Abstrakt:

The management of nutrients in wheat cultivation should take into account the demand for N and other nutrients. A field experiment involving the cultivation of winter wheat was carried out in the years 2013-2016 at the Educational and Experimental Station of the University of Warmia and Mazury in Tomaszkowo (53°72 N; 20°42 E), Poland. The aim of the study was to assess the effects of fertilisation with two nitrogen doses (150 and 200 kg ha-1) and three manganese doses (0.5, 1.0 and 1.5 kg ha-1) on yield components, crop productivity, macronutrient content and technological indicators for grain (protein, gluten and starch contents, Zeleny sedimentation index, hardness and bulk density of grains). Nitrogen fertilisation (150 and 200 kg ha-1) and foliar Mn spraying (0.5, 1.0 and 1.5 kg ha-1) had no clear effect on grain yields, technological quality indicators, selected biometric features or the yield components, and the expected results were distorted by the changeable weather conditions. On average, regardless of Mn application, a higher nitrogen dose increased the protein and gluten content as well as the Zeleny index value in the first and the second year of the study. Under the influence of the higher N dose, the Ca content of grains increased; however, it was only statistically confirmed in the first and third year of the study. An increase in nitrogen fertilisation in variants with different Mn doses and without its application promoted an increase in the protein and gluten content, yet it was only statistically confirmed in the first year of the study. An increase in nitrogen fertilisation from 150 to 200 kg ha-1 as well as additional Mn spraying did not significantly differentiate the P, K and Mg content of wheat grains.
