In decade period from year 2000 to 2009, maize yield in Croatia varied from 4.3 t/ha (2003) to 8 t/ha (2008). Yield variation is mainly influenced by unfavorable weather conditions for maize production meaning lack of precipitation and high mean air temperatures. In addition to that, unfavorable distribution of precipitation during vegetation season leads to yield decreasing and quality distortion of maize grain. In this paper five vegetation seasons (2000, 2007, 2008, 2009 and 2010) with quite different weather conditions for maize production have been analyzed in order to examine the influence of weather conditions meaning draught, flood and irrigation practice as well (meaning soil water content) to maize production. Irrigation practice has become justified and essential agrotechnical measure which minimizes damage of water deficit during a critical growth stage of plant and it ensures high yield of maize grain but in this period of climate changes it is necessarily to maintain existing melioration systems and to invest in new one too.
