Other claims from this paper (7)
- Intervention effect Pre-sowing N90P60K60 increased winter wheat yield by 2.29 t/ha against no fertilizer.
- Recommendation The authors consider pre-sowing N60P60K60 relevant under optimal weather with later nitrogen fertilization.
- Intervention effect Increasing applied nitrogen to N120-180 did not significantly increase winter wheat yield relative to other variants.
- Intervention effect N120-180 fertilizer sometimes decreased winter wheat yield under drought during grain swelling and formation.
- Intervention effect No pre-sowing fertilizer significantly reduced winter wheat yield against better variants.
- Intervention effect Pre-sowing N16P16K16 significantly reduced winter wheat yield against better variants.
- Intervention effect Pre-sowing N30P60K60 significantly reduced winter wheat yield against better variants.
