WPŁYW WSPÓŁRZĘDOWEJ UPRAWY KONICZYNY BIAŁEJ I LUCERNY SIEWNEJ NA ZACHWASZCZENIE UPRAWY WIERZBY WICIOWEJ (SALIX SP.)

The field experiment on willow cultivars was conducted in 2013 and 2014. The aim of the study was to determine the effects of weed infestation on yield of two willow varieties (Turbo and Start) and intercropping white clover and alfalfa on weed infestation. The loss of willow fresh weight caused by weeds varied from year to year and depended on variety of willow. Intercropping of bean plants significantly limited number and fresh weight of annual weeds in both years in comparison to control. Among the analyzed variants white clover addition caused the highest reduction of weeds.
