e0“In 1986, conventional tillage resulted in greater yield than with no‐till, but the reverse was true in 2002”
e1“The objective of this 20‐year study was to determine the response of grain sorghum [ Sorghum bicolor (L.) Moench] and soybean [ Glycine max (L.) Merr.] in rotation to tillage and N fertilization on a claypan soil in southeastern Kansas.”

Other claims from this paper (9)
- Intervention effect Sorghum yield averaged 22% lower under no till than under conventional or reduced tillage.
- Intervention effect Nitrogen fertilization increased sorghum yield.
- Intervention effect Nitrogen fertilization increased kernels per head.
- Intervention effect Anhydrous ammonia yielded 12% more than surface applied nitrogen.
- Association Tillage and nitrogen fertilizer interacted on yield in half of crop years.
- Intervention effect Soybean yield was little affected by tillage, residual nitrogen, or their interaction.
- Intervention effect Conventional tillage produced greater soybean yield than no till in 1986.
- Observation Soybean yields did not differ among tillage systems in the other eight years.
- Recommendation Subsurface anhydrous ammonia may partly ameliorate the sorghum yield penalty under no till.
