Abstract
Bolotova T.M., Makarov V.I. Analytical equations of production functions in crop growing as a consequence of the laws of plants physiology. The subject of the paper is the definition of the analytical form of production functions in plant growing on the basis of experimental data. The purpose of the article is to determine the production functions of winter wheat "Mironovskaya 808" using the least squares method on the basis of experimental data [4]. On a concrete example, to demonstrate the fact that, as a rule, the recommendations on the technology of making the composition of NPK fertilizers are economically unjustified. The method of the study is mathematical interpretation of the laws of plants physiological development is given. These laws are the follows: the law of minimal limiting factor, the law of Liebig’s minimum, and the law of the maximum limiting factor, the law of Shelford's tolerance. The result of the work is the established analytical equations for the production functions made possible to determine the optimal nutrition standards for the plants. It has been shown that, as a rule, the existing recommendations as for the technologies of introducing the composition of NPK fertilizers are economically unjustified. Key words: law of Liebig’s minimum, law of Shelford’s tolerance, production functions, least squares method, regression function, surfaces of yield function level.
