Resumo: | Reducing the use of mineral fertilizers and environmental pollution during agricultural production is a growing need, as is the improvement of techniques for growing corn, a grass of great social and environmental importance. To this end, studies that lead to increased productivity with reduced production costs and impacts on the environment are essential. In this way, the objective was to evaluate different sources of nitrogen for the cultivation of corn in the region of Doutor Camargo-PR, thus reducing the dependence of production on chemical fertilizers and assisting in the regional agricultural sustainability. The following treatments were evaluated: T1 - Witness; T2 –50 kg.ha¹ of N in coverage; T3 – Azospirillum brasilense via leaf; T4 - Application of Bacillus subtilis via leaf; T5 - Azospirillum brasilense and Bacillus subtilis via leaf. The evaluated parameters were: plant height; grain yield; thousand grain mass and economic valuation. The data obtained were submitted to the F test, when significant to the means, they were compared by the Scott-Knott Test, at 5% probability, using the Sisvar software. The application of Bacillus subtilis via leaf provided significantly increased plant height and greater economic return for the producer in relation to the other treatments analyzed, while the application of this bacterium associated with Azospirillum brasilense did not provide benefits in relation to the control. Thus, it is concluded that the use of Bacillus subtilis is a profitable alternative to the rural producer and provides a more sustainable production system, reducing the need for chemical fertilization to make nitrogen available. |

Para tal, estudos que acarretem aumento de produtividade com redução de custos de produção e impactos ao meio ambiente se fazem essenciais. Deste modo, objetivou-se avaliar diferentes fontes de nitrogênio para a cultura do milho na região do noroeste do Paraná, atenuando assim a dependência da produção aos fertilizantes químicos e auxiliando na sustentabilidade agrícola regional. Foram avaliados os seguintes tratamentos: T1- adubação na base; T2 – Adubação na base + aplicação de Bacillus subtilis via foliar; T3 – Adubação na base + aplicação de Azospirillum brasilense via foliar; T4 – Adubação de base + aplicação de Azospirillum brasilense e Bacillus subtilis via foliar e T5 – Adubação de base com + 50 kg.ha-¹ de N em cobertura. Os parâmetros avaliados foram: altura de plantas; produtividade de grãos; massa de mil grãos e avaliação econômica. Os dados obtidos foram submetidos ao teste F, quando significativo às médias foram comparadas pelo Teste Scott-Knott, a 5% de probabilidade, utilizando o software Sisvar. A aplicação de Bacillus subtilis via foliar proporcionou de forma significativamente o aumento da altura das plantas e maior retorno econômico para o produtor em relação aos demais tratamentos analisados, enquanto a aplicação desta bactéria associada a Azospirillum brasilense não proporcinou benefícios em relação a testemunha. Assim, conclui-se que o uso de Bacillus subtilis é uma alternativa rentável ao produtor rural e proporciona um sistema de produção mais sustentável diminuindo a necessidade de adubação química para disponibilização de nitrogênio.UNIVERSIDADE CESUMARBrasilUNICESUMARGASPAROTTO, FrancielliGASPAROTTO, FrancielliPACCOLA, Edneia Aparecida de SouzaRIGHETTI, José SérgioMACHADO, Raphael Willian BegoCALVI, Vinicius de Oliveira2021-02-12T18:13:34Z2021-02-122021-02-12T18:13:34Z2021-02-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMACHADO, Raphael Willian Bego; CALVI, Vinicius de Oliveira.
