Resumo: | The soybean is grown in virtually all states in Brazil for a total of 36 million ha. The Midwest region stands out as the largest producer of grain in Brazil. With the expansion of the soybean crop, new problems arose, among them, the diseases caused by phytonematodes. Pratylenchus brachyurus has become a major problem for national soybean, as it causes great losses and does not have many control methods. The damages caused by this phytoparasite are aggravated in a no-tillage system, considering that this system does not cause the soil to be disturbed. Thus, the objective of the work was to evaluate the influence of limestone doses after two years of application and planting system in the management of P. brachyurus in soybean grown in the municipality of Nova Xavantina, region of Vale do Araguaia Matogrossense. The experiment was carried out in a commercial field naturally infested with the nematode. The experimental design used was in randomized blocks, in a 5x2 factorial scheme, with the treatments: 5 limestone doses (0, 1.25, 2.5, 3.75 and 5 t / ha) and 2 cultivation systems (planting no-tillage and conventional tillage using a leveling harrow). The plots were demarcated with the dimensions of 5x6 m and distributed in 4 blocks. The collection of soil and roots for nematological analyzes were carried out when the soybean was at the reproductive stage R5.4, in January 2018 and 2019, to evaluate the population of P. brachyurus. The beans were harvested for productivity analysis. In the first year, a reduction in the population of Pratylenchus brachyurus in the roots was observed in the order of 34.8% in the harrow system when compared with the no-till system, in the second year this value was even greater, reaching 85.3%. Under the conditions of study, the use of the grid was efficient to reduce the nematode population in both harvests. The application of lime did not have a reduction effect on the nematode population, but it did increase soybean productivity. The no-till system was efficient to increase soybean productivity. |

A região Centro-Oeste se destaca como a maior produtora do grão no Brasil. Com a expansão da cultura da soja surgiu novos problemas, dentre eles, as doenças causadas por fitonematoides. O Pratylenchus brachyurus se tornou um grande problema para a sojicultura nacional, pois causa grandes perdas e não possuem muitos métodos de controle. Os danos causados por este fitoparasita são agravados em sistema de plantio direto, tendo em vista que este sistema não há o revolvimento do solo. Assim, o objetivo do trabalho foi avaliar a influência das doses de calcário após dois anos agrícola da aplicação e do sistema de plantio no manejo de P. brachyurus em soja cultivada no município de Nova Xavantina, região do Vale do Araguaia Matogrossense. O experimento foi conduzido em lavoura comercial naturalmente infestada com o nematoide. O delineamento experimental utilizado foi em blocos ao acaso, em esquema fatorial 5x2, sendo os tratamentos: 5 doses de calcário (0; 1,25; 2,5; 3,75 e 5 t/ha) e 2 sistemas de cultivo (plantio direto e plantio convencional com uso de grade niveladora). As parcelas foram demarcadas com as dimensões de 5x6 m e distribuídas em 4 blocos. A coleta do solo e das raízes para análises nematológicas foram realizadas quando a soja estava no estádio reprodutivo R5.4, em janeiro de 2018 e 2019, para avaliação da população de P. brachyurus. Os grãos foram colhidos para a análise de produtividade. No primeiro ano observou-se redução da população de Pratylenchus brachyurus nas raízes na ordem de 34,8% no sistema de grade quando comparado com o sistema de plantio direto, no segundo ano este valor foi ainda maior, chegando a 85,3%. Nas condições de estudo, a utilização da grade foi eficiente para reduzir a população de nematoide nas duas safras. A aplicação do calcário não apresentou efeito de redução na população do nematoide, mas aumentou a produtividade da soja. O sistema de plantio direto foi eficiente para aumentar a produtividade da soja.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Exatas e da Terra (ICET) – AraguaiaUFMT CUA - AraguaiaAgronomia - CUAFerreira, Paulo Afonsohttp://lattes.cnpq.br/8261047896794489Ferreira, Paulo Afonsohttp://lattes.cnpq.br/8261047896794489Moraes, Milton Ferreira dehttp://lattes.cnpq.br/1541223007968886Favero, Silviohttp://lattes.cnpq.br/1731131570007530Silva, Samuel de Oliveira2022-06-14T21:08:52Z2020-03-052022-06-14T21:08:52Z2020-02-18info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetSILVA, Samuel de Oliveira.
