Agricultural growth modeling based on nonlinear dynamical system

Economic growth modeling for agricultural system is invistigated. The model is describe by a coupled ordinary nonlinear differential equation. The equation can be solved by Runge-Kutta methods. The simulation show that by assuming linear indrustrial growth, the land used tends to constant and the rice production is growth and then become steady. When we consider the technological factor, the rice production can still growth although the land used and total capital reach in a steady state.
