COMBINATION OF LIQUID ORGANIC FERTILIZER OF ARENGA PALM [ARENGA PINNATA (WURMB) MERR] AND WATER HYACINTH (EICHHORNIA CRASSIPES) IN SUSTAINABLE AGRICULTURE SYSTEM ON GROWTH AND YIELD OF RICE PLANTS

Abstract

The higher the public awareness of the need for healthy food, which is free from chemicals, the more efforts are made to overcome it, including using organic fertilizers. This study aims to get the best results from the combination of palm sap [Arenga pinnata (WURMB) MERR] and water hyacinth on the growth and yield of paddy fields. This study used a single-factor randomized block design (RBD) consisting of 6 treatment levels, namely A0 = control (without giving SAP), A1 = 20 ml palm sap + 80 ml water hyacinth + 900 ml water, A2 = 30 ml palm sap + 70 ml water hyacinth + 900 ml water, A3 = 50 ml palm sap + 50 ml water hyacinth + 900 ml water, A4 = 60 ml palm sap + 40 ml water hyacinth +900 ml water, A 5 = 70 ml palm sap + 30 ml water hyacinth +900 ml of water. Based on the results of the study, the combination of palm sap and water hyacinth had an effect on plant height (92.98 cm), the number of tillers (15.78 tillers), panicle length (28 – 29 cm), and seed weight per panicle (4.4 g – 5 g. Panicle-1), and the weight of 1000 grains 29.17 g. The combination of palm sap [Arenga pinnata (WURMB) MERR] and water hyacinth can increase the growth and yield of paddy rice plants.
