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.

The assessment of weed infestation was performed by framing method estimation of number and fresh weight of weeds. There was no significant effect of cropping spring wheat and oats to reduce the number and fresh weight of weeds. Reduction of weeds infestation influenced favorably on growth and development of sugar beets crops.Weeds had the larger impact on the growth and development of varieties characterized by less leafage (Danuśka) than the standard cultivar (Telimena).
