The effect of five growing media, in different proportions of subsoil, limestone, and sugar cane bagasse ash, in the height, stem diameter, and fresh and dry weight of the aerial part and roots of araticum seedlings (Annona crassiflora Mart.) was analyzed. The five growing media were: pure soil; pure soil with limestone; soil + 1/3 of its volume with ash; soil + 1/3 of its volume with ash + limestone; and soil + 2/3 of its volume with ash. The experiment was conducted in a greenhouse, in Goiânia, State of Goiás, Brazil, from February through October, 2003, with 50% of shadow, in a randomized block design, with a 2 x 2 + 1 factorial scheme. It was observed that none of the growing media resulted in different growth and stem diameter of the seedlings. However, the positive effect of limestone application was observed in the fresh and dry weight of the aerial part of the seedlings. The application of sugar cane bagasse ash showed to be harmful to the development of the seedlings.
