Abstract

The objective of this study was to evaluate the effects of phosphate rock powder application as substrate in the production of Paricá (Shizolobium amazonicum) seedlings. The experiment was carried out at the Forest Nursery of the Federal University of Tocantins, Gurupi campus, and was conducted in a completely randomized design consisting of 5 treatments: T1: 0% rock dust (PDR) + 100% commercial substrate; T2: 25% PDR + 75% Commercial Substrate; T3: 50% PDR + 50% Commercial Substrate; T4: 75% PDR + 25% Commercial Substrate; T5: 100% PDR + 0% Commercial Substrate), with 4 replications, where in each repetition the averages of 10 seedlings were evaluated. The effects of the addition of rock dust to the commercial substrate on the development of Shizolobium amazonicum species were observed. Shizolobium amazonicum seedlings produced with low proportions of rock dust to the commercial substrate had a good response (positive effect) on their development. Therefore, it is recommended to use a mixture of 25% PDR + 75% commercial substrate, increasing the substrate mineral levels, as this treatment allowed better germination performance, being more suitable for the effective production of seedlings of the species.: Paricá. Forest seeds. Substrate.
