Plants may be considered useful, or not, depending on the way they are characterized by humans. Some go from weed to food, cosmetic or medicinal, making economically interesting the cultivation. Bidens pilosa L. (hairy beggartick) is a specie in this context, which was submitted to an agronomic test to evaluate its productivity (fresh mass and dry mass) and flavonoid content. It was cultivated with different levels of organic fertilization (tanned bovine manure - 50 t ha-1) and shading. The experimental design was a randomized block with 3 replications, in a factorial scheme of 22, consisting of 4 treatments (1. With fertilization + shading 0%, 2. With fertilization + shading 50%, 3. Without fertilization + shading 50% and 4. Without fertilization + shading 0%). The results showed that the cultivation using organic fertilizer, in the full sun produced 63% more vegetal drug than the treatments without organic fertilization, using or not shading. In relation to the flavonoid content, statistical equality among all treatments was found, but the highest numerical result (0.096% m/m) for this parameter was obtained without fertilization and without light restriction and the lowest (0.058% m/m), with fertilization in the full sun.
