Abstract:

Cereal-legume combinations have been shown to provide a wide range of benefits, mainly environmental and economic. Good yielding and quality of the mixtures and the high forecrop quality of the area encourage to their cultivation for nutritive fodder, but also as a forecrop for cereals. The benefits of sowings are associated with a significant reduction in weed infestation, especially in organic farms. The purpose of the research was to compare the productivity and quality of mixtures of blue lupine with spring cereals depending on the share of seeds of components at sowing. Field experiment was carried out in the years of 2010-2012 in the split-plot system, with 4 replicates, on the soil of good wheat complex. Mixtures of blue lupine (Lupinus angustifolius L.) with wheat (Triticum aestivum L.), triticale (×Triticosecale Wittm. ex A.Camus) and barley (Hordeum vulgare L.) with a different share of components at sowing (share of lupine 40, 60 and 80%) were compared. The level of yielding of mixtures, structure of the components and the chemical composition of the feed were evaluated. It was shown that significantly larger yields of grains of mixtures were found with the cultivation of lupine mixed with wheat and triticale, than with barley. The best yields were recorded for mixtures with 40% share of legumes, whereas increasing this share resulted in reducing yields, regardless of cereal species. Together with an increase in the share of lupine, there were changes in the structure of the plants in the sowing mixture. The number of pods, seeds and seed weight per plant of lupine increased significantly, while thousand seeds weight decreased, while with cereals, there was only a significant increase in number and weight of grains. A mixture of lupine with wheat had a highest content of protein and fat, while least values of these components were found with the mixture with barley. An increase in the share of lupine seeds at sowing favorably influenced the content of protein and fat, but also resulted in increased quantities of fibre, ash and potassium, regardless of cereal species.
