The sustainable development of crop production is one of today's most important agronomic challenges. Modern technologies such as precision farming, including nutrient management and irrigation strategies, play a key role in optimising yields and ensuring sustainability. In an experiment set up at the DE AKIT DTTI Látókép Crop Production Experiment Site, we investigated the phenometric (leaf area index, development dynamics), physiological (relative chlorophyll content, NDVI value, water release dynamics) and yield parameters (yield, individual ear and kernel weight, individual kernel number, thousand kernel weight, protein, oil, starch and grain moisture content). Based on the evaluation of yield, it was found that the highest yield (20.95 t/ha) was obtained by the mid-ripening FAO 390 hybrid, significantly higher than the yield of the other examined hybrids. Altogether, it was found that there were significant, in many cases statistically significant, differences in the phenometric, physiological and yield parameters studied between maize hybrids of different maturity, allowing for a precise differentiation of the main traits of each hybrid.
