The study looked at four different types of winter barley to see how they grew in a specific type of soil. They found that the barley types had differences in how much grain they produced, how tall they grew, and how well the seeds germinated. The weather each year also affected how much grain the barley produced. Some barley types had lower grain weight in the first year but increased in the following years. Overall, the study showed that different barley types can perform differently depending on the growing conditions.
