“…Mientras que las plantas que presentaron la menor altura fueron las del extracto E1. La literatura señala que la combinación de extractos de algas pardas es ideal en la producción de cultivos, como el estudio realizado por Sujatha et al (2015) quienes reportan la aplicación de un complejo de algas pardas, incluidas Sargassum, con las que obtuvieron una inducción del crecimiento de plantas de chile verde, nabos y piña, bajo condiciones de desarrollo normales.…”

Fusarium oxysporum es uno de los patógenos más destructivos con gran distribución y efectos devastadores en hortalizas. Una alternativa para mitigar el daño por F. oxysporum es el uso de bioestimulantes, ya que promueven una respuesta de defensa en situaciones de estrés. El objetivo del presente trabajo fue evaluar el potencial bioestimulante de extractos hidroalcohólicos de Sargassum spp. (SAR) para incrementar la tolerancia a la infección por F. oxysporum en plántulas de tomate. En total se evaluaron 17 extractos, los cuales se aplicaron de manera foliar a las plántulas a los 7, 12, 22, 33 y 43 ddt (días después del trasplante). La inducción de tolerancia de los extractos de SAR se evaluó en términos de incidencia y severidad de la enfermedad y variables agronómicas. El extracto E12 mostró un mejor control de la enfermedad con un 17% menos de la severidad de síntomas respecto al testigo infectado.

“…Sargassum liquid fertilizer (SLF) is the best alternative due to some positive impacts including biochemical content, the plant growth rate, crops, and land productivity [4], [5], and [6]. In addition, SLF production is more economically efficient than the other sargassum based manufactures such as food and drug production.…”

Sargassum can be used as an alternative material for liquid organic fertilizer production. Liquid organic fertilizer is more environmental-friendly than the synthetic one. In the previous research, we have reported that Sargassum from Lange Beach (Aceh Besar, Aceh, Indonesia) was potential as a source of nutrients for plants. This current work aims to evaluate the levels of plants growth hormones including auxin, cytokinin, and gibberellin. Furthermore, we also evaluated the levels of macronutrients of the Sargassum liquid fertilizer (SLF) obtained from a twenty-five-day fermentation compared with the Indonesian Agricultural Ministry Regulation of Permentan no. 70/SR./140/10/2011. Using a high-performance liquid chromatography (HPLC) analysis, we reported that the levels of auxin, cytokinin, and gibberellin were 2.546 ± 0.399 ppm; 130.093 ± 0.378 ppm; and 13.456 ± 0.783 ppm, respectively. In addition, the contents of nitrogen (N), phosphorus (P), and potassium (K) as macronutrients were 1.79 ± 0.25 %; 0.025 ± 0.005 %; and 0.15 ± 0 %, respectively. Our study also measured the physical parameters of the reactor, such as temperature and humidity, when the production was taking place. Reactor temperature during the production process was in between 31 and 32°C. Meanwhile, the humidity was in between 87 and 89%. In conclusion, this work demonstrated that SLF produced from Lange’s Sargassum had sufficient nutrients needed by plants according to the national regulation.

Sargassum is known to have potential ingredients, such as essential nutrients and minerals, which are important for agroindustry and the environment. This study aims to determine the proximate properties of Sargassum polycystum C.A. Agardh from Lange beach and the optimum extraction period arising the liquid product. The dried seaweed was extracted using 0.1% KOH at a constant temperature of 80°C for 120–600 mins. Furthermore, nutrients content, pH, electrical conductivity (EC) and total dissolved solids (TDS) of the afforded filtrate were quantified. As a result, the moisture, ash, fibre, carbohydrate, protein, and fat content were 7.16, 13.057, 20.33, 51.77, 6.12, and 1.57%, respectively. The value of pH, EC, and TDS ranged around 4.69–7.27, 0.013–0.078 dS.m-1, and 6.24–39.75 mg.L-1, respectively. The level of N, P, K, and organic C, were estimated around 0.30–0.81, 0.16–0.28, 0.15–0.20, and 0.32–0.80%, respectively. Meanwhile, the content of Na, Mg, Ca, Fe, Mn, and Zn were observed from 112.04–212.61, 24.60–33.57, 146.59–280.92, 416.22–630.69, 18.25–27.73, and 19.86–26.53 ppm, respectively. In conclusion, extraction for 120 mins seems to be preferable, as the observed parameters were above the minimum range.
