Enteromorpha intestinalis Derived Seaweed Liquid Fertilizers as Prospective Biostimulant for Glycine max

TL;DR: Results showed that E. intestinalis derived SLF was potential biostimulant for G. max, indicating that marine algae based fertilizer could be an effective and alternate to the chemical fertilizers emphasizing the need for systematic evaluation programme for SLF on various crops.
Abstract: In the present study, the potential of seaweed liquid fertilizer (SLF) of marine algae Enteromorpha intestinalis was evaluated for its effect on seed germination, yield, biochemical parameters and pigment characteristics of Glycine maxE. intestinalis was collected form Mandapam coast of Gulf of Mannar, Tamil Nadu, and the dried seaweeds were used for the preparation of SLF. G. max seeds were germinated with four different concentrations (20, 40, 60, and 100%) of SLF; its growth and yield parameters were evaluated and compared with chemical fertilizer and control. The morphological and bio-chemical parameters such as seed germination (100%), root (6.6cm) and shoot length (5.4 cm), carbohydrates (0.098 mg/g), protein (0.56 mg/g), pigment (0.444 mg/g chl a; 1.073 mg/g chl b; 3.70 mg/g carotenoids) of the plant was found maximum at a concentration of 60% SLF. The phenol content (3.25 mg/g) was maximum in 40% SLF. The GC-MS analysis of SLF revealed the presence of notable benzoic compounds involved in plant growth promotion. Results showed thatE. intestinalis derived SLF was potential biostimulant forG. max. Thus, marine algae based fertilizer could be an effective and alternate to the chemical fertilizers emphasizing the need for systematic evaluation programme for SLF on various crops.

TL;DR: In this review, scientific progress in this field was collected and critically assessed to lay grounds for further investigations and applications of seaweed extracts in agriculture.
Abstract: Seaweeds or marine macroalgae are rich in diverse compounds like lipids, proteins, carbohydrates, phytohormones, amino acids, osmoprotectants, antimicrobial compounds and minerals. Their potential for agricultural applications is used since antiquity, but recent demands of organic farming and organic food stimulated much the application of organic treatments like seaweed extracts in agriculture. The benefits of seaweeds application in agricultural field are numerous and diverse such as stimulation of seed germination, enhancement of health and growth of plants namely shoot and root elongation, improved water and nutrient uptake, frost and saline resistance, biocontrol and resistance toward phytopathogenic organisms, remediation of pollutants of contaminated soil and fertilization. In this review, scientific progress in this field was collected and critically assessed to lay grounds for further investigations and applications.

TL;DR: The best effect on the germination and chlorophyll content in seedlings had synergistic action of the static magnetic field on seeds for 3 min applied together with the extract and alternating magnetic field used for 2.5 min.
Abstract: In the present study, the effect of the static and alternating magnetic field applied individually and in combination with an algal extract on the germination of soybean seeds (Glycine max (L.) Merrill) and chlorophyll content was examined. The exposure time of seeds to the static magnetic field was 3, 6, and 12 min, whereas to the alternating magnetic field was 1, 2.5, and 5 min. The static magnetic field was obtained by means of a permanent magnets system while the alternating magnetic field by means of magnetic coils. Algal extract was produced from a freshwater macroalga-Cladophora glomerata using ultrasound homogenizer. In the germination tests, 10% extract was applied to the paper substrate before sowing. This is the first study that compares the germination of soybean seeds exposed to the static and alternating magnetic field. The best effect on the germination and chlorophyll content in seedlings had synergistic action of the static magnetic field on seeds for 3 min applied together with the extract and alternating magnetic field used for 2.5 min. It is not possible to clearly state which magnetic field better stimulated the germination of seeds, but the chlorophyll content in seedlings was much higher for alternating magnetic field.

TL;DR: In this paper, the liquid seaweed extract of green seaweed Chaetomorpha antennina (CA-LSE) was evaluated for their biostimulant activity on seed germination and growth of tomato.
Abstract: Plant nutrition serve as critical factors that influences plant growth and yield. Global fertilizer production and application is growing in surplus amounts, increasing the agricultural expenses and damaging the environment. Organic fertilizers, obtained from natural sources, encompass all essential plant nutrients. Application of aqueous seaweed extracts are regarded as potential plant biostimulant agents. The liquid seaweed extract of green seaweed Chaetomorpha antennina (CA-LSE) were evaluated for their biostimulant activity on seed germination and growth of tomato. The CA-LSEs were able to stimulate early emergence of tomato seeds, in addition to increasing their germination percentage and energy. They also exerted a positive influence on the vegetative growth, resulting in increased plant height, leaf-branch number and yield. The CA-LSEs were influence the plant's biochemical profile and displayed a linear increase in pigment contents (chlorophyll a & b and carotenoids), total soluble solids (TSS), phenols as well as ascorbic acid contents. The bio-stimulant potential was attributed to the elements present in CA-LSEs, elucidated by EDX analysis that revealed the presence of six elements (O, Na, Mg, S, Cl and Ca), that were essentially plant nutrients. These results support the bio-stimulant potential of C. antennina, which can be applied as a prospective bio-fertilizer that is economic, renewable, efficient and eco-friendly, and also can be regarded as a potential catalyst for the betterment of sustainable agricultural food production.

Abstract: Seaweeds are the important marine resources available at negligible cost and rich in diverse bioactive compounds like lipids, proteins, carbohydrates, amino acids, phytohormones, osmoprotectants, mineral nutrients and antimicrobial compounds. They are key component in food, feed, and medicine since ancient times. Recent trend of organic farming has exploited the possible application of seaweed as organic/bio-fertilizer in agriculture. Many studies have demonstrated the benefits of seaweed in enhancing the plant growth and productivity. Added to this they are known to be a promising soil conditioner, protect the plants under abiotic and biotic stress and increase plant resistance against pest and diseases. In this chapter an attempt has been made to highlight the scientific progress on usefulness of seaweed in the context of utilization in agriculture as organic fertilizer and prospects for further research and use.

TL;DR: A comprehensive review of the effect of various seaweed species and seaweed products on plant growth and development with an emphasis on the use of this renewable bioresource in sustainable agricultural systems is provided.
Abstract: Marine algal seaweed species are often regarded as an underutilized bioresource, many have been used as a source of food, industrial raw materials, and in therapeutic and botanical applications for centuries. Moreover, seaweed and seaweed-derived products have been widely used as amendments in crop production systems due to the presence of a number of plant growth-stimulating compounds. However, the biostimulatory potential of many of these products has not been fully exploited due to the lack of scientific data on growth factors present in seaweeds and their mode of action in affecting plant growth. This article provides a comprehensive review of the effect of various seaweed species and seaweed products on plant growth and development with an emphasis on the use of this renewable bioresource in sustainable agricultural systems.

TL;DR: Application to the soil of an aqueous alkaline extract of Ascophyllum nodosum resulted in higher concentrations of chlorophyll in the leaves of treated plants in comparison to control plants treated with an equivalent volume of water, suggesting strongly that the enhanced leaf chlorophyLL content of plants treatedWith seaweed extract is dependent on the betaines present.
Abstract: Application to the soil of an aqueous alkaline extract ofAscophyllum nodosum resulted in higher concentrations of chlorophyll in the leaves of treated plants in comparison to control plants treated with an equivalent volume of water. Positive results were obtained with all species tested (tomato, dwarf French bean, wheat, barley, maize). When the seaweed extract was applied as a foliar spray, similar effects on leaf chlorophyll contents were obtained, except in the case of dwarf French bean plants, for which no significant difference was recorded between test and control plants. When the betaines present in the seaweed extract were applied as a mixture in the same concentrations as those in the diluted seaweed extract (γ-aminobutyric acid betaine 0.96 mg L−1, δ-aminovaleric acid betaine 0.43 mg L−1, glycinebetaine 0.34 mg L−1), very similar leaf chlorophyll levels were recorded for the seaweed extract and betaine treated plants. This suggests strongly that the enhanced leaf chlorophyll content of plants treated with seaweed extract is dependent on the betaines present.
