Other claims from this paper (8)
- Intervention effect Crop residue returning significantly increased wheat yield by 8.29% versus no returning.
- Association Residue returning benefited wheat yield more in Northwest China and specified climate, soil and rotation settings.
- Intervention effect Residue rates of 3 to 6 t ha −1 gave greater yield benefits than other rates.
- Intervention effect Chopped straw gave greater wheat yield benefits than intact straw.
- Intervention effect Rainfed conditions gave greater wheat yield benefits than irrigated conditions.
- Intervention effect Nitrogen application at 200 to 300 kg ha −1 gave greater wheat yield benefits than other rates.
- Intervention effect Mulch return increased wheat yield by 12.56%, versus 4.53% with plowing residues into soil.
- Association Spring wheat had an 11.90% yield increase versus 7.09% for winter wheat under residue return.
