Abstract: The winter wheat cv. 'Širvinta-1' was grown at the Aleksandras Stulginskis University's Experimental Station during the period 2006.2009. The soil of the experimental site is medium textured loamy carbonaceous leached soil - Cal(ca)ric Epihypogleyic Luvisol. Winter wheat additionally foliar - fertilized with liquid amide nitrogen fertilizer at a rate of 10 kg ha-1 N containing different concentrations of amino acids ( at milk maturity stage, produced a grain yield increase of t ha-1. Amino acids were also found to improve winter wheat yield quality indicators. Under the effect of amino acids, grain protein content increased by percentage points, sedimentation volume by 2.5 ml, wet gluten values by 0.7 . 1.3 percentage units and falling number by 24 s. Winter wheat grain yield were found to statistically significantly correlate with amino acid concentration in liquid amide nitrogen fertilizer (n= 0.95*, respectively). The polynomial correlation regression analysis indicated that when winter wheat had been applied with amino acids fertilizers at milk maturity stage, sedimentation value very strongly correlated with amino acids concentration in fertilizer and gluten content
