The article presents the results of the studies conducted on the typical black soil during 2017 – 2019 under the conditions of TOV «Zolota Niva» of Lubenskiy district of Poltava region. The influence of the precursor, the background of mineral nutrition and pre-sowing seed treatment of sowing time on the yield and quality of winter wheat seeds was investigated. It is defined as indicators of grain quality of winter wheat varieties during the years of research. It is established that the use of different sowing periods in different ways influence the formation of productive potential of wheat plants during the years of research. In order to obtain a high level of yield of the winter wheat varieties we have studied, it is important to first form the optimal number of productive stems per 1 m², the maximum grain weight of 1 ear, and the number of them in the ear. During the years of research, due to different levels of meteorological support and different sowing periods, the highest yield (5.36 t / ha) was provided by the Bohemia variety for sowing on september 20 and the Kosovitsa variety for the sowing period on september 30 (5.29 t / ha). Accordingly, the highest quality grain was formed in the following varieties: Bohemia and Kosovitsa - protein content was 13.1 %, and gluten – 29 % and 29.8 %. Natalka – 12.2 % - protein and 28.1 % gluten content. The Podolyanka grain was of slightly lower quality – 12.2 % protein and 27.2 % gluten
