The purpose of this study was to evaluate the use of biochar and partial peeling of the stems to accelerate the germination of Erythrina Variegata stem cuttings. The experiment was designed as a 2*5 factorial in a completely randomized design (CRD) with four replicates. The factors were: 1. Peeling of stem (P: Peeled, N: Not peeled); 2. Biochar levels of 0, 1, 2, 3 and 4 % of soil. The trial was conducted in the field laboratory of the Research and Technology Transfer Center, in Nong Lam University, Vietnam, from May to July 2015. Peeling was by scraping off the epidermis of the bottom 3cm of the stake cuttings. The cuttings were planted in soil in plastic bags (2 liter capacity). Biochar improved soil fertility, with greater water holding capacity and increase in pH. Rate of germination of Erythrina cuttings was increased by biochar and by peeling the stems. Key words: pH, organic matter, water holding capacity
