“…Despite the establishment of the European Biostimulants Industry Council (EBIC) (formed to develop the legal regulations concerning the registration of biostimulants according to the specificity of their action), the registration of preparations is still based on the legal regulations set for fertilizers and plant protection agents (Traon et al, 2014 ; Chojnacka, 2015 ; Du Jardin, 2015 ).…”

Improvement of crop cultivation technologies is focused on increasing crop productivity and improving yield quality, and at the same time on minimizing risks posed to the natural environment. The use of biostimulants contributes to the increase in the productivity of plants, especially under their exposure to stress induced by negative environmental stimuli. A field experiment was conducted in three growing seasons (2014–2016). Seeds of soybean of the Atlanta cultivar were sown in the third decade of April. Two synthetic biostimulants were used in the growing period in the form of single (stage BBCH 13-15) or double (stage BBCH 13-15, BBCH 61) spraying: Atonik (in concentrations of 0.1 and 0.2%) and Tytanit (in concentrations of 0.07 and 0.13%). Atonik, the first tested biostimulant, contained three phenolic compounds: sodium p-nitrophenolate, sodium o-nitrophenolate, and sodium 5-nitroguaiacolate. The Tytanit preparation contained a titanium complex, magnesium oxide, and sulfur (VI) oxide. This work presents a complex study addressing the action of the biostimulants Atonik and Tytanit and demonstrates their effect on the physiological traits, plant productivity, and seed yield quality of Glycine max L. The conducted experiment proved that the biostimulant type, as well as the number of its applications and its concentration, modified the biometric traits, crop productivity, as well as yield quality and the nutraceutical and antioxidative potential of soybean seeds. It was also found that by positively affecting plant growth and seed yield, the Atonik and Tytanit also resulted biostimulants decreased the protein and lipid contents in seeds. A double application of these preparations in their higher concentrations had a more positive impact on soybean seed number and soybean seed yield. The use of both Atonik and Tytanit resulted also in an increased antioxidative activity of soybean seeds. The greatest increase in this activity was observed after the application of the Tytanit preparation. Dietary fiber fraction analysis demonstrated an increase in the acid-detergent fiber, lignin, and cellulose contents in soybean seeds as a result of biostimulant application; however, the increase was greater upon the use of Tytanit. In contrast, the neutral-detergent fiber, cellulose, and hemicellulose contents were observed to decrease in all analyzed combinations of crops treated with the tested preparations.

“…Even though biostimulants offer novel possibilities and although their use in agriculture is in many cases deemed beneficial for improved crop yielding, the exact mechanism of their action still remains unknown, which is indicated by the presented results concerning the contents of dietary fiber in bean seeds [86,87], because the effect of biostimulants on plants is not only a consequence of their direct role in metabolism regulation, but also of their multi-faceted action. The most important, however, is the fact that-unlike hormones-biostimulants improve metabolic processes in plants without modifying their natural pathways [87,88].…”

Towards Sustainable Agriculture—Agronomic and Economic Effects of Biostimulant Use in Common Bean Cultivation

et al. 2019

Today, one of the greatest challenges faced by the agriculture industry is the development of sustainable and environmentally-friendly systems to meet nutritional demands of the continuously growing global population. A number of research studies have recently been undertaken with the aim to indicate types of parameters used in plant production that would be able to improve plant growth as well as the effectiveness and quality of yield, and to help plants cope with environmental stress. The aim of this study was to verify a hypothesis that the implementation of a sustainable agricultural technology, based on the use of synthetic biostimulants, will allow not only increasing crop yield and quality but also improving the cost-effectiveness of common bean cultivation. The field experiment was conducted in three growing seasons (2016–2018). In the growing season, the plants were treated with Atonik and Tytanit biostimulants in the form of single or double spraying. We determinated biometric traits, seed yield, seed number, and 1000-seed weight. Further analyses included contents of nutraceutical potential. The economic effect of using biostimulants was also calculated. The results of our experiment allowed verifying a hypothesis that the implementation of a sustainable agricultural technology based on the use of synthetic preparations was an effective method to increase plant productivity and, consequently, economic profits to farmers.

Biostimulants and possibilities of their usage in grassland

2019

View full text Add to dashboard Cite

Currently, in addition to a wide range of lawn fertilizers on the market, there are new biological products available called biostimulants, fostering plant growth and development. They are based on substances of natural origin, containing plant extracts, hormones or humic substances. Biostimulants exert a positive impact on grass metabolism, stimulating life processes and reducing negative effects of pathogen infestation and adverse environmental conditions like drought, salinity or temperature fluctuations. Disparities and the lack of a uniform position to recognize biostimulants as a strictly specified group pose many problems in legislative issues, with erroneous terminology used in relation to different groups of bioactive substances applied to crops. All this creates a situation when products of untested and unstable effects are placed on the market, even if they sometimes do not have any impact on plant growth despite the claims of the producer. Growth‐promoting potential of biostimulants is very significant, and previous research has shown real benefits of their use. Increasing environmental awareness and environmental regulations is an additional factor positively affecting the development of such products. However, there is still a lack of studies that would fully characterize the reaction of plant metabolic processes to biostimulants. The aim of the study was to review current knowledge of plant biostimulant usage in grassland.
