On simple mathematical models of cultivated plants growth

The paper describes simple "integrated" models of growth of cultivated annual plants received due to experimental data, representing expressions for standard dynamic links of the first order. These models, suitable for the expression of plant growth parameters in an "integrated form", are much simpler than the models applied to modeling of growth processes since the end of the 1960s and developed for the initial data expressed in a "differential" form. The simplicity of the described math models of plant growth simplifies the interpretation of their parameters in relation to the influence of the genotype and external conditions on the plant growth.
