The aim of the research is to investigate the effects of salt and drought stress on different maize hybrids. In the course of the research, we measured the photosynthetic activity and different phenological parameters of different maize hybrids in a pot experiment. During the experiment, drought-sensitive and tolerant hybrids were tested under saline and non-saline conditions. The experiment was set up in a foil housing in an environment closed from external precipitation. During the experiment, plant height, leaf area (LAI) and relative chlorophyll content (SPAD) were measured every 2 weeks after a certain phenological state, and total biomass weight, root weight and tube weight were measured on the plants at harvest. In today’s climate-burdened world, we are increasingly confronted with the negative effects of drought and salt stress, but if we can prepare for and counter them, we can simply have a positive impact on our crop results. The experiment sheds light on how much a simple hybrid choice can affect our yield in a drought or normal year, or even on a saline soil. The novelty of the topic lies in the hybrids and field irrigation / water management results can be further refined for hybrids and soil hybrid and soil-specific irrigation adapted can be use.
