Megjegyzések:	The small-plot field experiment was set up at the Látókép Field Research Centre of the University of Debrecen, Centre for Agricultural Sciences on a calcareous chernozem soil type. In this experiment the development of yield, leaf area index and relative chlorophyll content of three maize hybrids of different genotypes, namely Sarolta (FAO 290), NK Lucius (FAO 330) and SY Afinity (FAO 470) were studied. Two row spacings (45 and 76 cm) and three plant densities (50, 70 and 90 thousand plants per hectare) were set. Assimilation area of maize hybrids has determining role in yield production; positive correlation can be determined between them. As a result of the application of different row spacings and plant densities yield amount depended on the given crop year. Parallel to the increasing plant density leaf area index increased as well, while relative chlorophyll content decreased. In order to evaluate the studied factors in a complex way, Péter Pepó has introduced the Ph.C. or P-index value that determines the photosynthetic capacity. Strong correlation was found between yield and Ph. C. value in all studied crop years (0.781-0.881**). Photosynthetic capacity values varied between 649 and 1198 in 2013, between 401 and 920 in 2014 while between 206 and 362 in 2015.
