Improvement of Health and Vigor of Hybrid Cacao (Theobroma cacao L.) Seedling through Incorporation of Trichoderma spp. in Seed Matriconditioning and Planting Media

Abstract

Our study In hybrid cacao seed showed that there were 13 species of fungal pathogens reducing seed vigor and cacao seedling (Baharudin ef al. 2012). Application of seed treatment using matriconditioning plus Trichoderma harzianum DT/38 and T. pseudokoningli DT/39 Improved viability and vigor of hybrid cacao seed (Baharudin et al. 2010). This Invigoration treatment using matriconditioning plus biological agents has been defined as biomatricondltioning (Ilyas and Sepian 2013). Use of planting media consist of soil:sand:organic matter (2:1:1) plus Trichoderma spp. is good for growth of coffea and cacao seedlings (Prawoto 2008)
