| Abstract | Objective. To determine the formation of yield and grain quality of winter triticale under various types and doses of fertilizers. Methods. Field, measuring, calculation-comparative, analytical, and statistical methods. Results. In these variants, the yield increased only up to 9.97–10.17 t/ha, which is 6–8% less compared to the application of N120. The yield from the application of phosphorus and nitrogen fertilizers, as well as potassium and phosphorus fertilizers, was only 2–6% lower than with full fertilizer application. The smallest effect on grain yield of winter triticale was observed from the application of phosphorus and potassium fertilizers – 8.88 t/ha, or 4% more than the control. The yield of the winter triticale line LP 154 was at the level of the Ajax variety – 8.49–11.17 t/ha depending on fertilization. The trend of fertilizer application effects, both on average and across the years of research, was similar to that observed for the Ajax variety. For the Ajax variety, the protein content increased from 10.0% without fertilizers to 11.0% with full mineral fertilization – an increase of 10%. On average over three years, only the application of N60 S35 + N60 resulted in 11.3% protein content – 3% more than with a single application of nitrogen fertilizer. The grain of the Ajax winter triticale formed 19.8 to 23.0% gluten. Over three years, gluten content increased by 11% with the Background + N120 treatment compared to the control. In the Background + N60 S35 + N60 treatment, gluten content increased by 5% compared to a single nitrogen application. It is important to note that phosphorus and potassium fertilizers had the least impact on gluten content. Gluten content in the grain of the LP 154 winter triticale line was 7–9% higher compared to the Ajax variety. At the same time, the effectiveness of different fertilizer types and the influence of weather conditions were similar to those for the Ajax variety. Conclusions. Under the conditions of the Right-Bank Forest-Steppe of Ukraine, the studied winter triticale cultivars demonstrate high productivity. The highest yield efficiency was observed with the one-time application of N120 on the background of P60K60. It is worth noting that nitrogen fertilizers can be applied temporarily within the winter triticale fertilization system. Regarding protein content, the LP 154 line is superior when grown under conditions favorable for high nitrogen compound synthesis. In less favorable years, the protein content in the four-species triticale line is at the level of classical varieties. Additionally, the effectiveness of sulfur-containing fertilizers also varies depending on weather conditions during the growing season. | ||
