“…Also, extracts from S. muticum and Ascophyllum nodosum at 25% concentration showed positive effects in lettuce and rice plants (Silva et al, 2019). On the other hand, a combination of T. ornata and Ulva reticulata as seaweed liquid fertilizer showed better plant growth and seed germination of Phaseolus vulgaris (Green Pea), Raphanus sativus (Radish), and Vigna radiata (Mung) (Karthik et al, 2020). Similarly, the liquid extract of T. murayana has been shown as an effective bio-fertilizer on tomato plants (Lycopersicum esculentum) by significantly improving the fruit and flower numbers (Sunarpi et al, 2020).…”

“…As originally initiated by Milton in 1952, SLE is now well utilized to enrich crops in agriculture and horticulture (Hurtado et al, 2009). Sargassum and Turbinaria species have been utilized as SLE for crops, which according to studies, showed remarkable growth, yield, quality, and other properties of crops (Zodape et al, 2008;Erulan et al, 2009;Kumari et al, 2011;Kavipriya et al, 2011;Vijayanand et al, 2014;Selvam and Sivakumar, 2014;Nabti et al, 2017;Layek et al, 2018;Manea and Abbas, 2018;Silva et al, 2019;Sunarpi et al, 2020;Karthik et al, 2020;Ali et al, 2021).…”

Kappaphycus striatus is one of the most important eucheumatoid species that is widely farmed worldwide. In the southern Philippines, where the initial farm was established, sluggish growth of farmed Kappaphycus species brought about by the poor quality of planting materials and extensive farming resulting in unproductive farms and frequent ice-ice outbreaks have been a hindrance in increasing the seaweed production. As a result, farmers have led to the application of inorganic fertilizers as nutrient enrichment for Kappaphycus. However, inorganic or chemical fertilizers always pose negative impacts on the environment. Hence, in this study, a preliminary investigation on the potential use of extracts of brown seaweeds Sargassum cristaefolium and Turbinaria conoides as bio-fertilizers was tested on K. striatus for their growth rate, carrageenan yield, and ice-ice disease occurrence. Seaweed liquid extracts (SLE): S. cristaefolium (SC), T. conoides (TC), combination of SC and TC (MX), and control (C) were utilized as bio-fertilizers for K. striatus. SLE-enriched K. striatus seedlings were cultivated in a seaweed farm using the fixed-off bottom method for 45 days. Results revealed that the specific growth rates of all SLE treatments were significantly higher than no SLE treatment at day 45. The percentage of ice-ice disease and the yield of carrageenan did not differ among treatments. Enrichment of K. striatus using SLE of two selected brown seaweeds before out-planting could improve growth rates while not affecting the ice-ice disease occurrence and carrageenan yield. Hence, formulated SLE from brown seaweeds S. cristaefolium and T. conoides can be used as potential bio-fertilizers for Kappaphycus cultivation.

“…Therefore, the stimulation of α-amylase is important in order to maintain an active respiratory metabolism, which permits the germination of plant seeds. The combinations of Turbinaria ornata and Ulva reticulate enhanced the germination and growth parameters of radish, green pea, and mung [79]. The amylase activity is calculated as the mg reducing sugars.…”

Seaweeds can play a vital role in plant growth promotion. Two concentrations (5 and 10 mg/mL) of soluble polysaccharides extracted from the green macroalgae Ulva fasciata and Ulva lactuca were tested on Zea mays L. The carbohydrate and protein contents, and antioxidant activities (phenols, ascorbic, peroxidase, and catalase) were measured, as well as the protein banding patterns. The soluble polysaccharides at 5 mg/mL had the greatest effect on the base of all of the parameters. The highest effects of soluble polysaccharides on the Zea mays were 38.453, 96.76, 4, 835, 1.658, 7.462, and 38615.19, mg/mL for carbohydrates, proteins, phenol, µg ascorbic/mL, mg peroxidase/g dry tissue, and units/g tissue of catalase, respectively. The total number of protein bands (as determined by SDS PAGE) was not changed, but the density of the bands was correlated to the treatments. The highest band density and promoting effect were correlated to 5 mg/mL soluble polysaccharide treatments extracted from Ulva fasciata in Zea mays, which can be used as a biofertilizer.

Extensive use of chemical fertilizer is leading to infertility of soil and various hazardous effect on the ecosystem. Using biofertilizer reduces these harmful effects. Many are commercially available, being a poor match to chemical fertilizer they are not used on a large scale. Near coastal regions seaweeds are used as biofertilizers. Recent studies show seaweeds have multiple growth regulators, macro and micronutrients, polysaccharides which are necessary for plant growth. The study is carried out to check the bioactivity of Seaweed liquid fertilizer (SLF) as a growth stimulant. Sargassum cinereum, Ulva rigida and Ahnfeltia plicata found on the Indian coastline were used. SLFs were prepared from each of three species in varying concentration (0.02%, 0.04%, 0.06%, 0.08% and 0.1% v/v) with water and Urea as control. The test plant selected was Vigna radiata. Agronomic characters like germination rate, shoot length, flowering and fruiting period of test plants were studied. Phyto-hormones from SLF were detected by thin-layer chromatography. Elemental analysis of micronutrients in SLF was carried by ICP-AES. Along with Chlorophyll and Protein estimation of grown plants were checked. SLF shelf life was studied using chemical and biological preservatives. The effect of 0.06% concentration of all SLFs showed enhancement in growth and phytochemicals in plants. Plants treated with SLF showed flowering earlier than control plants. Thus, using SLF bio-fertilizer can become an alternative method to reduce the use of harmful chemical fertilizers.
