The study looked at how different types of triticale plants use nitrogen at different growth stages. They tested 31 triticale varieties with low and normal nitrogen levels. Results showed that some triticale types are better at using nitrogen efficiently than others. They found three main types: high, low, and middle nitrogen users. The high nitrogen users grew taller and had more shoot biomass than the low nitrogen users. The plant height and shoot biomass were closely linked to nitrogen use efficiency. This suggests that these traits can be used to predict how well triticale plants use nitrogen.
