AGRONOMIC PERFORMANCE OF WHEAT CULTIVARS IN RESPONSE TO INOCULATION (Azospirillum brasilense) AND NITROGEN APPLICATION

ABSTRACT The objective of this work was to verify the contribution seed inoculation with bacterium Azospirillum brasilense promote growth on yield components in wheat crop. For this, experiments were carried out different locations (Santa Maria and Cruz Alta, RS, Brazil), sowing times (June July) years cultivation (2013 2014). A randomized block design three replications used. treatments composed by combination ten cultivars, nitrogen managements two types (10 x 3 2). Inoculation liquid inoculant seeds. grain evaluated. average number tillers per plant influenced (1.63 1.72) when uninoculated inoculated, respectively. On other hand, hectoliter mass responded inversely, reducing 75.7 kg hL-1. A. increased (1%) had no positive influence variables ears spikelets ear, weight.
