Megjegyzések:	The field research was carried out on chernozem soil at the Látókép AGTC KIT research area of the University of Debrecen. In 2012, effects of plant density and fungicides on growth and yield were examined in three different genotypes of hybrid sunflowers (P64LC09, Paraiso 1000 and ES Tectonic). We applied two variations of plant density measures (35 000 plants ha-1 and 55 000 plants ha-1) and two different treatment levels of fungicides (control = no fungicides applied, double fungicide protection).The leaf area index (LAI) ranged between 0.6 AND 5.4 m2/m2 during the research and the highest values of LAI were measured in the beginning of July. In the year of 2012, crop yield varied between 1826 and 3602 kg ha-1. Optimum plant density was 55 000 plants ha-1 in both the cases of control and double protected plants. According to our examination, fungicide treatments enhanced yields. This result is also underpinned by the fact that yields in the control stand were lower than those of the double protected ones. Based on our results we found that plant density significantly determined the amount of yield (r=0.820). Besides, it affected the size of the leaf area as well. Beside plant density, the fungicide treatment also affected the size of the leaf area. The genotype significantly affected the degree of maximum leaf coverage (r=0.412, r=0.418**).
