In order to meet the growing market of gerbera, it is necessary to develop studies that maximize its production, especially using organic fertilizer. In order to assess the nutrition and growth of potted gerbera conducted with mineral and organic fertilization, an experiment in a greenhouse was done, located at Western Paraná State University, Brazil. The experimental design was made in randomized blocks, with four replications and five treatments. The treatments were defined according to the source of fertilization, mineral (NPK) or organic. The organic fertilization were obtained by diluting in water four organic compost of poultry slaughter waste, obtained from in the composting process, in order to adjust electrical conductivity. The solution of the compost was used as organic fertigation, making the organic treatments. The liquid organic fertilizer, as well as irrigation of mineral treatment, was performed manually once a day. At the end of vegetative and reproductive periods, the levels of N, P, K, Ca, Mg and Fe were quantified in the plant tissue. At the same time, biometric parameters were assessed (number of leaves, plant diameter, leaf area, dry matter of aerial parts, number of heads, inflorescence dry matter, stem height, head diameter and diameter stem). The liquid organic fertilizers, obtained by composting procession of poultry slaughter waste, can be used as alternative source for potted gerbera nutrition, since they provide better or higher culture growth than the mineral fertilizer.
