Abstract
5 equations for the estimation of cassava leaf area are given for different levels of precision and field use. They are based on various combinations of linear measurements of the leaf taken from samples collected at South Johnstone and Coolum, sites of vastly different climates. There was no difference in accuracy of the equations between sites. The simplest relationship was loge leaf area (cm2) = -7.47 + 2.460 loge main lobe length (mm) giving R2 = 94.5%.
