Optimizing nitrogen use in rapeseed systems: A global meta-analysis of yield gains and environmental trade-offs

Rapeseed (Brassica napus L.) is often grown under high nitrogen (N) fertilization, increasing the risk of N losses and associated environmental impacts. Using a systematic literature search of Web of Science and Google Scholar (1995-2024) and predefined inclusion criteria, we synthesized 106 field s...
