The Growth of Rice Plants on Combination of Liquid Organic Fertilizer Based of the Water Hyacinth

Aims: This study aims to obtain a combination of liquid organic fertilizer (LOF) concentrations of palm wine and water hyacinth on the growth of rice plants.

Study Design: This research used a randomized block design with thri (3 replications).

Place and Duration of Study: This research was conducted in Baolan District, Tolitoli Regency, Central Sulawesi Province with an altitude of 20 meters above sea level (MSL) from September 2022 to January 2023.

Methodology: consisting of six treatments, namely Ao = control, A1 = 80 ml LOF of water hyacinth + 20 ml LOF of palm wine + 900 ml of water, A2 = 70 ml LOF of water hyacinth + 30 ml palm wine + 900 ml water, A3 = 50 ml water hyacinth + 50 ml palm wine + 900 ml water, A4 = 40 ml water hyacinth +60 ml palm wine + 900 ml water, A 5 = 30 ml water hyacinth + 70 ml of palm wine + 900 ml of water. Each treatment was applied to the pot as media and each pot was planted with 1 seed.

Results: The results of the study was shown that the combination of water hyacinth and palm wine had a significant effect on plant height, number of tillers, panicle length and grain weight per panicle.

Conclusion: Application of liquid organic fertilizer with a combination of water hyacinth and palm wine can increase rice plant growth, increase the number of tillers, panicle length and seed weight per panicle.
