Other claims from this paper (15)
- Observation Hairy vetch produced 5 ton/ha above-ground dry matter at planting.
- Observation Hairy vetch produced a nitrogen yield of 200 kgN/ha at planting.
- Association Under winter fallow, corn nitrogen status and yield decreased as fertilizer nitrogen was reduced.
- Association Under hairy vetch manure, corn nitrogen status and yield did not differ across fertilizer rates.
- Observation Corn total dry matter with vetch and no fertilizer was 22 ton/ha in 1997.
- Observation Corn total dry matter with vetch and no fertilizer was 20 ton/ha in 1998.
- Intervention effect Vetch manure raised corn dry matter by 9 ton/ha over fallow without fertilizer in 1997.
- Intervention effect Vetch manure raised corn dry matter by 13 ton/ha over fallow without fertilizer in 1998.
- Intervention effect Corn nitrogen uptake with vetch and no fertilizer was slightly lower than with vetch and fertilizer.
- Intervention effect Vetch increased corn nitrogen absorption over fallow by 141 kgN/ha without fertilizer in 1997.
- Intervention effect Vetch increased corn nitrogen absorption over fallow by 159 kgN/ha without fertilizer in 1998.
- Observation Vetch reduced corn nitrogen fertilizer requirement by 149 kgN/ha in 1997.
- Observation Vetch reduced corn nitrogen fertilizer requirement by 161kgN/ha in 1998.
- Intervention effect Corn absorbed more soil nitrogen at 60kgN/ha with vetch than at 180 or 240 kgN/ha under fallow.
- Recommendation Winter cultivation and incorporation of hairy vetch could reduce fertilizer nitrogen for corn.
