- •
N2O emissions from plastic mulching maize were evaluated under different N splits.
- •
Fertilization combined with rainfall was the main driving factor for N2O emissions.
- •
Applying N with three splits had a high risk for increasing N2O emissions.
- •
N two splits could produce higher grain yields, and lower risk of N2O emissions.
