Sažetak
Maize is main field crop on the arable lands in Croatia and Serbia. The harvested areas of maize in 2003-2012 were in Croatia 313918 ha and in Serbia 1216786 ha or about third part of total arable lands. The annual yield variations among the years were from 3.86 to 8.00 t ha-1 in Croatia and from 3.2 to 6.7 t ha-1 in Serbia. The general statement that the lower maize yields is in connection with the lower precipitation and the higher air-temperatures, especially in July and August. The highest yields of maize were in 2010 both in Vukovar- Syrmium County and Vojvodina (8.00 and 6.7 t ha-1, respectively) and they are mainly result of adequate precipitation in July and August (143 mm in Osijek and 150 mm in Sremska Mitrovica) and the lower temperatures (22.4oC and 22.7oC, respectively). Also, the lowest yields in 2012 (3.80 t ha-1 and 3, 2 t ha-1, respectively) were associated with drought (52 mm and 40 mm, respectively) and high air- temperatures (24.5 and 24.7oC, respectively). Estimated yields of maize in 2012 for Croatia 4.2 t ha-1 and Serbia 3.12 t ha-1 are lower in comparison with the yields in the favorable 2010 growing season for about 40%.
