- Association In the driest year, sorghum yielded 137% more than corn under conventional tillage.
- Association In the driest year, sorghum yielded 85% more than corn under no-till.
- Association In 3 of 5 years, no-till corn yielded 34% to 112% more than no-till sorghum.
- Association In the remaining year, conventional-till sorghum yielded more than conventional-till corn.
- Association In the remaining year, no-till yields of corn and sorghum did not differ.
- Intervention effect Overall, no-till increased corn yield by 28%.
- Intervention effect Overall, no-till increased corn net return by 69%.
- Intervention effect Overall, no-till had no effect on sorghum net return.
- Association No-till corn yielded 28% more than no-till sorghum.
- Association No-till corn produced 169% more net return than no-till sorghum.
- Association Conventional-till corn yielded 11% more than conventional-till sorghum.
- Association Conventional-till corn produced 48% more net return than conventional-till sorghum.
- Recommendation Dryland corn can be grown in western Kansas if lower yields and returns are accepted in dry years.
- Association Corn yields and returns are considerably higher than sorghum in favorable years.
- Intervention effect No tillage will substantially increase corn yields in most years.
- Recommendation No tillage is essential for adequate corn yields in dry years.
