An indirect method of leaf area measurement for Rizor sugar beet cultivar was tested. Leaves were sampled during two growing seasons in a Randomised Complete Block Design experiment. For 2002 samplings, leaf area [cm2] was linearly correlated with maximum leaf width [cm] using all leaf samples (r2 = 0.83, p < 0.001) or using the means of the 8 sampling occasions (r2 = 0.97, p < 0.001). Correlations between leaf area and leaf mid vein length [cm] were weaker (r2 = 0.75, p < 0.001 and r2 = 0.93, p < 0. 001, respectively). For 2003 samplings, the area estimated by the equations was highly correlated to the measured leaf area.

Additional key words: leaf area; leaf length; leaf width; non destructive methods
