The overall objectve of this 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 source of protein, with a significantly improved CO2 footprint. To this end, NORA brings together innovations for high-throughput imaging phenotyping of rapeseed crops, genomic selection methods and the latest statistical methods. Based on UAV-based multispectral images, the behaviour of individual hybrid varieties will be described during vegetation. This makes it possible to go beyond the usual static phenotyping to identify dynamic characteristics (e.g. N concentration in biomass growth over the course of vegetation) that are relevant for high N efficiency and have a particularly favourable effect on GHG emissions. Finally, these are to be linked to genomic information of the respective rapeseed genotypes in order to identify decisive genetic determinants and improve prediction models to select N-efficient varieties more quickly. In addition, the data obtained will be used to develop adapted recommendations for N fertiliser management for rape farmers. Translated with DeepL.com (free version)
