FERMENTED SEAWEED (Kappaphycus alverezii) BY-PRODUCT PROMOTES GROWTH AND DEVELOPMENT OF LETTUCE...

Seaweed processing into juice extraction yields a considerable volume by product, with 800 grammes (80 percent) of residue going to waste following the extraction from a kilo of seaweed (Kappaphycus alverezii). The goal of this study was to employ Fermented Marine Macro Algae Residue to boost lettuce growth and yield in terms of height, growth rate, leaf length, and above and below ground fresh weight. A commercially available seaweed-based fertiliser (10ml/L) was compared to solid seaweed sludge (by-product of fermentation at 10tons/ha), fermented liquid seaweed (10ml/L), and a mix of both.Plant height after five days following transplanting for lettuce (Lactuca sativa var. Curly Green) indicated that seaweed sludge (solid seaweed fertiliser) outperformed commercial fertiliser at 10.010.72SE cm and 6.280.0.57SE cm, respectively. On the 20th day, the plants with the tallest plants (plant height) and the longest leaves (13.870.42SE cm and 15.430.54SE cm, respectively) were created using a mixture of liquid and solid seaweed fertiliser. With a combination application of liquid and solid seaweed fertiliser at 5.310.444SE cm, the fastest growth rate was achieved between 16 and 20 days.The highest growth rate was achieved by using solid seaweed fertiliser alone from transplanting (0-5 days) (4.080.44SE cm/5-days). Liquid fertiliser application resulted in almost three times larger above ground weight (270.17163.61SE g/plant) than all other treatments with equivalent below ground weight. As a result, waste products from the processing of seaweed-based beverages can be used as fertiliser in both liquid and solid form, and more significantly, in combination, for the production of lettuce.
