Other claims from this paper (14)
- Method / resource Logistic equations fit the height and diameter growth responses.
- Observation Polybag seedling height grew rapidly June to November, accounting for 83.99% of annual height growth.
- Observation Field-sown seedling height grew rapidly May to November, accounting for 86.65% of annual height growth.
- Observation Polybag stem diameter grew rapidly June to November, accounting for 86.71% of total stem growth.
- Observation Field-sown stem diameter grew rapidly May to November, accounting for 84.60% of total stem growth.
- Observation Both cultivation types developed nine extension units annually and one monthly from May through November.
- Observation Extension unit formation did not stop during the year, whereas height growth rate differed seasonally.
- Observation Field-sown seedlings had earlier leaf phenophase than polybag seedlings.
- Observation Field-sown seedlings had larger extension units than polybag seedlings.
- Association Precipitation had the greatest impact on seedling growth across cultivation systems.
- Observation Height and diameter grew throughout the year and fastest in the rainy season.
- Observation Height and diameter showed isogony under both cultivation systems.
- Observation Extension units and leaf phenophase were consistent and synchronized across cultivation systems.
- Recommendation Management should be tailored to rubber seedling cultivation type.
