Abstract
The aim of the research was to determine and analyze chemical and biological properties of fodder mallow and maize (Eurostar variety) as well as opportunities of their cultivation in pure sowing and when dedicated to fodder. The research was carried out in the years 2011-2012. Plant research material came from field cultivations of fodder mallow (Malva ver-ticillata L.) and maize (Zea mays L.) located on Experimental Station of the Department of Grassland and Natural Land-scape Sciences at Poznań University of Life Sciences located in Brody Experimental Farm (52° 43’ N, 16 ° 30’ E). The re-search material consisted of fodder mallow plants and maize cultivars Eurostar variety FAO 240. Experimental blocks in three applications formed three variants of nitrogen fertilization: 120 (control), 160 and 200 kg of N·ha-1. Larger doses of nitrogen enhanced a content of crude proteins both in the case of fodder mallow and maize. In the case of soluble sugars, larger amounts of applied nitrogen resulted in an increase of this component in maize and a decrease – in fodder mallow. An advantage of fodder mallow over maize consists in a higher richness in mineral components (especially calcium, phos-phorus and potassium). Fodder mallow and maize accumulated similar amounts of silicon, which is favorable for the nutritional value of the obtained fodder. Fodder mallow surpasses maize when the content of crude proteins is concerned. How-ever, a smaller amount of sodium and a higher amount of nitrate nitrogen in fodder mallow may not be positive.
