Response surface methodology is used (i) to determine and to quantify the relationship between the response and the levels of quantitative factors and (ii) to obtain optimum combinations of levels of various quantitative factors. Response surface methodology has been extensively used in industrial experimentation but appears to be not so popular in experiments pertaining to agricultural, horticultural and allied sciences. This may be due to the fact that the experimental situations in agricultural sciences are different from those in industrial experiments. Broadly five distinctions viz. (i) time and factor range (ii) factor levels (iii) blocking (iv) accuracy of observations’ (v) shape of response surface are identified. In the present investigation, an attempt has been made to remove these bottlenecks so as to make response surface designs suitable for the agricultural experimentation.

Response surface designs for response optimization and slope estimation when various factors have equispaced levels for both symmetric and asymmetric factorial have been obtained. A new characterization property that minimizes the average variance of the predicted response to a reasonable extent has been introduced. The designs satisfying this property have been termed as modified second order response surface designs. Catalogues of the modified and/or rotatable and group divisible rotatable second order response surface designs with number of factor (v) and number of design points (N) satisfying 3
