Modified Inverse Polynomial and Ordinary Polynomial as a response Surface Model: A case study of Nitrogen, Phosphate, and Potassium level on the yield of Maize

Abstract

A statistical modeling method is presented for yield of maize with fertilizer response using response surface methodology. It was shown that careful consideration of the class of response surface model (RSM), using domain knowledge give models which are of order two magnitudes as good as the more conventional polynomial models. This study shows that the modified inverse polynomial performs better in studying the response of the yield of maize as against the ordinary polynomial.
