Application of Liquid Organic Fertilizer to Improve Yields in System of Rice Intensification (SRI).

<b>Background and Objective:</b> Organic fertilizer is a source of nutrition for plants which is an alternative to inorganic fertilizer. Liquid organic fertilizer (LOF) which comes from coconut fiber and banana LOF which comes from banana stems from which the fruit has been removed, so that wasted plant residue can be used as fertilizer.
