The field experiments with sugar beet were conducted in 2013–2015.The subject of study were evaluation of the impact of different crops on weeds in sugar beet crop in next growing seasons. The following agricultural crops: spring wheat and oats were sown in an amount and recommended period for their cultivationin spring in 2013 and 2014 year.On experimental plots were not used any chemical protection against weeds. Growing weeds in the field were controlled by a mechanical method - harrowing. In the next season on a singled part of the field the sugar beet varieties Danuśka and Telimena were sown. 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).

The aim of the studies was to determine the influence of mixture Tytanit biostimulant and herbicides (Chwastox Turbo 340 SL, Lintur 70 WG, Mustang 306 SE) on the effectiveness of weed control, yield and quality of spring wheat grain. The tested mixtures had no influence on weed control Chenopodium album, Galium aparine, Veronica arestis and Matricaria indora. However, the addition of biostimulant to a spray liquid containing Mustang 306 SE decreased effectivness in case Viola arvensis. The application of biostimulant with the herbicides Lintur 70 WG and Mustang 306 did not have a significant influence on yield of spring wheat. In 2014 after application mixture of Chwastox Turbo 340 SL and biostimulant significant increase the weight of grain was noted. In these studies, tendency to reduce the quality of the grain (mixture biostimulant with Lintur 70 WG or Mustang 306 SE) and varied impact in both years of investigation (Chwastox Turbo 340 SL) were observed.
