Dear producers,

Thanks to continuous progress in selection, the Agricultural Institute Osijek offers maize hybrids that are characterized not only by high yields and excellent quality, but also by adaptability to different growing conditions.

Therefore, OS hybrids are readily sown in the Republic of Croatia and in the region, as well as beyond.

You, agricultural producers and partners, have recognized the quality and contributed to a significant increase in the representation of OS hybrids of maize and their further expansion in production.

That’s why we continue to offer you top corn hybrids from different FAO groups that ensure successful agricultural production.

We are grateful for your trust and wish you high yields.

OS 3114


  • A newer early-maturity group hybrid that is widely adaptable and primarily intended for dry grain production;
  • Since becoming widely produced, it has recorded great production results in almost all localities in Croatia, as well as in Slovenia, Hungary, Romania and other countries;
  • Medium-height, robust stalk with lush leaves, characterized by high tolerance to lodging;
  • Medium-sized ears, compact and positioned at a medium height;
  • Due to its relatively short vegetation period and fast kernel dry-down during maturation, other than being suitable as a hybrid for sowing of first crops, it is also very suitable as a hybrid for early sowing of stubble crops when, during normal years (without weather extremes such as early frost, etc.), maturation occurs prior to the onset of low temperatures; the yield is then similar to the first crop.
