Other claims from this paper (12)
- Intervention effect Stocking rate markedly affected Siratro seed set and seedling demography.
- Intervention effect At the highest stocking rate, Siratro yields were low.
- Intervention effect At the highest stocking rate, seed input ceased after 1972.
- Intervention effect Seedling recruitment from the soil seed bank was appreciable and maintained for a further 10 years at the highest stocking rate.
- Intervention effect Seed set and soil seed reserves were highest at the lightest stocking rate.
- Intervention effect Seedling recruitment was of little importance at the lightest stocking rate.
- Intervention effect Seedling recruitment and survival were best at the intermediate stocking rate.
- Mechanism Seedling recruitment and survival were the key to long-term persistence of Siratro.
- Observation Soil seed reserves of Siratro were about 500 m-2 under light stocking.
- Observation Soil seed reserves of Siratro were below 100 m-2 after several years of heavy stocking.
- Observation Very little Siratro seed was recovered in cattle faeces.
- Recommendation Studies of this type can help in qualitatively predicting long-term persistence of pasture legumes.
