“…Our results coincide with those of El-Sheekh and El-Saied, [74], who reported that the total soluble sugars were elevated in both the shoot and root of Vicia faba with treatments of Enteromorpha intestinalis, Cladophora dalmatica, Ulva lactuca, Corollina mediterranea, Pterocladia pinnata and Jania rubens extracts. Abdel-Hamid et al [75] reported that the consortium of Chlorella vulgaris and Anabaena oryzae enhanced Jerusalem artichokes' growth, yield, and sugar contents.…”

Seaweeds can play a vital role in plant growth promotion. Two concentrations (5 and 10 mg/mL) of soluble polysaccharides extracted from the green macroalgae Ulva fasciata and Ulva lactuca were tested on Zea mays L. The carbohydrate and protein contents, and antioxidant activities (phenols, ascorbic, peroxidase, and catalase) were measured, as well as the protein banding patterns. The soluble polysaccharides at 5 mg/mL had the greatest effect on the base of all of the parameters. The highest effects of soluble polysaccharides on the Zea mays were 38.453, 96.76, 4, 835, 1.658, 7.462, and 38615.19, mg/mL for carbohydrates, proteins, phenol, µg ascorbic/mL, mg peroxidase/g dry tissue, and units/g tissue of catalase, respectively. The total number of protein bands (as determined by SDS PAGE) was not changed, but the density of the bands was correlated to the treatments. The highest band density and promoting effect were correlated to 5 mg/mL soluble polysaccharide treatments extracted from Ulva fasciata in Zea mays, which can be used as a biofertilizer.

Cultivation Practices, Adaptability and Phytochemical Composition of Jerusalem Artichoke (Helianthus tuberosus L.): A Weed with Economic Value

et al. 2021

The Jerusalem artichoke (Helianthus tuberosus L.) is a perennial weed that is cultivated for bioethanol production or pharmaceutical purposes, as its aerial parts and tubers contain several chemical compounds. This review summarizes important data on the effects of the main cultivation practices (e.g., the planting density and pattern, weed management, fertilization, irrigation, genotypes and harvest) on tuber yield and quality. The most widespread method for the propagation of the Jerusalem artichoke is planting the tubers directly in the field, with a plant density of about 33,000–47,000 plants ha−1. Weed management is based on herbicide application, mechanical cultivation and hand hoeing, while the nutrient requirements are low, and irrigation relies on weather conditions. For instance, under Mediterranean semi-arid conditions, the crops are irrigated from June to September. In addition, the harvest time depends on the genotype and the purpose of cultivation, which is an important consideration for obtaining a high-quality product. In conclusion, Jerusalem artichoke yield and quality depend on several factors, and this plant, due to its high productivity, constitutes a promising crop with numerous uses.

Microalgae-based wastewater treatment offers an eco-friendly opportunity for simultaneous nutrient recovery and biomass generation, aligning with the circular bioeconomy concept. This approach aims to utilize the nutrients of potato industry wastewater (PIW) for algal growth while mitigating the environmental impact of this industrial byproduct. This study focused on cultivating three cyanobacterial strains, Anabaena oryzae, Nostoc muscorum, and Spirulina platensis, in PIW and synthetic media for 30 days to assess feasibility. Growth performance was monitored by measuring chlorophyll content, dry weight (DW), optical density (OD), and pH at 3-day intervals. The high-performing cyanobacterial biomass from the laboratory findings was formulated into a biofertilizer, which was then evaluated in a controlled greenhouse experiment on celery and lettuce plants. The biofertilizer replaced conventional NPK mineral fertilizers at different levels (25%, 50%, and 75%), while a control group received 100% chemical fertilizer. The results showed favourable growth of all three cyanobacteria strains and their mixture in PIW throughout the experiment. The mixed cyanobacteria followed by Spirulina platensis exhibited the highest growth rates, achieving chlorophyll contents of 3.75 and 2.30 µg·mL−1, DWs of 1.79 g·L−1 and 1.63 g·L−1, and ODs of 0.41 and 0.38, respectively, surpassing the other treatments. The formulated biofertilizers, Spi-PIW (Spirulina platensis + potato industry wastewater) and Cyano-PIW (mixed culture+ potato industry wastewater), significantly enhanced plant height, root and stem lengths, and the number of leaves per plant in celery and lettuce compared to the control group. These biofertilizer treatments also improved chlorophyll contents, as well as macro- and micronutrient levels, in the two crops. Additionally, the application of these biofertilizers improved certain sandy soil properties, i.e., pH, total organic matter, total nitrogen, phosphorus, and potassium. In conclusion, utilizing PIW as a substrate for cultivating cyanobacteria strains and producing high-quality liquid bio-organic fertilizers holds potential for reducing recommended NPK fertilizer doses by 25–50% in celery and lettuce growth, providing an environmentally friendly approach.
