Efekti različitih vremenskih prilika na urod hibrida kukuruza raznih FAO grupa
Four maize hybrids (OsSK 373, OsSK 444, OsSK 552 and OsSK 602) had been grown in field trials at three sites in Eastern Croatia (Vukovar = VU, Osijek = OS and Beli Manastir = BM) during three climatically very different years (precipitations in period June-August: 472 mm, 254 mm and 160 mm for years 2005., 2006. and 2007., respectively for sites VU, OS and BM). Average maize grain yields were 10620, 10700, 6674 and 9846 kg ha -1 in years 2005, 2006, 2007 and 2008, respectively, whereas hybrids had 9892, 9069, 8987 and 9893 kg ha -1 for OsSK 373, OsSK 444, OsSK 552 and OsSK 602, respectively. Regarding its genetic potential, the unfavourable weather conditions decreased the most yield of OsSK 552, whereas the highest stability showed OsSK 444.
