Field experiments were conducted at the Teaching and Experimental Station in Swadzim near Poznań in the years 2009-2011. They were carried out in the split-split-plot design with three experimental factors in four field replications. Analyses were conducted to investigate four nitrogen fertilization rates and two magnesium fertilization rates on morphological traits of plants and ears in two types...
The paper presents results of multivariate analyses assessing variation in quantitative traits after the application of nitrogen and magnesium rates in cultivation of two types of maize (Zea mays L.) cultivars, i.e. ES Palazzo and the stay-green ES Paroli. The purpose of this study was to assess the multivariate phenotypic variation of 16 objects which are a combination of four nitrogen doses, two...
A field experiment was carried out in 2006–2008, in the Department of Agronomy, University of Life Sciences in Poznań, on the fields of Didactic and Experimental Farm Swadzim. The object of studies was the effect of magnesium dose (applied to the soil or to the leaves) on the occurrence of diseases in maize grown for grain with the use of the hybrid stay-green type LG 2244. The extent of maize plant...
A field experiment was established at the Experimental and Didactic Station in Swadzim near Poznań over 2004-2007 (52°26’ N; 16°45’ E). The experiment was carried out in a ‘split-plot’ design with 3 research factors in 4 field replications. 2 types of maize hybrids, 6 doses of nitrogen and magnesium doses (including methods of their applications) were examined. The effect of these research factors...
Field experiment was carried out on the Didactic and Experimental Farm in Swadzim (52°26’ N; 16°45’ E) near Poznań, in the years 2004-2007. The three-factorial experiment was established in “split-plot” design with 4 replications. The reaction of two maize hybrid types on the application of 6 nitrogen doses and magnesium fertilization was studied. The influence of the studied factors on the content...
