Resumo: | The use of slow release fertilizer (SRF) can contribute to obtain better seedlings before an industry accustomed to the use of commercial fertilizers. This work aimed to evaluate doses of SRF on the growth of paricá tree seedlings and to compare the cost of conventional fertilizer use in relation to the cost involved in producing with SRF. The experimental design was completely randomized with 6 treatments and 4 replications of 40 plants, with one control and the other treatments with the addition of different doses of SRF per m³ of substrate used for seedlings production . After 81 days of sowing, it was analyzed total height, stem diameter, shoot fresh and dry weights, root dry weight, total biomass and maximum level of technical efficiency. Paricá tree seedlings responded positively to the use of SRF, presenting best results in parameters at doses ranging from 8.65 to 12.07 kg m-3 compared to control without SRF. Acquisition costs were higher when compared to conventional fertilization, requiring an economical and forestry analysis to infer on the feasibility of its use in the production and establishment of stands.
