Abstract:
This paper concerns the application of some theories surrounding the exploration of response surface using inverse polynomial models which include the construction of response surface designs, the methods of parameter estimation by the iterative methods of non-linear least square and the method of optimization such as the Fletcher-Reeves conjugate Gradient method. We verify the adequacy of the model using a well analysed experimental data on maize-bush beans intercrop to determine the appropriate plant densities which yield optimum responses. This new approach compares favourably for a general surface (K=k and P=p factors and levels respectively)

Keywords: response surface methodology (RSM), conjugate gradient method, inverse polynomial, land equivalent ratio (LER)
