The impact of climate change on the grain yield of wheat

Poljski ogled sa sortama pšenice Takovčanka, Planeta, Kruna, Toplica i Vizija postavljen je na zemljištu tipa vertisol tokom vegetacionih sezona 2005/06-2011/12. godine. Cilj istraživanja je bio da se kod pet sorti pšenice gajenih na kiselom zemljištu analizira prinos zrna. Najveće vrednosti prinosa zrna ustanovljene su u godini sa umerenim temperaturama i velikom količinom padavina u vegetacionoj 2007/08. godini. Prosečan prinos zrna sorti pšenice kretao se od 3.743 t ha-1 do 6.275 t ha-1. Sorte Kruna, Planeta i Vizija imale su najveći prinos zrna. Na osnovu analize varijanse, moţe se zaključiti da postoje vrlo značajne razlike u prinosu zrna u odnosu na godinu ispitivanja, dok između ispitivanih sorti pšenice razlike nisu bile signifikantne.Field trial with wheat varieties Takovčanka, Planeta, Kruna, Toplica and Vizija was set on vertisol-type soil during the vegetation seasons 2005/06-2011/12. The aim of the research was to analyse the grain yield in five varieties of wheat cultivated on acid soil. The highest values of grain yield were established in the year with moderate temperatures and high precipitation in the vegetation year 2007/08. Average grain yield of wheat cultivars ranged from 3.743 t ha-1 to 6.275 t ha-1. The Kruna, Planeta and Vizija varieties 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 wheat cultivars the differences were not significant.Radovi sa 33.
