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