Sažetak
The grain yield of sunflowers is the most important goal of growing. Today, in the world and in the republic of Croatia, sunflower is the most often grown as an oil crop. The main yield components of sunflower are 1000-kernel weight, grain mass per head and the number of grains per head. Nowadays in Croatia only foreign hybrids of sunflower hybrids are represented on the market. Thus, the aim of this study was to determine the yield components of sunflower hybrids in 2020. In April 2020, 25 foreign hybrids of sunflower were sown at the experimental site of the Faculty of Agrobiotechnical Sciences Osijek. At the time of harvest 10 sunflower plants were collected from each sunflower hybrid, so that yield components were measured on 250 samples. The yield components measured in this study were plant height, 1000- kernel weight, heads diameter, grain mass per head and the number of grains per head. From the total number of analysed plants, about 25% of plants, or 62 plants, have an average stem height between 186.8 and 195.5 cm and 58 plants had a head diameter in the class of 18.4 to 19.8 cm. The number of seeds per head was also measured, so 55 plants had between 1, 292 and 1, 442 seeds per head, while 52 plants had very close, i.e. between 1, 142 and 1, 292 seeds per sunflower head. About 24% of the plants, i.e. 60 plants, had an average weight of seeds per sunflower head between 67.9 and 78.9 g per sunflower head. From the total number of analysed plants, 34 plants had an average mass of 1000 seeds between 54.7 and 60.6 g.
