Resumo: | One of the main limitations of soybean production is related to water availability and organisms found in the soil. Under the hypothesis that soil moisture may influence the nematode population, this study aimed to verify the occurrence of nematodes associated with different irrigation management in soybean crops. The experiment was carried out in a randomized block design. Treatments consisted of a subplot scheme, with four replications. The plots consisted of ten irrigation managements divided into five irrigation frequencies (1,2,3,4, and 5 days) and five additional water depths (25, 50, 75, 100, and 125% of crop evapotranspiration – Etc). The subplots were composed of four different soybean cultivars (NA 5909 RR, AS 3680 IPRO, and Desafio RR ePower IPRO). The experiment analyzed the variables plant height, first pod insertion, number of plants, moisture, hundred-grain weight, yield, and occurrence of nematode eggs and adults. Nematodes influence all the production components analyzed, affecting mostly the hundred-grain weight, especially the nematode Helicotylenchus sp., although the Meloidogyne sp. population was larger. The phytonematode population reduces with the increase in soil moisture to levels close to the saturation, indirectly influencing the yield increase. |

Sob a hipótese de que a umidade do solo possa influenciar a população de nematoides, este estudo teve como objetivo verificar a ocorrência de nematóides associados a diferentes manejos de irrigação em lavouras de soja. O experimento foi conduzido em delineamento de blocos casualizados. Os tratamentos consistiram de um esquema de subparcelas, com quatro repetições. As parcelas consistiram de dez manejos de irrigação divididos em cinco freqüências de irrigação (1,2,3,4 e 5 dias) e cinco lâminas d'água (25, 50, 75, 100 e 125% da evapotranspiração da cultura - Etc). As subparcelas foram compostas por quatro diferentes cultivares de soja (NA 5909 RR, AS 3680 IPRO e Desafio RR ePower IPRO). O experimento analisou as variáveis altura da planta, inserção da primeira vagem, número de plantas, umidade, peso de cem grãos, produtividade e ocorrência de ovos de nematoides e adultos. Os nematóides influenciam todos os componentes de produção analisados, afetando principalmente o peso de cem grãos, especialmente o nematódeo Helicotylenchus sp., Embora o Meloidogyne sp. população era maior. A população de fitonematóides reduz com o aumento da umidade do solo para níveis próximos à saturação, influenciando indiretamente o aumento da produtividade.EDUFU2020-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4819710.14393/BJ-v36n5a2020-48197Bioscience Journal ; Vol. 36 No. 5 (2020): Sept./Oct.; 1645-1651Bioscience Journal ; v. 36 n. 5 (2020): Sept./Oct.; 1645-16511981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/48197/29624Brazil; ContemporaryCopyright (c) 2020 Ricardo Gava, Thiago Ramos da Silva, Mayara Fávero Cotrim, Alexandra Botelho Lima Abreu, Jefferson Luis Anselmo, Paulo Eduardo Teodorohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGava, RicardoSilva, Thiago Ramos daCotrim, Mayara FáveroAbreu, Alexandra Botelho LimaAnselmo, Jefferson LuisTeodoro, Paulo Eduardo2022-06-10T13:44:53Zoai:ojs.www.seer.ufu.br:article/48197Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-10T13:44:53Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
