Przydatność pszenżyta ozimego w różnych warunkach gospodarowania w świetle wymogów integrowanej ochrony oraz Europejskiego Zielonego Ładu

The introduction of the European Green Deal by the European Commission poses new challenges in breeding work on varieties that will demonstrate natural resistance or tolerance to diseases and abiotic factors. Based on the results of research conducted by the Central Research Centre for Cultivar Testing, obtained within the framework of Post-registration Variety Testing and Ecological Variety Testing, an assessment was made of the impact of limiting the use of plant protection products and mineral fertilization on the resistance of the Belcanto variety to selected pathogens, yield and selected morphological features. The suitability of the variety for cultivation in a system limiting the use of pesticides and mineral fertilization was also assessed. Giving up fungicide protection and nitrogen fertilization led to a decrease in yield and 1000-grain weight and reduced the height of the plants. The Belcanto variety showed the greatest resistance to powdery mildew and a higher 1000-grain weight in 3 out of 5 growing seasons in the organic cultivation system.
