ABSTRACT
The analysis for the bioconcentration studies of cassava leaf infected with mosaic diseases was carried out using standard analytical methods. The result of the analysis for infected sample were: Moisture 7.90%, Ash 8.00%, Carbohydrate 97.00%, Protein, 2.97%, Nitrogen 0.49%, Calcium 86.40mg/kg, Magnesium 28.80mg/kg, Sodium 0.02 mg/kg, potassium 0.18 mg/kg, Phosphorus 0.83 mg/kg and non – affected had: 24.78%, 3.00%, 98.25% and 0.28%, for Moisture, Ash, Carbohydrate and Nitrogen respectively. Calcium, Magnesium, Sodium, Potassium and Phosphorus recorded 105.60mg/kg, 33.60mg/kg, 0.02 mg/kg, 0.16mg/kg and 0.40 mg/kg. The result reveals that the sample accumulated all the analyzed parameters, but there’s need to treat cassava affected with mosaic virus.
