This study aims to examine the effects of biological fertilizer consists of microorganisms, which bind the free nitrogen (N2) of air in an asymbiotic way, like Azospirillum sp., Azorhizobium sp. and Azoarcus sp. on the properties of soil and nutrient contents of the plant and some agronomic properties of corn. The experiment was set up in a randomized block design with 3 repetitions. In the experiment, 2 doses of biological fertilizer (0–0,5 g ha-1; BF0-BF1) and 3 doses of nitrogen fertilizer (0 – 125 – 250 kg N ha-1;N0- N1- N2) were applied. Consequently, the effects of the applications on the electrical conductivity of soil, NO3-N were statistically significant, and in the second period, the effects on available Mn in the soil, and iron and copper in the plant, and agronomic properties like cob diameter, height of the first cob, stem thickness were determined. The biological fertilizer enabled the corn plant to make better use of the Fe element in the soil.Compared to the control parcel (BG0N0), an increase of 22,3 g cob-1 (24,03%) in grain weight and 183 kg da-1 (24,04%) in grain yield was detected with biological fertilizer application (BG1N0). These results Show the effectiveness of biological fertilizer. It was concluded that for environmentally friendly and economical corn production 125 kg N ha-1 nitrogen may be recommended along with a 0,5 kg ha-1 biological fertilizer.
