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.
