Relative efficiency (e%) in relation to the most efficient treatment (intensity of 20 %/sample unit 10 m × 25 m), according to the different sampling procedures in each sampling intensity and shape of the plot (m × m) tested, for the 15 treatments selected according to the maximum sampling error admitted (E%). Note: 15 and 20 correspond to intensities of 15 and 20 %, respectively
