| Abstract | This research was to develop a computer programme and a set-up to determine leaf areas quickly and accurately. The comparison of error and time taken up were made by different techniques, namely computer, square counting and planimeter. Methodology is comprised of (i) application of Visual Basic 6.0 to develop a computer programme to calculate an area out of scanned picture. (ii) comparison between actual triangular and rectangular area (y), and the area determined by computer (x) and planimeter (p), (iii) comparison amongst computer, planimeter and square counting methods to determine areas of leaf and fruit surfaces. Results showed that linear regression could be excellently fitted between y and x. The equation of relationship was y = 0.0086x โ" x0.1293 cm2 (r2 = 0.9999). The relationship between actual rectangular |
