Different cropping systems and application of diverse fertilizers in ecological production can
affect soybean grain composition. From that point of view, experiment with red grain maize
variety (Rumenka) and black grain soybean (Dukat) was carried out. Three treatments were
applied: single crop (SC), alternating rows of both crops (AR) and alternating strips (3 rows of
each species - AS). Fertilization regimes included fertilizers: Ofert (organic fertilizer), Uniker
(microbiological fertilizer), urea and control (without fertilization). Both crops achieved the
highest grain yield in AR and AS, in Uniker treatment. All applied fertilizer regimes increased
mineral nutrient’s content, compared with control. Uniker increased average K content, up to
12%, while Ofert increased average contents of Ca, Mg and Zn, up to 9, 6 and 22%, respectively.
As opposed to applied organic and microbiological fertilizers, urea increased average contents of
Fe, Cu, Mn and P, up to 10, 18, 16 and 4%, respectively. The positive impact of Ofert on
soybean grain quality was also evident in increase of average antioxidants content: total phenolics
and glutathione, up to 11 and 5%, respectively. Among all cropping systems, AR treatment
induced slight increase of grain yield, together with average Ca and K contents. AS treatment
showed positive effect on Mg, Zn and P accumulation, as well as increase of total phenolics and
glutathione. On the other hand, SC was more effective for Fe, Cu and Mn accumulation.
Preliminary results of tested cropping systems, which could enable better utilization of space and
nutrients, indicated variations in soybean grain quality.
