Abstract

The experimental data obtained in stationary field experiments in the conditions of irrigated alluvial meadow-forest soils of the dry subtropics of Azerbaijan (North-Eastern part of the Greater Caucasus) are studied and presented. The use of fertilizer systems (mineral, organic and organic-mineral, i.e. their combined use) had different effects on the accumulation of basic nutrients (NPK) in the aboveground organs (fruits, leaves, stems) of the tomato plant. The efficiency of the influence of different systems of fertilizers under the culture of the tomato is established. Yield and total removal of the potassium effective option the organic - mineral system of organic-mineral system of fertilizers in the norm of the Background—(P90K120) + N60 + manure 12 t/ha; for total removal of phosphorus, organic system of fertilizers in the norm of manure 24 t/ha; and the total removal of nitrogen was efficient Background option—(P90K120) + N120. The overall takeaway was accordingly 272.88 kg/ha potassium; 76.76 kg/ha for phosphorus and 170.56 kg/ha of nitrogen.
