Myrciaria Dubia - Harvest

Harvest

Long used by native peoples, wild Camu camu fruit is harvested directly into canoes. The fruit has only recently come into large-scale cultivation and sale to the world market with Japan being the major buyer. It is relatively easy to cultivate. It survives best in hot, damp tropical climates but will grow in the subtropics, surviving temperatures down to just above freezing. It requires copious water. Fair trade is present in low-land production from the Association of Camu Camu Producers of the Peruvian Amazon.

The tree occurs in locally dense populations (1000/ha) or even monospecific stands in Amazonian flood plains and riparian vegetation. The plant is extremely tolerant of flooding, withstanding 4 to 5 months with the roots and even much of the aerial parts submerged in water. The species propagates through seeds. In cultivation, the tree begins bearing fruits after attaining 2 cm in stem girth (three years after emergence of the seedling). Plants flower at the end of the dry season and fruit at the peak of the rainy season. Observations with both wild and cultivated plants suggest that trees can remain productive for several decades.

Wild trees have been found to yield 12 kg of fruit on average. At suggested planting densities of 600–1100 trees/ha, about 12 t fruit can be derived in cultivation from one hectare. However, with improved horticultural techniques, such as the use of clonal elite material, pruning and fertilization, much higher yields could be achieved.
