This study was conducted to determine the potential of agricultural waste such as carbonized rice hull (CRH) liquid extract as a source of silica and other nutrients for cucumber production. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three treatments and three replications. The treatments were 1) full recommended rate inorganic fertilizer (RRIF), 2) full RRIF plus RHA liquid extract and 3) half RRIF plus RHA liquid extract. Plots treated with liquid extract gave significant results compared with the RRIF alone, however, treatment 2 and 3 were comparable. This implies that application of half RRIF could meet the nutrient requirement of cucumber when applied with supplemental liquid extracts from carbonized rice hull. Further study on the effects of this liquid fertilizer for other crops is therefore recommended.
