Teores de proteína e óleo em grãos de soja com inoculação mista azospirillum e bradyrhizobium em região de baixa latitude

Abstract

A soybean crop is one of the major sources of raw material for a biodiesel production, without Brazil, besides being one of the main sources of nutrients for the supply of proteins for animal or human feeding. In this sense, the objective of this work was to evaluate the influence of the Azospirillum foliar inoculation, in association with Bradyrhizobium, in the oil contents, aiming at the biodiesel production and in the protein contents, aiming to add value to food products, in grains of soybeans grown in a low latitude region. Three experiments were carried out in Palmas - TO, being sowing performed on 11/18/2015, 12/02/2015 and 12/17/2015. The experiments were performed without a randomized block design with three replicates. The cultivars TMG 1288RR and M 9144 were used, and in the subplots five doses of commercial applications of A. brasilense commercial product (0, 100, 200, 300 and 400 mL ha- 1 of the commercial product per hectare). The nominal characters consisted of the protein content (Kjeldahl) and the oil (Soxhlet) in the grains and yield of protein and oil. After obtaining the data, perform a joint analysis of the experiments performed. The results show that they occur in grain nutrients and reduce our effects of use with mixed use of Azospirillum and Bradyrhizobium at all planting seasons and in all cultivars. As high and low temperatures precipitate contributions to increase and decrease, respectively, the oil and protein products of the beans. For the production of biodiesel, the use of Azospirillum concomitant with the use of Bradyrhizobium is not recommended. Increasing doses of Azospirillum promoted increased protein content and reduced oil content. The oil content and inversion related to the owner, regardless of the planting season.
