Resumo: The maize crop, Zea mays L. (Poaceae), grown during the winter season “safrinha” in Parana State, southern Brazil, can be exposed to severe yield losses caused by unfavorable climatic events, depending on the planting date. In this paper, a methodology was adapted to assess the risk of frost during the crop cycle, with emphasis on the period between flowering and maturation, and the risk of water deficit during plant establishment and at flowering. Frost risk during the 30 days before maturation was considered as the most restrictive factor. Associating frost and water deficit risk, it was possible to identify eight distinct regions, with homogeneous planting dates of lower risk ranging from January to March

(Poaceae), é cultivado em parte do Estado do Paraná, em diversos tipos de solo e clima, podendo sofrer perdas elevadas provocadas por eventos climáticos desfavoráveis, dependendo da época de semeadura. Neste trabalho, foram realizadas análises dos riscos de geadas em todo o ciclo da cultura, com atenção especial ao período compreendido entre o florescimento e a maturação, bem como os de deficiência hídrica no estabelecimento e no florescimento, para identificar zonas homogêneas climaticamente e indicar as melhores épocas de semeadura para o estado. O risco de geada, nos trinta dias que antecedem a maturação, foi considerado o de maior restrição ao cultivo da “safrinha” de milho. Este fator, associado à combinação de menor risco de deficiência hídrica, permitiu a identificação de oito regiões distintas, com períodos de semeadura variando de janeiro a marçoUniversidade Estadual de Maringá2008-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/228110.4025/actasciagron.v24i0.2281Acta Scientiarum.
