The article presents the results of research for 2017-2019 of soybean varieties of the Northern ecotype of Chuvash Research Agriculture Institute –Branch of the North-East. The research was conducted in the southern part of the Volga-Vyatka region on gray-forest heavy loamy soils. The object of study was four early – maturing (maturing at the sum of active temperatures above 10 0 C-1800-2000 0 C) soybean varieties of the Northern ecotype of the Chuvash selection: Chera 1, Memory of Fadeev, Lumaria and Merchen. The highest yield on average over the years of study was observed in the Memory of Fadeev variety (1.38 t / ha), which exceeds the standard Chera 1 variety by 7 %. According to the research results, the lowest yield variability was found for the Memory Fadeev variety (6.19 %), while the standard variety has 19.85 %. The analysis of the relationship between the yield of soybean varieties of Chuvash selection and the main factors of climatic conditions in the southern part of the Volga-Vyatka region. Correlation analysis showed the degree of influence of various meteorological conditions on the formation of the yield of the studied soybean varieties, which allows a more targeted approach to the choice of cultivating varieties for specific climatic conditions.
