Última Reference Values of Grain Nutrient Content and Removal for Corn 90 Duarte,Aildson Pereira; Abreu,Mônica Ferreira de; Francisco,Eros Artur Bohac; Gitti,Douglas de Castilho; Barth,Gabriel; Kappes,Claudinei. ABSTRACT: Unchanged reference values of grain nutrient contents for corn have been used for over 20 years, despite yield increases, the development of new hybrids, and modifications to cropping systems, especially the establishment of in-season second crops and the wide adoption of no-tillage. This study measured macro- and micronutrient contents in corn grains from different regions, in the first (summer) and second (fall) crop, to update the reference values of estimated nutrient removal. A secondary objective was to determine whether there were correlations between grain nutrient contents and grain yields and densities. In this study, 175 corn grain samples of experiments on cultivar evaluation and 22 samples from soil management trials from five states...

Ano: 2019 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-06832019000100517 The relationship between fungi growth and aflatoxin production with ergosterol content of corn grains 58 Castro,Maria Fernanda Penteado Moretzsohn de; Bragagnolo,Neura; Valentini,Sílvia Regina de Toledo. The relationships between fungal growth and ergosterol content and between aflatoxins B1 and B2 production and ergosterol content were verified in corn grains. In the first experiment, fungal growth and ergosterol content were monitored during incubation of corn grains presenting water activities of 0.85a w and 0.92a w at 25ºC over a period of 18 days. For the Taiúba variety, the fungi growth and ergosterol content increased more rapidly for 0.92a w than 0.85a w. Maximum ergosterol levels were 2.8 and 4.6 µg/g, respectively, for 0.85a w and 0.92a w. For the Cargill hybrid 606, a more pronounced increase in fungal growth was verified just at the end of the incubation period, mainly for 0.92a w when an acentuated increase in ergosterol content was also...
