- Intervention effect N applied alone increased sorghum yields by 71 bu/a in 2016.
- Intervention effect N and P applied together increased sorghum yields by up to 93 bu/a in 2016.
- Intervention effect Averaged over 10 years, N and P fertilization increased sorghum yields by up to 77 bu/a.
- Intervention effect Potassium application had no effect on sorghum yield over the study period.
- Observation Average grain N content reached a maximum of about 0.7 lb/bu.
- Observation Grain P content reached a maximum of 0.15 lb/bu.
- Observation Grain K content reached a maximum of 0.19 lb/bu.
- Observation At the highest N, P and K rate, apparent fertilizer recovery in the grain was 33% for N.
- Observation At the highest N, P and K rate, apparent fertilizer recovery in the grain was 69% for P.
- Observation At the highest N, P and K rate, apparent fertilizer recovery in the grain was 40% for K.
- Recommendation N and P fertilizer must be applied to optimize irrigated grain sorghum production in western Kansas.
