TUCUCH-HAAS, C. J. et al. Use of Aspirine® (Acetylsalicilico acid) in the yield of grain of corn crop. Revista bio ciencias [online]. 2021, vol.8, e1035.  Epub 04-Out-2021. ISSN 2007-3380.  https://doi.org/10.15741/revbio.08.e1035.

Concentrations of 100, 1, 0.01 and 0.0001 µM of acetylsalicylic acid (ASA), using tablets of effervescent Aspirin® (500 mg of ASA) and well water as control, were applied in a foliar way to the canopy of corn plants, with seven days of age, established in field under an experimental design of randomized blocks, to test the tissue sensitivity of this cultivation and grain yield, starting from the premise that it has similar effects to its precursor molecule (salicylic acid). At the time of harvesting, data were collected on length and diameter of the cob, number of grains per row, weight of the seed and cob yield, by experimental plot and hectare. The results of this study indicate that plants were more sensitive to the application of 1 µM of ASA from commercial tablets, promoting a greater vegetative development, grain yield, and nutritional content (N, P and K) in the grain and vegetable tissues.
