The Effect of Empty Oil Palm Fruit Bunch Compost on the Growth and Production of Romaine Lettuce (Lactuca sativa L.)

Abstract
Background: Excessive use of inorganic fertilizers can degrade soil quality and the environment, highlighting the need for alternative fertilization strategies. Organic fertilizers, such as compost derived from empty oil palm fruit bunches (Empty Fruit Bunches/EFB), a solid by-product of the palm oil processing industry, offer potential benefits for sustainable vegetable cultivation. EFB compost is considered a promising organic fertilizer due to its nutrient content and ability to improve soil properties.
Aims: This study aimed to determine the effect of empty oil palm fruit bunch (EFB) compost application on the growth and production of romaine lettuce (Lactuca sativa var. longifolia).
Methods: The study was conducted from August to October 2023 at the Faculty of Agriculture's experimental garden at Muhammadiyah University of Jakarta. The experiment employed a Completely Randomized Block Design (CRBD) with five treatments: NPK fertilizer at 0.75 g per polybag as the control, and EFB compost at 50, 100, 150, and 200 g per polybag. Growth and yield parameters were observed to evaluate the response of romaine lettuce to the different fertilization treatments.
Result & Conclusion: The results showed that EFB compost at all tested doses produced effects comparable to those of the NPK treatment across all observed parameters. Among the treatments, the application of EFB compost at a dose of 100 g per polybag was identified as the most effective in supporting the growth and production of romaine lettuce plants.
