Collaborative project: Sustainable winter oilseed rape production through breeding improvement of the NUE and optimization of the cultivation system - subproject C (NaWiRa)
Project
Project code: 281D107C21
Contract period: 15.08.2023
- 14.08.2026
Budget: 105,760 Euro
Purpose of research: Applied research
Keywords: crop production, fertilization, resource protection, resource efficiency, crop production, cultivation, rape seed
The aim of the project is to develop optimized cultivation methods based on genomically selected, more nitrogen-efficient winter oilseed rape hybrids in a multi-stage approach, which realize higher and stable oilseed rape yields and lower N-balance surpluses with significantly lower nitrogen supply. The project pursues the hypotheses that both the individual factors i) genotype, ii) fertilizer form and iii) sowing technique, but especially a coordinated combination of the factors mentioned, can influence the reduction of N-balance surpluses at the same or even higher yield. Therefore, the NaWiRa project will identify more nutrient-efficient winter oilseed rape hybrids and investigate the interaction between hybrids, nitrogen fertilization, and optimized stand distribution through even-rate seeding. The analysis of these multi-layered interactions will provide answers to the question of how genomic selection, nitrogen fertilizer application and seeding technology should be coordinated to achieve the best possible use of nitrogen fertilizer and thereby improve the sustainability of winter oilseed rape cultivation. This is intended to be the starting point for new, future-oriented cultivation systems in winter oilseed rape. Based on the knowledge gained here for the optimization of genotype-fertilization-sowing technique interactions, the way is to be paved for e.g. GPS-controlled mechanical weed control and, in addition, the development towards spot farming is to be advanced. In the future, the latter will allow plant-specific, robot-controlled fertilizer application through geo-referenced positioning of the plants.
