A field design using a decagonal geometric shape is described which enables twenty small plots, each 0.08 ha in size, to be evaluated under communal grazing condilions. The decagonal design was compared with a conventional design using botanical composition and plant density as discriminating parameters. The results showed that communal grazing in the decagonal design gave similar botanical composition and plant density as the conventional design. Since less materials per treatment were used in the decagonal design, it offers a means of minimizing costs in preliminary screening experiments. However, since animal production cannot be monitored under communal grazing the most successful treatments would have to be further evaluated using the conventional approach.
