Crescimento de mudas de gravioleira (Anonna muricata L.) em substrato com superfosfato simples e vermicomposto

摘要

An experiment was conducted at the fruits sector of the Lavras Federal University -UFLA in order to evaluate the effect of different amounts of earthworm and simple superphosphate in the growing and nutrition of soursup seedlings (Anoma muricata L.). Four dosages of simple superphosphate (0,0; 2,5; 5,0 and 10,0 kg m-3 of substratum) and four dosages of earthworm (0,0%; 10,0%; 20,0% and 40,0% of volume) were tested at Latosol. The experimental design was randomized block in a two factors arrangement (4x4) with 4 replicates. The plants height (cm); stem diameter (cm); matter of the aerial part and roots (g per plant); number of leaves per plant and leaves area (cm2.plant-1) were evaluated. The results showed that the use of simple superphosphate at 5kg m-3 with 40,0% of earthworm provided soursup seedlings with superior quality compared to the others.
