Abstrakt:

Researchers from the Siedlce University of Natural Sciences and Humanities carried out an investigation in 2017-2019, on a family farm located in Krzymosze (52° 03’ 27’’N, 22° 33’ 74’’E) near Siedlce, Poland, aiming at determining the effect of biofertilisers and nitrogen fertiliser regime on the protein content as well as macroelements in the grain of spring wheat produced in a sustainable agriculture system. The following two factors were examined: (I) biological preparations: control where no biological preparations were applied, Azotobacter vinelandii, L-α proline, Azotobacter vinelandii + L-α proline; (II) mineral nitrogen regime: unamended control, 60 kg N ּha-1, 90 kg N  ּha-1, 120 kg  Nּ ha-1. Spring wheat grain was sampled to determine the total protein content and macroelements (P, K, Ca and Mg). The results demonstrated that the biological nitrogen preparations Azotobacter vinelandii + L-α proline applied simultaneously with 90 kg Nּ ha-1 contributed to the production of spring wheat grain with the highest concentration of protein and phosphorus, potassium, calcium and magnesium, all being very important in human nutrition. The use of the biological preparation Azotobacter vinelandii and L-α proline biostimulator with a fertilisation dose of mineral nitrogen of 90 kg N ha-1 ensures favorable chemical composition of spring wheat grain. Moreover, such form of fertilisation protects the soil environment, an issue of growing importance in modern agriculture. It should be recommended to apply bioproducts in combination with lower nitrogen mineral fertilisation doses in spring wheat cultivation.
