Abstract: The article presents data on the influence of fertilizer systems and their aftereffect on the yield and quality of grain of spring wheat variety MIS. The aim of the study is to establish effective and ecologically safe doses and combinations of litter manure and mineral fertilizers and their impact on the yield and quality of plant products in the cultivation of spring wheat. The studies were carried out in 2007–2008 and in 2014–2015 on two fields under the conditions of long-term field experience of the Geographical network according to the generally accepted method. In the period 1978–2008 years of experience in the crops field rotation experienced the effect of organic and mineral fertilizers, and in 2009 their aftereffect on the backdrop of the spring fertilizing with nitrogen in the dose of N45. It was found that the yield of spring wheat with long-term use of or- ganic and mineral fertilizers (2007–2008) was significantly higher than on the nitrogen background, without the introduction of phosphorus-potassium and organic fertilizers (2014–2015). With one-sided application of mineral fertilizer and manure increase compared to control was 8.4 and 11.4 c/ha. Application of organic-mineral systems increased yields of up to 106 %. The yield of spring wheat, which was cultivated by the aftereffect of organic and mineral fertilizers on the background of nitrogen fertilizing at a dose of 45 kg, decreased by about 2 times. The combined use of organic and mineral fertilizers also increased the protein content and weight of 1000 grains. In the years with the introduction of mineral and organic fertilizers, the grain size depended only on mineral fertilizers, in the years without fertilizers, potassium mineral fertilizers and manure contributed to the increase in the mass of 1000 grains. In both cases, nitrogen fertilizers contributed to the increase in the con- tent of crude protein in the grain of spring wheat. The correlation between the weight of 1000 grains and the yield of spring wheat is established.
