Megjegyzések:	The yield and crop safety of maize are influenced by numerous ecological, biological and agrotechnical factors. It is of special importance to study one of the agrotechnical elements, the sowing technology of maize hybrids. We have examined the effects of sowing technology on five maize hybrids of various genotype in a field experiment. The plant densities were 50, 70 and 90 thousand ha-1, while the row distances were 45 and 76 cm. The experiment was set on the Látókép Experimental Farm of the University of Debrecen in 2013. The experiment was set in four replications, on chernozem soil. In the experiment Sarolta, DKC 4014, P 9175, PR 37M81 and P 9494 hybrids were used. According to our experimental results, we have concluded that the increase of the plant density, the yield increased much more at the narrow row spacing. In the average of the hybrids the yield was higher at the 45 cm row spacing and at the plant density was 70 and 90 thousand plant ha-1. In addition to plant density increase, it is necessary to determine the optimal plant density that the most favourable for the certain hybrid under the given conditions. To fulfil this aim, we have determined the optimal plant density corresponding to the maximum yield of the given hybrid, within the given plant density range. The optimal and applied plant densities numbers differ, since the optimal one could only be applied under ideal conditions. Since the agrotechnical actions cannot always be carried out in appropriate quality and one has to adapt to the weather conditions, thus we have determined a plant density range in the case of each hybrid.
