Influence of drought and hailstorm on the yield and yield components of sunflower

In the paper are presented results of the OS sunflower hybrids in two very different years regarding rainfall and air temperature. In 2002 year, amount of rainfall and air temperature were optimal, but in 2003 is recorded unprecedented drought during the vegetation period and heavy hailstorm on the beginning of July that caused a huge damages of hybrids on the experimental field of the Agricultural Institute Osijek. In the research were analyzed: plant height, mass of 1000 grains, grain yield, oil content and oil yield. Based on the analyzed traits, results in 2002 year were significantly better in comparison to 2003 year. The OS sunflower hybrids were shown a high potential for grain yield, oil content and oil yield as well as emphasized drought tolerance. In conditions of significant leaves, stem and head damages by hailstorm, our hybrids have realized the satisfy results.
