The aim of the study was to evaluate the level of weed infestation of maize cultivated in organic farming depending on natural fertilization (20 and 40 t of composted manure per 1 ha) and cultivation method: A - control object (without weed control), B - brush weeder (three times during the vegetation season), C - weeding hoe (three times during the season), D - brush weeder (two times during the...
The studies were conducted in the years 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 reaction of two cultivars of sorghum (GK Aron mid-early and late Sucrosorgo 506) the intercrop with corn, compared to pure sorghum seed was evaluated. Corn was represented by a variety of medium-late, with...
The study focused on toxicity evaluation of selected complexing organic compounds (EDTA, rhamnolipids, quaternary pyridylketoximes and pyridineamidoximes) to monocot plant - maize (Zea mays L.) in aquatic and soil systems. Tests evaluating the seed germination and growth inhibition of shoot and root of maize were carried out at different compound concentrations (ranging from 0 to 1000 mg/kg of dry...
The study focused an assessing the influence of xenobiotics, such as NaCl and diesel oil on germination and early development of maize (Zea mays L.). Through the test the seed germination and growth inhibition of shoot and root of maize were evaluated. The experiments were carried out at different xenobiotics concentration and their mix. It was observed that the presence solely of compounds did not...
Studies on the response of maize to use PRP fertilizer was carried out in 2012-2015 in the Department of Agronomy at the University of Life Sciences in Poznan, in the fields of the Experimental Station Gorzyń in Złotniki. Replacement of the traditional maize fertilization with phosphorus and potassium by PRP technology, both full (PRP SOL with PRP EBV) and the PRP SOL led to a significant increase...
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 growth and yield of maize planted after winter rye cover crop. Strip tillage was executed with the use of a universal active tool for the strip tillage and mechanical inter-row...
