An assortment consisting of 10 wheat, 8 triticale and 7 barley varieties were cultivated for three years (2010, 2016 and 2017) in two systems of culture: ecological and conventional on the Simnic luvosoil. The quality of yield seen from the perspective of the protein content, test weight and the weight of 1000 grains were studied from the interactions: species x culture system and variety x culture system. The aim is to promote the species and varieties that are distinguished from the point of view of the quality of the production obtained under the conditions of cultivation in an ecological system, a system that ensures the quality of life by the fact that the yield does not use pesticides and chemical fertilizers. All the varieties experienced in all three species recorded diminished yields, statistically assured under ecological conditions in relation to those sown under conventional crop conditions. In terms of quality, only triticale varieties Titan and Oda obtained at all three quality indices (protein content, test weight and the weight of 1000 grains) simultaneously, values is in the ecological system at the level obtained in the conventional system. From the point of view of the quality of the obtained yield, it was shown that the wheat and triticale did not differentiate between ecological and conventional while the barley showed significant decreases in protein content and weight of 1000 grains under the same reported conditions.
