Resumo: Systems of soil cultivation and use directly influence crop yield by interfering with the soil chemical, physical, and biological attributes. This study aimed to evaluate the correlation between maize grain yield, soil chemical and biological attributes, and the occurrence of nematodes in maize crops grown in the off-season, in the state of Mato Grosso do Sul. Soil samples from 21 off-season maize crops were collected in 2015. The samples were used to identify and quantify nematodes, determine biomass carbon and microbial activity, and for chemical analysis. The attributes were clustered based on the variables evaluated using the mean Euclidean distance and Ward's clustering method.  The interrelationship between the variables was analyzed by correlations, and its unfolding in the cause and effect investigations was evaluated by the path analysis. Organic matter and microbial biomass carbon positively influence grain yield. Magnesium negatively influences the population of Pratylenchulus spp. in maize crops. The potential acidity and organic matter are related to the presence of Rotylenchulus spp.

Este trabalho teve como objetivo avaliar a correlação entre a produtividade de grãos de milho, os atributos químicos e biológicos do solo e a ocorrência de nematoides em milho cultivado no período de entressafra, no estado do Mato Grosso do Sul. Amostras de solo de 21 safras de milho fora de temporada foram coletadas em 2015. As amostras foram usadas para identificar e quantificar os nematóides, determinar a atividade microbiana e o carbono da biomassa, e para análises químicas. Os atributos foram agrupados com base nas variáveis avaliadas usando a distância euclidiana média e o método de agrupamento de Ward. A inter-relação entre as variáveis foi analisada por meio de correlações, e seu desdobramento nas investigações de causa e efeito foi avaliado pela análise de trilha. A matéria orgânica e o carbono da biomassa microbiana influenciam positivamente o rendimento de grãos. O magnésio influencia negativamente a população de Pratylenchulus spp. nas culturas de milho. A acidez potencial e a matéria orgânica estão relacionadas à presença de Rotylenchulus spp.EDUFU2020-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/48143Bioscience Journal ; Vol. 36 No. 6 (2020): Nov./Dec.; 1845-1857Bioscience Journal ; v. 36 n. 6 (2020): Nov./Dec.; 1845-18571981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/48143/30386Brazil; Contemporary Copyright (c) 2020 Valquiria Krolikowski, Gessi Ceccon, Katiane Secco Castro, Paulo Eduardo Teodorohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKrolikowski, ValquiriaCeccon, GessiCastro, Katiane SeccoTeodoro, Paulo Eduardo2022-05-26T18:25:45Zoai:ojs.www.seer.ufu.br:article/48143Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-26T18:25:45Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
