The study looked at different types of wheat grown on acidic soil to see how stable their production was. They tested five varieties over two years and found that the amount of grain produced varied between years, with higher yields in 2006/07. One variety, Ana Morava, had the highest yield in the second year. The weight of 1000 grains also varied between varieties, with some being heavier than others. The quality of the grain and its weight were both influenced by the type of wheat grown. Overall, the type of wheat had a significant impact on the weight of 1000 grains.
