Fertilization is one of the cultural management practices to consider in increasing the yield of abaca. However, small farmers cannot afford the increasing price of inorganic fertilizer in the market, hence, the use of organic fertilizer is tried which is locally available and known to give good results when applied to crops. Biogas digester effluent (BDE) is one of the alternative sources of organic fertilizer. It is derived from the waste materials of animal residues and is available in liquid and solid forms (Barnett et al., 1978). It is used to fertilize food crops including rice, corn, and vegetables with significant results. The application of biogas residue does not only improve yield but will also reduce the cost of production of said crop. BDE was used to evaluate its effect on the growth and development of abaca variety Inosa at early stage of growth and to determine its optimun level that would give optimum growth of abaca at early stage of development. Herbage yield, stalk fresh weight and shoot dry weight were significantly higher in abaca seedlings applied with 1000ml BDE per plant. All other parameters were comparable regardless of the level of BDE and did not significantly differ with the control and inorganic fertilizer treated abaca plants.
