Nowadays, when sustainable agriculture has become meaningful, legume crops, which provide high protein content feed and improve soil properties are of special value. A well-balanced cereal-legume mixtures brings many profits, such as better productivity or ecological benefits as improvement of cereal healthiness. In the aspect of the crop structure in Poland dominated by cereals this issue seems to be of a great importance. The aim of the experiment was to determine the health condition of spring triticale in cereallegume mixtures with diversified share of both components. Spring triticale cultivar Milkaro was sown with two cultivars of yellow lupine – Dukat and Mister. Pure sowing of triticale was compared with 50, 73, 86 and 94 share of triticale in mixture. A positive influence of legume participation in mixtures on spring triticale healthiness was shown. No significant influence on the tested properties of yellow lupine cultivars was stated.
