The use of plastic containers in the production of forest seedlings presents environmental limitations associated with waste generation and the use of petroleum-derived materials. In this context, biodegradable containers produced from agro-industrial residues emerge as a sustainable alternative. This study aimed to evaluate the feasibility of using biodegradable containers made from agro-industrial residues in the production of Magonia pubescens seedlings. The experiment was conducted in a screened nursery (50% shading) at the Center for Agricultural Sciences of the State University of the Tocantina Region of Maranhão (UEMASUL), in Imperatriz, Maranhão, Brazil. Four treatments were evaluated: T1 – plastic container (control); T2 – 100% crushed açaí seed + binder; T3 – 80% crushed açaí seed + 20% clay + binder; and T4 – 100% sawdust powder + binder. The experimental design was completely randomized, with five replicates per treatment. Germination percentage, germination speed index, shoot height, stem diameter, and seedling robustness quotient were evaluated, as well as the structural integrity of the containers. The results indicated no statistically significant differences among treatments for germination, germination speed index, stem diameter, and robustness quotient. However, a significant difference was observed for shoot height, with lower growth in the treatment composed of sawdust powder. Structural evaluation indicated the occurrence of cracks and signs of biodegradation throughout the experimental period. Despite these changes, the containers maintained sufficient integrity for seedling production in the nursery, demonstrating potential as a sustainable alternative to plastic containers.
