Cowpea [Vigna unguiculata (L.) Walp.] plays an important role in the livelihoods of the people of sub-Saharan Africa, but phosphorus (P) deficiency in soils is a serious problem that contributes to low productivity. This study was conducted to verify the efficiency of indigenous rock phosphate (R...
