Resumo -O presente trabalho foi desenvolvido com o objetivo de avaliar a influência das formas de inoculação deAzospirillum brasilense no crescimento inicial do triticale. O delineamento utilizado foi de blocos casualizados com quatro repetições, em esquema fatorial 4x2. O primeiro fator foi composto por quatro formas de inoculação de Azospirillum brasilense (sem inoculação, inoculação na semente, inoculação no sulco de semeadura e inoculação via foliar, sendo esta realizada aos 10 dias após a emergência). O segundo fator foi composto por dois cultivares de triticale (IPR Aimoré e BRS Harmonia). A inoculação de Azospirillum brasilense na semente reduziu a porcentagem de emergência e o índice de velocidade de emergência do triticale, dependendo do genótipo. As formas de inoculação de Azospirillum brasilense de forma geral não influenciaram o crescimento inicial do triticale. A resposta das plantas à inoculação de Azospirillum brasilense foi variável, dependendo basicamente do genótipo de triticale.Palavras-Chave: X Triticosecale Wittmack., fixação biológica, aplicação foliar.Abstract -The present trial was developed with the objective of evaluating the influence of inoculation modes of Azospirillum brasilense on the initial growth of triticale. The experimental design was randomized blocks with four replicates, in 4x2 factorial scheme. The first factor was composed by four inoculation methods of Azospirillum brasilense (without inoculation, inoculation in the seed, inoculation in the sowing furrow and foliar inoculation at 10 days after an emergency). The second factor was composed by two triticale cultivars (IPR Aimoré and BRS Harmonia). The inoculation of Azospirillum brasilense in the seed can reduce the emergency percentage and the index of emergence speed of triticale, depending on the genotype. In general, the inoculation modes of Azospirillum brasilense did not influence the initial growth of triticale. The response of the plants to the inoculation with Azospirillum brasilense is variable, depending essentially on the triticale genotype.
