In the paper are presented results of three years studies performed in the period 2008–2010 on effects of cultural practices in stands of Panico-Galinsogetum Tx. et Beck. 1942. association in conventional potato production on the experimental plots in the vicinity of Becej (Northern Serbia). Composition of association Panico-Galinsogetum in experimental control variant builds 31 weed species. From Panico-Galinsogetum community, in the variant with one cultivation (with earthing up) without herbicide applying was found 22 weed species, and at the variant with two cultivation without herbicide 17 weed species, respectively. Herbicide treatments of potato crops as well as cultivation led to significant impoverishment of the weed flora, i.e., reduction in number of weed species, their coverage value, as well as the degree of presence in potato crop. Due to reduction of weed infestation, in variants untreated by herbicides, by application of two cultivations, achieved potato yield was for 8% higher in comparison to the variant with one cultivation. In variants treated by herbicides, potato yield was for 32% higher in relation to the yield on untreated experimental variants. The average number of tubers per plant achieved in variants treated by herbicides was for 40% higher in comparison to the number of tubers in untreated variants. In both cases, in comparison to control variant, cultivation resulted in significantly higher number of tubers per plant.

Praca przedstawia rezultaty trzech badań przeprowadzonych w latach 2008–2010 i dotyczących wpływu praktyk uprawowych na stanowiskach Panico-Galinsogetum Tx. et Beck. 1942 w konwencjonalnej produkcji ziemniaka na poletkach doświadczalnych w pobliżu Becej (Północna Serbia). Skład Panico-Galinsogetum w wariancie kontroli doświadczenia obejmował 31 gatunków chwastów. W wariancie z jednym zabiegiem (z przysypywaniem ziemią) bez herbicydu znaleziono 22 gatunki chwastów z Panico-Galinsogetum, a w wariancie z dwoma zabiegami bez herbicydu stwierdzono 17 gatunków. Zastosowanie herbicydów w uprawie ziemniaka doprowadziło do znacznego zubożenia flory chwastów, tzn. do redukcji liczby chwastów, ich wartości rozprzestrzeniania się oraz obecności w uprawie ziemniaka. Dzięki zmniejszeniu zachwaszczenia w wariantach bez herbicydów zastosowanie dwóch zabiegów doprowadziło do plonu ziemniaka o 8% większego w porównaniu z wariantem z jednym zabiegiem. W wariantach z herbicydami plon ziemniaka był o 32% większy w porównaniu z plonem w wariantach bez zabiegów. Średnia liczba bulw na roślinę w wariantach z herbicydami była o 40% większa w porównaniu z liczbą bulw w wariantach bez zabiegów. W obydwu przypadkach zabieg dał istotnie większą liczbę bulw na roślinę w porównaniu z kontrolą.
