Abstract

    The designs for mixture experiments have been extensively used in agricultural/ industrial experiments. Some of the situations in which these designs could be advantageously used are: split application of fertilizers, intercropping experiments where the interest of experimenter is to find best crop mixtures, sensory evaluation experiments for making the agricultural and animal products, preparation of fertilizers, insecticides/ pesticides mixtures for optimum response, feeding trials in animal nutritional experiments. Mixture experiments can be used in with unrestricted region, with restricted region having upper and/or lower bounds, with process variable(s).
