<![CDATA[This study aimed to examine the effects of liquid fertilizers derived from orange, banana, and a mixture of pineapple and papaya waste on the growth and yield of water spinach. The research was conducted at the Faculty of Agriculture Experimental Garden in Trini, Trihanggo, Gamping, using a Completely Randomized Design (CRD) with three replications. The observed parameters included plant height, number of leaves, leaf length, leaf width, stem diameter, harvestable plants per m², fresh plant weight, and fresh edible weight. The results showed that fruit waste-based liquid fertilizers had no significant effects on vegetative growth, fresh plant weight, or fresh edible weight. However, the treatments significantly affected the number of harvestable plants per m². Banana, orange, and pineapple-papaya liquid fertilizers produced 92, 91, and 92 plants/m², respectively, compared with 77 plants/m² in the control treatment. These findings indicate that fruit waste-based liquid fertilizers have the potential to increase the number of harvestable water spinach plants.]]>
