Anacardium othonianum

Anacardium othonianum is a woody perennial plant belonging to the Anacardiaceae family, often referred to in Brazil as a regional relative of the commercial cashew. It is a vital crop within the Cerrado biome, where it has been traditionally harvested for its nutritious fruit and nuts.

The origin of this species is central Brazil, where it thrives in a landscape characterized by distinct wet and dry seasons. Its natural distribution is linked to areas with low-nutrient, acidic soils where competition from other plant species is limited, allowing this hardy tree to occupy a significant ecological niche.

Botanically, the plant is characterized by a deep taproot system and thick, leathery leaves that prevent excessive water loss. The tree produces a succulent peduncle (pseudofruit) that is edible and highly valued for its sweet-acidic flavor profile. The botanical nut, containing the seed, is protected by a shell rich in phenolic compounds, which requires careful processing.

Cultivation requirements focus on selecting well-drained, sandy-textured soils. The plant is photophilous, requiring full sun for optimal flowering and fruit set. Agricultural management involves spacing trees to allow for crown development and implementing organic fertilizing practices to maintain soil structure and promote long-term yields.

Typical plant protection issues include fungal diseases like Colletotrichum gloeosporioides (anthracnose), which primarily affects the fruit and leaves during high humidity periods. Pests such as borers and aphids are frequently managed through manual intervention or targeted biological controls to ensure that the ecological integrity of the orchard remains intact.
