Megjegyzések:	We have investigated the plant number reactions of six maize hybrids of various genotypes in a field experiment; the plant numbers 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 Centre for Agricultural and Applied Economic Sciences of the University of Debrecen in four replications on chernozem soil. The fertilizer doses applied in favour of the site-specific fertilization were N 108 kg ha-1, P 0 kg ha-1 and K 0 kg ha-1. The hybrids were members of very early (FAO 240-299), early (FAO 300-399) and medium (FAO 400-499) maturation groups. Sarolta was the hybrid of very early, P9578, Reseda, P 37N01 and P 9494 were the ones of the early, while Kenéz was the hybrid of medium maturation. With the increase of the plant number, the yield amounts increased in the case of both applied row distances in the average of the hybrids, but in the case of the row distance of 45 cm, the yield excess was of greater extent. The highest yield increase was resulted by the increase of the plant number from 50,000 to 70,000 plant ha-1 in the case of both applied row distances. In addition to the plant number reaction, we have determined the plant number optimums and intervals of the studied hybrids under the certain growing area and agrotechnical conditions.
