Rubber tree plantations in Southeastern Côte d'Ivoire were studied to improve rubber yield by investigating the influence of tapping depth. The study found that tapping to a depth between 1 and 1.5 mm from the cambium results in higher yields but poorer tapping quality, while tapping to a depth between 1 and 2 mm gives lower yields but better tapping quality. The tapping depth is affected by the height of the tapping panel and the clone of the rubber tree.
