Abstract
In past few years, in the area of northwestern Croatia (Međimurje County, Varaždin County and Koprivnica-Križevci County), the interest of agricultural producers in sunflower cultivation is increasing. In 2020, the Ministry of Agriculture conducted a comparative field on trial with 20 sunflower hybrids at two locations: Koprivnica-Križevci County and Osijek-Baranja County. The aim of the study was to determine the differences in yield and physical and chemical sunflower grain properties. The average yield of sunflower seeds in Osijek was 4,091 t/ha, and in Koprivnica 3,970 t/ha. The average value of hectolitre mass was 43,4 kg/hl in Osijek, and 43,5 kg/hl in Koprivnica. The average weight of 1000 grains was 52,42 g in Osijek, and 54,10 g in Koprivnica. The average oil content of sunflower grain dry mass was 51,88% in Osijek, and 50,75% in Koprivnica. The growing conditions for sunflower differ significantly between the two locations. It is planned to conduct comparative field trial in the next two years to examine the adaptability and stability of the tested hybrids. This year results indicate that agro-environmental conditions in northwestern Croatia are suitable for sunflower production with satisfactory levels of yield and seed quality.
