ABSTRACT

The total leaf area is an indicator for its nutrient and photosynthetic efficiency of any plant and this can only be calculated either by destructive method through measuring area of individual leaf. Keeping this in view, a regression model has been developed through uni and multivariate correlation analysis, taking total leaf area (m2) as dependent factor (Y) and number of shoots per plant (X1), total shoot girth (cm) (X2), total shoot height (m) (X3) and total number of leaves (X4) as independent factors. The highest value of coefficient of determination (R) to tin tune of 0.9737 was recorded with number of leaves in case of univariate regression equations. The mean deviation between the actual leaf area and calculated leaf area using the equation per plot (for 10 plants) stands only 3.42 per cent. This equation is suitable for bushes having leaves more than 50 in number.
