ResumoAims: The research aimed to analyze the effect of five different dosages and three sources of phosphorus on the growth and development of young plants of pumpkins (Cucurbita moschata), cultivar Jacarezinho. Study Design: The experimental design utilized was the completely randomized design with the factorial arrangement 5 x 3 with three repetitions. Place and Duration of Study: The experiment was performed in a greenhouse of the Federal Rural University of Amazônia in the Capitão Poço City, Pará State. The research was carried out from March to April 2016. Methodology: The analyzed variables were plant height (PH), stem diameter (SD), number of leaves (NL), fresh root mass (FRM), fresh aerial mass (FAM), dry aerial mass, (DAM) and dry root mass (DRM) at 30 days after sowing. The averages of dosages x sources interactions were submitted to a regression analysis. Results: There was a significant effect of the interaction dosage x source for the PH, FAM and DAM. However, the dose of fertilizer got an effect on the SD, with linear response. The plots that did not reserve any fertilizers showed the least response for all variables. ARAD was the source that had the least performance in the analyzed variables in comparison to others sources. Conclusion: The superphosphate and triple superphosphate sources provided better development and accumulation of dry matter.
