Abstract

Hydrothermal conditions analyzed the growing season (May-August) in Kaluga oblast in the period from 1991-2015 and their influence on yield of soybean varieties Mageva. Found that 52 % of years there has been excessive moisture, 28 percent is sufficient moisture, 20 percent is insufficient hydration. At the same time in the last decade there has been a trend of increasing the number of years with excess moisture. Duration of the vegetation period of soybean varieties in conditions of insufficient humidifying Mageva decreased by an average of 17 days (15,9 %) compared to conditions of excess moisture. It happened mainly due to reduction of generative development period.
