In this research, excellent maize hybrids grown over a large area in Hungary were tested in a super intensive drip irrigation experiment. The experiment was set up at the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Debrecen Educational Farm and Landscape Research Institute (DE AKIT DTTI) the Látókép Crop Production Experimental Station. In our study, eight hybrids with different FAO numbers were analysed under field conditions in drip irrigation long-term experiments. The yield of each genotype and the yield components determining the yield were estimated on the basis of individual sampling after physiological maturity. After sampling, the average individual grain weight, individual grain number, thousand grain weight and yield of each genotype were determined by individual sample processing. Despite unfavourable agro-meteorological factors, intensive production techniques resulted in yields of genotypes H3, H5 and H6 all exceeding 15 t ha-1, indicating high yield stability of the examined genotypes. Two factors, individual grain number and individual grain weight, are of primary importance in the development of yield. Genotype-specific evaluation of these factors revealed that the genotype H6 was prominent in the values of individual grain number, outperforming the other examined hybrids by about 9–34%. In addition, in the experiment, the H5 hybrid also had an individual grain number exceeding 600 grains per ear, significantly outperforming the other tested hybrids. The genotype H4 proved to be the most outstanding in terms of thousand grain weight with a value of 465.71 g. These results showed that the hybrid had 10–27% higher thousand grain weight compared to the other tested genotypes. Of the examined hybrids, H2 and H3, which exceeded 400 g thousand grain weight, showed outstanding values despite the fact that they are short maturity hybrids.
