The negative aspects of monoculture reflect on crop, as well as soil properties. In regard to relative high maize tolerance to cropping in monoculture, different fertilization systems could positively reveal on yield and quality of produced grain. The trial with ZPSC 684 Ultra hybrid was set up, to determine efficiency of different combinations of mineral fertilizers (NPK+Urea, urea and control), bio-fertilizer (Bioplug preparation) and farmyard manure on grain yield and concentration of mineral elements (N, P, K, Ca, Mg, Fe and Zn) in grain of maize grown in long-term monoculture. Results signify that manure showed positive effects on grain yield increase and concentration of micro- and macro-elements in maize grain. Bioplug, as preparation that intensify mineralisation of crop residues expressed positive effects on accumulation of N, Mg and Fe in maize grain. NPK+Urea combination of mineral fertilizers increased accumulation of N, P, K, Ca and Mg in grain, while urea was more favourable for Fe and Zn increase. Experimental results indicate that proper combination of mineral, organic and microbiological fertilizers could have positive effects on maize yield, as well as quality of maize grains produced in monoculture, irrespective to its negative aspects.
