The article presents the response of an open pollinated cultivar Warko and a hybrid cultivar Esprit of winter rye grown on good rye soil suitability complex to delayed sowing date, NPK fertilisation levels, fertilisation with microelements and weed control. The experiment was established in a half replication kn-1 type design. The hybrid cultivar Esprit produced yields that were on average 18% higher than those obtained from the open pollinated cultivar Warko. Delaying the date of sowing by two weeks decreased the winter rye yields by about 10%. The response of both cultivars of rye to the sowing date was identical. The effectiveness of yield increase under the influence of the maximum fertilisation rate was higher for the open pollination cultivar Warko. Chemical weed control of rye saved 0.24 t grain per ha. The yield of winter rye was determined by the number of ears per 1 m2 and 1000 seed weight.
