Megjegyzések:	Nitrogen and water are among the most important maize (Zea mays L) crop inputs for optimum production. A pot experiment was conducted in the under the green house garden in the 2019 cropping season in the University of Debrecen, Hungary to evaluate the impact of Nitrogen and water stress on the vegetative growth of different maize genotypes. Three nitrogen doses or rates (0, 120kg and 240kg) were applied, where 0 kg rate of nitrogen was the control experiment. The results revealed that nitrogen and enough water supply treatments significantly affected the growth and development of the maize crop at the vegetative stage. Photosynthetic parameter of SPAD was significantly affected at 240kg rate in all the four genotypes used in the experiment. NDVI was significantly affected in the genotype Behilifa (GH) between the doses with the maximum value at 240kg is 0.88. The leaf area index and plant height were significantly affected at the 240kg rate of nitrogen by the three of the genotypes used (DKC, P9903 and Behilifa). Fresh biomass weight was significantly affected in all the genotypes at 240kg rate nitrogen application. The efficient use of nitrogen in this experiment was achieved at 240kg rate with enough supply of water at 60% field capacity in all the cultivars used for this experiment.
