Abstract

The aim of this work was to assess the effect of different application rates of NPK fertilizer on the productivity of winter triticale varieties in podzolic soils. In this particular study, 3 varieties of winter triticale: Guera, Nemchinovskaya 56, and Nina were evaluated in 2020-2022 on the experimental fields of FIC "Nemchinovka". The best response to mineral nutrition was observed in the Guera variety, which was also more resistant to lodging under the conditions during the trial period (2020-2022). The grain yield per hectare as a function of the application rates ranged from 6.75 to10.78 tons for the Guera variety, 5.65 to 8.84 tons for the Nemchinovskaya 56 variety, and 4.87 to 8.61 tons for the Nina variety. For two years, the average yield increase in comparison with the control was obtained by varieties through increment of NPK rates as demonstrated by the treatment percentile increases for each variety: Guera-T1-14, T2-25, and T3-56%; Nina-T1-19, T2-41 and T3-60%; and Nemchinovskaya 56-T1-22, T2-44, and T3-77%. Similarly, the application of T3 to the triticale varieties increased crude protein by 37% in Guera, 64% in Nemchinovskaya 56, and 46% in Nina variety compared with the control.

Key words: Mineral fertilizer, winter triticale, yield, podzolic soil, application rates.
