Features of the production process of soybean varieties from different regions of zoning in the agro-climatic conditions of the Non-Chernozem Zone of the Russian Federation

The aim of the study was to analyze changes in dynamic parameters development sowing early-ripening soybean varieties from different regions origin – northern ecotype, southern and Far Eastern conditions CRNZ Russian Federation with sufficient moisture supply growing season arid conditions. results study. maximum values dry biomass all groups reached by end bean growth period, which corresponds phases R5–R6 (the beginning seed filling full seeds) averaged 3400–5700 kg/ha for varieties, this value varied 3400 Orca ecotype 5700 Avanta variety moisture. In extremely 2010 were R4 phase made beans, there no further increase, decreased 2 times compared seasons moisture, ranged 3250 varieties. As a result analysis production process temperature humidity regime season, it found that correspond possible variability greater extent than and, along can be recommended cultivation Federation. acutely (GTK < 1), fundamental differences between according peculiarities process, them formed smaller
