SEAWEED LIQUID FERTILIZER (SLF) AND ITS ROLE IN AGRICULTURE PRODUCTIVITY

Conference: National Seminar on Ecology and Enviroment, Volume: Special Issue

ABSTRACT Seaweeds or marine macro-algae are important renewable plant resources occurring in the seas, brackish waters and lagoons across the globe. Application of liquid extract from these organisms as foliar spray and/or seed treatment showed positive result on enhancement of vegetative growth and yield of several crops. In addition they increase the biochemical constituents of plants and possess environmental stress mitigating potential. Amendment of seaweed liquid fertilizer (SLF) to soils improves the soil health by enhancing the micronutrient quantity and quality, and microbial activity. The research work carried out so far on the beneficial role of SLF in agriculture has been reviewed. The seaweed resources of the Indian coast and the methods so far followed for preparation of SLF and their mode of application to crops is presented.

    ABSTRACT: The effect of different concentrations (20%, 40% 60%, 80% and 100%) of seaweed liquid fertilizer (SLF) of Sargassum wightii on the growth and biochemical characteristics of Abelmoschus esculentus was studied. The low concentration (20%) of S. wightii extract promoted the shoot length, root length, fresh weight, dry weight, chlorophyll, carotenoid, protein, amino acid, reducing sugar, total sugar, α-amylase and β-amylase activities in Abelmoschus esculentus.

    ABSTRACT: Recently the researchers found that an extract of Fucus vesiculosus, which is a type of seaweed, promotes the contraction of fibroblast-populated collagen gels through increased expression of integrin molecules. In this study, they investigated the effects of topical application of an aqueous extract of this alga on the thickness and the mechanical properties of human skin. A gel formulation that included 1% of the extract was applied topically to human cheek skin twice daily for five weeks. A significant decrease in skin thickness measured by B-mode ultrasound was elicited, as was a significant improvement in elasticity measured with a Cutometer as compared with controls. In cheek skin, the thickness normally increases and the elasticity usually decreases with age. These results suggest that the Fucus vesiculosus extract possesses anti-aging activities and should be useful for a variety of cosmetics.

    ABSTRACT: Experiments were conducted on tomato to study the potential of brown alga Sargassum johnstonii as a biofertilizer. Seaweed extract was applied as a foliar spray, soil drench, and soil drench + foliar spray to assess its effect on plant growth, yield, and concentration of lycopene and vitamin C. The main objective of the study was to enhance the biochemical constituents with neutraceutical and antioxidant values in tomato fruit. Different concentrations (0.1%, 0.4%, 0.8%, 2%, 6%, 8%, and 10%; v/v) of seaweed extract were used and growth was observed over a period of 7months. A total of 14 sprays/drenches were applied at 15-day intervals during the entire vegetative and reproductive phase. A statistically significant increase in vegetative growth (plant height, shoot length, root length, and number of branches), reproductive parameters (flower number, fruit number, and fresh weight), and biochemical constituents (photosynthetic pigments, proteins, total soluble sugars, reducing sugars, starch, phenols, lycopene, and vitamin C) was recorded following all three methods of treatment at higher concentrations of seaweed extract. The study also reports auxin- and cytokinin-like activity, and the presence of macro- (Ca, Mg, Na, and K) and micronutrients (Fe, Cu, Zn, and Mn), in seaweed extract of S. johnstonii, which makes it a potential biofertilizer.
