Abstract: The research was made in 2014 by Aleksandras Stulginskis university research station. Create six variants: binary and ternary mixtures, which are comparable to the homogeneous crop of barley. There were 6 variations of test: binary and ternary mixtures which are comparable to the homogeneous barley crop. Grown cultivated plants, summer barley, oats, spring rape and peas. Research was made in 6 replication. First field area was 48 m-2 (16x3), accounted field – 24 m-2 (12x2). Experiment local soil - calcareous and gleyic cambisol luvisols (Endocalcaric Endohypogleyic Luvisol), medium loam on sandy loamy. Weed infestation assessed tillering cereal and milk stage. Tillering stage set amount of germs pcs. in m-2, and milk stage of weeds pcs. in m-2, and weight of weeds g. in m-2. Barley and grain yield mixtures estimated standard moisture content and grain yield (ton per hectare) of 100 percent purity. Tillering stage of cereal crops, weed infestation mixtures did not differ significantly in the majority of weeds found in mixtures how much less homogeneous than the barley crop. Cereal milk stage of plants mixtures set substantially less congeneric than in spring barley crop: annual weeds were 1.8 to 3.2, perennial - 1.8 to 29.7 times, respectively, and their weight from 2.5 to 9, 1 and from 3.2 to 12.9 times less. Mixtures of crops, grain yield, with the exception of barley-pea and barley spring rape received 1.3-1.7 times bigger than in the culture of congeneric barley
