The effect of multi-component fertilizers on spring wheat yield, the content and uptake of macronutrients

Abstract

The aim of this study was to determine the effect of mixed multi-component fertilizers on spring wheat yield, the content and uptake of macronutrients. A three-year field experiment (2005–2007) was carried out in a randomized block design at the Research and Experimental Station in Tomaszkowo, at the University of Warmia and Mazury in Olsztyn. The experiment comprised three fertilization treatments in four replications: control treatment (simple fertilizers), Amofosmag 3 and Amofosmag 4. The tested crop was spring wheat cv. Eta. The application of Amofosmag 4 significantly increased the yield of spring wheat grain and straw. The concentrations of the analyzed macronutrients in wheat were similar in all fertilization treatments, thus pointing to a comparable effect of the applied fertilizers. More pronounced differences in the chemical composition of wheat plants were observed between successive years of the study. The highest total uptake of nitrogen, phosphorus, calcium and magnesium by spring wheat was noted in plots fertilized with Amofosmag 4, which indicates that the nutrients contained in this product were more readily available to plants.
