Measurement of the Effects of Liquid Fertilizers at the Different Levels on Duckweed (Lemna Minor L.) Growth Using Image Analysis Technique

ABSTRACT

This study aims the measurement of the effects of liquid fertilizers at different levels on the growth of duckweed (Lemna minor) and to investigate the relationship between the weight and surface area covered by duckweed via image analysis technique. A linear correlation was found between these values (R²=0.972). The equation is indicated as Y=5.10975+0.199898X where X is the surface area covered by duckweed (mm) and Y is the duckweed weight (mg). It can be emphasized that the results calculated by image analysis technique were at par with the results obtained by weighing.
