Title : PRELIMINARY RESULTS OF THE INFLUENCE OF SOWING DATES ON THE MOST IMPORTANT SUNFLOWER AGRONOMIC TRAITS
Abstract : Timely, well-made sowing is one of the essential prerequisites for successful sunflower production. In order to determine the influence of the sowing date on the most important agronomic sunflower traits, an experiment was conducted according to a random block design at the Osijek location. The experimental material included 22 hybrids of the Agricultural Institute Osijek and three introduced foreign hybrids. Sowing was performed on two dates (21st April and 13th May 2015). The following traits were analyzed: plant height, head diameter, grain yield, oil content, and oil yield. Significantly higher values were found for the plant height and head diameter in the second sowing date and the oil content in the first sowing date. Grain and oil yields were higher but not statistically significant at the second sowing date. The Experimental hybrid OS-H-10 had the highest yield of grain (6.970 t ha-1) and oil (3.448 t ha-1), while the experimental hybrid OS-H-4-2 had the highest oil content (55.61 %).
