Content of minerals in grain of spring wheat cv. Koksa depending on cultivation conditions

A study has been undertaken to determine the effect of different cultivation conditions for spring wheat cv. Koksa on the total ash, P, K, Mg, Ca, Fe, Zn, Mn, and Cu in wheat grain. The study was conducted at Uhursk Experimental Farm (51°18’12"N, 23º36’50"E) of the University of Life Sciences in Lublin, in 2008-2010. The experimental factors were: 1) systems of soil tillage: ploughing and ploughless, 2) doses of nitrogen: 90 and 150 kg ha–1, and 3) preceding crop: pea and soy. The objective was to evaluate the impact of different soil tillage systems, doses of nitrogen fertilizers and preceding crops on the content of mineral components in the grain of spring wheat cv. Koksa. The study demonstrated that ploughless tillage increased the content of total ash, Zn and Cu, while ploughing tillage raised the content of K, Mg and Mn in the grain. A standard dose of nitrogen (90 kg ha–1) facilitated the accumulation of K, Fe, Zn and Cu, whereas a higher nitrogen dose (150 kg N ha–1) elevated the content of total ash and Mn in grain of spring wheat. The grain of wheat cultivated after pea was characterized by a higher content of Ca, Fe and Zn, whereas that cultivated after soy contained more total ash, K and Mn.
