Abstract

In this paper, the Richards function in the form y(t) = A(I +be−kt)1/(1‐m) was used to precisely analyze plant growth. The first, second and third derivative formulae of the above function were given. A new parameter, G12= f(m) was derived, enabling the calculation of the coordinates of critical points which mark the principal growth phases. The coefficients of Richards model describing the dry matter accumulation in buckwheat 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 buckwheat plants by means of Richards function was confirmed statistically.
