CHANGES OF WEIGHT AND IN-KERNEL CONTENT VALUES OF MAIZE HYBRIDS (OCCITAN, COLOMBA, DK-471) AS A RESULT OF DAMAGING BY EUROPEAN CORN BORER (OSTRINIA NUBILALIS HBN)
The research was conducted in the year 2001 on two fields sown with three different maize hybrids and was based on randomly chosen sample plots. The first survey was carried out on the field sown with hybrids COLOMBA and OCCITAN (total area 120 ha), the second survey was performed on 50 ha of hybrid...
