The concentrations of some minerals (K, Ca, P, Mg, Mn and Cu) found in garlic species grown in Nigeria, Senegal and Chad were determined using Atomic Absorption Spectroscopy. The results showed that Nigerian garlic specie contained the highest concentration of phosphorus (1.29 mg/L) and Copper (0.017 mg/L). Calcium was found to be highest in Senegalese garlic specie (8.639 mg/L) with the Nigerian specie having the second-highest recorded value (6.930 mg/L). The highest values of potassium, magnesium and manganese content were recorded for Chadian garlic (68.26 mg/L), (51.60 mg/L) and (0.212 mg/L), respectively. Also from the results, there is notable variation in the concentration of the minerals, and this may be attributed to the types of soils on which the different garlic species were grown.
