Resumo: Despite positive results in growth promotion of maize with inoculation of diazotrophic bacteria, it has been shown that there are variations in the interactions between hybrids and these bacteria. The aim of this study was to evaluate the efficiency of rhizobia symbionts of legume and diazotrophic bacteria inoculation on growth promotion of maize hybrids. Maize plants grown in pots of five maize hybrids were inoculated with the rhizobia UFRGS VP16 and SEMIA 222 and a combination of three diazotrophic bacteria of the genus Azospirillum (UFRGS Lg1-R, UFRGS El-S and UFRGS MS). The bacteria inoculation showed growth promoting response dependent on maize hybrids. Inoculation of rhizobia UFRGS Vp16 increased growth of maize hybrid 30F53, NB 7205, 30R50 and Formula, but not has growth promotion effect on the hybrid maize AS 1572. Inoculation combination of three isolates of Azospirillum increased growth of maize hybrid 30F53, NB 7205 and AS 1572, but not has growth promoting effect on the hybrids 30R50.

O objetivo deste trabalho foi avaliar a eficiência da inoculação de rizóbios, simbiontes em leguminosas, e bactérias diazotróficas associativas na promoção de crescimento de híbridos de milho. Plantas de milho de cinco híbridos cultivadas em vasos foram inoculadas com os rizóbios UFRGS Vp16 e SEMIA 222 e a combinação de três bactérias diazotróficas associativas do gênero Azospirillum (UFRGS Lg1-R, UFRGS El-S e UFRGS M-S). A inoculação das bactérias mostrou haver respostas na promoção de crescimento dependentes dos híbridos de milho. A inoculação do rizóbio UFRGS Vp16 aumentou o crescimento dos híbridos de milho 30F53, NB 7205, 30R50 e Fórmula, porém não teve efeito de promoção de crescimento sobre o híbrido de milho AS 1572. A inoculação combinada de três isolados de Azospirillum aumentou o crescimento dos híbridos de milho 30F53, NB 7205 e AS 1572, porém nos híbridos 30R50 e Fórmula não teve efeito de promoção de crescimento. Departamento de Diagnóstico e Pesquisa Agropecuária.
