In this work, the effect of different irrigation systems (flood vs. sprinkler irrigation), sprinkler irrigation management (low vs. high frequency, daytime vs. nighttime irrigation) and tillage practices (conventional tillage, no tillage with or without crop stover) on crop yield and the contamination with aflatoxins (AFs), fumonisins (FUM) and deoxynivalenol (DON) were evaluated in the maize grain from two experimental maize fields. No aflatoxins were detected in any of the samples analyzed. DON and FUM levels were significantly higher when the sprinkler irrigation was performed at nighttime (0.54 and 1.21 mg kg−1, respectively) as compared to daytime (0.38 and 0.45 mg kg−1). Likewise, DON and FUM were greater when irrigation frequency was low (0.61 and 1.09 mg kg−1, respectively) in comparison with high frequency (0.30 and 0.57 mg kg−1). DON concentrations were significantly higher in fields with sprinkler irrigation (0.53 mg kg−1) as compared to flood irrigation (0.19 mg kg−1), while the levels of FUM were very similar regardless of the maize irrigation system. Mycotoxin concentrations were not affected by the different soil tillage practices. This highlights the importance of implementing crop management practices to minimize the risk of mycotoxin contamination in maize. info:eu-repo/grantAgreement/ES/AEI/PID2019-106877RA-I00 info:eu-repo/grantAgreement/ES/MICINN/AGL2013-48728-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/AGL2013-49062-C4-4-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.3 2023 AGRONOMY 20 / 126 = 0.159 2023 Q1 T1 PLANT SCIENCES 65 / 265 = 0.245 2023 Q1 T1 0.688 2023 Agronomy and Crop Science 2023 Q1 6.2 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cavero, José Franco-Luesma, Samuel Álvaro-Fuentes, Jorge Universidad de Zaragoza Ariño, Agustín Universidad de Zaragoza (orcid)0000-0001-6325-7100 Lorán, Susana Universidad de Zaragoza (orcid)0000-0002-1961-8551 2008 640 Universidad de Zaragoza Dpto.
