Abstract
The field experiments were conducted in 2013–2015. White mustard, sunflower and alfalfa were sown on the experimental plots at a rate and term recommended for their cultivationin in spring of 2013–2014. None herbicides were used on the plots and weeds were controlled mechanically by harrowing. In the next growing season (2014–2015) two sugar beet varieties Danuśka and Telimena that differed in leaf shape were sown on these plots. Weed density and fresh weight of weeds were assessed using a framing method estimation. Plants growing in forecrop had an influence on the species and weed number. The significant effect of white mustard on the number and fresh weed weight decrease was found. Reduction of weed infestation had a positive effect on the growth and development of sugar beet crops. Weeds had greater impact on the growth and development of the variety characterized by smaller leaf area (Danuśka) than the standard cultivar (Telimena). Doświadczenia poletkowe prowadzono w latach 2013–2015. Wiosną w latach 2013–2014 na poletkach doświadczalnych wysiano gorczycę białą, słonecznik oraz lucernę siewną w ilości i terminie zalecanym do ich uprawy. W doświadczeniu nie stosowano chemicznej ochrony roślin przed chwastami, a występujące chwasty niszczono mechanicznie poprzez bronowanie. W latach 2014–2015 na poszczególnych poletkach zasiano buraki cukrowe o różnym typie ulistnienia – odmiany Danuśka i Telimena. Na poletkach z burakiem cukrowym określono liczebność oraz świeżą masę poszczególnych gatunków chwastów. Rośliny uprawiane w przedplonie miały wpływ na liczebność i skład gatunkowy chwastów. Jedynie uprawa gorczycy białej przyczyniła się do istotnego obniżenia liczebności oraz świeżej masy chwastów. Redukcja zachwaszczenia pozytywnie wpłynęła na wzrost i rozwój buraka cukrowego. Występujące zachwaszczenie w większym stopniu oddziaływało na wzrost i rozwój odmiany odznaczającej się mniejszym pokrojem liści (Danuśka) niż odmiany standardowej (Telimena).
