摘要：In order to evaluate the effect of fertilization on biomass yield of the legumes Gliricidia sepium, Erythrina sp and Cratylia argentea and the non-leguminous plants Tithonia diversifolia, Morus alba and Hibiscus rosa-sinensis, an experiment was conducted at EARTH University. The experimental design used was randomized blocks with six repetitions. The arrangement of the treatments was in split-plots where the main plot was the species and the sub-plot was the fertilization treatments, which consisted of a dose with 100 kg/ha of N, 50 kg/ha P2O5 and 20 kg/ha K2O for the inorganic, and the inorganic treatment with dairy cattle manure compost of at a rate of 2 Mg/ha. The pruning frequency was 119 days between the two trials. C. argentea reported the best yield with 1.83 kg/plant of dry matter (DM) and H. rosa-sinensis produced the lowest yield with 0.07 kg/plant of DM. In fertility treatments there was no significant report of the differences in any of the variables evaluated, possibly because the applied dose was not sufficient for these shrubs.
