Peanuts are an important legume for the Northeastern Brazilian market, but their production in this region is low. The present study aimed to evaluate the effect of biofertilizer doses on peanut nodulation and production components, to define the best dose and genotype. The experiment was conducted in a completely randomized block design (DBC) in a 3 x 3 factorial arrangement, with three replications. The treatments consisted of two evaluation factors: 1) Fertilization via different doses of organic fertilizer applied to the substrate (D1 = 0mL; D2 = 500mL; and D3 = 1000mL); and 2) Peanut genotypes (BR-1, UNI43 and UNI08). The following traits were assessed: number of nodules per plant (NNP), number of mature pods (NVM), pod mass per plant (MVP), seed mass per plant (MSP) and root length (CR). Peanut production is affected by fertilization via bovine biofertilizer, mainly for the components NVM, MVP and MSP. Besides, nodulation is a likely conditioner. The 1000mL dose proved to be the best treatment for the traits analyzed, and UNI08 accession, the most responsive material. |
