AB  - In every day life resources are lost because of human inability to transform most of our typical life problems into statistical or mathematical concept. Over the years agriculturist have lost so much in the purchase of different types of fertilizers and yet cannot combine them to obtain optimal yield of their crops. A quadratic programming model for this problem is here established using the concept of response surface methodology. Investigations shows that the model suit the Nigerian situation since it prevents sub-optimality some times obtained by farmers which may be caused by wrong combination of fertilizers possibly based on tradition and customs.
