- Intervention effect Nitrogen alone increased 2016 sorghum yield by 71 bu/a.
- Intervention effect Nitrogen and phosphorus together increased 2016 sorghum yield by up to 93 bu/a.
- Intervention effect Across the previous 10 years, nitrogen and phosphorus fertilization increased sorghum yield by up to 77 bu/a.
- Intervention effect At 80 lb/a nitrogen with phosphorus, sorghum produced 89% of maximum yield in 2016.
- Intervention effect Potassium application had no effect on sorghum yield throughout the study.
- Observation Average grain nitrogen content reached a maximum of about 0.7 lb/bu.
- Observation Average grain phosphorus content reached a maximum of 0.15 lb/bu.
- Observation Average grain potassium content reached a maximum of 0.19 lb/bu.
- Observation At the highest nitrogen, phosphorus and potassium rates, apparent fertilizer nitrogen recovery in grain was 33%.
- Observation At the highest nutrient rates, apparent fertilizer potassium recovery in grain was 40%.
