Abstract
Spring triticale cv. Andrus was cultivated in 2010 and 2011 with the application of different combinations of nitrogen fertilization with a total dose of 80 or 120 kg ha-1. The nitrogen fertilizer was applied into soil or both into soil and on leaves (foliar application) with and without microelements. The average grain yield was 6.21 t ha-1 with a range from 5.89 to 6.64 t ha-1 depending on the variant of fertilization. The average protein content at the dose of 80 and 120 kg N ha-1 was 14.43 and 14.74 g per 100 g of grain, respectively. A higher dose of nitrogen resulted in an increase of albumins with globulins and w and a/b prolamins in grain. This indicates that, even though some variants of fertilization with nitrogen favored the accumulation of protein in the grain, it was mainly the content of monomeric proteins that increased. The increase in their mass, due to a significant predominance in triticale grain, is undesired for potential use in baking. It suggests a lack of possibility for improvement of baking properties in triticale grain as a result of tested variants of fertilization. Key words: Triticale, nitrogen fertilization, glutelins, prolamins.
Highlights
Triticale is a hybrid cereal plant derived from wheat and rye genomes

The increase in their mass, due to a significant predominance in triticale grain, is undesired for potential use in baking.

This paper discusses the impact of nitrogen fertilization applied at doses of 80 and 120 kg ha-1 into soil and into both soil and foliarly, with and without multi-component fertilizers as well as the impact of the year of harvesting on the yield of grain and protein and its composition in spring triticale grain
Summary
A higher dose of nitrogen resulted in an increase of albumins with globulins and and / prolamins in grain. This indicates that, even though some variants of fertilization with nitrogen favored the accumulation of protein in the grain, it was mainly the content of monomeric proteins that increased. The increase in their mass, due to a significant predominance in triticale grain, is undesired for potential use in baking.
