Opis:
The aim of the present study was to evaluate the effect of chemical crop protection on the content of N, P, K, Mg, Zn, Cu, Mn, and Fe in grain of 8 spelt wheat cultivars (Franckenkorn, Badengold, Schwabenspelz, Oberkulmer Rotkorn, Ostro, Ceralio, Schwabenkorn, and Spelt I.N.Z.). Chemical protection involved application of a fungicide, two herbicides and a retardant. No plant protection agents were used in the control treatment. The above spelt cultivars were grown in a monoculture on medium heavy mixed rendzina soil. The study was carried out in 2009-2011, at the Bezek Experimental Farm, which belongs to the University of Life Sciences in Lublin. Among the spelt wheat cultivars compared, grain of cv. Ostro was characterized by the highest content of nitrogen, phosphorus and manganese, whereas grain of cv. Franckenkorn contained the largest amounts of potassium and magnesium. The highest amount of zinc was found in grain of cv. Oberkulmer Rotkorn and that of copper – in grain of cv. Spelt I.N.Z., while grain of cv. Schwabenkorn was found to be the richest in iron. Irrespective of the cultivar, chemical plant protection significantly increased the copper content in spelt grain and simultaneously decreased the magnesium content. The content of N, Mg, Zn, Cu, and Mn in grain decreased in the successive years of the study.

Opis:
The aim of this study was to determine the effect of the level of agronomic practice on the content of N, P, K, Mg, Zn, Cu, Mn, Fe and Ca in linseed seed cultivars (cv. Szafir and Oliwin) sown at a row spacing of 15 cm or 25 cm. A field experiment was carried out in 2010–2012. on mixed rendzina soil. The agronomic practice applied differed in the dosage of nitrogen (40, 60 or 80 kg N ha-1) and in weed control (A. without herbicides; B. with two herbicides, C. with three herbicides). The cultivar Szafir was characterised by a significantly higher content of nitrogen than cv. Oliwin, which in turn had a higher manganese content. The content of potassium, magnesium, zinc and manganese in seeds was higher when flax was sown at the narrower row spacing (15 cm) compared to the 25 cm row spacing. A similar relationship was determined for nitrogen, iron and calcium, but statistical verification did not confirm the significance of these differences. The level of agrotechnology in linseed crop cultivation did not influence the seed concentration of the elements. A slightly higher content of the elements in seeds was detected in the treatments where extensive (40 kg N ha-1, without herbicides) and medium intensive technology (60 kg N ha-1, Linurex 50 WP, Fusilade Forte 150 EC) were used, compared to intensive technology (80 N ha-1, Linurex 50 WP, Fusilade Forte 150 EC, Glean 75 WG). A slightly higher content of Fe and Ca was determined in seeds harvested from the plots where the intensive technology was used. Weather conditions significantly affected the content of K, Mg, Zn and Mn in linseed seeds
