Resumo: | Co-inoculation consists of using microorganism combinations with synergic effect that surpass the results obtained with their use alone. The objective of this work was to evaluate the effect of inoculation and co-inoculation on soybean plants, and their residual effect on maize plants grown intercropped with ruzigrass (Urochloa ruziziensis), under different N fertilizer rates. The experiment was conducted at the experimental area of the Mato Grosso State University, Alta Floresta campus, in a Typic Hapludox. A randomized block design was used for the soybean crops; the treatments consisted of Bradyrhizobium japonicum inoculated single, or co-inoculated with Azospirillum brasilense, with 20 replications. A randomized block design in a strip-plot arrangement was used for the winter maize-ruzigrass intercrop (WMRI); the treatments consisted of combination of residual effect of inoculation and co-inoculation in the strips, and five N fertilizer rates (0, 50, 100, 150, and 200 kg ha-1) in plots with WMRI, with four replications. The co-inoculation of soybean seeds and its residual effect on the maize crops increased the root dry weight of plants of both crops; however, no increases were found for most vegetative and reproductive characteristics of maize plants. Yield and most characteristics evaluated had increasing linear responses to increases in N rates, indicating the plants could respond to rates above 200 kg ha-1. |

A coinoculação consiste no uso de combinações de micro-organismos, os quais produzem efeito de sinergismo, ultrapassando resultados produtivos obtidos de forma isolada. Objetivou-se avaliar o efeito da inoculação e coinoculação sobre a cultura da soja e seus reflexos sobre a cultura do milho sob doses de nitrogênio (N) no sistema de consórcio milho + braquiária. O experimento foi instalado na área experimental da Universidade do Estado de Mato Grosso – UNEMAT, Campus de Alta Floresta em LATOSSOLO VERMELHO-AMARELO Distrófico. Para a cultura da soja o delineamento utilizado foi blocos ao acaso, sendo os tratamentos constituídos pela inoculação com Bradyrhizobium japonicum com e sem a coinoculação com Azospirillum brasilense, com vinte repetições cada. O delineamento para cultura do milho foi em faixa, sendo os tratamentos experimentais constituídos pela combinação do resíduo da inoculação e da coinoculação na faixa e cinco doses de N (0, 50, 100, 150 e 200 kg ha-1), aplicadas no milho safrinha consorciado com Urochloa ruziziensis nas parcelas, com quatro repetições. A coinoculação das sementes de soja e o resíduo da coinoculação no milho elevaram a massa seca da raiz para as duas culturas, porém esse incremento não se deu para a maioria das características vegetativas e reprodutivas avaliadas no milho. Para a produtividade e também para a maioria das características avaliadas ocorreu resposta linear crescente com o aumento das doses de N aplicadas, indicando que poderia haver respostas a doses superiores a 200 kg ha-1.
