Seeds Quality and Quantity of Soybean [Glycine max (L.) Merr.] Cultivars in Response to Cold Stress

The aim of the study was to identify response cold stress 16 soybean cultivars by evaluating their emergence, yield level, and seed chemical composition. Studies were conducted in 2018–2019. A total sixteen belonging three earliness groups (early, medium-early late) included. Short-term (3-day) (12/6 °C day/night) applied immediately after sowing (A), 3 days (B) 6 (C) seeds, while long (9-day) (D) seeds. In control plot (K), plants grown under optimum conditions (20/15 day/night). showed that stress, reduced plant emergence 5–10%, depending on treatment. Long had a beneficial effect all (average increase 21.5%), with statistically significant differences 12 trend four cultivars. Short also caused treatments B C (by 6.8 11.6%, respectively). Cold did not significantly affect nutrient content yield. Varietal differentiation found respect composition
