Sažetak
Weather characteristics considerably influencing factor on field crop yields and yield variation among years. The harvested areas (4-year means 2007-2010) of main spring field crops in Croatia were 299838 ha (maize), 45647 ha (soybean), 25596 ha (sugar beet) and 28153 ha (sunflower). Variation of yields among the years were relative high, especially for maize and soybean, because the lowest yield in 2007 was for 38% (maize) and 35% (soybean) lower than the highest yield realized in 2008. Analogical comparison for remaining two tested field crops was, 26% and 20% for sunflower and sugar beet, respectively. The 2007 growing season was unfavorable for spring crops growing in Croatia because of water shortage and higher air-temperatures. For example, precipitation in April-September period of 2007 in Osijek was 229 mm only or for 40% lower and air- temperature for 1.5 oC higher than LTM (long- term mean 1961-1990). Water deficit was especially in June and July because of only 60 mm precipitation or for 60% lower and the higher air-temperature for 2.8 oC in comparison with LTM. At the same time, in western part of the region water shortage was lower (for example Zagreb: 9% and 20% lower precipitation in April-September and June-July periods). Remaining three tested years, especially 2008, were more favorable for spring crops growing in Croatia because of adequate precipitation and temperature regimes.
