![]() , informed that the supply of Si had a small influence on the production of dry matter, although it increased the number of panicles per plant at the highest concentrations of Si, and on the other hand, the concentration of Si decreased with the increment of the dose of fertilization with urea. In an accumulative crop of Si like rice, Andreotti et al. This fact is important because it is well-known that silicon can induce higher resistance to the plants in front of the pests. High nitrogen concentration and low concentrations of potassium increase the susceptibility of the corn plants to the noxious agents because it diminishes the absorption of Si. However, there are not enough results on the effects produced by the interaction of silicon, nitrogen, and potassium on the accumulation of these elements inside the vegetables and their implications on the growth of the plants. Some research report about the effect of the combinations of silicon and nitrogen on plants and silicon and potassium on the development of plants and yields, mainly in accumulative crops of silicon. Among the main accumulative crops of Si, are gramineous as sugar cane ( Saccharum spp.), rice ( Oriza sativa L.), and corn ( Z. On the other hand, silicon (Si) is not considered an essential element for plants, however, its absorption can produce beneficial effects in some crops, such as resistance to pests and diseases, attenuating abiotic stress and hydric stress. Nitrogen (N) and potassium (K) are essential elements for plants life being part of multiple structural compounds and participating in many vital processes. The application of silicon at a high concentration of K causes an increase in the accumulation of K, which is reflected in an increment of the total dry biomass in the plants of corn, while excess and a deficit of N diminish the accumulation of Si in the aerial part of the plant, which is more evident at a low concentration of K in the nutritious solution, affecting the accumulation of the total dry biomass. ![]() The foliar area, the dry biomass and, nitrogen, potassium, and silicon content were determined. A completely randomized design was used, with factorial arrangement 2 × 2 × 4 and three replications. ![]() Two silicon concentrations were evaluated (0 and 2 mmol L−1) two concentrations of potassium (1 and 12 mmol L−1) and four nitrogen concentrations: (1, 10, 15, and 20 mmol L−1). The research was developed under hydroponic conditions in Jaboticabal Sao Pablo, Brasil using the 30A77HX hybrid. The aim of the research was to evaluate the effect of the interaction of silicon, potassium, and nitrogen on the foliar area, the accumulation of these elements in the aerial part and the dry biomass in corn plants. ![]()
