Abstract
Gerbera can be grown as a cut flower or in pots. However, there is little information on nutrition and fertilization, especially related to phosphorus and the use of organic matter in pots. This study aimed to evaluate the growth and production of potted gerbera under doses of phosphorus and the use of cattle manure. The experiment was carried out in pots, under greenhouse conditions. A randomized block experimental design was used in a 5 x 2 factorial scheme with 4 replications, totaling 40 experimental units. The treatments consisted of 5 P rates: 0, 20, 40, 60 and 80 mg dm-3 P, as triple superphosphate powder and use, or not, of cattle manure. Phosphate fertilization and cattle manure in soil with low P contents did not influence the growth and production of potted gerbera. Phosphorus rates improve the nutritional status of potted gerbera, but do not contribute to the commercial quality of the plants. The use of cattle manure increases the availability of phosphorus in the soil for potted gerbera cultivation without, however, contributing to commercial quality. Potted gerbera is poorly responsive to phosphorus addition, supplied by both mineral and organic fertilizers.
