CULTIVAR-RELATED AND AGRONOMIC CONDITIONS OF RYE YIELDING ON GOOD RYE SOIL SUITABILITY COMPLEX

ABSTRACT



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. However, the contribution of these two grain yield componen
