“…Due to the fact that maize is widely cultivated as a second-season crop, when climatic conditions are not always favorable, it is necessary to adopt strategies to minimize the effects of environmental stresses, since maize seedlings with larger leaf area have larger contact surface for light absorption and, consequently, their photosynthetic activity will be potentiated, resulting in greater metabolic activity, and greater production and translocation of carbohydrates, providing greater resistance to environmental stresses (Kolling et al, 2016).…”

Biostimulants are used as a strategy to minimize the effects of climatic adversities by allowing the seedlings to express more strongly their metabolic capacity and to have a greater root system development. The objective was to evaluate the effect of seed treatment with different doses of a biostimulant composed of Ascophyllum nodosum on the agronomic performance of maize seedlings. The experiment was carried out in a randomized block design with five treatments and four replicates, using five doses of the biostimulant, 0,0; 0.25; 0.50; 0.75; and 1.00 liter of product per 100 kg of seeds. The following were evaluated: vigor, fresh mass of roots and shoots, dry mass of roots and shoots, root length, shoot height, and leaf area. The data were submitted to ANOVA and regression analysis to verify the behavior of the characteristics as a function of the biostimulant doses. In the treatment of seeds, these doses provided increases in vigor, shoot height, fresh and dry mass of shoots, and leaf area. The biostimulant derived from the Ascophyllum nodosum extract showed potential use in the treatment of maize seeds, with the doses of 0.50 and 0.75 liters per 100 kg seeds being the most promising for the initial development of maize seedlings.

“…Biostimulants are a mixture of two or more plant regulators or plant regulators with other biochemical substances, such as amino acids, vitamins and nutrients (Castro & Vieira, 2001;Kolling et al, 2016). The use of biostimulant may be an alternative to assist plants in overcoming abiotic stresses, as they act as hormonal and nutritional enhancement and stimulate root system development (Oliveira et al, 2016;Galindo et al, 2019).…”

“…Still, Oliveira et al (2017) concluded that the use of biostimulants in seed and leaf treatment provided better development of cackrey plants. It is noteworthy that the response of crops to treatment with biostimulants is dependent on environmental condition and nutrient availability (Binsfeld et al, 2014;Kolling et al, 2016). However, the increased use of biofertilizers is closely linked to advances in growing technologies and the promotion of higher productivity with stability, aiming at mitigating the limiting factors of production such as weather conditions, pests and diseases.…”

“…One possibility of improving the efficiency of nutrient utilization in agricultural crops is the application of biostimulants (Carvalho & Zabot, 2012;Domingos et al, 2015). Biostimulants are a mixture of growth regulators isolated and / or combined with other compounds, such as amino acids, nutrients, vitamins and others, which seek to provide nutrition and help in overcoming stress (Castro & Vieira, 2001; Kolling et al, 2016). These compounds modify protein expression acting on defense mechanisms, enzyme activation and plant nutrition and are generally provided considering the absorption route via leaf (Almeida et al, 2009;Olsen et al, 2016).…”

The supply of glutamic acid-based biostimulants may represent an innovative technology to increase oat grain yield and quality. The objective of this study is to measure the effect of different biostimulants based on concentrations of glutamic acid and nutrients and their application on indicators of productivity and industrial and chemical quality of oat grains. The study was conducted in 2016 and 2017 in a randomized block design with four replications, considering 10 combinations of treatments for different application conditions and types of glutamic acid-based biostimulants, which were: 1. Control; 2. Zinplex (seed) + Biomol (grain filling); 3. Zinplex (seed) + Glutamin Extra (grain filling); 4. Zinplex (seed) + Biomol (thinning); 5. Glutamin Extra (1st fungicide application) + Glutamin Extra (2nd fungicide application); 6. Biomol (1st fungicide application) + Biomol (2nd fungicide application); 7. Zinplex (seed) + Vorax (grain filling); 8. Vorax (1st fungicide application) + Vorax (2nd fungicide application); 9. Biomol (thinning) + Vorax (grain filling) and 10. Biomol (thinning) + Glutamin Extra (grain filling). The foliar application of biostimulants with the presence of glutamic acid and nutrients may have positive effects on variables related to productivity and industrial and chemical quality of oat grains, however, depending on the agricultural year conditions. The application of Glutamin Extra in the 1st and 2nd fungicide application shows the best results in the vast majority of grain yield and quality variables, but the costs involving only biostimulants do not guarantee economic viability.

“…Thus, in the search for a better seed performance in the field, technologies associated with seed treatment have been developed in order to provide a higher vigor to seedlings (Kolling et al, 2016;Cunha et al, 2015;Abrecht et al, 2014;Brzezinski et al, 2015). An alternative that has been widely studied to improve the performance of seeds and plants in the field is the use of amino acids in different crops through different forms of application in order to promote plant growth and improve the quality of the harvested products (Ludwig et al, 2011;Bettoni et al, 2013;Hammad and Ali, 2014;Wang et al, 2014;Mondal et al, 2015).…”

The aim of this study was to assess the effect of seed treatment at different levels of physiological quality with amino acids on the performance of seeds and plants in the field. The experimental design was a randomized complete block design with four replications involving a combination of two factors. Factor A consisted of seed lots of three levels of physiological quality (high, intermediate, and low) and factor B consisted of five doses of a commercial product based on amino acids used in seed treatment.Seeds of different levels of physiological quality were treated with a commercial product (C.P.) at doses of 0, 200, 400, 600, and 800 mL C.P. 100 kg−1 of seeds. After seed treatment, the physiological performance was assessed in the laboratory and then the seeds were sowed in the field aiming at assessing plant performance, yield components, and productivity. Seed treatment with amino acids does not promote the physiological performance of seeds and plants in the field. The productivity of isolated soybean plants from seed lots of a high physiological quality is 15% higher than that of plants from seed lots of a low physiological quality.
