Résumé
Background: Cassava processing wastes usually generated from edible roots of Manihot esculenta Crantz may cause environmental problems when abandoned in the surroundings of processing plants or carelessly disposed. This study was conducted to assess the response of Zea may L. to cassava wastes affected soil in the study area.
Methods: Viable seeds of Z. mays were sterilized and sown in polybags containing 2.0kg of sandy loam soil obtained from cassava processing site, alongside a control (normal soil) treatment containing 2.0kg sandy loam soil obtained from an area of about 1km away from the cassava mill processing site. Plant growth parameters such as plant height, leaf number and root length were examined.
Results: The plant height, leaf number and root length of Z. mays grown in cassava processing wastes affected soil were comparatively lower (P < 0.05) than that of the control treatment. The pH value of cassava processing wastes affected soil was 4.23, while that of the control treatment was 5.20. The calcium, potassium, sodium, and magnesium contents of Zea mays grown in cassava processing wastes affected soil were significantly (P <0.05) lower than that of the control treatment. The organic matter, the total nitrogen, potassium, sodium and magnesium contents of cassava processing wastes affected soil were significantly (P <0.05) lower than that of the control treatment.
Conclusion: This study showed that the growth and development parameters of Zea mays were negatively affected by cassava processing wastes affected soil.
