A general method of construction of efficient row-column designs with two rows has been developed. Lower bounds to A- and D- efficiencies of the designs obtained through the proposed method of construction for 3 ≤ v ≤ 10, v ≤ b ≤ v(v-1)/2, 11 ≤ v ≤ 25, b = v and (v, b) = (11, 13), (12, 14), (13, 14) and (13, 15) where v is the number of treatments and b is the number of columns have been computed and compared with those of best available designs in the above parametric range in the literature under a fixed effects model. The lower bounds to A- and D- efficiencies of the designs obtained have also been compared with those of best available designs in the literature under a mixed effects model (considering column effects as random). Robustness aspects of optimal/efficient designs has been investigated under a mixed effects model for different values of ρ (a function of inter and intra column variances). Several designs have been obtained that are more efficient under mixed effects model as compared to the best available designs. A computer programme using C# programming language with ASP.NET platform has been developed for generating efficient row-column designs in two rows in the above restricted parametric range. The A- and D- efficiencies of the designs are also reported.
