Weather conditions in the 2013-2015 wheat growing season in Croatia and Bosnia and Herzegovina

Winter wheat is a very important field crop on the arable lands in Croatia and Bosnia and Herzegovina (B&H).Wheat production is often characterized by significant yield variations, as affected by unfavorable weather conditions. The aim of this study was to analyze wheat yield in relation to weather data (precipitation and mean airtemperature) in Croatia and B&H in the 2012/2013, 2013/2014 and 2014/2015 growing seasons.The data from four meteorological stations in Croatia situated in the east and north of the country and data from four stations in the northern B&H were analyzed. Average wheat yields were 4.9, 4.2 and 5.4 t ha-1 (Croatia), and 3.9, 2.9 and3.5 t ha-1(B&H), for harvest in 2013, 2014 and 2015, respectively.The 2013/2014 growing season was less favorable for winter wheat growingas precipitationsums in the October-June period were considerably higher compared to the long- term reference mean (1961 – 1990), while mean air temperatures were significantly higher. The main cause of lower yields in 2014 for both countries was excessive precipitation in the period April-June, in some places also accompanied with floods. In the remaining two growing seasons, precipitations in both countries were mainly favorable distributed and temperatures somewhat lower compared to the 2013/2014 season.
