In weeds of the highest abundance, Echinochloa crus-gali, Chenopodium album, and Polygonum persicaria the effects of their number and weight on the yield, stand height and density have been studied, too. The yield of alfalfa without weeds has been analyzed. Echinochlora crus-galli had the highest competition ability.
