“…Foliar spray of seaweed extract is a common practice to increase yield in many commercial crop (Khan et al 2009). Foliar application of mineral nutrients offers a quicker method of supplying nutrients to higher plants than other soil application method (Shah et al 2013;Nedumaran and Arulbalachandran , 2015). This may be due to active uptake of nutrients through stomatal pores instead of cuticular uptake (Fernandez and Brown, 2013).…”

Seaweed and seaweed-derived products have been widely used as bio stimulants in crop production due to presence of multiple growth regulators such as cytokinin, auxins, gibberellins, betaines, as well as presence of macronutrients such as Ca, K, P, and micronutrients like Fe, Cu, Zn, B, Mn, Co and Mo, which are necessary for plant growth and development. Numerous studies have revealed a wide range of beneficial effects of seaweed extract on plants, such as early seed germination and establishment, better crop performance and yield, inducing resistance to biotic and abiotic stress and many more. This paper is an effort to review the importance of seaweed extract on germination, production, improvement of nutritional quality of agricultural crops which helps in further study of sea weed in agriculture.

“…The use of algae biomass as a fertilizer is an ancient agricultural technique, known since Roman times and implemented for instance, in Britain, France, Spain, and especially in East Asia (e.g., China and Japan) [ 6 ]. AEs or algal derivatives (ADs) have been typically applied to soil as organic, slow-release fertilizer, and soil amendment to return nutrients (both carbon and macro-elements) and improve soil physical and biological properties.…”

Algal biomass, extracts, or derivatives have long been considered a valuable material to bring benefits to humans and cultivated plants. In the last decades, it became evident that algal formulations can induce multiple effects on crops (including an increase in biomass, yield, and quality), and that algal extracts contain a series of bioactive compounds and signaling molecules, in addition to mineral and organic nutrients. The need to reduce the non-renewable chemical input in agriculture has recently prompted an increase in the use of algal extracts as a plant biostimulant, also because of their ability to promote plant growth in suboptimal conditions such as saline environments is beneficial. In this article, we discuss some research areas that are critical for the implementation in agriculture of macro- and microalgae extracts as plant biostimulants. Specifically, we provide an overview of current knowledge and achievements about extraction methods, compositions, and action mechanisms of algal extracts, focusing on salt-stress tolerance. We also outline current limitations and possible research avenues. We conclude that the comparison and the integration of knowledge on the molecular and physiological response of plants to salt and to algal extracts should also guide the extraction procedures and application methods. The effects of algal biostimulants have been mainly investigated from an applied perspective, and the exploitation of different scientific disciplines is still much needed for the development of new sustainable strategies to increase crop tolerance to salt stress.

“…Algal extracts belong to one of the groups of biostimulants of plant growth, which according to the definition are “substances applied to plants with the aim to enhance nutrition efficiency, abiotic stress tolerance and/or crop quality traits, regardless of its nutrients content” . Bio‐farming using seaweeds has been practiced from ancient time . Seaweeds are known to be a rich source of macronutrients and trace elements necessary for the growth and enhancement of the plants.…”

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.
