AB  - The introduction of ornamental crops to the Comarca Lagunera is a great market opportunity for producers of flowers, just as it is the case of <i>Caladium bicolor</i> which is exported to Europe, USA, Caribbean islands and Africa. The use of organic products derived from cattle manure for fertilization, improves physical soil conditions and provides significant amount of nutrients to plants and reduce production costs. Therefore, the objective of this study was to quantify the growth of tubercle and root of the ornamental plant <i>Caladium bicolor</i> by applying organic fertilizer (OF) extracted from cattle manure. The experimental design was completely randomized and the treatments were three doses of OF: 0 control, 4, y 8 mL/L. The variables were measured with image analysis, and OF was characterized with infrared spectrophotometry. With the data collected was performed ANOVA and treatment means were compared with Tukey test (P≤0.05). Treatment with 8 mL/L of OF, compared to 4 and 0 mL/L, showed greater tubercle growth (126.61%) with respect to its initial size and root surface (37.485 mm<sup>2</sup>) in the period from august to December 2012. Under the experimental conditions described, it includes that the extracted OF bovine manure induces a high adsorption capacity due to its carboxyls, hydroxyls, amines, amides and methyl, which together increase the growth of the tubercle and root in <i>C. bicolor</i>.
