“…Relative to the lower stratum, there was a linear increase in forage mass, leaf biomass and stem mass with increasing N rates (Figure 3) in the first and third cuttings, with no effect of inoculation. These results are related to an increase of stem size, the number of leaves and tillers when nitrogen is highly available in the soil for wheat (Ferreira et al, 2017).…”

The use of inoculants containing plant growth-promoting bacteria is an alternative to increase the efficiency of nitrogen fertilizers. Studies evaluating the effects of inoculation on forage yield, straw yield, and grain yield in dual-purpose wheat cultivars are scarce. This study aimed to evaluate the forage yield and grain yield in dual-purpose wheat inoculated with Azospirillum brasilense and fertilized with increasing nitrogen rates during two agricultural years (2016-2017) under cutting management. The trial was carried out in a completely randomized block design with four replicates, using a 2 x 4 factorial arrangement. The factors were the inoculation (control or A. brasilense) and nitrogen rates (0, 50, 100 and 150 kg ha-1 of N). Forage, grain and straw yield, and number of tillers were evaluated. Forage yield differed between treatments with inoculation and without inoculation, 3952 and 3350 kg DM ha-1, respectively. There was no effect of inoculation on grain yield. The forage and leaf biomass yield, the number of tillers and straw yield increased with inoculation.

“…However, differently from these authors as well as to Fukami et al (2016), in the present work any yield promotion can be attributed to tillering, as NTP data was not significant (Table 2). Nunes et al (2015) and Ferreira et al (2017) also did not reported any increase of NTP as result of inoculation and attributed the crop lack of response to Azospirillum spp. to the soil high N availability prior sowing.…”

The present work aimed to evaluate the agronomic performance of wheat grown under no-tillage system and submitted to different doses and methods of inoculation with Azospirillum spp. Eight treatments were tested: 1) control; 2) half N dose; 3) full dose of N; 4) half N dose + standarded inoculation by seeds (200 mL ha-1); 5) half N dose + in-furrow inoculation (200 mL ha-1); 6) half N dose + in furrow inoculation (300 mL ha-1); 7) half N dose + inoculation by foliar spraying (200 m ha-1) and 8) half N dose + inoculation by foliar spraying (300 mL ha-1). The following parameters were evaluated: number of tillers per plant, number of grains per spike, shoot dry biomass, weight of thousand seed mass, hectoliter weight, nitrogen content in grains, nitrogen content in shoot dry matter as well as crop yield. Our results showed that the supply of the half dose of mineral N associated to foliar inoculation with Azospirillum at the dose of 300 mL ha-1 provided positive results on wheat yield, confirming the bacterial ability to fix N. However, only the full mineral N fertilization stood out as the best N fertilization management.

“…(2017) reported that inoculation with A. brasilense in its liquid form via seed treatment, leaf application, or sowing furrow provided increases in wheat yield compared to the control treatment. On the other hand, Ferreira et al (2017) observed increases in wheat yield when inoculated with A. brasilense via seed and postemergence. However, the authors did not find significant increases when the inoculation was performed via leaf spraying.…”

Several studies have reported the beneficial effects of inoculation of Azospirillum brasilense in wheat, but only a few of them have related the co-inoculation of A. brasilense and Rhizobium sp. and the evaluation of different inoculation methods. This study aimed i) to verify the efficiency of plant growth-promoting bacteria (PGPB) in subtropical environments, ii) to verify the efficiency of co-inoculation of A. brasilense and Rhizobium sp., and iii) to verify the efficiency of the management of different inoculation methods in the wheat crop. The experiments were carried out in Londrina and Apucarana, State of Paraná, Brazil, under a complete randomized block design, with four replications and nine treatments: T1) absence of nitrogen (N) topdressing, T2) 30 kg ha−1 of N topdressing, T3) 60 kg ha−1 of N topdressing, T4) A. brasilense Ab-V5 in the seeds, T5) A. brasilense Ab-V5 in post-emergence, T6) A. brasilense Ab-V5 + Rhizobium sp. 53GRM1 in the seeds, T7) A. brasilense Ab-V5 + Rhizobium sp. 53GRM1 in post-emergence, T8) commercial inoculant (A. brasilense Ab-V5 + Ab-V6) in the seeds, and T9) commercial inoculant (A. brasilense Ab-V5 + Ab-V6) in post-emergence. The number of ears per linear meter, number of spikelets, number of grains per spikelet, number of grains per ear, thousand-grain weight, number of spikelets to ears ratio, leaf nitrogen content, and grain yield were evaluated. Leaf N content and yield components showed no alterations due to the inoculation and co-inoculation performed both in the seed and in the post-emergence of seedlings. Treatments T3, T7, and T9 showed the highest means of grain yield (2077.50, 1743.12, and 1660.62 kg ha−1, respectively), demonstrating that co-inoculation with A. brasilense Ab-V5 + Rhizobium sp. 53GRM1 and inoculation with A. brasilense Ab-V5 + Ab-V6, both in post-emergence of seedlings, have the potential to replace the topdressing nitrogen fertilization in wheat.
