1 RESUMO
Objetivou-se avaliar a influência da aplicação de diferentes doses de biofertilizante via fertirrigação, sobre a produção e acúmulo de matéria seca de rizomas de inhame. O delineamento experimental utilizado foi em blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos foram compostos por cinco doses de biofertilizante (D1 = 0 ml planta-1; D2 = 30 ml planta-1; D3 = 60 ml planta-1; D4 = 90 ml planta-1; D5 = 120 ml planta-1). Aos 210 dias após o plantio realizou-se a colheita e através de pesagem com balança de precisão avaliou-se a produção e a matéria seca dos rizomas de inhame. Esses dados foram submetidos a análise de variância pelo teste F a 1 e 5%, e regressão polinomial. Constatou-se que o aumento das doses de biofertilizantes aplicado via fertirrigação possibilitou incremento na produção e matéria seca, mas com valores inferiores à média produtiva.

YAM PRODUCTION AND DRY MATTER FERTILIZED WITH BIOFERTILIZER
2 ABSTRACT
This study aimed 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 a randomized block, 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.
