On Absheron gray-brown soils, studies were carried out using various doses of copper microelement against the background of macrofertilizers on the productivity and quality of innab fruits. The results of laboratory analyses showed that Absheron's gray-brown soils are poorly provided with forms of nitrogen, phosphorus and copper microelement and potassium medium. The microelement copper was carried out under the innab culture against a background N₁₀₀P₄₀K₇₀ in 3 doses. The results of the studies showed that the highest productivity increase (3.2 s/ha or 11.2%) and fruit quality (vitamin "C" 635mg/%, sugar 32.5%, acidity 0.57% and microelement content: Cu-28.3-Zn-30.5.0mg/kg,) the innab plant is observed in the version with copper application at the rate of 2.0 kg per ha.
