Abstract

The objective of this work was to evaluate nitrogen management alternatives using Azospirillum brasilense inoculation in wheat (Triticum aestivum) by seed and foliar applications. Treatments consisted of the inoculation or not of A. brasilense, via seed and leaves, associated with topdressing with 0, 70, and 140 kg h-1 nitrogen. Three wheat cultivars were tested: BRS Parrudo, TBIO Quartzo, and TBIO Sinuelo. The experimental design was a randomized complete block, with three replicates. The following traits were evaluated: number of emerged plants, tillers, spikelets per ear, grains per ear, and grains per spikelet; 1,000-grain mass; hectoliter mass; and grain yield. The foliar management of A. brasilense showed a better association with the TBIO Sinuelo cultivar. The foliar application of A. brasilense, whether alone or combined with seed treatment, increases the grain yield and yield components of the evaluated cultivars.
