ABSTRACT

The field experiment was carried out in the years 2009–2011 in the Research
and Education Unit in Swadzim near Poznań. Influence of nitrogen dose, type
of nitrogen fertilizer and method of fertilizer application on plant health of
two types of maize cultivars cultivated for grain was assessed in the study.
Incidence of fusarium diseases (Fusarium spp.), corn smut (Ustilago
maydis
), and European corn borer (Ostrinia nubilalis) was noted. A
significant influence of thermal and humidity conditions during vegetation seasons
on harmfulness of the examined diseases and pest was demonstrated. “Stay-green” type
hybrid exhibited significantly lower susceptibility to damage caused by European
corn borer and infestation with diseases than the traditional cultivar. Hence
cultivation of such cultivars should be considered an element of integrated maize
protection, adopted in European Union countries since 1 January 2014. Row application
of nitrogen at the dose from 50 to 150 kg N·ha-1 caused a significant
increase in the percentage of plants infected by fungi of Fusarium spp.
genus. In turn, row nitrogen application combined with top-dressing reduced the
size of maize infestation with this pathogen.

Key words: maize, nitrogen, method of fertilization, Ostrinia nubilalis, Ustilago maydis, Fusarium spp..
