Traditional pattern of cashew cultivation: A lesson from Sumenep-Madura, Indonesia

Belonging to the Anacardiaceae family, the cashew tree (Anacardium Occidentale, Linn.) is one of the important tropical plants that possess high economic value. This plant is commonly grown in Indonesian regions including Sumenep, Madura, where the red sandy loam type of soil is commonly present. This study aims to obtain rough data on the pattern of cashew cultivation and identify the cashew cultivation knowledge of local communities. Data were taken in Bringin village, Sumenep-Madura. Our field survey showed that the cashew's cultivation pattern in this village applies the so-called traditional organic farming. Cashew trees are planted along the boundaries of the owner's farm field, functioning as a fence of their farm. Nevertheless, our survey also indicated that this pattern of cultivation is still below standard of cultivation. The planting distance between the cashew trees with one another is relatively close (< 5 meters), causing the cashew branches to overlap with each other. Moreover, we observed that there was no rejuvenation of old cashew trees. Finally, knowledge of the community about post-harvest processing is limited. Therefore, we suggest that educating the community about good standard cashew cultivation is required to improve productivity as well as the quality of cashew nuts.
