The aim of the study was to investigate the productive possibilities and the structural elements of the yield depending on the variety, the applied fertilizer rate and the import of foliar treatment for winter triticale. The study was conducted in 2019/2020-2020/2021. Colorit, Attila and Boomerang varieties were tested. Nitrogen fertilization was at rates: 0; 60 and 120 kg ha-1. A foliar treatment was performed in the tillering and stem elongation phases. Mineral fertilization was a major impact on the values of all studied parameters and only for the number of grains per spike the variety has a stronger influence. The rate of 120 kg N ha-1 was the most productive for the observed traits. The foliar treatment was a stronger effect in the stem elongation phase, except for the plant height, where no differences were found between the two phases. Boomerang was the highest grain yield (45.0%), plant height (23.3%) and number of spikelet per spike (11.5%), Attila was the longest spike (23.4%), and Colorit was the highest number and heaviest grains per spike, 37.9% and 51.72%, respectively, compared to control.
