Initial Development of Tree Species in Silvopastoral System in Southern Brazil

Abstract

The selection of adapted tree species is fundamental for the success of silvopastoral systems. The present study aimed to evaluate the initial development of native trees seedlings planted on pastureland chosen by their economic value and nitrogen retrieval. The seedlings were planted in strips containing three lines. Between each strip there was an area of 15 m with pasture. From the measurements of tree height, diameter at the base, damage by insects or by diseases, it was reported the best performances for canafístula (Peltophorum dubium), pau-jacaré (Piptadenia gonoacantha), mutambo (Guazuma ulmifolia) and capixingui (Croton floribundus). Ipê-felpudo (Zeyheria tuberculosa) showed the worst performance of all under the conditions evaluated. Survival rate in eleven months for pau-jacaré was under 50%.
