The objective of this study was to evaluate the influence of the application of different doses of biofertilizer via fertigation on the production and accumulation of dry matter of yam rhizomes. The experimental design used was in randomized blocks, with five treatments and four replications. The treatments consisted of five doses of biofertilizer (D1 = 0 ml. plant-1; D2 = 30 ml plant-1; D3 = 60 ml plant-1; D4 = 90 ml plant-1; D5 = 120 ml plant-1). At 210 days after planting, the harvest was carried out and, by weighing with a precision scale, the production and dry matter of the rhizomes of yam were evaluated. These data were submitted to analysis of variance by the F test at 1 and 5%, and polynomial regression. It was found that the increase in the doses of biofertilizers applied via fertigation allowed an increase in production and dry matter, but with values below the average production.
