Trials were conducted in the Institute of Plant Protection in Poznan. Aim of the experiments was evaluation of trinexapac-ethyl used on different nitrogen fertilisation level. The objectives of the experiment was winter triticale cv. Fidelio. Trineksapak ethyl (TE) was applied in two doses 75 g a.i. . ha-1 and 125 g a.i. . ha-1 and nitrogen fertilisation was applied in 0 kg N . ha-1, 80 kg N . ha-1 and 160 (80 + 80) kg N . ha-1. Evaluation contains: weight of 1000 grains, number of grains in ear, protein content and yield. Results confirm that yield structure components and protein content of winter triticale are influenced by retardants and nitrogen fertilisation interaction. Changes in yield structure components and protein content in winter triticale were highly dependent on weather conditions during the vegetation seasons.
