The analysis of role of microelements in the content of liquid nitric fertilizers on development of yield and quality of grain of spring wheat Rassvet is given. Dates of taken experiments show that using of the forms of nitric fertilizers influences on the content in grain albumen, aminoacids, quality of glutein. It stresses that the using of scientific substantiated methods of itemized bringing of liquid nitric fertilizers gives the biggest effect in the main periods of formation of harvest. On the basis of the research in 2006-2007 on sod-podzolic light-loam soil with high agrochemical indicators, high provision by copper and low provision by manganese, it is established, that application of liquid nitric fertilizers with additives of microelements (copper and manganese) or microelements and regulators of growth of plants gidrogumat and epin in doses N90 and N6O+30 promotes improvement of quality of grain of spring wheat of Rassvet variety in comparison with use of standard liquid nitrogen fertilizers. Variants with entering N90 kg/ha in the form of liquid nitrogen fertilizes with Cu1, and a regulator of growth of plants gidrogumat, liquid nitrogen fertilizers with epin2 and liquid nitrogen fertilizers with Cu1-2 have appeared the best on biological value of protein. At fractional entering of nitrogen (N6О+30) the most valuable protein was in variants with entering liquid nitrogen fertilizers with Cu2, liquid nitrogen fertilizers with Cu1 and a regulator of growth of plants gidrogumat and liquid nitrogen fertilizers with Cu1+Mn1 + growth regulator epin1
