Effect of Amino Acids and Effective Microorganisms on Meadow Silage Chemical Composition

anglais. 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.
