“…There was no significant interaction between inoculation and nitrogen splitting for the studied parameters (p> 0.05). Many studies have reported the benefits of Azospirillum-plant interactions (Longhini et al, 2016;Nakao et al, 2018). However, plant responses to inoculation can be influenced by cropping conditions such as soil pH, temperature, and humidity (Cardoso et al, 2010;Hungary, 2011).…”

“…Moreover, the high cost of nitrogen fertilizers has driven research into natural N fixation and plant growth-promoting bacteria (PGPB) studies, as these supply all or part of the N demanded by crops or help absorb nutrients at low cost and less environmental impact (Hungria, 2011). In this context, studies on Azospirillum brasilense inoculation in grasses have exhibited several benefits to host plants, such as morphological and nutritional changes, increase in crop yield, among others (Longhini et al, 2016;Nakao et al, 2018).…”

Nitrogen fertilization in crop sorghum during the off-season may have a lower cost-benefit ratio than expected, due to the residual effect of the predecessor crop. However, the use of growth-promoting bacteria can be an economical alternative to increase crop yield in the Cerrado. The objective was to evaluate the response of grain sorghum to nitrogen fertilization and its inoculation by A. brasilense. A complete randomized block design in a 5 x 2 factorial arrangement was used, with five replications of the following treatments: recommended amount of N (120 kg ha-1 of N-urea), divided into 0 %-100 %, 25 % -75 %, 50 %-50 % and 100 %-0 %, in sowing and coverage, respectively, and the control (without N); with and without inoculation via sorghum seed. The morphological and productivity components of the crop were evaluated. The application of 100 % of N in the sowing provided larger plants and the 50 %-50 % installment provided smaller plants. The plants did not respond to inoculation by A. brasilense. The yield components of sorghum grown in succession to soybean, rainfed, do not change due to A. brasilense inoculation and supply or installment of nitrogen fertilization.

“…It was expected that intercropped plants could modify the growth habit, due to possible intraspecific competition for luminosity; tillers increase to stem height, and reduce their diameter (Nakao et al, 2018) making plants more prone to lodging. However, this event was not observed in intercropping (Table 1), indicating that the population of plants used allowed the coexistence of grasses throughout the silage production cycle.…”

Maize and forage sorghum crops have a relevant economic importance in Midwest Brazil and there is a need for more information for their intercropping as a strategy for the farmers to reduce inputs. The objective of this work is evaluate if forage sorghum and maize intercropping effects agronomic traits, the bromatological characteristics of silage from the consortium at different times of silo openings, and the economic viability of all crop systems. This experiment was carried on in the field with seven treatments, consisting of monoculture and intercropping of corn and sorghum hybrids. Monoculture of sorghum Agri 001 and maize Agri 320, as well as in maize Agri 320, Agri 340 and Agri 104 intercropped with sorghum Agri 001 had the highest biomass yield. Intercropped maize did not have lodging, reduction in height, nor decrease in the first ear height in relation to the intercropped plants. Maize hybrids intercropped with sorghum led to a better fermentation pattern of silages, reducing ammonia concentrations. However, due the higher contents of NDF and the lower TDN contents of sorghum, nutritional values of intercropped silages were generally smaller than when they were composed only with maize. It was observed that the monoculture of sorghum Agri 001 for silage showed a higher profit compared to the other treatments.

“…O gênero Azospirillum spp pode estimular a produção de fitohormônios, como auxinas, giberilinas e citocininas (Hungria, 2011). Estes, são capazes de proporcionar maior desenvolvimento das raízes, auxiliando na maior absorção de água e nutrientes (Nakao et al, 2018). Ocasionando alterações nas estruturas morfológicas e reprodutivas, bem como a histologia dos tecidos vegetais (Hungria et al, 2010).…”

A inoculação com Azospirillum brasilense apresenta potencial de uso na cultura do sorgo (Sorghum bicolor [L.] Moench) pela possibilidade de alterar a fisiologia e morfologia das plantas. Neste sentido, o presente estudo tem por objetivo avaliar a influência da inoculação via semente com a bactéria promotora de crescimento da estirpe Azospirillum brasilense sobre a composição morfológica, parâmetros fermentativos, perdas nutricionais, frações nitrogenadas e de carboidratos em silagem de sorgo do híbrido AG 2005. O delineamento experimental foi o inteiramente casualizado, constituindo-se de dois tratamentos (com e sem inoculação), com quatro repetições de silos. O fracionamento nitrogenado, foi determinado conforme descrito por Licitra et al. (1996) e para mensurar o fracionamento dos carboidratos, foi avaliado de acordo com a metodologia proposta por Lanzas et al. (2007). As plantas inoculadas apresentaram menor porcentagem de colmo, mas houve maior participação de panícula mais grãos. O híbrido inoculado produziu silagem com menor teor de nitrogênio insolúvel em detergente ácido (NIDA) e nitrogênio insolúvel em detergente neutro (NIDN). Com relação ao fracionamento de carboidratos, as silagens de sorgo com inoculação diferiram significativamente em CHO (carboidratos totais) e CC (fibra indigestível) em relação ao controle. Sobre o fracionamento proteico, a fração indigestível (PC), a inoculação apresentou redução de 0,29 unidade percentuais quando comparado ao controle. Desta forma, a inoculação de sementes com A. brasilense pode ser uma alternativa viável, pois apresenta potencial de reduzir a fração de proteína e glicídios insolúvel e indigestível no trato gastrointestinal em silagens de sorgo.
