Oil palm can reach heights of 20–30 m (65.6–98.4 ft) and has an economic lifespan of 25–30 years, at which point they become too tall to be managed efficiently and are cut down. B - High offshoots on the palm using plastic bags fi 8- week old stage corresponded to that found in the zygotic seedling. the plant must have a well developed root system. The architecture of the oil palm, lacking axillary shoots, does not allow for vegetative propagation.
