e0“In 1993, corn following soybean, compared with corn under high chemical management, had greater DM and N accumulation during vegetative development but similar N accumulation after silking (45 kg ha −1 ) and yield (7.6 and 7.2 Mg ha −1 , respectively).”

- Intervention effect In 1993, corn after soybean had greater vegetative dry matter accumulation than corn under high chemical management.
- Intervention effect In 1993, corn after soybean had greater vegetative nitrogen accumulation.
- Intervention effect In 1993, yield was similar at 7.6 and 7.2 Mg ha −1.
- Intervention effect In 1994, vegetative dry matter and nitrogen accumulation were similar for corn after soybean and high chemical management.
- Intervention effect In 1994, post-silking nitrogen accumulation was greater after soybean, 59 versus 35 kg ha −1.
- Intervention effect In 1994, yield was greater after soybean, 11.4 versus 10.7 Mg ha −1.
- Intervention effect In 1994, wheat/clover rotation increased vegetative dry matter and nitrogen accumulation relative to corn after corn under high management.
- Intervention effect Wheat/clover rotation under high chemical management had the greatest post-silking nitrogen accumulation, 79 kg ha −1.
- Intervention effect Wheat/clover rotation under high chemical management had the greatest yield, 12.0 Mg ha −1.
- Association Corn yield rose linearly with post-silking nitrogen accumulation in both years.
- Mechanism The authors conclude post-silking nitrogen accumulation influenced rotation yield response more than vegetative accumulation.
