MODELLING ON PLANT BIOMASS WITH TIME LAG UNDER THE EFFECT OF TOXIC METAL

Preety Kalra and Pankaj Kumar

Abstract

In this paper, A mathematical model is developed to study the role of delay on plant biomass due to toxic metals and three state variables considered are: concentrations of toxic metal in soil, concentrations of toxic metal in plant and the tree biomass. Hope bifurcation occurred at a critical value of time parameter. Numerical simulation is done using MATLAB.
