This work verified the physiological quality of seeds of two maize cultivars treated in isolation and in association with an inoculant based on Azospirillum brasilense, biostimulants and a liquid fertilizer. The experiment was designed in a completely randomized 2x8 factorial scheme, comprising two maize cultivars (P30F53 and P30F53YH) and eight seed treatments (untreated; treated with inoculant; treated with biostimulants; treated with liquid fertilizer; treated with inoculant and biostimulant; treated with inoculant and liquid fertilizer; treated with biostimulant and liquid fertilizer; treated with inoculant, treated with liquid fertilizer and biostimulant). Percentage of germination, emergence in sand, germination speed index, cold test, and dry mass of shoots and root of seedlings were evaluated. The cultivar P30F53YH had seeds with better physiological quality compared with the cultivar P30F53 when treated with biostimulants, liquid fertilizer and Azospirillum. The biostimulant, liquid fertilizer and Azospirilum. either on their own or in combinations not involving the liquid fertilizer do not impair physiological qualityof maize seeds.
