Opis:: A field experiment was conducted in the years 2002- 2004 at the Zawady Agricultural Experimental Station (52o06’ N; 22o06’ E), belonging to the University of Podlasie in Siedlce, Poland. The investigated factors were two soil tillage systems (traditional and reduced) and seven methods of weed control in potato canopies with herbicide application. The aim of the study was to determine the influence of tillage systems and weed control methods on the weed species composition and weed density. Tillage systems, weed control methods and atmospheric conditions prevailing in the study years significantly varied weed infestation of potato canopies at the beginning of vegetation and before tuber harvest. The lowest number of weeds, compared to the control treatment, was recorded in the treatments in which chemical and mechanical weed control had been applied. The treatments with the traditional tillage system also showed lower weed infestation than those in which simplifications had been applied.
Doświadczenie polowe przeprowadzono w latach 2002-2004 w Rolniczej Stacji Doświadczalnej Zawady (52o06’ N; 22o06’ E), należącej do Akademii Podlaskiej w Siedlcach. Badanymi czynnikami były dwa sposoby uprawy roli (tradycyjna i uproszczona) i siedem sposobów odchwaszczania łanów ziemniaka z użyciem herbicydów. Celem badań było określenie wpływu sposobów uprawy roli i pielęgnacji na skład gatunkowy i liczebność chwastów. Zachwaszczenie łanów ziemniaka na początku wegetacji, jak również przed zbiorem bulw istotnie różnicowały sposoby uprawy, sposoby pielęgnacji oraz warunki atmosferyczne występujące w latach badań. Najmniejszą liczbę chwastów w porównaniu z obiektem kontrolnym zanotowano na obiektach odchwaszczanych mechaniczno-chemicznie. Również mniejsze zachwaszczenie wystąpiło na obiektach z uprawą tradycyjną niż po zastosowaniu uproszczeń.

Opis:: The present experiment was carried out in the period 2006–2008. The aim of this study was to determine the effect of aqueous soil extracts from the soil of a spring wheat monoculture on seed germination energy and capacity, the length of the first leaf and of the longest radicle as well as the number of radicles. Moreover, the content of 0-dihydroxyphenols in the soil was compared in the last year of the study. The soil used to prepare the solutions came from a field experiment established on medium heavy mixed rendzina soil. Spring wheat, cv. Zebra, was grown using plough tillage and two conservation tillage methods in the presence of undersown crops (red clover, Westerwolds ryegrass) and stubble crops (lacy phacelia, white mustard). Germination energy of the seeds watered with the soil extracts from the ploughed plots was significantly higher than this trait in the seeds watered with the extracts from the conservation tillage treatments with spring disking of the catch crops. Germination energy and capacity of spring wheat in the control treatment watered with distilled water were significantly higher compared to the other treatments under evaluation. Spring wheat watered with the aqueous extract prepared from the soil obtained from the plough tillage treatment produced a significantly longer first leaf compared to the treatments in which both conservation tillage methods had been used. The shortest leaf and the lowest number of radicles were produced by the seedlings watered with the soil extract from the treatment with the white clover stubble crop. Radicle length was not significantly differentiated by the soil extracts under consideration. The content of 0-dihydroxyphenols in the rendzina soil determined during the spring period was higher than that determined in the autumn. The content of 0-dihydroxyphenols in the soil was lower in the conservation tillage treatments with autumn incorporation of the catch crops than in the plots in which plough tillage and conservation tillage with spring disking of the catch crops had been used. The type of catch crop used did not have a significant effect on the soil content of these compounds. At the same time, it was found that the treatments in which the catch crops had been sown tended to have higher contents of these compounds compared to the plots without catch crops.
