The study was carried out in two consecutive years with <em>J</em>.<em> curcas</em> plants with 3 years old in 3x2 m spacing. The assays were set up with randomized complete block design with five concentrations (</span><span>0, 10, 20, 40 and 80 mM L<sup>-1</sup></span><span>) and five replications. It was set up another experiment in a greenhouse following completely randomized factorial design 5x2 with five silicon concentrations (</span><span>0, 10, 20, 40 and 80 mM L<sup>-1</sup></span><span>) and two water supply: daily irrigation with water volumes according to 50% and 100% of evapotranspiration, six replications and one plant per plot. The present study allows clarifying that <em>J</em>. <em>curcas</em> plants are non-accumulating plants, for accumulating less than 1% of silicon in the leaves. The low accumulation of silicon in the leaves did not significantly inferred in growth of <em>J</em>. <em>curcas</em>, however, the reduction of specific leaf area possibly occurred by the formation of a thin silica layer and reduced the yield by the decrease sunlight absorption. The silicon did not mitigated the damages by <em>Cophes notaticeps</em> and <em>Polyphagotarsonemus latus</em> by the low ability of the plant to accumulate silicon, however, is possible to affirm that the injuries severity by <em>Cophes notaticep</em>s is proportional to stem diameter.</span>}, number={2}, journal={Acta Iguazu}, author={Matos, Fabio Santos and Caramori, Samantha S. and Zago, Leciana M. and Parreira, Gabriel Santin and Amaro, Camila Lariane and e Silva, Felipe de Oliveira and Rossato, Liana Verônica and Amorim, Victor Alves}, year={2021}, month={jun.}, pages={100–113} }
