Sažetak

Aiming to determine desiccation impact on seed moisture and yield, impurity, oil content and sunflower price, in ordinary and stubble sowing (after chamomile and winter barley) field trials were set up on the areas of Bioagrar Ltd. company Ivanovci (Valpovo ) in 2008 and 2009. Six sunflower hybrids: LG 53.80M (2008), LG 54.12 (2009), Brio, LG 56.65M, Apolon, Šokac and OS-H-13 were used in the trials in ordinary sowing of 2008 and 2009 while in stubble sowing of 2008 hybrid LG 53.80M was sown, and in 2009 hybrid LG 54.12. Reglone forte [diquat] (3 l/ha) and Harvade 25F [dimethipin] (2 l/ha) were used as desiccants applying 500 l water / ha. Desiccation was done by pulled tractor sprayer of 18 m working width. In these researches, desiccation was very useful agro-technical measure which considerably accelerated sunflower maturation, especially in a stubble sowing, and reduced presence of weeds. This, in turn, enabled earlier, easier and faster harvesting,
and earlier field preparation for the next crop sowing. Regarding sunflower prices, desiccation is profitable in wet weather years.
