Corn is one of the most economically important crops in Brazil, and sowing it requires special attention to soil water availability. Magnetized water irrigation is an alternative to irrigation and seed treatment. Thus, the objective of this work was to evaluate the germination of corn seeds treated and irrigated with magnetized water. The experiment was carried out in May 2021 in a greenhouse at Fazenda Água Limpa, belonging to the University of Brasília (UnB). Corn seeds were subjected to four irrigation treatments with magnetized water, namely: magnetic induction of 0.28 T (T1), 0.229 T (T2), 0.029 T (T3) and 0 T (control). The variables evaluated were germination percentage, mean germination time, fresh seedling mass, dry seedling mass and seedling vigor. The design used was completely randomized, with five replications. Water magnetization was performed using three magnetizers, Jiangsu YLD Water Processing Equipment Co. Ltd. (T1), Structured Water Agriculture Magnetizer (T2) and Magnetizer Industrial Technologies Inc. (T3). The studied levels of magnetic induction in the irrigation water, as variables germination percentage and seedling vigor, differentiated among themselves at the level of 5%. Mean germination time, seedling fresh mass and seedling dry mass did not differ between treatments.
