In course of the research there was studied the influence of different doses of fertilizers, aftereffect of manure and green manure with straw on yield and grain quality of barley (Hordeum vulgare). The research was realized in the conditions of south region (Gomel) of the Republic of Belarus in 2009-2010 on sod-podzolic loose sandy loam soil, underlain from depth of 50-70 cm with pulverescent sandy moraine loam. The agrochemical indicators of arable horizon were: humus content – 1.66%, pH (in KCl) – 5.4, phosphorous and potassium content accordingly 219-252 mg/kg of soil. Under the preceding crop potato (Solanum tuberosum) in the autumn 2007 and 2008 according to the experiment scheme covering manure from calculation 64.4 t/ha and straw of winter rye (Secale cereale) (6.0 t/ha) has been brought. As a result of realized research it was revealed that for cultivation of barley on sod-podzolic pithy sandy loam soil the highest efficiency of mineral fertilizers was after application of N120P60K140 next year following the application of manure. It has ensured the maximum productivity of grain – 50.4 c/ha. Yield of crude protein on this variant has made 5.8 c/ha.
