Observational variables in this studywere root volume (cm3), plant dry weight (g), flower/crop diameter (cm), and flower weightper/plant (g). The results showed that the provision of duck droppings had no significant effecton observational variables such as root volume, plant dry weight, flower diameter, and flowerweight.Key words : duck droppings, peat soil, flower cabbage plants
