Produtividade de milho inoculado com Azospirillum brasilense em diferentes doses de nitrogênio cultivado em campo no Brasil

The yield of corn inoculated with A. brasilense and nitrogen doses was evaluated in the field. In the treatments with nitrogen (N) it was used 0%, 50% and 100% of N (the usual dose ranges from 100 to 120 kg N ha-1), combined with seeds without inoculation, inoculated with two strains (Ab-V5 and Ab-V6) and inoculated only with Ab-V5. On average, the dose of 0% N with Ab-V5, showed better productive performance, being equivalent to the use of 50% N without inoculant. With the use of 50% N, the two inoculants promoted the highest yields, compared to the uninoculated plants, similar to that obtained with 100% N without inoculation.
