Other claims from this paper (5)
- Intervention effect Following hairy vetch, maximum corn grain yield exceeded that following rye by 0.6 Mg ha −1 with 45 kg ha −1 starter nitrogen.
- Intervention effect At one site with hairy vetch biomass above 2 Mg ha −1, corn grain yield rose beyond the contribution of legume nitrogen alone.
- Intervention effect Optimum sidedress nitrogen rates with hairy vetch were similar to other winter cover crops.
- Intervention effect Hairy vetch generally produced higher soil nitrogen than other cover crops at corn V4.
- Intervention effect Soil nitrogen did not differ among cover crops after corn harvest.
