ABSTRACT

This study carried out to estimate the leaf area using the regression analysis based on the measured leaf length and leaf width of tomato grown in greenhouse. The coefficient of determination of fitted the linear regression to the values of leaf length multiple by leaf width was much higher than the value of the fitted to a single independent value. When planting density is increased the index (the value of leaf length divided leaf width) increase, especially leaf length was higher than leaf width of tomato plant. Although estimated a single leaf area with increase leaf position showed a large residual between measured and fitted values, a tendency suggest that few measured leaf length was long width wide leaf width. In order to make a good regression model a research would observed the elongation of the leaf width and length, season, cultivar (cherry, medium and large tomato group) for stabilizing the coefficient of the regression.

Additional key words: Tomato, Leaf area, Non destructive measurement, Plant growth and development
