“…Products containing amino acids are used as stimulants mainly on fruit crops, but research results [23][24][25] indicate that this method is also effective on forage grasses [26,27]. Application of amino acids to agricultural and horticultural crops increases the yield.…”

As plant growth stimulants, Ti and amino acids affect physiological processes of plants, promoting their vegetative and generative development and improving their yield and its quality. An experiment was carried out at the Experimental Station of the University of Agriculture in Krakow on degraded black earth soil formed from loess. Its aim was to determine the effect of two products, one containing amino acids and the other with Ti, on the Poa pratensis yield and its quality. Foliar application of amino acids and Ti, used on their own and together, constituted the main factor of the experiment. It was found that the treatment with both stimulants applied together significantly affected plant parameters. Compared to control, plants treated with those growth stimulants produced higher dry matter yields and contained significantly more phosphorus, potassium, calcium, magnesium, and sodium in dry matter. The highest effect was recorded on plots where combined application of amino acids and Ti was used. Almost as good results were recorded when amino acids were applied on their own. Regarding the cuts, higher effects were noted in the first and second ones than in the third. The growth stimulants used in the present experiment had a positive effect on the chemical composition of Poa pratensis meadow plants. The results indicated that the treatment significantly increased macronutrient content, compared to control plants. The most favourable effects were recorded for plants on the plot with combined application of amino acids and Ti. Similar results were also obtained on plots where only amino acids were used. Regarding the harvests, better results were noted in the first and second ones than in the third. In view of the potential benefits, it would be advisable to extend and update research on the effects of these stimulants on other common varieties of forage grasses.

“…Plants are capable of self-synthesis of amino acids, but this process needs much time and energy. Therefore, the application of these compounds as biostimulants may save energy and improve dynamics of plant development (22). Several studies have reported that the biostimulation action of humic substances on soil mineral availability and acquisition has been attributed to several mechanisms affecting soil properties and plant physiology including: (i) improving soil structure, (ii) increasing cation exchange capacity (CEC) and neutralizing soil pH, (iii) increasing population and activity of beneficial soil microorganisms, (iv) increasing solubility of phosphorous by interfering with Caphosphate precipitation and also by improving the availability of micronutrients by preventing leaching, (v) improving lateral root induction and hair growth due to the auxin-like activity, which triggers plasma membrane H+-ATPase activity, and (vi) stimulating nitrate assimilation through the upregulation of the target enzymes (NR, GDH, and GER) involved in this process (20,25).…”

The experiment was conducted in a greenhouse during 2017 and 2018 growing seasons to evaluate the impact of the shading and various nutrition programs on mitigating heat stress, reducing the use of chemical minerals, improving the reproductive growth and yield of tomato plant. Split-plot within Randomized Complete Block Design (RCBD) with three replications was conducted in this study. Shading factor was allocated in the main plots and the nutrition programs distributed randomly in the subplots. Results indicate that shading resulted in the decrease of daytime temperature by 5.7˚C as an average for both seasons; thus a significant increasing was found in leaf contents of macro nutrients (Nitrogen, Phosphorous, and Potassium), and micro nutrients (Iron, Zinc and Boron), except the Iron content in 2018 growing season. Furthermore, shading improved significantly the reproductive growth and tomato yield. Among the plant nutrition programs, the integrated nutrient management (INM) including the application of organic substances, bio inoculum of AMF and 50% of the recommended dose of chemical fertilizers; lead to the enhancement of nutrients content, reproductive characteristics and plant yield. Generally, combination of both shading and INM showed positive effects on plants nutrient status and persisting balance on tomato flowering growth and fruits yield.

“…Plants are able to take up amino acids and peptides both through the leaves and the root system. In addition, plants are capable of self-synthesis of amino acids, but this process requires much energy (Yakhin et al, 2017;Radkowski, 2018). Amino acids are among the most important organic compounds and play an important biological role as building blocks of proteins, enzymes, nucleic acids, antioxidants, hormones and other components.…”

A two-factor field experiment was carried out in 2018-2020 at the Zawady Agricultural Experimental Station (52°03' N and 22°33' E) belonging to the University of Natural Sciences and Humanities in Siedlce in Poland. Tubers of two edible potato cultivars were investigated, i.e. Oberon and Malaga -factor one; in turn, factor two included variants of herbicide application with biostimulators: 1. control object -without preparations, 2. herbicide clomazone + metribuzin (Avatar 293 ZC), 3. herbicide clomazone + metribuzin and biostimulant PlonoStart, 4. herbicide clomazone + metribuzin and biostimulant Aminoplant, 5. herbicide clomazone + metribuzin and biostimulant Agro-Sorb® Folium. The biostimulators used in the research significantly increased the content of total nitrogen and protein nitrogen in tubers, as well as the share of protein nitrogen in total nitrogen in relation to the tubers collected from the control object. The genetic features of the cultivars also determined the concentration of total nitrogen and protein nitrogen in potato tubers.
