“…Our findings also revealed that using T. ornate as a DAB resulted in a significant increase in potato yield only at location 2, which was accompanied by a noticeable increase in soil P and plant N. This observation is consistent with the findings of Uthirapandi et al ( 2018 ) and Karthik et al ( 2020 ). Although T. ornate liquid extract had a distinct hormonal composition with a higher amount of phytohormones (e.g., auxin, gibberellin, and cytokinin).…”

“…Although T. ornate liquid extract had a distinct hormonal composition with a higher amount of phytohormones (e.g., auxin, gibberellin, and cytokinin). The use of liquid fertilizer derived from T. ornate increased plant growth and improved the biochemical composition of starch, glucose, protein, and chlorophyll a and b contents in Ocimum sanctum (Uthirapandi et al 2018 ), as well as significantly improving the growth performance of Raphanus sativus, Phaseolus vulgaris , and Vigna radiata (Karthik et al 2020 ). In the present study, we observed that DABs of T. ornate , and a mixed dry mass of C. racemosa with C. myrica showed greater disease suppression when compared to foliar application.…”

Background Ralstonia solanacearum causes potato brown rot disease, resulting in lower crop’s production and quality. A sustainable and eco-friendly method for controlling the disease is required. Algae’s bioactive chemicals have shown the potential to enhance plant defenses. For the first time, the efficacy of foliar application of Acanthophora spicifera and Spirulina platensis seaweed extracts, along with the utilization of dried algal biomasses (DABs) of Turbinaria ornata and a mixture of Caulerpa racemosa and Cystoseira myrica (1:1)on potato yield and brown rot suppression were investigated under field conditions. Field experiments were conducted in three locations: Location 1 (Kafr Shukr district, Kaliobeya governorate), Location 2 (Moneira district, Kaliobeya governorate), and Location 3 (Talia district, Minufyia governorate). Locations 1 and 2 were naturally infested with the pathogen, while location 3 was not. The study evaluated potato yield, plant nutritive status and antioxidants, soil available nitrogen-phosphorus-potassium (N-P-K), and organic matter percentage. Additionally, the shift in soil microbial diversity related to R. solanacearum suppression was examined for the most effective treatment. Results The results revealed that seaweed extracts significantly increased potato yield at all locations, which correlated with higher phosphorus absorption, while T. ornate DAB increased potato yield only at location 2, accompanied by noticeable increases in soil nitrogen and plant phosphorus. The mixed DABs of C. racemosa and C. myrica demonstrated greater disease suppression than foliar applications. The disease-suppressive effect of the mixed DABs was accompanied by significant increases in flavonoids and total antioxidant capacity (TAC). Moreover, the application of mixed DABs increased soil bacterial biodiversity, with a higher abundance of oligotrophic marine bacterial species such as Sphingopyxis alaskensis and growth-promoting species like Glutamicibacter arilaitensis, Promicromonospora sp., and Paenarthrobacter nitroguajacolicus in all three locations compared to the untreated control. Klebsiella sp., Pseudomonas putida, and P. brassicacearum abundances were increased by the mixed DABs in Location 1. These species were less abundant in locations 2 and 3, where Streptomyces sp., Bacillus sp., and Sphingobium vermicomposti were prevalent. Conclusions The results demonstrated that the used seaweed extracts improved potato yield and phosphorous absorption, while the mixed DABs potentially contributed in disease suppression and improved soil microbial diversity.

“…The lady's finger (Abelmoschus esculentus) seeds were treated with seagrass extract in the form of foliar spray (FS) and soil drench (SD), recorded increased pods and number of flowers by FS, whereas enhanced weight and length of pods by SD, and suggested the marine plants as an alternate source of bio-stimulants for organic farming (Muniswami et al, 2021). Foliar sprays of seaweed mixtures are known to substantially increase growth and biochemical parameters in Ocimum sanctum when treated with a combination of Turbinaria ornata, Sargassum wightii and Caulerpa racemosa (Uthirapandi et al, 2018). The treatment of seaweed mixture was also proven to reduce heavy metal pollutants.…”

Seaweed and seagrass contain plant growth hormones and mineral nutrients such as proteins, lipids, amino acids, phytohormones, carbohydrates, antimicrobial compounds and osmoprotectants. Hence, the present work was undertaken to assess the potential of marine plant-based bio-fertilizer, prepared as a mixture of six seaweed species and three seagrass species, in comparison with goat manure fertilizer, mixed fertilizer, conventional fertilizer and no-fertilizer (control) applications on the growth and yield of tomato (Solanum lycopersicum) under greenhouse conditions. The trial was designed in a split plot with a randomized complete block design. Fifteen biological replications were used from each row for measuring plant height, number of fruits and fruit weight. In this study, treatment of conventional fertilizer, marine plant bio-fertilizer, goat manure, mixed fertilizer and control was applied. This study revealed that tomato plants supplied with conventional fertilizers had the highest plant height and the highest number of fruits, while the plants treated with marine plant bio-fertilizer produced fruits of the highest weight. This is the first study on the utility of marine plant as bio-stimulants for agricultural production in Somalia. The application of eco-friendly and user-friendly marine bio-fertilizers can be suggested to farmers in getting higher yields and better growth of tomato plants.
