The central concern of the project is to improve the ecological balance of rapeseed cultivation in terms of climate protection by increasing the nitrogen efficiency of winter rapeseed. To this end, direct and indirect CO2 emissions are to be substantially reduced. This makes it possible to produce both rapeseed oil and the so-called rapeseed cake or extraction meal, which serves as an essential domestic protein source, with a significantly improved CO2 footprint. To this end, NORA brings together innovations for high-throughput imaging phenotyping of canola field stands, genomic selection methods and the latest statistical techniques. Based on UAV-based multispectral images, the behavior of individual hybrid varieties will be described in a vegetation-accompanying manner. This will make it possible to go beyond the usual static phenotyping and identify dynamic traits (e.g. N concentration in biomass emergence over the course of vegetation) that are relevant for high N efficiency and have a particularly favorable effect on GHG emissions. Finally, these will be linked to genomic information of the respective canola genotypes to identify crucial genetic determinants and improve prediction models to select more rapidly for N-efficient varieties. In addition, the data obtained will be used to produce adapted recommendations for action on N fertilizer management for rapeseed farmers.
