Main Article Content
Abstract
In this paper the Richards’s function in the form was used to precisely analyze Fast plant growth. The first, second and third derivative formulae of above function were given. A new parameter
was derived, enabling the calculation of the coordinates of critical points which mark the principal growth phases. The coefficients of Richards’s function describing the dry matter accumulation in Fast plants were numerically calculated. The growth curve, growth rate curve and the growth acceleration curve were also drawn. A high usefulness of approximation of the growth process of Fast plants by means of Richards’s function was confirmed statistically. This will result in better agricultural productivity and this is the benefit of mathematical applications to agriculture.
