Other claims from this paper (9)
- Association Growth stage and growing degree days were strongly correlated in rye and triticale cover crops.
- Association The C/N ratios of the cover crops increased with increasing GDD, DAP and growth stage.
- Observation The C/N ratios were similar for rye and triticale.
- Observation The C/N ratios became more variable over time.
- Observation Shoot biomass of October-planted cover crops reached a C/N ratio of 20 at Feekes 10.1 (heading), 97-103 days after planting.
- Observation Shoot biomass of November-planted cover crops reached a C/N ratio of 20 at Feekes 8 (flag leaf just visible), 94-98 days after planting.
- Observation Fitted regression curves showed a C/N of 20 occurring by 94 to 102 days after planting for October and November plantings, respectively.
- Observation Accumulated GDD to reach a C/N of 20 varied with planting date, ranging from approximately 650 to 900 GDD.
- Intervention effect Accumulated GDD to reach a C/N of 20 tended to decrease with later plantings.
