ABSTRACT
The article presents the results of 3-year field studies, whose purpose was to assess the impact of
maize sowing method, type of cultivar and NP fertiliser sowing method on the health of maize plants.
Changing weather conditions during the study years significantly differentiated the percentage of maize
plants damaged by pests and affected by diseases. The positive effect of the row method of NP fertiliser
application in maize cultivation not only reduced plant infestation by Fusarium diseases, but also
reduced Frit fly (Oscinella frit L.) pressure. The “stay-green” hybrid was characterized by a significantly
lower susceptibility to feeding of the European corn borer (Ostrinia nubilalis Hbn.) compared to the
traditional cultivar. Sowing maize of the traditional cultivar using the direct sowing system increased
damage to plants caused by Frit fry larvae (Oscinella frit L.) compared to sowing into soil cultivated
in a traditional way. For the “stay-green” type, the method of soil preparation for sowing did not
significantly affect the pressure of this pest. A simplified method of soil preparation for sowing maize
should give preference to cultivating “stay-green” varieties.
