The proximate and mineral composition of cocoyam (colocasiaescienta) grown in Bauchi, Plateau, Gombe and Kaduna States were analyzed using association of official analytical chemistry. The analysis included, ash; 3%, 2.6% and 3.2% crude protein; 2.7%, 3.4%, 2.8% and 2.9% crude fibre; 1.5%, 1.9%, 1.8% and 1.0% crude fat; 0.3%, 0.3%, 0.2% and 0.4%. Moisture; 19%, 21%, 15.3% and 16.5%. Carbohydrate; 73.5%, 70.5%, 77.3% and 75.6% for the results obtained from Bauchi, Plateau, Gombe and Kaduna States. The mineral contents were determined using Atomic Absorption spectrophotometer (ADS), were as follows; P. 51423 PPM, 803.11PPM, 550.71PPM and 445.45PPM. Zn: 7.53PPm, 14.01PPM, 10.25PPM, 7.4PPM. Ca: 896.1PPM, 1110.39PPM, 864.98PPM and 884.87PPM. Fe: 48.91PPM, 3.21PPM, 50.88PPM and 31.67PPM. Cu: 6.58PPM, 11.09PPM, 4.86PPM and 5.9PPM. K: 3478.71PPM, 4630.20PPM, 3617.91PPM and 3236.63PPM. Mg: 334.11PPM, 506.73PPM, 367.73PPM and 324.71PPM. Mn: 5.11PPM, 8.43PPM, 6.30PPM and 4.80PPM. Na: 204.89PPM, 203.59PPM, 159.34PPM and 191.12PPM for the results of samples obtained from Bauchi, Plateau, Gombe and Kaduna States, the high level of carbohydrate observed from all the samples also agrees with the finding reported by FOA (1990), that the main nutrients supplied is dietary energy provided by the carbohydrates. The results from the current study reveal that cocoyam is nutritionally rich in carbohydrate and minerals such as potassium and sodium.
