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.

This paper reviews the potential value of SRW plantations as a habitat for invertebrates. It shows the investigation on the number and biodiversity of insects (both predators and herbivores) populating a plantation in IPP–NRI Field Experimental Station Winna Góra, Poland. The study took place in 2009 and 2010. All together 1840 insects were collected. They belonged to7 orders and 27 families. The most abundant groups were Coleoptera and Diptera orders. The biodiversity index was high. It was determined that SRW plantations are an excellent environment for insects.
