Resumo: | The study of micronutrients accumulation as a function of plant development stage is of fundamental importance to subsidize strategies for fertilizer application and minimum amount to maintain soil fertility. This study evaluated micronutrient accumulation in two maize cultivars at different development stages. The experimental design was randomized blocks with four replications in split-plots, with two maize hybrids as the plots and sampling time according to development stages as sub-plots. Maize accumulated minimum amounts of B, Cu, Mn, and Zn in the initial stages of development, and the maximum accumulated values were observed after 100 days seedling emergency. The evaluated hybrids accumulated maximum of Zn and Cu close to physiological maturity. Maize plants accumulate nutrients in the above ground parts as follows: Zn > Mn > Cu > B. The total amount of nutrients required to produce one ton of corn is: 0.0009 kg B; 0.019 to 0.02 kg Cu; 0.042 to 0.046 kg Mn; 0.100 to 0.194 kg Zn. |

Neste trabalho, objetivou-se avaliar o acúmulo de micronutrientes em função dos estádios fenológicos da cultura, considerando dois híbridos de milho. O delineamento utilizado foi o DBC com quatro repetições, em esquema de parcelas subdivididas, sendo os dois híbridos de milho dispostos nas parcelas e, nas sub-parcelas, as épocas de coleta das plantas, considerando os estádios fenológicos da cultura do milho. Híbridos de milho acumulam quantidades mínimas de B, Cu, Mn e Zn nos estádios iniciais de desenvolvimento da cultura, sendo os valores máximos acumulados obtidos a partir de 100 dias após a emergência. Os híbridos de milho avaliados acumulam zinco e cobre até próximo à maturidade fisiológica, quando são obtidos os acúmulos máximos. Híbridos de milho acumulam micronutrientes em sua parte aérea na seguinte ordem decrescente: Zn>Mn>Cu>B. As quantidades de micronutrientes necessárias para produzir uma tonelada de grãos de milho são: 0,0009 kg de B; 0,019 a 0,020 kg de Cu; 0,042 a 0,046 kg de Mn; 0,100 a 0,194 kg de Zn.Editora da Universidade Federal de Lavras2009-08-012015-04-30T13:35:19Z2015-04-30T13:35:19Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542009000400011BORGES, I.
