The study investigated the potentials of organic chelates used in enhancing micro nutrients in cassava to improve the availability of Vitamin C which is a nutrient absorption promoter. The study used EDTA as standard chelate, Bontera as a commercial organic chelate and periwinkle effluents and Smoke Solution (SS) as local organic chelates. The cultivars used were TME419 and TMS3168/UMUCASS/36 also known as YELLOW ROOT (YR). One hundred (100ml) of 100µg of zinc obtained from zinc oxide and 100µg of iodine obtained from potassium iodide were added separately and combined to 5000ml each of deionized water, 1ml/L Bontera, 1ml/L EDTA, Periwinkle effluents and Smoke solution. The treatments were applied through foliar application at 3 months after planting, repeated 3 weeks later and 7 months after planting. The bioavailable Vitamin C in the edible root ranged from 0.18mg/g (EDTA + ZnO; YR; KI + ZnO in TME419) to 0.71mg/g (SS + ZnO + KI in YR). The study revealed that Smoke Solution did better individually (0.67mg/g; TME419) and in combination with other nutrients sources (0.71mg/g; SS + KI + ZnO: YR) in improving Vitamin C availability. The study also revealed that organic chelates have the potential of providing nutrients absorption promoters that will facilitate the absorption of nutrients in which they enhanced the availability in food crops.
