Resumen: We have demonstrated that applications of low concentrations of sali cylic acid (SA) to the shoots of seedlings of plants or to perennial trees signifcantly increase their growth, development, and productivity. It is proposed that the positive effect of the SA of increasing the size of the roots favours the absorption and accu mulation of macro and micronutrients and contribute to biomass and seed produc tion. To test this hypothesis, we run experiments on Zea mays, Capsicum chinense and Solanum lycopersicum and measure their nutritional absorption after spraying, low concentrations (SA) to the canopy. The results have shown that (SA) signif cantly increases the length, weight and dry weight of roots, stems, leaves and yield of these species, as well as the levels of nitrogen (N), phosphorus (P) and potassium (K) in the different organs of the plants at the time of harvest. Copper, zinc, manga nese, iron, boron, calcium, and magnesium were also increased in most tissues by the effect of SA.
