Other claims from this paper (11)
- Intervention effect Ridge tillage increased soil profile water at emergence and mid silk on Estelline soil in 1988 and 1989.
- Association Mid silk soil moisture correlated significantly with earleaf N, total N uptake, and grain yield in 1988 and earleaf N and grain yield in 1989; correlations were stronger in 1988.
- Observation Estelline corn grain yield showed a tillage by nitrogen rate interaction in 1988.
- Intervention effect Within ridge tillage, maximum yield was reached at 130 kg ha−1 nitrogen.
- Observation On Estelline soil in 1989, yield responded to tillage and nitrogen rate without an interaction.
- Observation Averaged over nitrogen rates, ridge, moldboard, and chisel yields were 7.1, 6.6, and 6.5 Mg ha−1, respectively.
- Intervention effect Ridge tillage increased total plant nitrogen uptake over moldboard or chisel tillage in 1988.
- Observation In 1989 nitrogen uptake was affected by nitrogen rate alone.
- Intervention effect On Egan soil, tillage did not affect soil moisture, nitrogen uptake, or grain yield in either year.
- Intervention effect Corn grain yield increased with nitrogen rate up to 195 kg ha−1.
- Recommendation Ridge tillage may improve soil water holding capacity, nitrogen utilization, and corn yield on some soil types.
