Abstract
Research related to fertilization in winter triticale cultivation was limited to macroelements. The effects of boron on triticale (deficiency or toxicity) affecting productivity are still unknown. In 2013–2015, a field experiment was carried out at the Experimental Station in Tomaszkowo near Olsztyn. The objective was set response of winter triticale variety Pigmej under the influence of various levels of nitrogen (N) and boron (B) fertilization. Five levels of nitrogen fertilization: 0, 40, 80 (50 + 30), 120 (90 + 30), and 160 (90 + 70) kg ha−1 and four levels of boron fertilization: 0, 0.8, 1.6, and 2.4 kg ha−1 were tested. The experiment has demonstrated considerable differences in the grain yield volume and structure under the influence of various weather conditions and different doses of nitrogen. The difference between the highest and lowest grain yield was 1.7 t ha−1—53.6%. The effect of boron application was also manifested as an increase in the winter triticale grain yield and improved yield component structure, but the statistically significant differences were observed only in ears number per 1 m2. The highest dose of boron applied in the experiment caused a decrease in the quantity of grain yield and its component parts.
