Trials were conducted in the Institute of Plant Protection in Poznan. Aim of the experiments was evaluation of trinexapac-ethyl used on different nitrogen fertilization level. The objectives of the experiment was winter triticale cv. Fidelio. Trineksapak ethyl (TE) was applied in alone in two doses 75 g a.i. . ha-1 and 125 g a.i. . ha-1 and in a mixture with chlorocholine chloride (CCC) in dose 50 g a.i. . ha-1 (TE) + 675 g a.i. . ha-1 (CCC) on three nitrogen fertilisation levels. 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 such measurements as stem length, ear length, and internode length, stem diameter, the 3rd internode diameter and chlorophyll content. Results confirm that influence of trinexapac-ethyl on winter triticale is changing depending on nitrogen fertilisation dose. Interaction between experimental factors was strongly determined by meteorological conditions during the vegetation season.
