Sažetak
This study evaluates maize yield variations in the Autonomous Province of Vojvodina (Serbia) and Eastern Croatia (Croatia) over a period of eight years. The effect of precipitation and mean air temperatures on maize yields was analysed during June through August, using the weather data issued by the State Hydrometeorological Institutes based in Belgrade (Serbia) and Zagreb (Croatia). Data on total acreages and average yields of maize were obtained from the Serbian and Croatian Statistical Yearbooks (2000-2009). The analysis covering the eight-year period showed that the years 2000 and 2003 were highly unfavourable for maize production (the twoyear yield average in Vojvodina and Eastern Croatia being 3.1 t ha-1 and 3.9 t ha-1, respectively), as opposed to the two “favourable” years (2005 and 2006) giving an average of 6.2 t ha-1 (Vojvodina) and 6.7 t ha-1 (Eastern Croatia). During the June- August period, the measured precipitation values for the “unfavourable years” averaged 91.5 mm in Vojvodina (Novi Sad) and 112 mm in Eastern Croatia (Osijek), with the average air temperatures in the respective regions being 23.1ºC and 22.9ºC. The corresponding data for the “favourable years” were 326 mm and 380.5 mm, and 20.5ºC and 21.1ºC, respectively. The long-term average values (1961- 1990) of precipitation and air temperatures measured over the three summer months were similar for Novi Sad (207 mm and 20.4ºC) and Osijek (211 mm and 20.3ºC).
