Climate change poses a new challenge for maize producers which calls for the re-thinking of each production technological element. Professional nutrient replenishment may represent an alternative for the mitigation of yield decrease caused by climate change by means of improving yield stability from the aspect of global food safety, as well as increasing yield and improving yield quality. In the course of a six-year (2011-2016) research, under changing climatic conditions we studied how different fertilization methods - 11 different N doses (0-300 kg ha-1) - affect the productivity of maize and protein content of grains.The experiment was carried out in Hungary (47o 33’ N, 21o 26’ E, asl: 111 m) in the long-term experiment of the University of Debrecen.
