      abstract = {The use of response surface designs in preference to  factorial designs in agriculture has become widely  discussed and recommended. This paper simulates data for  comparable response surface and factorial designs and uses  this to demonstrate the similarities between the designs  and their analyses and at the same time to point out some  of the customary differences in their analyses. More  particularly, it aims to show: (a) that for any design a  reduction in the number of plots sown reduces the  reliability of the results, and (b) that both a response  surface design and a factorial design allow the calculation  of estimated equations of response surfaces.},
