Abstract

The hybrids OSSK 373, OSSK 444, OSSK 494, OSSK 552 of different FAO maturity groups (FAO groups 350, 450, 490 and 590 respectively) were grown at eleven locations in five years (1999-2003) in macro trials from Račinovci (near Županja) to Luka (near Varaždin). There was an experimental plot of eight rows 100 metar long. Entire plots were machine harvested and the whole quantity of grain was weighed, calculated in t/ha and grain water content was determined. In combined ANOVA, all three effects: location, year and hybrid, were highly significant (F-tast) for two agronomic traits, grain yield and grain water content. Grain yield was significantly higher in later hybrids and OSSK 552 was highest yielding hybrid with 12.16 t/ha. Going westward, water content increased more rapidly in later hybrids, but the magnitude of water content was not excessive (below 29%). Taking higher yield potential of later hybrids into account, as well as possible switching of type of production (grain and/or forage production), it is feasible to increase production of later hybrids in North-West Croatia.
