Abstract
The effect of a 26- to 31-year monoculture on the weed infestation of two oat cultivars with and without chemical control was studied. The 6-year study was carried out in a static field on podzolic soil of medium dusty clay at the Balcyny Experimental Station. The control comprised of oats grown in a 6-field crop rotation: potato - oat - fibre flax - winter rye - horse bean (Vicia faba) - winter triticale. The oat cultivation in a 26- to 31-year monoculture resulted in a heavy weed infestation. In comparison to oats grown in crop rotation, the number of weeds per 1 m2 in the uncontrolled oat monoculture was over 3-folds greater, while their biomass was over 4-folds greater. The herbicides applied had a similar effect on weed reduction in both fields (namely in crop rotation and monoculture), while their effect on the reduction in weed biomass was 68% greater in crop rotation than in monoculture (36% greater). We found similar weed infestation for the two oat cultivars grown in monoculture
