Grain yield (kg ha−1) of maize in location of Cachoeira Dourada (A hybrid 2B707 HX), Luis Eduardo Magalhães (B hybrid 2B707 HX), and Ponta Grossa (C hybrid P4285 H), in response to different managements with N-fertilizer and inoculants with Azospirillum brasilense. All treatments received 24 kg of N ha−1 at sowing and N-treatments refers to the complementary N-fertilization applied at 35 days after emergence: 0 N (no N fertilizer); 100 N (100 % N); 75 N (25 % reduction in the complementary N fertilization). Inoculant doses: D1 (one standard dose, 1.0 × 105 cells seeds−1 or 1.0 × 105 cells plant−1); D2 (2 doses); D4 (4 doses). Inoculation methods: CONTROL (non-inoculated); SEED (standard seed inoculation); SOIL (soil spray inoculation at the V2.5 stage); FOLIAR (leaf spray inoculation at the V2.5 stage); FURROW (inoculation in the planting furrow at sowing). Yields were obtained from grains harvested in the central lanes of each replicate (8 m2), dried to 13 % of moisture and estimated to 1 ha. Means of six replicates and different letters indicate statistical difference (Duncan’s test at p ≤ 0.05)
