The impact of climate change on barley yield

Poljski ogled sa sortama Rekord, Maksa i Grand postavljen je na zemljištu tipa vertisol tokom vegetacionih sezona 2006-2010 godine. Cilj istraživanja je bio da se kod tri sorte ozimog ječma gajenih na kiselom zemljištu analizira prinos zrna. Najveće vrednosti prinosa zrna ustanovljene su u vegetacionoj 2007/08 godini (5.788 t ha-1). Prosečan petogodišnji prinos zrna kod ispitivanih sorti kretao se od 4.654 t ha-1 do 5.207 t ha-1. Sorta Maksa imala je najveći prinos zrna. Na osnovu analize varijanse, može se zaključiti da postoje vrlo značajne razlike u prinosu zrna u odnosu na godinu ispitivanja.Field trial with barley varieties Rekord, Maksa and Grand was set on vertisoltype soil during the vegetation seasons 2006-2010. The aim of the research was to analyse the grain yield in three varieties of barley cultivated on acid soil. The highest values of grain yield were established in the vegetation year 2007/08 (5.788 t ha-1). The average of five-year grain yield of barley cultivars ranged from 4.654 t ha-1 to 5.207 t ha-1. The Maksa cultivar had the highest yield of grain. Based on the analysis of variance, it can be concluded that there are very significant differences in grain yield regard the year of investigation, while among the investigated barley cultivars the differences were very significant
