3-year field study assessing DMPP and fertilizer application timing effects on N2O. Under semiarid Mediterranean conditions rainfall variability is the key driver. Due to the scarce rainfall, DMPP is effective for N2O mitigation. Single fertilizer application at tillering reduced N2O but also crop yields
