This work aimed to study the flowering and fruiting of physic nut genotypes at different doses of phosphorus at the Cerrado ecosystem at the South of the Tocantins State. The experiments were performed in a completely randomized block design, with five treatments and six replicates. The treatments consisted of five doses of phosphorus P2O5 (0 g, 50g, 100g, 150g e 200g per hole), where each pant consisted of an experimental unit. The following characteristics were evaluated: total number of inflorescences or raceme, total number of flower buttons, total number of male flowers, total number of female flowers, total number of hermaphrodite flowers, total number of fruits, fraction of male and female flowers and flowering time. The evaluations were performed at two periods (8 a.m. and 5 p.m.). Results showed that genetic heterogeneity of the population prevented any statistical differences among the evaluated characteristics at the phosphorus doses used. However, the rate of 150 g/hole of P2O5 showed higher values for such evaluated characters. The fraction of male to female flowers was 18:1 and flowers opening were more frequent at the morning period. Physic nut plants present unisexual and hermaphrodite flowers.
