“…The major of seaweed-based biostimulants are extracted from brown macroalgae (e.g., Ascophyllum nodosum, Durvillaea spp., Ecklonia maxima and Sargassum spp.,) and from the red macroalgae (e.g., Kappaphycus alvarezii, Gracilaria spp. and some coralline algae belonging to the family Lithothamniaceae) [4,8,19,20]. Profertil® is a solution with biostimulant effects that can be used in organic farming, it is based on extracts of European A. nodosum.…”

Background:The common bean (Phaseolus vulgaris L.), is one of the most relevant legumes worldwide, as a source of protein, fiber, carbohydrates, and biologically important minerals. In recent decades, bean production increased significantly, especially in developing countries, where the availability of animal protein is often in short supply. However, a large portion of this agricultural production has been achieved in an unsustainable manner, through the intensive use of non-renewable agrochemicals, which in both the short and long term negatively affect soil fertility. To address this problem, the use of sustainable and renewable bio-inputs derived from macroalgae, and microorganisms may be amongst solutions required. Extracts of seaweeds have been shown to be biodegradable and non-toxic both for treated plants and consumers. This study aimed to evaluate the influence of the application of three bio-inputs made from different organisms on a common bean variety (BRSMG Realce) by analysing plant physiology and productivity, pod morphology, nutritional and mineral characterization of the bean. The study also aimed to evaluate the length of BRSMG Realce crop life cycle and compare its nutritional value with other commonly consumed varieties. Methods: Six treatments were performed: T0 -Control; T1 -Calmar® (soil -100 kg/ha); T2 -Profertil® (foliar -0.5%(v/v)); T3 -Albit® (leaf -0.02%(v/v)); T4 -Calmar® ((100 kg/ha) + Profertil® (0.5%(v/v)); T5 -Calmar® ((100 kg/ha) + Albit® (0.02% (v/v)). Results: The leaf chlorophyll index revealed significant increases for T2, T4 and T5, compared to control. In general, the treatments related to the pods morphology showed significant increases in the length/width ratio. In terms of productivity, significant increases were found with T1, T4 and T5. In the analysis of the nutritional value of dried beans there were significant increases in the contents of fiber in T1, protein in T4 and T5 and carbohydrates for T1, T2 and T3. For mineral composition, there were increases in the phosphorus content of T2, T4 and T5 beans. When the cooked beans were analysed, T4 and T1 produced a greater amount of ash and proteins, as compared to control. Conclusions: The applications of bio-inputs in the bean crop (Phaseolus vulgaris L.) exerted several positive and significant effects, mainly on the CCI, productivity, pod morphology as well as cooked bean nutritional values. It was verified that BRSMG Reakce has the potential to be included in the Portuguese diet.

“…Only calcareous red alga Lithothamnium Philippi sp. is commercially exploited from carbonate sedimentary deposits on the Brazilian coast due to the presence of calcium and magnesium carbonates used to correct soil acidity (Amatussi et al 2020, Mógor et al 2021). Local small-scale production of algae-based biofertilizer is also related.…”

A wide variety of commercial seaweed-based biostimulants is available worldwide for improving plant growth and development for agriculture and gardening purposes. Biostimulant properties are influenced by species, seasonality, preparation methods, and harvest site. This study evaluated the biostimulant properties of the methanolic, hot aqueous and aqueous extracts of three Brazilian macroalgae - Sargassum vulgare C.Agardh (Ochrophyta, Phaeophyceae), Palisada flagellifera (J.Agardh) K.W.Nam (Rhodophyta), and Ulva fasciata Delile (Chlorophyta) - in two different periods (dry and wet seasons) on germination and early development of Lactuca sativa Linnaeus. All three algae increase the total length of lettuce seedlings, with the root length being the primary factor that exhibited growth enhancement. The length of the roots increased by an average of 40% when in contact with the extracts, ranging from 28–55% for P. flagellifera, 37–48% for S. vulgare, and 28–79% for U. fasciata. The extracts promoted resource allocation for elongation of roots, which can aid the plant survival by improving competition for water and nutrients. In general, the biostimulant properties of seaweed extracts varied between harvesting period, since the activity of methanolic and aqueous extracts were influenced by the seasons. Methanolic extracts from the dry season and aqueous extracts from the wet season showed the most biostimulant effect, although overall, the dry season extracts were the most effective. In conclusion, the studied extracts of three Brazilian macroalgae have significant biostimulant properties, which can vary depending on the harvesting period and extract type.

The use of natural bioactive sources to promote plant growth and crop yield gains, such as those obtained from algae, are in evidence as a sustainable agriculture practice. In this sense, recently the calcareous alga Lithothamnium sp. had its bioactive plant growth promoting effect related to the presence of high degree of humification humic acid with pronounced auxin-like effects, while the cyanobacterium Arthrospira platensis (Spirulina plantensis) has the plant growth promoting effect attributed to a pool of bioactive molecules, such as the free L-amino acids and polyamines. To explore the effect of algae sources combinations as plant biostimulants, the aim of this work was to evaluate the effects of foliar application of micronized Lithothamnium (Lm) associated with A. platensis (Ap) dried biomass in onion (Allium cepa) metabolism, growth and yield. For that, adopting an step by step approach three experiments were conducted: (i) foliar application to onion plants grown in pots in greenhouse comparing algae sources alone and combined, (ii) foliar application to onion plants in the field under organic system testing algae sources combinations (first season), and (iii) foliar application in the field comparing doses and frequencies of selected combinations (second season). The association of algae sources promoted growth and biochemical changes, thus pigment contents, total sugars, amino acids and nitrate reductase enzyme activity were improved, increasing the onion yield by two seasons in a nature friendly way.
