“…In the first year, the use of alga and appropriate doses (50 and 75%) of N resulted in a higher content of a green pigment (13 and 16.5% more, respectively) in comparison with 100% of N; whereas in the second year results were comparable. Spirulina applied to the soil can increase not only the chlorophyll content in the leaves, but also the content of proteins and amino acids (Bhowmik et al 2010; Osman et al 2016; Mala et al 2017), vitamin A (Mala et al 2017) and antioxidant activity of the cultivated biomass (Mala et al 2017). Higher chlorophyll content in the leaves can also result from the higher leaf area due to the action of Spirulina hydrolysate (Mógor et al 2018), or dry algal biomass used for seeds coating (Hegazi et al 2010).…”

“…In most cases, Spirulina was applied directly to the soil or was added in the form of the algal suspension. Plants biofortified with the macro- and micronutrients of cyanobacterial origin can be used as novel, functional food preventing the malnutrition (Tuhy et al 2015; Mala et al 2017). Mala et al (2017) used S. platensis as a fertilizer for agronomic biofortification of Amaranthus dubius (the red spinach) with carbohydrates, proteins, essential macronutrients, micronutrients and vitamin A. Post-extraction residues after supercritical CO 2 extraction of S .…”

In the present paper, products obtained from a blue-green microalga Spirulina platensis filtrate (applied for seed soaking and for foliar spray) and homogenate (used for seed coating) were tested in the cultivation of radish. Their effect on length, wet mass, multielemental composition and the greenness index of the radish leaves was examined. Multi-elemental analyses of the algal products, and radish were also performed using inductively coupled plasma-optical emission spectrometry (ICP-OES). The best soaking time, concentrations of filtrate and doses of homogenate were established. The longest and heaviest plants were observed for homogenate applied at a dose of 300 µL per 1.5 g of seeds and 15% of filtrate applied as foliar spray. The highest chlorophyll content was found in the group treated with 100 µL of homogenate and 5% of filtrate. In the case of soaking time, the longest plants were in the group where seeds were soaked for 6 h, but the heaviest and greenest were after soaking for 48 h. The applied algal products increased the content of elements in seedlings. Obtained results proved that algal extracts have high potential to be applied in modern horticulture and agriculture. The use of Spirulina -based products is consistent with the idea of sustainable agriculture that could help to ensure production of sufficient human food to meet the needs of rising population and protection of the environment.

“…Many abiotic factors (drought, salinity, extreme temperatures) are manifested in plants as osmotic stresses, leading to accumulation of reactive oxygen species (ROS) that damage DNA, lipids, carbohydrates, and proteins and also cause aberrant cell signaling [ 100 ]. Soil inoculation or foliar application of cyanobacterial-based biostimulants have been shown to strengthen the antioxidant activity of treated plants, thus mitigating the effects of stress-induced free radicals by direct scavenging and preventing ROS formation [ 43 , 67 , 89 , 108 ]. Singh et al [ 43 ] reported that soil inoculation with Oscillatoria acuta and Plectonema boryanum induced systemic tolerance against stress by enhancing enzymatic activity of peroxidase and phenylalanine ammonia lyase in rice leaves, while total phenolic content reached maximum values after inoculation with A. oryzae .…”

Cyanobacteria can be considered a promising source for the development of new biostimulants as they are known to produce a variety of biologically active molecules that can positively affect plant growth, nutrient use efficiency, qualitative traits of the final product, and increase plant tolerance to abiotic stresses. Moreover, the cultivation of cyanobacteria in controlled and confined systems, along with their metabolic plasticity, provides the possibility to improve and standardize composition and effects on plants of derived biostimulant extracts or hydrolysates, which is one of the most critical aspects in the production of commercial biostimulants. Faced with these opportunities, research on biostimulant properties of cyanobacteria has undergone a significant growth in recent years. However, research in this field is still scarce, especially as regards the number of investigated cyanobacterial species. Future research should focus on reducing the costs of cyanobacterial biomass production and plant treatment and on identifying the molecules that mediate the biostimulant effects in order to optimize their content and stability in the final product. Furthermore, the extension of agronomic trials to a wider number of plant species, different application doses, and environmental conditions would allow the development of tailored microbial biostimulants, thus facilitating the diffusion of these products among farmers.
