Peanut (Arachis hypogaea L.) is a grain appreciated for its pleasant taste and versatility of products that can be produced from it. Because it is a rustic species, it can be cultivated in practically all Brazilian states. The disposal of solid waste by the industry presents itself as a challenge because of the high costs and space requirements for its correct destination. The search for better alternatives for the deposition of residues from the burning of biomass and efficient products of low cost for agriculture made their reutilization like corrective of fertility and acidity of the soil possible, contributing for the reduction of the contribution of polluting material for the environment. Therefore, the objective of this study was to evaluate the effect of wood ash doses (0, 6, 12, 18, 24 and 30 g dm-³) on the productive characteristics of peanut cv. IAC OL3 and IAC 503. The experiment was carried out in a completely randomized block design in a 2x6 factorial with five replications, in dystrophic Oxisol, performed in a greenhouse at the Federal University of Mato Grosso, Câmpus of Rondonópolis, MT. The addition of wood ash increased the dry mass of pod and dry mass of peanut peel. The dry mass of leaves, dry mass of grains, number of pods, number of grains per pot, dry mass of root and root volume did not show significant interaction, prioritizing the use of the lowest doses of wood ash able to increase the productivity of these variables. The study recommends ash doses between 21.19 g dm-3 and 29.78 g dm-3 in pots, depending on the need of the variable.
