dc.description.abstract	The connection of moisture content in the soil to the total productivity of plants has been established. Indicators of photosynthetic activity of soy crops were higher in years, with better moisture resistance. Fluctuations in the net productivity of photosynthesis over the years ranged from 5.3 (the driest year) to 7.0 g/m2 day (a moisturizing year). The average indicator of the net productivity of photosynthesis during the years of favorable moisturizing was 6.5 g/m2·day, in arid years it decreased by 10.8%. The photosynthetic potential of soybean crops on average for 5 drought years was at the level of 2.5 million m2 / day during the period of branching - flowering, then it was reduced by 16%, which was a direct effect of lack of moisture in the soil. During the years of favorable soil moisture, the photosynthetic potential was quite high and remained for a longer period within 2.7 million m2 / day. The total height of plants in dry years was lower and amounted to 74.5% of sufficiently wet years. On average, 18.1 beans were formed on one plant in arid conditions, this indicator was - 29.0 beans with favorable moisture, which was higher by 60.2% compared to previous indicators. Losses from the fall of generative organs during the growing season were significant in dry years - 81.9, favorable for moisture - 78.0%. In conditions of sufficient moisture, the number of beans with three seeds was increased.
