Application of organic agroindustrial residues on agriculture can be one way to improve the development and chemical composition of plants, reducing the cost with chemical fertilizers and impacts generated by the excessive use of them. Sugarcane agroindustrial residue has been generated in high quantity in Brazilian semiarid region and can be applied to cassava crop to improve its growth. The aim of this work was to evaluate the effect of application of sugarcane agroindustrial residue on the vegetative development, chemical composition and mycorrhizal association of cassava plants (Manihot esculenta var. Engana ladrão). It was performed an experiment in greenhouse with completely randomized design with four treatments of addition of sugarcane agroindustrial residue (0, 5, 10 and 15%) with nine replicates. The addition of sugarcane agroindustrial residue increased fresh dry root biomass, leaf area, crude protein and mineral matter, without reducing the mycorrhizal colonization and glomerospores number. This type of residue can be one alternative to improve the nutritional value of these fodder.
