Other claims from this paper (13)
- Intervention effect Sulfur application significantly increased maize yield and yield components versus control.
- Intervention effect At 60 kg ha−1 sulfur, maize fresh matter increased by 41%.
- Intervention effect At 60 kg ha−1 sulfur, maize dry matter increased by 55%.
- Intervention effect At 60 kg ha−1 sulfur, maize stover increased by 58%.
- Intervention effect At 60 kg ha−1 sulfur, maize 1000‐grain increased by 5%.
- Intervention effect At 60 kg ha−1 sulfur, maize total grain increased by 43%%.
- Intervention effect Sulfur fertilization significantly increased soil SO4‐S concentration at silking, reaching 108.4 mg kg−1 with 120 kg S ha−1.
- Intervention effect Sulfur fertilization significantly increased soil SO4‐S concentration at harvest, reaching 99.7 mg kg−1 with 120 kg S ha−1.
- Intervention effect Sulfur application significantly increased maize leaf sulfur concentration versus control.
- Observation At 60 kg ha−1 sulfur, maize leaf sulfur concentration was 0.46%, below the 0.5% critical level.
- Intervention effect Higher sulfur treatments raised maize leaf sulfur concentration to 0.67–0.94%, exceeding high and excessive thresholds.
- Association Elevated tissue sulfate under sulfur treatments above 60 kg ha−1 corresponded to lower maize yield.
- Recommendation The authors advise local maize growers to apply up to 60 kg ha−1 sulfur for maximum yield.
