The aim of the study was to evaluate the weed infestation of maize grown in mixed sowing with other plant species (sunflower, common bean, vetch). The field experiment was carried out in the years 2014-2016 at the ecological farm in Chwałowice, belonging to the Advisory Agricultural Center in Radom, using the randomized block method, in 4 replications, on the soil of the good wheat complex, class...
Between 2005 and 2008 in Swadzim, on the fields of the Experimental and Didactic Station Gorzyń, a department of Poznań University of Life Sciences, the two one factor trials have been carried out on two soil complexes: rye and good wheat ones. The purpose of the study was to determine changes of selected chemical properties of soils under the influence of the use of natural fertilizers, straw or...
In the years 2005-2008, the trials were established on two soils, rye and wheat complexes in Swadzim, in the fields of the Experimental and Didactic Station Gorzyń, of the Poznań University of Life Sciences. The purpose of the study was to determine changes in selected physical properties of soils under the influence of natural fertilizers, straw or winter intercrop under maize grown for silage in...
The studies were conducted in 2010-2012, at the Agricultural Experimental Station in Swadzim (52°26′20″N, 16°44′58″E), belonging to the Poznań University of Life Sciences, Poland. The response to sorghum intercropping of two maize varieties: Absolut (medium-early FAO 250) and medium-late Vitras (FAO 270) was evaluated, with reference to pure sowing as a control. Sorghum was represented by the medium-late...
Most of products of petroleum have a toxic effects to plants, animals and also to man. Overworked motor oils and mixtures of different petroleum substances are especially dangerous for environment. The aim of this work was to determine the effect of overworked motor oil, diesel and their mixtures on the growth and advancement of chosen species of plants. The effect of increasing concentration of the...
A field experiment was conducted in 2012 to 2013 to determine the effect of tillage, including deep strip tillage, shallow strip tillage and conventional tillage, and weed control method (untreated control, mechanical, chemical) on weed infestation of maize planted after winter cover crop being intended for silage. Strip tillage was executed with the use of a universal active tool for the strip tillage...
