Pumpkins are cultivated worldwide, providing edible pulp and seeds. The use of silicon is a clean technology from the environmental perspective, which may provide several benefits to plants. The aim of this study was to evaluate the effects of the application of silicon derived from Sifol® and kaolin via seed treatment, in pumpkin, on the nutritional quality of seedlings. Five doses of silicon were applied via seed imbibition 0,1, 2, 4 and 5 mL 0.5L-1 for Sifol® and 0, 50, 100, 200 and 400 g.L-1 for kaolin, respectively. The genotype used was the early cultivar menina brasileira. Seedling chemical composition was evaluated using flame atomic absorption spectrometry.
