“…The application of U. rigida extract significantly enhanced the growth, and rooting capacity of carob hypocotyl cuttings. These results are in agreement with those of previous studies using seaweed extract to stimulate the growth of crops such as mung bean [16], cucumber [17], Sour Orange [18], and lettuce [19]. A chemical analysis of algae and their extracts noted the presence of carbohydrates, macro and microelements, phenylacetic acid, vitamins, and plant growth regulators such as auxin and cytokinins [20][21][22][23].…”

“…This was reported in tomato and sweet pepper plants treated with extracts of A. nodosum , S. vulgare , and A. spicifera [ 5 , 13 ]. Apart from increasing harvestable crop yield, extracts have been reported to enhance the nutrient quality of crops such as tomato, pepper, lettuce, spinach, cucumber, and strawberry [ 6 , 12 , 37 , 38 , 39 ]. Treatment of cucumber with an extract of Macrocystis pyrifera led to significant increases in total phenols, antioxidant capacity, and vitamin C in the fruits [ 39 ].…”

The use of seaweed-based bioproducts has been gaining momentum in crop production systems owing to their unique bioactive components and effects. They have phytostimulatory properties that result in increased plant growth and yield parameters in several important crop plants. They have phytoelicitor activity as their components evoke defense responses in plants that contribute to resistance to several pests, diseases, and abiotic stresses including drought, salinity, and cold. This is often linked to the upregulation of important defense-related genes and pathways in the plant system, priming the plant defenses against future attacks. They also evoke phytohormonal responses due to their specific components and interaction with plant growth regulation. Treatment by seaweed extracts and products also causes significant changes in the microbiome components of soil and plant in support of sustainable plant growth. Seaweed extracts contain a plethora of substances which are mostly organic, but trace levels of inorganic nutrient elements are also present. Fractionation of seaweed extracts into their components and their respective bioassays, however, has not yielded favorable growth effects. Only the whole seaweed extracts have been consistently proven to be very effective, which highlights the role of multiple components and their complex interactive effects on plant growth processes. Since seaweed extracts are highly organic, they are ideally suited for organic farming and environmentally sensitive crop production. They are also very compatible with other crop inputs, paving the way for an integrated management approach geared towards sustainability. The current review discusses the growth and functional effects evoked by seaweed extracts and their modes and mechanisms of action in crop plants which are responsible for elicitor and phytostimulatory activities. The review further analyses the potential value of seaweed extracts in integrated crop management systems towards sustainable crop production.

“…Yusuf et al 24 stated that, the application of seaweed extract resulted in a higher chlorophyll content compared to the control treatment, which they attributed to the seaweed extractʼs betaines reducing chlorophyll breakdown. Also, Ashour et al 21 found that, using seaweed extract (commercially called True-Algae-Max, TAM®) on C. annuum at different concentrations improved significantly yield components of the plant in addition to increasing the amounts of chlorophyll, ascorbic acid, flavonoids and total nutrients.…”

Background and Objective: Borage is a medicinal plant with different culinary and medicinal uses. It is also cultivated for commercial oil production. Little information is available regarding the influence of the type of fertilizer on borage performance under different environmental conditions. Therefore, there is a need to determine the impact of some fertilizers such as seaweed and NPK on several agronomic parameters. Materials and Methods: Fertilizer treatments include seaweed (2 g LG 1 ) and NPK (2 g LG 1 ) in addition to control.The study was conducted using a completely randomized design with three replications. Results: Results showed that both types of fertilizers significantly increased plant traits measured over the control. Some of those traits included, plant height, vegetative biomass, chlorophyll content, seed yield and harvest index. Conclusion: It can be concluded that applying these fertilizers was beneficial in increasing vegetative growth as well as seed yield of borage.
