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.
