Estimation of soybean cultivar Komsomolka reaction on climate changes in Krasnodar region

Research problem was the estimation of soybean cultivar Komsomolka reaction on the climate warming. In work we used data of soybean studying at the Kuban experimental station of Vavilov's Institute of Plant Industry in 1973-2009. The results of researches at using of a method of regression analysis in consecutive differences have shown that duration of the vegetative period of soybean cultivar Komsomolka decreases with reduction of hydrothermal coefficient of period with temperatures above 15°С and reduction of duration of the period between dates of steady transition through 15 and 10°С in the autumn. The seed productivity depends to the greatest degree on the hydrothermal coefficient of the period with temperatures above 15°С. At proceeding warming of a climate it is possible to predict the productivity reduction of soybean cultivar Komsomolka.
