Abstract: A large number of response variables were recorded for a long-term rotation experiment at Central Cotton Research Institute, Multan, Pakistan. Short-listing of the response variables and of treatment combination is usually among the objectives of the analysts for such experiments. A visual extension of the Least Significant Difference Test has been proposed in this paper for screening experimental treatments as well as for screening large number of response variables. A graphical layout of unadjusted coefficient of variation has also been introduced in this paper which provides basis for first short listing of response variable. The methods have successfully been applied to the above-mentioned experiment.
