A strict field experiment was established in 1988 at the Uhrusk Experimental Station, belonging to the University of Life Sciences in Lublin, south-eastern Poland. Results presented in this manuscript originate from the years 2006-2009, namely from 5 crop rotations and from a 16-20-year cereal monoculture. In a two-factor experiment, spring wheat of the cultivar Opatka was sown in different cropping systems. The first order factor in the experiment was the cropping system (CS): crop rotation (CR), and monoculture (M), whereas the second order factor were nitrogen doses: 90 kg N ha–1, and 150 kg N ha–1. The study demonstrated that wheat grain collected from CR was characterized by higher content of P, Ca, Fe and Zn compared to the grain harvested from M. Fertilization with 90 kg N ha–1 increased significantly the content of P, K, Ca, Fe and Zn in the grain compared to the fertilization with 150 kg N ha–1. The cropping systems (CS) and nitrogen doses were observed to differentiate the content of protein and gluten in the grain. A higher content of protein was determined in the grain originating from M than in the grain harvested from CR. The content of protein and gluten was increased by the fertilization dose of 150 kg N ha–1 compared to the dose of 90 kg N ha–1.
