The aim of this study was to compare the efficiency of sowing clean and mixtures of spring wheat and triticale, on light soil without the use of chemical production means. The field experiment was conducted in 2009-2011, in a randomized block system with four replications. Varieties of wheat: Bombona and Zadra and Dublet triticale grown in pure sowing and in their mutual mixtures: Bombona+Zadra, Bombona+Dublet and Zadra+Dublet. Mixtures were seeded in a proportion of 50/50% relative to pure seed. Grain crops and the number of stems and crop components were determined. The studies have shown that the spring triticale in pure sowing was the most efficient in yielding - significantly higher than spring wheat varieties and mixtures of: Bombona+Zadra and Bombona+Dublet. It was the result of higher values for all components in triticale crops. Mixtures of crops on average, were similar to the median of their constituent components, however, they showed a large variation over the years. In a favorable year 2010 for cereals, they yielded below expectations, but they yielded the best in the low yielding year (2011). The cultivar mixture of wheat did not differ from the wheat and triticale - wheat mixtures. Among the interspeces mixtures, a combination Zadra+Doublet showed the trend towards higher yielding.
