Resumo: An experiment was conducted to verify the potentiality of some plant species to revegetate areas under the influence of iron mining. Field conditions were simulated laying mining overburden (soil, phyllite and rock) over the mine spoil to cultivate the plants. Four plant species and two irrigation frequencies were tested for pile covering and plant tops dry matter production. Plants showed larger dry matter production when substrate was either soil or mixtures in which soil was one of the components. Among the plants utilized, Brachiaria brizantha and Melinis minutiflora produced the larger amounts of dry matter as compared to Cajanus cajan and Panicum maximum. The frequency of irrigation markedly affected plant growth and development. P. maximum was the species with the least decrease n dry matter production with the reduction of irrigation frequency. KEY-WORDS: Iron mining revegetation; irrigation; grasses; legumes.

Foi conduzido, em casa de vegetação, um experimento para verificar a potencialidade de diversas plantas para a revegetação de áreas de mineração de ferro. Nesse sentido, procurou-se simular a condição de campo colocando-se camadas de estéreis da mina (solo, filito e rocha) sobre o rejeito da mineração para o cultivo das diversas plantas utilizadas. Testaram-se quatro espécies vegetais para recobrimento da pilha, duas freqüências de irrigação e avaliou-se a produção de matéria seca da parte aérea das plantas. As plantas apresentaram maior produção de matéria seca da parte aérea quando o substrato foi solo ou misturas nas quais o solo aparecia como componente. Dentre as plantas utilizadas, Brachiaria brizantha (brizantão) e Melinis minutiflora (capim-gordura) produziram maior quantidade de matéria seca da parte aérea do que Cajanus cajan (guandu) e Panicum maximum (capim-vencedor). A freqüência de irrigação afetou, de modo acentuado, o desenvolvimento das plantas, sendo o capimvencedor a espécie que teve menor variação de produção de matéria seca da parte aérea, sob redução na freqüência de irrigação.
