Yield components and yield of winter wheat in different years of research

Abstract

Field trial with wheat varieties Perfekta, KG 56S, Aleksandra and Vizija was set on vertisol-type soil during the vegetation season 2010/11 and 2011/12. The aim of the research was to analyse the yield and grain yield components in four varieties of wheat cultivated on acid soil. The highest values of yield components and grain quality were established in the year with moderate temperatures and high precipitation in the vegetation year 2010/11. The KG 56S and Vizija varieties had the highest yield of grain, the highest number of plants and spikes per m2. The Perfekta variety showed the highest 1000 grain weight and grain weight per spike. The highest number of grains in the spike and the lowest average yield of grain during the research were recorded for the variety Aleksandra. A significant positive correlation between grain yield and grain weight per spike, the number of grains in the spike and the number of plants per m2 were established, as well as between the 1000 grain weight and the number of grains in the spike and the grain weight per spike.

Poljski ogled sa sortama pšenice Perfekta, Kg 56S, Aleksandra i Vizija postavljen je na zemljištu tipa vertisol tokom vegetacionih sezona 2010/11 i 2011/12 godine. Cilj istraživanja je bio da se kod četiri sorte pšenice gajene na kiselom zemljištu analizira prinos i komponente prinosa zrna. Najveće vrednosti komponenti prinosa i kvaliteta zrna ustanovljene su u godini sa umerenim temperaturama i velikom količinom padavina u vegetacionoj 2010/11 godini. Sorte KG 56S i Vizija imale su najveći prinos zrna, najveći broj biljaka i klasova po m2. Sorta Perfekta odlikovala se najvećom masom 1000 zrna i masom zrna po klasu. Najveći broj zrna u klasu i najmanji prosečan prinos zrna tokom istraživanja imala je sorta Aleksandra. Ustanovljena je značajno pozitivna korelacija između prinosa zrna i mase zrna po klasu, broja zrna po klasu i broja biljaka po m2, kao i između mase 1000 zrna i broja zrna po klasu i mase zrna po klasu.
