The Growth of Oil Palm Seeds (<em>Elaeis guineensis</em> Jacq.) at Main Nursery through Giving Biofertilizers Consortium of Cellulolytic Bacteria

Abstract

Oil palm (Elaeis guineensis Jacq.) plays a very strategic role in the economy in Indonesia. Plants that have reached economic age of 25 years need to be rejuvenated by replacing quality oil palm seeds. Quality seeds are obtained through proper fertilization. One of the efforts that can be done is to utilize biofertilizers based on cellulolytic bacteria and combined with organic liquid waste. This study aims to obtain the best formulation of organic liquid waste-based cellulolytic bacteria for the growth of oil palm seeds (Elaeis guineensis Jacq.) in the main nursery. This study used a Complete Randomized Design consisting of 12 treatments namely (20, 30, 40) ml of rice washing water biofertilizer, (20, 30, 40) ml of coconut water biofertilizer, (20, 30, 40) ml of tofu waste biofertilizer, (20,30,40) ml of liquid waste of oil palm biofertilizer. The results showed that the provision of biofertilizers based on all organic liquid waste with various doses does not affect all the observation parameters of oil palm growth. However, the use of biofertilizers with various organic materials can be applied to oil palm plants to reduce the use of inorganic fertilizers.
