“…The value of macroalgae as fertilizers or biostimulants of plant growth results from the content of macroelements, trace elements, and other metabolites. These compounds are necessary for the plants growth and enhancement . Therefore, it can be assumed that produced from macroalgae extract will be a concentrated form of biologically active compounds.…”

“…In the case of algal extracts, generally they stimulate the seeds germination, but it depends on many factors such as algae species, extraction method, concentration and chemical composition of extract, method of application, plant species, etc. The range of concentrations of algal extracts used in germinations tests is very wide, from very low, for example, 0.2, 0.4, and 1% for tomato and 0.2, 0.4, 0.6, 0.8, and 1% for mung bean , to much higher, for example, 2.5, 5, 7.5, 10, 12.5, and 15% for soybean ; 5, 10, 20, 30, 40, 50, and 100% for cowpea ; 20, 40, 60 and 100% for soybean . In the literature it was shown that seeds treated with lower concentrations of algal extracts exhibited higher germination rates and germination percentage, while the higher extracts concentrations inhibited the germination, for example, above 40% for cowpea , above 0.01% for tomato and lettuce .…”

“…Marine algae are rich in potassium (K) and contain many growth promoters such as auxins, gibberellins, and cytokinins. Moreover, in the literature it was shown that extracts produced from green macroalgae increased the germination percentage of soybean seeds, growth and yield, nutrient uptake, biochemical parameters (carbohydrates, proteins, phenols), and pigment content (chlorophyll, carotenoids), for example, Cladophora glomerata , Ulva fenestrata , Codium fragile , and Enteromorpha intestinalis . One of the weaknesses of seaweeds is their capacity to accumulate several toxic metals, such as arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), etc.…”

In the present study, the effect of the static and alternating magnetic field applied individually and in combination with an algal extract on the germination of soybean seeds (Glycine max (L.) Merrill) and chlorophyll content was examined. The exposure time of seeds to the static magnetic field was 3, 6, and 12 min, whereas to the alternating magnetic field was 1, 2.5, and 5 min. The static magnetic field was obtained by means of a permanent magnets system while the alternating magnetic field by means of magnetic coils. Algal extract was produced from a freshwater macroalga—Cladophora glomerata using ultrasound homogenizer. In the germination tests, 10% extract was applied to the paper substrate before sowing. This is the first study that compares the germination of soybean seeds exposed to the static and alternating magnetic field. The best effect on the germination and chlorophyll content in seedlings had synergistic action of the static magnetic field on seeds for 3 min applied together with the extract and alternating magnetic field used for 2.5 min. It is not possible to clearly state which magnetic field better stimulated the germination of seeds, but the chlorophyll content in seedlings was much higher for alternating magnetic field.

“…This is in accordance with literature data, which confirm the positive effect of algal extracts on the growth and performance of soybeans. Mathur et al [58] tested the effect of green seaweed -Enteromorpha intestinalis derived liquid fertilizer as a biostimulant for Glycine max (L.) Merr. It was found that 60% of the algal extract (among tested concentrations -20, 40, 60 and 100% and control groups -water and chemical fertilizer) positively influenced seed germination, root and shoot length, the content of carbohydrates, proteins and pigments.…”

Influence of the Static Magnetic Field and Algal Extract on the Germination of Soybean Seeds

et al. 2019

This study examines the effect of a separate static magnetic field (SMF) and algal extract and their synergistic effect on soybean seeds germination. To our knowledge, this is the first time these kinds of factors were used for the biostimulation of soybean seeds germination. Soybean – Glycine max (L.) Merrill variety ‘Merlin’ was used in the present study. The exposure of seeds to the magnetic field was applied for 3, 6 and 12 min. The algal extract, produced from a freshwater green macroalga – Cladophora glomerata using an ultrasonic homogenizer, was used directly to the paper substrate at a dose of 10%. The highest germination ability of soybean seeds was observed in a group, where the magnetic field (12 min.) was used together with 10% of algal extract. However, it was very low – only 21%, which may have resulted from the seed dormancy. Future experiments on soybean seeds are required to confirm the stimulation effect of the magnetic field (various induction values) and algal extract on seeds germination.

“…Many studies pertaining to plant growth-promoting effects of seaweed have been reported by Shimaa et al (2016). In fact, the plant growth-promoting seaweed substances in Arabidopsis influence the biosynthetic pathways of phytohormones in plants (Jithesh et al, 2012) and a rich amount of auxin, gibberellins, cytokinins and antibiotics boost the growth and yield of soyabean (Mathur et al, 2015). Pacholczaket al (2016) have proven that in nine bark stem cuttings (Physocarpusopulifolius), the seaweed was the novel source of antioxidants and plant hormones osmoprotectants, plant nutrients and also bioactive metabolites of pharmaceutical and industrial significance.…”

The monocropping of rice in the Deltaic zone deteriorates soil health and crop productivity. Seaweeds are marine resources easily available at negligible cost and also rich in bioactive compounds. A field experiment was conducted at Cauvery Delta zone of Tamil Nadu during summer season2021 to evaluate the bio-efficacy of Seaweed extract on growth, yield, and soil properties of rice, Oryza sativa var. ADT53. The experiment was framed in RBD comprising of 12 treatments viz., soil application of Seaweed extract(SWE) @ 12.5kg/ha,25kg/ha, 37.5kg/ha , foliar spraying of SWE gel & liquid @ 0.5% twice at tillering and panicle initiation stages, a combination of soil application and foliar spray and fertilizer alone. Experimental findings revealed that the soil application of SWE @ 12.5kg/ha along with a foliar spray of seaweed liquid recorded higher plant height (121.1cm),dry matter production (11390kg/ha),yield attributes viz., number of grains per panicle (166), panicle length (21.8 cm), thousand grain weight (14.7g), number of productive tillers per m2 (275), grain yield (5612 kg/ha)and straw yield (7829 kg/ha). However, The soil application of SWE @ 25kg/ha recorded higher soil available nutrients viz.,N(260 kg/ha);P(42kg/ha); K(170kg/ha);Ca(27.7meq/100g); Mg(5.5meq/100g);S(18.2mg/kg);Zn (1.17ppm); Fe (33.82ppm); Cu(1.61ppm);Mn(18.97ppm).The study will help sustain rice productivity and soil fertility in the deltaic zone of Tamil Nadu. The soil application of seaweed extract @ 12.5kg/ha along with foliar spraying (0.5% twice) could be a promising option in the rice ecosystem.
