Other claims from this paper (13)
- Observation irrigated Caucasian clover produced 11.9 t DM/ ha.
- Observation dryland conditions Caucasian clover produced 9.4 t DM/ha.
- Observation Caucasian clover outyielded white clover by about 2.5 t DM/ha under both irrigation treatments.
- Association Irrigated Caucasian production rates rose 11 kg DM/ ha/day/oC as temperature increased from 8-16 oC.
- Association Irrigated white clover production rates rose 8 kg DM/ha/ day/oC as temperature increased from 8-16 oC.
- Association Caucasian clover production rates fell more than white clover in late summer and autumn as temperatures dropped.
- Observation Caucasian clover leaf photosynthesis exceeded white clover by about 6 ƒÊmol CO2/m2/ s across measured temperatures and moisture.
- Observation Both clovers had similar optimum temperature ranges of 21-25 oC for photosynthesis.
- Observation Both clovers had similar soil moisture ranges of 1.00-0.86 of WHC for photosynthesis.
- Observation Caucasian and white clover had similar phyllochron of 126 oCd.
- Observation Caucasian clover had base temperature of 5 oC versus 1 oC for white clover.
- Mechanism The authors attribute lower autumn Caucasian clover production partly to slower canopy recovery after grazing.
- Recommendation The authors suggest Caucasian clover could increase spring and summer legume production in New Zealand pastures.
