Indicators of the Relationship Between the Chemical Composition of Plant and Harvest Potatoes

The authors carried out long-term research on the effect of mineral fertilizers “Gala” potato variety in Pavlodar region. relationship was established between nitrogen, phosphorus and potassium chemical composition plant certain phases growth development. Various biochemical processes occur soil plants every second. productivity (y) depends how take place proceed, since it is a function (x) leaves: y = f x. theoretical foundations diagnostics are based role nutrients formation crop, starting from early stages According to Yu. I. Ermokhin, theory this provides information needs plants, practice these must be satisfied. field experiments with obtain sought-for connections low optimal content ratio plant, which confirmed by high correlation coefficients (r 0.79-0.97). If nitrogen higher than 4.64% 7-leaf phase 4.16% flowering phase, then nature ovary takes different meaning equation described quadratic parabola form.
