INFLUENCE OF DROUGHT ON MAIZE YIELD REDUCTION (Zea mays L.)

Cilj ovoga rada bio je istražiti utjecaj vremenskih prilika, prvenstveno oborinski i temperaturni režim, na urod kukuruza u razdoblju od 2000. – 20014. godine. Urod kukuruza bio je u rasponu od 4,1 t/ha do 8,1 t/ha. Varijacije uroda rezultat su nepovoljnih godina u pogledu vremenskih prilika. Prvenstveno u količini ali i u rasporedu oborine. Najniži urodi zrna kukuruza zabilježeni su u godinama s ispodprosječnom količinom oborine i nadprosječno visokim temperaturama zraka. Najizraženiji pad uroda je u godinama kada se sušno razdoblje javlja u mjesecu lipnju i srpnju.The main goal of this paper is to study the influence of weather conditions to maize grain yield. The tested period is from year 2000 to 2014. Maize grain yield ranged from 4.1 t/ha to 8.1 t/ha. Yield variation came as a result from unfavourable years for maize production, mainly the lack of precipitation as well as unfavourable distribution of precipitation and air temperatures above the long term mean. Yield reduction was considerably higher in growing seasons with dry June and July
