The effects of growth stimulants consist of activating plant physiological processes, which positively affects vegetative and generative growth, increasing the yield and its quality. The aim of the experiment was to study the effect of microbial and amino acid products on the quality of grassland silage; their application in different combinations was an experimental factor. According to the results, the foliar application of the amino acid and microbial products had a statistically significant effect on the chemical composition of silage. In comparison to control, silage produced from plants treated with those growth stimulants contained significantly more total protein in dry matter, while crude fiber content changed only slightly. In addition, due to higher lactic acid content, the quality of silage treated with the stimulants was higher than the quality of control plants. To sum up, the foliar treatment of plants with microorganisms in combination with amino acids resulted in a significant increase in the content of desired components, with a higher nutritional value of the silage.

The Impact

A greenhouse experiment was conducted during the seasons of 2016 – 2017 to compare the impact of foliar amino acids binding (0.5, 1 and 2 g.L-1) and yeast extract ( 2.5, 5 and 10 g.L-1) on certain development and physiological parameters of hot pepper (Capsicum annuum L.). The results cleared that foliar application of amino acid (2 g.L-1) or yeast (10 g.L-1) increased development parameters of hot pepper compared to control in both first and second seasons. Amino acids foliar implementation with (2 g.L-1) gave higher content of anthocyanins, ascorbic acid, lycopene and ß- carotene contents as compared with the control. Also, 10 g.L-1 foliar application of yeast extract showed the best results as compared to control in both first and second seasons. Foliar application of amino acids contents increased phenol and flavonoid contents of hot pepper fruits. Maximum increase was observed at 2 g.L-1 amino acids in both seasons. While 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and lipid peroxidation contents increased with 2 g.L-1 amino acids and 10 g.L-1 yeast foliar application. The HPLC analysis of ethanolic extract of hot pepper fruits has shown fifteen phenolic compounds. Phenolic compounds were increased by increasing the concentration of amino acid and yeast extract foliar application in the both two seasons. In conclusion it is recommended to use amino acid (2 g.L-1) and yeast extract (10 g.L-1) foliar application as they play a key role in productivity , also in protecting the environment as eco-friendly and cost-effective inputs for the farmers.

The aim of the research was to determine changes in the chemical composition in lupin seeds during seed germination in a solution containing selected nitrogen compounds. Blue lupin seeds of the <em>Neptun cultivar</em> were germinated for 3 or 4 days in darkness, at 24°C in 1% solutions containing the following nitrogen compounds: urea, nitric acid, ammonium sulphate, methionine or yeast extract. The control consisted of seeds germinated in water. The presence of all nitrogen sources has resulted in a poorer growth of the sprouts as compared to seeds germinated in water. There was a significant increase in the true protein content as well as a significant decrease in the content of crude ash and alkaloids in the germinated seeds. The seeds germinated for 4 days had significantly higher total protein content and significantly lower content of nitrogen-free extract compounds and oligosaccharides as compared to the seeds germinated for 3 days. A significant influence of the nitrogen source on the concentration of some amino acids was found. Cystine was found to be absent in seeds germinated in the nitric acid solution, while there occurred a twofold increase in the cystine content and a fivefold increase in the methionine content in seeds germinated in the aqueous solution of methionine and an 50% increase in the cystine concentration was observed in seeds germinated in the yeast extract and ammonium sulphate solution. Methionine and cystine were the limiting amino acids in all the samples, accept of seeds germinated in the methionine solution were it was valine. Aqueous solutions of ammonium sulphate and yeast extract were found to have the most advantageous influence on the chemical composition of lupin germination products.

AbstractThe effect of marine calcite, a mixture of ortho- and polysilicic acid as well as orthosilicic acid applied as a foliar spray on the chemical composition of sugar beet leaves in the critical phase of nutrient supply (beginning of July) but also leaves and roots during harvest time in 2015–2016, was studied. The content of silicon in the leaves ranged from 1.24 to 2.36 g kg−1 d.m. at the beginning of July, 3.85–5.34 g kg−1 d.m. during harvest and 2.91–4.20 g kg−1 d.m. in the roots. The foliar application of silicon caused a significant increase in the content of magnesium and calcium in leaves (in July) as compared to the control. The sugar beet consumes approx. 75 kg Si ha−1, which is almost 3.5 times more than P and 20% more than Mg thus proving its importance for its species. About 70% of the silicon taken up by sugar beet is stored in roots and 30% in leaves. The pure sugar yield is most favorably influenced by two- and threefold foliar application of the product containing silicon in the form of orthosilicic acid stabilized with choline, and a threefold mixture of ortho- and polysilicic acid. The increase in the pure sugar yield is not the result of a change in the chemical composition of sugar beet plants, but their more efficient functioning after foliar application of silicon under stress conditions caused by water shortage.

Leonurus Cardiaca

The prospect of creating a new medicine with psychotropic activity is shown as a result of studying the chemical composition and pharmacological activity of modified dry extracts of motherwort (Leonurus cardiaca L.) tincture. The most promising substances were the dry extracts, modified by adding small amounts of arginine, valine, phenylalanine, glycine, lysine, and alanine. A total of 15 main phenolic substances were found in the extracts, and eight of them were identified. There were also 10 hydroxycinnamic acids in these extracts, three of which were identified (chlorogenic, caffeic, and rosmarinic acids). The dominant hydroxycinnamic acids were chlorogenic and caffeic acids. Among flavonoids, catechin, hyperoside, and rutin were identified. It should be noted that the extracts had a significant content of ellagic acid. On the basis of the results of the phytochemical analysis of the extracts, it can be concluded that the composition of phenolic compounds does not differ significantly, and the main differences are related to amino acids, which obviously have an impact on the overall pharmacological effect. The results obtained indicate the presence of anxiolytic activity in the motherwort extracts studied in complex with amino acids. The extracts with glycine, valine, and arginine were more effective in reducing anxiety in animals.
