Sažetak
The aim of this study was to test the impact of monthly precipitation and temperature regimes on winter wheat yields in Bosnia and Herzegovina (B&H) for the last 15-year period (2000-2014) with an emphasis on its administrative parts Federation of B&H (FB&H) and Tuzla Canton (TC: from 2005-2014 period). Winter wheat is an important field crop in B&H, but yields are low, (average of 3.24 t ha-1) with very high variation among years (from 2.26 to 3.92 t ha-1). We estimated that yield differences are mainly due to weather variability. Average temperature in Tuzla (October-June) was 8.3°C in the last 15 years or 0.9°C higher than the 1 961-1990 and 1925- 1940 averagesPrecipitation close to the 30-year average (663 mm, 642 mm and 636 mm) and their balanced monthly distribution characterized three growing seasons favorable for wheat (2007/2008, 2008/2009 and 2012/2013, respectively). Also, the temperature regime was without excessive cold or warm periods in these years. Under these conditions, wheat yields were considerably higher (3.7, 3.8 and 3.9 t ha-1, respectively) than in three estimated unfavorable years (2002/2003, 2009/2010 and 2013/2014 with 2.3, 2.7 and 2.9 t ha-1, respectively). Weather deviations as either drought or excessive precipitation in combination with high temperatures characterized estimated less favorable years. Tuzla Canton had about 5% of the national wheat harvested area, whereas yields were somewhat higher compared to the country average. Although it is evident that yields of wheat and weather conditions in B&H are very different between years, by performing simple correlation analysis there was found a minimal connection of precipitation and temperature with yields. Significant negative correlations were found only in level TC between yields and monthly values of precipitation in April (-0.88**), May (-0.70**) and total precipitation (-0.73**). Also, significant positive correlations were found between April (0.76**) and May (0.62*) temperature and yields.
