Other claims from this paper (16)
- Observation Environment influenced ADF and lignin levels differently from their deposition rates.
- Observation First regrowth stem ADF averaged 18% higher than second regrowth.
- Observation First regrowth leaf ADF averaged 36% higher than second regrowth.
- Observation First regrowth leaf lignin averaged 67% higher than second regrowth.
- Observation Controlled low-light crownvetch leaf lignin was one-fourth to one-half field levels.
- Association Maturity effects on ADF and lignin were greater at higher-elevation locations.
- Association Late spring 1970 ADF and lignin deposition rates averaged three times those in 1969 and were associated with higher rainfall.
- Observation Leaf cutin was 65% higher than stem cutin.
- Observation Leaf cutin peaked at early or full bloom.
- Observation Stem in vitro digestibility declined 0.81 percentage points daily from flower bud to early bloom.
- Observation Stem digestibility subsequently declined at lower rates.
- Observation First regrowth stem digestibility was 58%, below second regrowth at 66%.
- Observation First regrowth leaf digestibility was 74%, below second regrowth at 78%.
- Association Stem ADF and lignin levels were largely independent of crop yield.
- Association Stem ADF and lignin were inversely related to digestibility.
- Method / resource Nutritive value prediction was more difficult for first-crop crownvetch than for common legumes.
