Maize cultivation with application of proper organic and bio-fertilizers could increase
nutritional value of crop grain and maintain soil fertility. The aim of the study was to examine
variations in concentrations of phytate, soluble phenols, total glutathione (GSH), yellow
pigment (YP), DPPH radical scavenging capacity (DPPH), Ca, Mg, Fe, Zn and Mn in maize
hybrids with white, yellow and red colour grain, under the influence of bio-, organic fertilizer
and urea in regard to control (without fertilization). Results indicated that phytate, DPPH, Ca,
Mg and, Mn varied slightly (< 10%). Red grain maize was characterized with the highest
concentrations of phenols, Ca, Mg, Fe, Zn, and DPPH. White grain maize, particularly in urea
and bio-fertilizer treatment, accumulated higher GSH values, while red and especially yellow
grain hybrid accumulated higher YP amount in urea treatment. Irrespective to lower variations
in Mn concentration, higher values were determined in yell...ow hybrid. Organic fertilizer
mainly induced increase in Mg bio-fertilizer which positively affected Fe accumulation, while
urea caused higher Zn and Mn accumulation in maize grain. It could be concluded that yellow
and particularly red grain hybrid enabled increased accumulation of mineral elements,
together with higher DPPH values, mainly in treatments with organic fertilizer and urea
giving it advantage in production of highly nutritious food.
