| Abstract | Objective. To determine the productivity formation of winter triticale under different nitrogen fertilizer rates, foliar feeding, and senication. Methods. Field, measurement, calculation-comparative, analytical, and statistical methods. Results. When 30 kg/ha of active substance was applied as foliar feeding with urea, the yield of winter triticale increased by only 2–4 %. Yield increase from nitrogen fertilizer application at rates of 30–120 kg/ha a.s. was 9–26 % compared to the no-fertilizer control. It is worth noting that phosphorus and potassium fertilizers increased yield by only 1–2 %. The study results show that senication without foliar feeding with urea had virtually no effect on winter triticale grain yield compared to plots without senication – 5.49–6.84 t/ha. When foliar feeding was applied, the yield increase from senication was only 1 % compared to untreated plots, which was not statistically significant. The protein content in winter triticale grain, averaged over two years, increased from 8.8 % (control) to 9.3–9.5 % with the application of N90–120. Foliar feeding with urea increased protein content by 5–11 %. Senication without foliar feeding raised this figure by 1–3 %, while with foliar feeding – by 10–19 % compared to surface-applied nitrogen fertilizers. Conclusions. The yield and protein content in winter triticale grain are affected by different nitrogen fertilizer application methods. The most significant yield increase was achieved with the application of 60–90 kg/ha a.s. of nitrogen fertilizers. Foliar feeding with urea and senication did not have a statistically significant impact on grain yield. Depending on weather conditions, yields ranged from 4.72–6.25 to 5.31–8.31 t/ha. In the fertilization system for winter triticale, the most effective is the use of N60–90 in combination with foliar feeding with urea at a rate of N30. This fertilization system ensures yields of 5.36–8.50 t/ha with a grain protein content of 10.0–11.5 %, depending on the weather conditions during the research years. | ||
