Other claims from this paper (10)
- Association Tillage by year significantly affected sorghum yields.
- Association Nitrogen rate by year significantly affected sorghum yields.
- Observation Each of the three tillage systems yielded more than the others in five to six years.
- Intervention effect Fertilizer significantly increased grain sorghum yields versus control in all but four years.
- Association Fertilizer rate affected grain sorghum yield stability across years.
- Intervention effect Tillage did not affect grain sorghum yield stability across years.
- Intervention effect In low-yielding years, no-tillage above 45 kg N ha−1 had the greatest yield.
- Intervention effect In high-yielding years, tillage had no effect on sorghum yield.
- Intervention effect In high-yielding years, fertilizer nitrogen increased sorghum grain yield.
- Recommendation The authors recommend no-tillage with 45–90 kg N ha−1 to secure yield and stability across years except very low-yielding environments.
