Resumo: | Garlic is a nutrient demanding crop which requires a high investment for fertilization and especially for phosphate (P) fertilizers, due to its high retention by the soil. It is possible to use the P solubilizing microbiota, especially rhizobacteria, to make P available and reduce fertilization. Fluorescent Pseudomonas spp. (CBS02) and Bacillus spp. (EB17) isolates were tested at triple superphosphate doses (0 % - without triple superphosphate; 50 % - 472.82 kg ha-1; 100 % - 945.65 kg ha-1). The experimental design was randomized blocks, in a 4 x 3 x 4 factorial scheme, with four treatments (CBS02 isolate, EB17 isolate, isolates mixture and control) and four replications. The size, fresh and dry masses, P content of the fourth leaf and yield were evaluated. The mixture of Pseudomonas spp. (CBS02) and Bacillus spp. (EB17) used in the inoculation of the garlic bulbils increased the size, dry mass and P content of the fourth leaf, as well as the yield of the crop without triple superphosphate, indicating that the P solubilization capacity of the isolates was increased when these were combined. It was possible to observe an increment in all the evaluated variables, indicating that the isolates P solubilization capacity was enhanced when they were combined.

KEYWORDS: Rhizobacteria, Alliaceae, phosphate nutrition.O alho é uma cultura exigente em nutrientes que requer alto investimento para adubação e, principalmente, fertilizantes fosfatados (P), devido à sua alta retenção pelo solo. É possível utilizar a microbiota solubilizadora de P, principalmente as rizobactérias, para disponibilizar P e reduzir a fertilização. Isolados de Pseudomonas spp. (CBS02) fluorescente e Bacillus spp. (EB17) foram testados em doses de superfosfato triplo (0 % - sem superfosfato triplo; 50 % - 472,82 kg ha-1; 100 % - 945,65 kg ha-1). O delineamento experimental foi em blocos ao acaso, em esquema fatorial 4 x 3 x 4, com quatro tratamentos (isolado CBS02, isolado EB17, mistura de isolados e testemunha) e quatro repetições. Avaliaram-se o porte, massas úmida e seca, teor de P da quarta folha e produtividade. A mistura de Pseudomonas spp. (CBS02) e Bacillus spp. (EB17) utilizada na inoculação de bulbilhos de alho aumentou o tamanho, a massa seca e o teor de P da quarta folha, bem como a produtividade da cultura sem superfosfato triplo, indicando que a capacidade de solubilização de P dos isolados foi aumentada quando foram combinados.
