Other claims from this paper (8)
- Intervention effect Joint N+Mg fertilization gave higher maize grain yield, nitrogen uptake and nitrogen utilization than N alone.
- Intervention effect Joint N+Mg fertilization increased the efficiency of applied nitrogen compared with N alone.
- Intervention effect The SG hybrid ES Paroli had significantly greater nitrogen uptake with grain yield and nitrogen utilization than ES Palazzo.
- Association Increasing nitrogen fertilization significantly reduced utilization of nitrogen from the mineral fertilizer dose.
- Intervention effect Magnesium oxide at 25 kg MgO·ha -1 significantly increased mineral N-NH4 in the 0-30 cm and 30-60 cm soil horizons compared with 0 kg.
- Intervention effect Magnesium oxide at 25 kg MgO·ha -1 reduced soil N-NO3 in both horizons compared with 0 kg.
- Association Increasing nitrogen dose significantly increased NH4NO3 mineral nitrogen in soil after maize harvest.
- Intervention effect The SG hybrid ES Paroli caused lower soil eutrophication than ES Palazzo in the autumn period.
