Summary: The study objective was to evaluate the corn nutrition through macronutrients levels in leaves of corn intercropped with forage species. The trial was conducted in second crop season in 2020, in Rio Verde city, GO, Brazil. The treatments were: corn (single), corn intercropped with Urochloa ruziziensis (Syn. Brachiaria ruziziensis), corn intercropped with Megathyrsus maximum (Syn. Panicum maximum) cv. BRS Tamani, corn intercropped with M. maximum cv. BRS Quênia and corn intercropped with M. maximum cv. BRS Zuri. The experimental design was in randomized blocks with four repetitions. For analysis of macronutrients content, it was collected five leaves of corn in flowering stage. The data was submitted to analysis of variance and compared by Tukey test at 5% of probability using SISVAR software. There was no difference in N, P, K, Ca, Mg and S content in corn leaves between intercropping systems. It indicates no interspecific competition for nutrients between corn and forage species intercropped. The forage species intercropping did not affect the macronutrients absorption of corn.
