The tapade gardens of Fouta Djallon have been highly researched by international scholars from various disciplines. This research has revealed that the cuntuuje system has a higher soil nutrient level than any other soil in the region. Almost all labor, except for the initial preparation, is performed and managed by women and children, in the past and now, within each family group. The gardens are important for both food and cash crops for their families. PLEC, a project of the United Nations University, measured yields on 6.5 ha from tapade fields at Misiide Heyre, Fouta Djallon and found that maize yielded up to 7 t/ha, cassava 21 t/ha, sweet potatoes 19 t/ha, and groundnuts (peanuts) about 8 t/ha.
