Para tal foi realizado um experimento conduzido, durante 150 dias, em casa de vegetação, cujo delineamento foi em blocos ao acaso com arranjo fatorial 6 x (3+1) (6 espécies arbóreas,<span style="mso-spacerun: yes;">  </span>3 materiais orgânicos e 1 controle), com 4 repetições, perfazendo um total de 96 parcelas experimentais. Sendo as espécies aroeira (<em style="mso-bidi-font-style: normal;">Astronium fraxinifolium</em>), eucalipto (<em style="mso-bidi-font-style: normal;">Eucalyptus citriodora</em>), ipê roxo (<em style="mso-bidi-font-style: normal;">Tabebuia impetiginosa</em>), leucena (<em style="mso-bidi-font-style: normal;">Leucena leucocephala</em>), nim (<em style="mso-bidi-font-style: normal;">Azadirachta indica A. Juss</em>), sabiá (<em style="mso-bidi-font-style: normal;">Mimosa caesalpinaefolia</em>). O material orgânico composto de esterco bovino, esterco ovino e esterco de aves e um controle representado pelo estéril. Avaliou-se altura, diâmetro do caule, produção de matéria seca na planta. tanto o controle como os tratamentos com adição de esterco, responderam positivamente. Economicamente é mais viável o uso do controle. As espécies arbóreas mais recomendadas são: Nim, Leucena, Aroeira e Ipê-roxo.</span></p><!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" DefUnhideWhenUsed="true" DefSemiHidden="true"
