences, Associate of Professor of the department of agriculture, soil science and agrochemistry of Vinnytsia National Agrarian University (21008, Vinnytsia, Sonaychna St. 3., e-mail: shkatula@vsau.vin.ua).

Effect of use of herbicides and growth stimulators on the dynamics of leaf surface formation, photosynthetic potential, dynamics of pure productivity of photosynthesis of agrocenoses of common beans in conditions of the right-bank forest steppe is shown. It was found that the best indexes for the photosynthetic performance of the Galactic variety was obtained in the experimental version where the Pulsar herbicide was used in the rate of expenditure of 0.7 l / ha and the growth stimulator Emistim C, in the rate of expenditure of 10 ml / ha: the area of the leaf surface was at the level 39.2 thousand m² / day / ha, the photosynthetic potential was 0.59 million m² / day / ha, and the net photosynthesis productivity was 5.3 g / m² per day
