Other claims from this paper (11)
- Observation First-year sorghum yielded 7 Mg ha−1 after legumes.
- Intervention effect In subsequent years nitrogen increased yield by under 20%.
- Intervention effect Low phosphorus rates increased sorghum yield.
- Intervention effect Low potassium rates increased sorghum yield.
- Intervention effect Sorghum yield was greater after birdsfoot trefoil than alfalfa.
- Intervention effect In 1995 under nitrogen, phosphorus increased lodging.
- Intervention effect In 1995 under nitrogen, phosphorus increased stalk rot severity.
- Intervention effect In 1995 under nitrogen, potassium reduced lodging.
- Intervention effect In 1995 under nitrogen, potassium reduced stalk rot severity.
- Intervention effect Potassium fertilization reduced stalk rot severity in 1996.
- Recommendation Sorghum after legume crops required minimal phosphorus and potassium, especially with nitrogen.
