Sažetak
Aim of this study was appreciation of the 2009 growing season with aspect of spring crops growing in Pannonian region of Croatia and its comparison with favourable 2005 and unfavourable 2007. With that regard, precipitation and air-temperature regime impacts were focused. Total six weather bureaus were used as source of weather data as follows: Osijek, Gradište (near to Zupanja) and Slavonski Brod situating in Eastern Croatia ; Bjelovar, Sisak and Zagreb-Maksimir situating in Central Croatia. Precipitation in the April-September period of 2009 was 306 mm (mean of six tested localities of the region) or 31 % lower in comparison with long-term mean (LTM) 1961-1990 (442 mm) but at same time air-temp. was for 2.4 oC higher (19.5 oC and 17.1 oC, respectively). However, weather characteristics in July and August have especially effects on spring crops growing. In general, water deficit in combination with higher air-temp. have detrimental effects. Precipitations in July+August of 2009 (means of three representing localities) were 81 mm (LTM = 140 mm) and 152 mm (LTM = 166 mm), for Eastern Croatia and Central Croatia, respectively. At the same time mean air-temp. were 23.0 oC (LTM = 20.5 oC) and 22.5 oC (LTM = 20.0 oC), respectively. These data are indicator of less favorable weather conditions in 2009 for spring crops growing. Comparison of weather characteristics in two recent growing seasons is a typical example degree of their favorability. Under favourable weather conditions of the 2005 growing season, precipitation in July + August (means of six tested localities of the region) were 328 mm or more than 2 fold more in comparison with LTM (154 mm). At the same time, air-temp. was 20.4 oC (LTM: 20.2 oC). However, analogical data for the unfavourable 2007 were 95 mm or 38 % lower than LTM and it is accompanied with the higher air temp. (22.7 oC) for even 2.5 oC. As result of these differences of weather characteristics are maize yields 4.87 t/ha in 2007 or about 30% lower than in 2005 (means of six counties covering tested weather bureaus centers).
