Exploring Seaweed Extracts: Novel Benefits for Fruit Crops Growth

Abstract

Seaweeds are macroalgae growing under marine ecosystems and it plays diversified roles in human life. Different types of seaweeds are available and among them, the widely used ones for extraction are brown seaweeds. One of the significant plants bio-stimulants with a wide range of applications in horticulture and agriculture is seaweed extract (SE). Various methods are employed for their extraction process. The bioactive composition of SE varies according to the type or species of seaweeds and methods of extraction. It has got almost similar effects as that of phytohormones. Seaweed extract application alone or in combination with other bio-stimulants or nutrients during different crop stages are being practised in a broad group of fruit crops (temperate, sub-tropical and tropical fruit crops).  An array of research studies has also revealed that the usage of seaweed extracts is more environmentally friendly owing to their organic nature and cost-effectiveness. It has proven significant improvements on growth, yield, quality, storage and stress tolerance. Hence, the use of seaweed extract at the appropriate time and right concentration to a variety of fruit crops can support the industry's overall growth.
