Abstract
Phosphorus is important to plant growth due to its storage and energy transference processes and its involvement in the active absorption of other nutrients.The aim of this study was to evaluate the nutritional status of yellow passion fruit plants under fertilization from different P 2 O 5 sources and rates.Treatments were distributed in randomized blocks in a 2 × 5 factorial design, with two phosphorus sources (simple and triple superphosphate) and five P 2 O 5 doses of 0, 12, 18, 24 and 30 g hole -1 .A total of two applications were performed at 60 and 120 days after seedling transplanting; P 2 O 5 doses of 0, 24, 36, 48 and 60 g hole -1 were equivalent to 0, 27, 40, 53 and 67 kg hole -1 of P 2 O 5 from each superphosphate source, respectively.When the orchard was in fructification, 150 days after seedling transplanting, individual leaf samples were harvested from the median branches of the plants in each parcel in order to evaluate N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn and Na contents.The phosphate fertilization promoted adequate nutrition for passion fruit plants of N, P, K, Mg and S, independent of the source provided, but adequate Ca only for doses up to 36 g hole -1 of P 2 O 5 .Plants were impaired in B, Cu, Fe and Mn, except for Fe in those not fertilized with P 2 O 5 and those treated with 24 and 36 g hole -1 of P 2 O 5 in simple superphosphate form.Considering the adequate nutritional value of passion fruit, it is recommended to fertilize with 36 g hole -1 year -1 of P 2 O 5 , whether simple or triple superphosphate.
