ungal development in fodder substrates including maize has noxious effects: changes in technological properties, reduction of nutritive value, the development of mycosis and allergy agents, and the biosynthesis of refuse factors and zootoxic compounds called mycotoxins. The aim of this study was to evaluate the variation in concentrations of major Fusarium toxins along with the analysis of ergosterol...
This paper presents the effects of soil supplementation with different forms of nitrogen fertilizers on select fertilization efficiency indices in two types of maize hybrids and on changes in contents of mineral nitrogen in soil after maize harvest. Nitrogen content in grain of maize and its uptake with grain yield and utilization were significantly higher for slow-release fertilizers in comparison...
This paper presents the effect of soil supplementation with urea and magnesium on nitrogen uptake and its utilization by two different types of hybrid maize cultivars. Based on the results of 3-year fertilization studies, it was shown that for average volume of grain yield of maize, nitrogen content in grain dry matter and nitrogen uptake with its yield was significantly determined by the doses of...
The aim of our study was to assess protein content in grain and its yield for two types of hybrid maize cultivars at varied soil resources of nitrogen as well as the form of nitrogen fertilizer. Field trials were conducted in the years 2009-11 in the fields of the Teaching and Experimental Station in Swadzim that belong to the Department of Agronomy at the Poznań University of Life Sciences. Protein...
A field experiment was carried out in the Department of Agronomy of Poznań University of Life Sciences on the fields of the Research and Education Unit in Swadzim in 2009-10. Two different genotypes of maize cultivated for grain that exhibited different aging rates were compared: ES Palazzo and ES Paroli "stay-green"-type cultivar. The dynamics of dry matter accumulation were assessed 10...
A field experiment was carried out at the Didactic and Experimental Farm in Swadzim near Poznań in 2004-07. Two maize cultivars were studied, six nitrogen doses and magnesium doses. The effects of the mentioned factors exerted on the utilization of nitrogen from the applied mineral fertilizer and on the nitrogen harvest index were studied. The impact of nitrogen fertilization on the mineral intake...
