| Abstract : | The objective of the study was to determine the effect of cultivation system, plant arrangement and soybean genotype on the content of nutrients. The experiment was conducted in Czesławice near Lublin. The first factor was the system of cultivation (ecological and conventional), the second one – soybean variety (‘Aldana’ and ‘Merlin’), third – spacing of rows (35 and 22.5 cm). In samples of seed from 2016 harvest, the content of dry matter, crude protein, crude fat, crude fibre, crude ash and NFE (nitrogen free extract) was studied. Experimental systems (conventional and ecological) and row spacing (35 and 22.5 cm) did not significantly differentiate the chemical composition of soybean seeds. The varietal factor influenced the chemical composition of soybean seeds. The ‘Aldana’ soybean seeds contained significantly more crude ash and less crude fat than the ‘Merlin’ variety. Based on the study it is difficult to clearly identify the influence of agrotechnical factors on seed quality. It seems that the meteorological conditions prevailing during the growing season of a particular region of cultivation and the genotype of particular varieties appear to be decisive. |
