Abstract: Research was carried out at Aleksandras Stulginskis University in 2012. The aim of the study was to estimate the effect of different amino acids concentrations on variations of nitrogen, phosphorous and potassium in aboveground parts of barley under conditions of different moisture content. The soil was Hapli–Endohypogleyic Luvisol. The scheme of the experiment: control, barley sprayed with water, barley sprayed with different concentrations of amino acids 0.5%, 1.0%, 1.5%, 1.5% with microelements B, Mn, Zn, and 2.0%. The study revealed that different concentrations (0.5-2%) of amino acids applied on barley BBCH 21-23 when soil moisture was 14.5% had an essential positive effect on nitrogen content in plants during BBCH 26-29 and BBCH 32-35. During BBCH 39-43 and BBCH 45-49 the essential positive effect was not found. Barley fertilized with different concentrations 0.5-2.0% of the amino acids had essential positive effect of phosphorous on BBCH 26-49 in comparison with the control. Minimal optimal content of the phosphorous was reached on BBCH 26-29 stage due to effect of the amino acids. Application of different concentrations of the amino acids had an essential positive effect on the potassium content in aboveground parts of barley on BBCH 26-43
