“…It is also an excellent supply of plant nutrients, such as Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca) and Magnesium (Mg) (Gardening Channel, 2020). Seaweed also contains all the 19 essential elements needed for plant growths as well as the trace elements (Andrew J.Cole et al, 2015) (Nedumaran, 2017). Seaweed extract is widely used in agriculture especially in the horticulture industry.…”

Patchouli (Pogostemon cablin Benth.) is a bushy herb native to the tropical region of Asia, and now cultivated for its essential oil usually used in perfume manufacturing. It also widely used throughout the world as treating skin conditions, relieving depression, controlling appetite, and antifungal agents. It also cultivated commercially in Tawau, Sabah for exporting purposes with average oil production up to 26-29 mt per acre in 2016. As they enter the second and third harvesting cycle, the yield started to decline and reach 2.6 mt of oil per acre. This drop-in yield is thought to be either due to soil variabilities, low nutrient levels in volcanic soil, and also diseases. Soil nutrient analysis and leaf coloration patterns are studied before conducting the study. Seaweed extract, banana peel, the mixture of Seaweed extract and banana peel, and pre-formulated 12-12-12 (N-P-K) organic fertilizer (PFF) fertilizer treatments were engaged in the Patchouli plot field experiment. Besides, the agronomical practice for the cultivation of Patchouli is well studied or documented. The pre-study showed that the study plot has a very low conductivity level, a very low level of organic Carbon and low Cation Exchange Capacity (CEC) level. Meanwhile, there were no diseases or nematode occurrences in the area. Plant height, soil pH, and soil conductivity were studied with all the four treatments that have shown a positive significant impact compared with standard estate practice. The treatments using seaweed and seaweed mixture had the highest significant level for soil conductivity with the conductivity improve from 43 to 480 micro Siemens (μS/cm) but it reduces the soil pH. Whereas, plant height data analysis showed that the seaweed mixture was significantly different compared with other treatments at a 0.05 level. Hence, we recommend the Patchouli plantation to use organic fertilizers especially seaweed-based since it is cheap and easily available in Sabah.

The current study was carried out at Rezu Khal to determine the ideal area for seaweed farming. Additionally, this investigation uncovered species of commercially productive and lucrative seaweed. Temperature, salinity, pH, dissolved oxygen (DO), conductivity, and Formazin Nephelometric Units (FNU) of surface water ranged from 20.9 to 26.2°C, 24 to 26.2‰, 6.45 to 8.5, 92 to 105%, 33,256 to 64,267 µS/cm, and 11.1 to 42.8, respectively. Phosphate-phosphorus concentrations in surface water were 2.6–7.6 mg/L, 0.04–0.12 mg/L for nitrate-nitrogen, 0.002–0.04 mg/L for nitrite-nitrogen, 0.15–0.83 mg/L for silica, and 0.13–0.28 mg/L for ammonia. Three seaweed species (Gracilaria lemaneiformis, Hypnea musciformes, and Sargassum oligocystum) were cultivated in the selected areas. Two methods (net and long-line) were used for the culture. In this study, 15–20 kg of G. lemaneiformis were harvested every 15 days using the net method. H. musciformes gained 4 to 12 kg every 15 days. Although S. oligocystum thrived nicely, it was challenging to maintain its viability. The findings of this study indicate that seaweed farming is feasible and coastal residents may participate in seasonal income-generating endeavours in coastal waters.
