Conteúdo:	The quality of planting material plays a key role in the sustainability and profitability of cassava cultivation. This study evaluated how different planting materials and supplemental irrigation affect cassava growth, yield, and the quality of harvested cuttings. The experiment took place at the State University of Southwest Bahia, in Vitória da Conquista from March 2024 to March 2025. We used a randomized block design in a split-plot arrangement with three replications. Irrigation (with and without) was the main plot treatment, and the subplot treatment was the type of planting material (conventional cuttings, micropropagated plantlets, and mini-cuttings derived from etiolated plantlets). Irrigation increased plant height by 37% and tuberous root yield by 70%. The type of planting material had no significant effect on root yield, but it did influence stems characteristics and cutting quality. Under irrigation, plantlets and mini-cuttings produced plants with thicker stems, whereas conventional cuttings produced more stems. Irrigated cuttings had more buds but lower dry matter content. Plants grown from plantlets and mini-cuttings had greater weight and diameter compared to those from conventional cuttings. In conclusion, irrigation increased cassava root yield, and modern planting materials such as plantlets and mini-cuttings improve the quality of cuttings for future propagation.
