abstract:
Two cultivars of rye, i.e. Amilo and Esprit from a field experiment made at the University of Warmia and Mazury in Olsztyn, were used in the study. Six nitrogen fertilization doses, from 0 to 150 kg N ha-1, added at tree development stages, i.e. prior to seedling, tillering, and 3rd node, were studied for the differences in the falling number, protein and ash contents in whole kernel and flour. An advantageous influence of N fertilization on both grain and flour quality was noted for the two cultivars under examination. The protein content and falling number increased with the rise of nitrogen dose, whereas the ash content decreased.
