Lukman (2025). Combination of liquid organic fertilizer sap of aren [Arenga pinnata (WURMB) Merr.] with water hyacinth (Eichhornia crassipes) on the growth and results of corn crops. Bulg. J. Agric. Sci., 31(5), 951–955
To address fertilizer scarcities in corn production, organic fertilizers can be derived from plants such as water hyacinth, which is typically less productive. This study will investigate the impact of combining palm sap with water hyacinth to produce a liquid organic fertilizer (LOF). P0, P1, and P2 were the four treatment doses included in the experiment, which had to be repeated five times. These dose levels were: 20 mL/L of water, 40 mL/L of Water, and 60 mL/L of water. Data analysis was carried out using a single-factor Randomized Block Design (RBD). According to the study, the palm sap LOF and water hyacinth mixture did not have a significant impact on plant height, leaf count, and stem diameter at 20, 40, 60, 90, and 120 days after planting (DAP), nor on fruit diameter and dry seed weight at those time frames. Despite this, the 60 mL/liter dose resulted in a significant increase in both ear length (24.18 cm) and weight (70.89 g). A 60 ml/liter concentration of LOF palm sap and water hyacinth is found to be effective in increasing fruit length and weight, according to the study.
