Sažetak
The infestation and damage caused by the European corn borer (ECB), as one of the most important pests of corn, are influenced by various factors. Research on the impact of different soil tillage systems and corn fertilization on attack and damage of ECB was conducted in year 2021 in Križevci (NW Croatia). The influence of conventional tillage (ST), deep loosening (CTD shallow loosening (CTS), fertilization as recommended (FR), FR with addition of biophysiological activator Geo2 (FRG) and fertilization reduced by 50% (F50%) and F50% with addition (F50%G)) of biophysiological activator were determined. The results of the research showed that the tillage system, corn fertilization and their interactions have a significant influence on most of the measured parameters of intensity of infestation from the ECB (percentage of stem, ear shank and ear infestation, number and length of holes in stalk, number of caterpillars per plant), but not for all. Variants ST, FRG and FR and their interactions resulted in the highest infestation intensity in most parameters, but the tillage system had no significant effect on the percentage of ear shank infestation, and fertilization did not affect the percentage of stalk infestation and the number of caterpillars per plant. The highest ear mass per plant was found in soil treatment CTS and ST, in fertilization FRG and FR and in the interactions of CTS and FR and ST and FRG.
