The experiment was carried out according to additive design to study shoot and root competition between spring triticale and field bean during early stages of plant growth. It was conducted in plastic boxes 76 cm long, 15 cm wide and 15 cm deep, filled with 16 kg of aerial dry alluvial sandy loam soil, containing 15-20 percent of silt. The soil was classified as good rye agricultural suitability complex. Appropriate arrangement of boxes and aboveground aluminium foil partitions allowed separating four competition treatments: no competition, shoot, root and shoot + root competition. The results of the experiment showed that at the beginning of species interaction in triticale-field bean intercrop system, root competition is more intense than shoot competition. Triticale outcompeted field bean when crops interacted with their roots, but when only shoots competed, field bean tended to be the dominant species. The study presented did not show definitely that cereal is better competitor than legume during early stages of plant growth
