Megjegyzések:	Three maize hybrids of different genotypes (Merida; Armagnac; Fornad) were involved to study the effects of basal fertilization, top-dressing and irrigation on the values of different vegetation indexes (NDVI and UAV NDVI) and yield in 2021. The studies were conducted at the Látókép Experimental Station of the University of Debrecen in Hungary. The experiment is two-replicate, one and a half hectare, two-plot, set up in 2011. In the field trial, nitrogen (N) fertilizer rates were applied as basal fertilization and top-dressing in addition to the nonfertilizer (control, A0) treatment. The 60 and 120 kg N ha-1 applied as spring basal fertilizer was followed by two top-dressings at V6 and V12 phenophases at rates of +30 and +30 kg N ha-1. When examining the effect of fertilizer treatments, averaged over irrigation and hybrids, the lowest NDVI value was measured in the A0 treatment (0.685?0.148), while the highest NDVI value was obtained in the A120 treatment (0.734?0.133). Averaged over irrigation and fertilizer treatments, the highest NDVI value among hybrids was obtained for the Fornad hybrid (0.718?0.145), which was statistically confirmed. A significantly lower NDVI value was measured for the hybrid Merida (0.703?0.149). The NDVI value of the hybrid Armagnac was not statistically different from the other two hybrids. Irrigation had a statistically significant effect on NDVI (+0.014). Linear regression analysis of treatments and irrigation showed that irrigation increased NDVI values in all cases except in treatments V12120 and V12180. Based on the tests, the correlation between NDVI and UAV NDVI values was moderately strong (r=0.72; R2=0.517) for the average of -fertilizer treatments and hybrids. The highest yield (12.03?1.09 t ha-1) was statistically provided by the A120 treatment in the average of hybrids and irrigation. It can be concluded that the NDVI values give a reliable overview of yield trends.
