Abstract

SZILAGYI-ZECCHIN, Vivian J.; MARRIEL, Ivanildo E.  and  SILVA, Paulo R. F. da. Productivity of maize inoculated with Azospirillum brasilense with different doses of nitrogen cultivated in Brazilian field. Rev. de Ciências Agrárias [online]. 2017, vol.40, n.4, pp.110-119.

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.

Keywords : inoculation; diazotrophic bacteria; Ab-V5; Zea mays; yield.
