“…As variáveis número de perfilhos, número de grãos por espiga e massa de mil grãos não apresentaram diferenças significativas entre os tratamentos, indicando não haver efeito da inoculação, associada ou não à adubação nitrogenada, nestes parâmetros da cultura. Por outro lado, Fukami et al (2016) observaram maior perfilhamento em trigo quando da inoculação das sementes, e destacaram que esse aumento pode ser considerado um dos mecanismos de promoção no rendimento em resposta à inoculação. Avaliando a inoculação com Azospirillum brasilense associada à aplicação de N mineral, Lemos et al (2013) obtiveram as maiores médias de grãos por espiga no trigo com a aplicações de N e/ou com N mais o inoculante.…”

“…Outros estudos encontraram resultados semelhantes (HUNGRIA et al, 2010;HUNGRIA, 2011), o que ajuda a reforçar a possibilidade de redução das quantidades de N aplicadas em cobertura quando é feita a inoculação das sementes. Fukami et al (2016) destacam que a substituição total da adubação nitrogenada pela inoculação pode não ser viável, contudo, a inoculação permite uma redução de cerca de 25% do N a ser aplicado na cultura.…”

“…A inoculação de sementes com Azospirillum brasilense é uma importante estratégia na busca por sistemas agrícolas mais conservacionistas (FUKAMI et al, 2016). No entanto, fatores relacionados ao clima, solo, microbiota do solo, cultivares utilizadas e de adubação podem influenciar a resposta do inoculante (JAMES, 2000), e devem ser considerados quando do estudo e recomendação da prática da inoculação.…”

“…A bactéria pode gerar diversos estímulos para o crescimento das plantas, destacando-se a fixação biológica de N (FUKAMI et al, 2016), produção de hormônios vegetais como auxinas, giberelinas e citocininas (CAVALLET et al 2000), solubilização de fosfato, maior desenvolvimento radicular (KAZI et al, 2016), aumento nos teores de clorofila e condutância estomática (HUNGRIA 2011), além de alterações na atividade fotossintética das plantas (GORDILLO-DELGADO et al, 2016). Ainda, quando crescem dentro da planta, podem aumentar a atividade da enzima nitrato redutase (HUNGRIA, 2011).…”

Resumo -O objetivo do estudo foi avaliar a eficiência agronômica da inoculação de sementes de trigo e de milho com Azospirillum brasilense, em associação à adubação nitrogenada. Sete tratamentos foram avaliados, associando a inoculação com aplicação de nitrogênio (N), sob delineamento de blocos ao acaso, com 4 repetições, totalizando 28 unidades experimentais com área individual de 27,2 m 2 . Na cultura do trigo foi avaliado o número de perfilhos por planta, número de espigas por metro quadrado, número de grãos por espiga, rendimento de massa seca e grãos, massa de mil grãos e peso hectolitro. No milho foi analisado o diâmetro de colmo, área foliar, índice de área foliar, altura de plantas, rendimento de grãos, massa de mil grãos, diâmetro e comprimento de espigas. Os resultados demonstraram que a inoculação não representou ganhos nos diferentes atributos avaliados. A associação da inoculação com adubação com N mineral aumentou a produtividade e a produção de matéria seca. A redução pela metade da adubação de N em cobertura, quando associada à inoculação, não afetou a resposta das culturas nos diferentes atributos avaliados. Conclui-se que a inoculação apresenta boa resposta nas culturas de trigo e milho quando associada à adubação nitrogenada. Palavras-chave: inoculação, produtividade, Triticum aestivum, Zea Mays.Abstract -The aim of the study was to evaluate the agronomic efficiency of wheat seed inoculation and corn with Azospirillum brasilense, in combination with nitrogen fertilization. Seven treatments were evaluated, involving inoculation with nitrogen (N), under design of a randomized block design with four replications, totaling 28 experimental units with individual area of 27,2 m². In wheat crop was rated the number of tillers per plant, number of ears per square meter, number of grains per spike, dry matter yield and grain, thousand grain weight and hectoliter weight. Maize was analyzed the stem diameter, leaf area, leaf area index, plant height, grain yield, thousand grain weight, diameter and length of spikes. The results showed that inoculation did not represent gains in different attributes evaluated. The association inoculation with fertilization with mineral N increased productivity and production of dry matter. The reduction by half of the fertilizer nitrogen in when associated with inoculation did not affect the response of crops in different attributes evaluated. It is concluded that the inoculation presents good response in wheat and corn crops when associated with nitrogen fertilization.

“…is also being increasingly adopted in several countries, especially for crops such as corn and wheat (Díaz-Zorita & Fernandez-Canigia, 2009;Hartmann & Bashan, 2009;Marks et al, 2015). The analysis of results from a large number of field trials with various non-legume crops, conducted worldwide over 20 years, under different soil and weather conditions, has demonstrated that yield increases of up to 30% could be obtained 70% of the time (Fukami et al, 2016;Fukami et al, 2017) in response to inoculation with Azospirillum.…”

There is a lack of more comprehensive research defining how much mineral N can be applied as regards the efficiency of BNF to attain high with Azospirillum brasilense, what is a bacterium that stands out for its biological nitrogen fixation (BNF) in corn crops, reaching economically sustainable yields. Moreover, it would be interesting to investigate the use of silicon, which exerts numerous benefits on grasses, especially when the plants are subjected to biotic and abiotic stresses. The aim of this work was to study a synergistic effect between the inoculation with A. brasilense and the application of silicon, thus enabling a higher efficiency of nitrogen fertilization, evaluating the grain yield of irrigated corn in economic terms. The experiment was conducted in Selvíria, MS, Brazil, under a no-till system, on a Latossolo Vermelho distrófico (Oxisol). The experiment was set up as a randomized block design with four replications, in a 2 × 5 × 2 factorial arrangement consisting of two soil corrective sources (dolomitic limestone and Ca and Mg silicate as source of Si); five doses of N (0, 50, 100, 150 and 200 kg ha -1 ); with and without inoculation with A. brasilense. The inoculation makes the corn increase much more profitable, irrespective of N doses and corrective source. The N dose of 200 kg ha -1 with dolomitic limestone, associated with inoculation provided greater grain yield. However, the highest economic return was obtained at the N dose of 100 kg ha -1 , with dolomitic limestone application and inoculation.

Maize (Zea mays L.) is a major cereal crop worldwide and demands N fertilizers, which can be replaced partially by plant growth-promoting bacteria. In Brazil, inoculants carrying Azospirillum brasilense strains Ab-V5 and Ab-V6 have exponentially grown, but a quantitative study on the replacement of N fertilizer by inoculants is still missing. Under greenhouse conditions, we investigated the effects of A. brasilense cells and metabolites applied via seeds or leaf-sprayed at the V3 growth stage on roots and confirmed strong benefits in traits that improve the uptake of water and nutrients.In the field, 30 trials were performed at 13 sites in Brazil over 10 yr, comparing noninoculated and inoculated maize receiving 0, 50, 75, and 100% (90 kg ha -1 of N) of N fertilizer (urea) applied as side-dress 35 d after emergence. Overall, inoculation significantly increased grain yield by 3.1%. Increases were confirmed in lower and higher yield levels, subtropical and tropical conditions, and clayey and sandy soils, with low and higher soil organic carbon levels. Yield increases due to inoculation were statistically significant at all levels of N fertilizer, except for at 50%. Inoculation with the supply of 75% of N increased yield by 4.6% compared with the noninoculated counterpart and, noteworthy, did not differ statistically from the non-inoculated control receiving 100% of N. These results confirmed the feasibility of replacing 25% of N-fertilizer applied as side-dress by seed inoculation with A. brasilense, besides the possibility of avoiding the emission of 4.95 million Mg of CO 2 -e per year. INTRODUCTIONAccording to the most accepted theory, maize (Zea mays L.) originated in Mesoamerica, more specifically in Mexico, about 7,000 yr ago. From there, the crop spread worldwide, reaching the position of the most produced cereal for humanAbbreviations: CFU, colony-forming units; CO 2 -e, CO 2 equivalents; DAE, days after emergence; DYGS, dextrose yeast glucose sucrose; GHG, greenhouse gases; IAA, indole-acetic acid; NFb, nitrogen-free broth.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
