The long-term experiments carried out by the University of Debrecen provided an extensive database in relation to the local impacts of climate change in the case of the most important crops produced in Hungary during the last decades. It was concluded that there was 580 mm precipitation shortage in the last 25 years. The long-term experiment results showed that climate change has an impact on the selection of genotype, the nutrient supply of field crops, as well as their population density and other agrotechnical factors. The performed long-term experiments showed a close interactive effect on the water and nutrient supply of field crops. Based on the performed cumulative yield analysis, it was concluded that the yield drop of the control treatment of winter wheat was 53.8 t ha-1 between 1986–2015. The unfavourable impacts of climate change can be partially counterbalanced by the available water of soil, as shown by the water stock dynamics analyses of the soil. The unfavourable impacts of climate change can be successfully mitigated by technologies adapted to production site and variety.
