Summary: | Production of biochar from organic wastes promises to be an interesting source of plant nutrients, thus reducing pressure on natural resources. To assess the effect of biochar prepared from wastes filtration materials on the growth and production of common bean (Phaseolus vulgaris L.), three simultaneous greenhouse experiments were conducted with three different biochar from organic wastes (rice husk, sawdust, and sorghum silage) using as filtration material for swine biofertilizer. In each experiment the treatments consisted of the addition of five different biochar concentrations (0%, 2.5%, 5%, 7.5%, and 10% v/v), arranged in a completely random design, with four repetitions. Application of biochar increased the root dry mass, shoot dry mass, grain dry mass, number ofpods and number of grains. These results indicated that biochar contributed significantly to the growth and production of common bean plants. Key words: agricultural wastes, alternative source of nutrients, Phaseolusvulgaris L. A producao de biochar a partir de residuos organicos pode ser uma estrategia agronomica interessante como fonte de nutrientes para as plantas, diminuindo assim, a pressao sobre os recursos naturais. Com o objetivo de avaliar o efeito de biocarvoes, produzidos de materiaisfiltrantes descartados, no crescimento e producao de feijao (Phaseolus vulgaris L.), conduziram-se simultaneamente tres experimentos em casa de vegetacao. Cada um dos experimentos foi representado pela aplicacao de um biochar, os quais foram produzidos a partir de residuos organicos de casca de arroz, serragem e restos de silagem de sorgo, utilizados como material filtrante para o biofertilizante suino; e os tratamentos avaliados consistiram na adicao de cinco niveis de biocarvao, isto e, 0, 2,5%, 5% 7,5% e 10% v/v. Nos tres experimentos a aplicacao de biochar aumentou a massa seca da raiz, massa seca da parte aerea, massa seca de graos, numero de vagens e numero de graos. Esses resultados indicam que os biochars contribuiram significativamente para o crescimento e producao do feijoeiro.
