    A field experiment was conducted in the years 2004–2007 at the Experimental Farm in Zawady owned by the University of Podlasie. The experiment was a split-block design. The following factors were examined in the study: triticale proportion in a mixture and cultivation system. Variance analysis associated with the design was performed and means were separated using the Tukey’s test.The studies indicated that different cultivation systems had no significant influence on canopy architecture. Triticale proved to be more competitive than wheat although, when cultivated in mixture with rye, it did not manage to outcompete wheat. The greatest number of ears was harvested from mono-cropped plots and the plots under the mixture with equal shares of triticale and wheat. The longest were the stems of plants harvested in the year 2005 and plants cultivated in two- or three-species mixtures with a 50% share of rye. The presence in mixture of much longer rye plants resulted in increased average ear length. However, the differences were significant only for mono-cropped rye; an interaction of mixture type and cultivation system was significant, too. The greatest grain number in an ear resulted from the largest spikelet number. Significantly greater was the number of grains in ears from plots under rye cultivated in mixture with triticale.

    Studies were carried out in the years 2004–2007 at the University of Podlasie Experimental Station in Zawady. The factors investigated in the study were as follows: cultivation of cereal species (winter wheat, winter triticale and rye) in pure stand and in mixtures (numbers in brackets specify grain proportions of individual species at sowing), and cultivation system. A field experiment was designed as a split plot arrangement of treatments. The results obtained were subjected to analysis of variance and mean separation was obtained by the Tukey’s test. Mono-cropped winter wheat grain was characterized by the lowest protein content. Wheat cultivated in mixtures accumulated more protein in grain, the accumulation being particularly stimulated by competition with rye. Significantly more protein was obtained in the grain of intensivelycultivated wheat. No significant differences in winter triticale grain protein content were found resulting from competition with other species. On the other hand, there was confirmed significance of weather conditions in individual growing seasons, cultivation system and an interaction between the two factors. Significantly most protein was accumulated by triticale cultivated in the third study year. Like for wheat, increased fertilization significantly influenced triticale grain protein content, too. Response of rye was similar to the response of winter triticale. No differences were observed resulting from different proportions in mixtures. Significantly more protein in grain was associated with intensive cultivation. Moreover, significantly more protein was obtained in grain in the third study year, compared with the first year. Significantly most protein was recorded in the plots where wheat was cultivated in pure stand. In all the rye treatments there was observed a tendency towards reduction in protein yield, compared with triticale treatments.
