To study the effect of sowing dates on the grain yield and grain quality of three different winter wheat cultivars, an experiment was conducted at ARDS Turda during 2017-2018. By delaying the sowing date, the winter wheat grain yield decreases, while the grain protein content increases. The biggest loss of grain yield by delaying sowing date was noted to Andrada on sowing date III (6 of Dec. 2017), production decreasing with 1316 kg/ha-1 in comparison with optimal for this variety. Arieşan had the highest grain protein content (16.42 %) and Codru had the highest grain yield in all three experimental sowing dates
