Spring triticale productivity at different doses of nitrogen fertilizers

Mineral nutrition improvement contributed signifcantly to spring triticale grain yield. On average, during the two years of research, use 30–210 kg/ha active ingredient nitrogen fertilizers increased it 6.50–8.36 t/ha or by 14–46 % compared unfertilized plots (5.71 t/ha). The stability index yield formation was high – 0.92–0.95. Weather conditions in research were different. precipitation level April June 2014 made 442.7 mm, and 2015 87.5 mm. In 2014, application N30–210 0.81–2.66 t/ha, 0.77–2.64 no fertilizer variant. It is worth noting that phosphorus–potassium provided 0.30–0.32 t/ha. protein content grain.
