Resumo: This work aimed to select the most efficient genotypes in phosphorus absorption and utilization in cerrado soils during corn second crop. The essay was constituted of 47 treatments (genotypes) and conducted at the experimental area of the Universidade Federal do Tocantins, Gurupi Campus. In order to simulate environments with high and low levels of phosphorus, doses of 25 and 113 kg ha-1de P2O5 were applied in the seeding, respectively. In order to identify the cultivars adequate to the environments, the study applied the methodology that suggest cultivar classification should be conducted according to use efficiency and response to phosphorus application (efficiency and response). It was concluded that the genotypes efficient in phosphorus absorption and utilization and responsive to P increase were UFVM77-0331, UFVM77-0307, UFVM77-0333, UFVM77-0381, UFVM77-0313, UFVM77-0305, UFVM77-0377 and UFVM77-0345.

O ensaio foi constituído de 47 tratamentos (genótipos) e foi conduzido na área experimental da Universidade Federal do Tocantins, Campus de Gurupi. Para simular ambientes com baixo e alto nível de fósforo, foram utilizadas doses de 25 e 113 kg ha-1de P2O5 na semeadura, respectivamente. Para identificar os cultivares adequados aos ambientes, utilizou-se metodologia que sugerem a classificação das cultivares quanto à eficiência no uso e resposta a aplicação do fósforo (eficiência e resposta). Concluiu-se que os genótipos eficientes na absorção e utilização de fósforo e responsivos ao incremento de P foram UFVM77-0331, UFVM77-0307, UFVM77-0333, UFVM77-0381, UFVM77-0313, UFVM77-0305, UFVM77-0377 e UFVM77-0345.Universidade Estadual de Maringá2010-04-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/263210.4025/actasciagron.v32i2.2632Acta Scientiarum.
