The Effect of Nitrogen Rates on the Growth Period of Triticale Varieties

This study investigated the effect of different nitrogen application rates on the growth period of triticale varieties. During the experiment, the main phenological stages—emergence, tillering, stem elongation, heading, flowering, and full maturity—were observed, and their duration was recorded. It was found that varying amounts of nitrogen fertilizer significantly influenced the length of the growth period. Higher nitrogen levels led to an extension of the vegetation period, while lower levels resulted in its shortening. The findings are of great importance for determining optimal nitrogen rates in triticale cultivation and for enhancing crop productivity.
