Resumo: | The efficient production of cotton in soils with low levels of phosphorus (P) require a better understanding of the interference of plant adaptations in relation to P stress, about the absorption, transport and use of other nutrients such as nitrogen (N). Thus, the selection of genotypes efficient in the use of N in low P supply conditions is an effective tool for proper plant development. Hear, was to evaluate the nitrogen use efficiency in Gossypium barbadense L. genotypes grown in an adequate and low phosphorus availability conditions. For that were tested 14 genotypes of pima cotton, grown in two level of P supply: adequate and low level. We evaluated the concentration and accumulation of N, as well as the N efficiency of absorption, transport and use. The genotypes grown under low P supply showed higher leaf N, indicating clear synergistic relationship between N and P. The MT 92 genotype showed a higher capacity to absorb and transport of N in low P supply in the soil conditions. The MT 105 genotype showed higher capacity of conversion N in biomass. The genotypes studied were characterized as a source of genes for adaptation to low P availability for the use of N, are indicated for genetic improvement in the cotton crop (Gossypium hirsutun L). |

Nitrogen use efficiency in pima cotton genotypes under phosphorus applicationEficiência no uso de nitrogênio por genótipos de algodoeiro arbóreo sob aplicação de fósforoThe efficient production of cotton in soils with low levels of phosphorus (P) require a better understanding of the interference of plant adaptations in relation to P stress, about the absorption, transport and use of other nutrients such as nitrogen (N).

Assim, a seleção de genótipos eficientes no uso do N em condições de baixo suprimento de P é uma ferramenta eficaz para obter o desenvolvimento vegetal adequado. Este trabalho foi realizado com o objetivo de avaliar a eficiência do uso de N em genótipos de algodoeiro, em diferentes disponibilidades de P. Foram testados 14 genótipos de algodoeiro, cultivados em dois suprimentos de P ̶ adequado e baixo nível. Foram avaliados a concentração e o acúmulo de N, bem como as eficiências de absorção, transporte e uso de N. Os genótipos cultivados em baixo suprimento de P apresentaram maior concentração de N foliar, indicando relação de sinergismo entre o N e o P. O genótipo MT 92 demonstrou maior capacidade de absorção e transporte de N em condições de baixo suprimento de P no solo, enquanto o MT 105 demonstrou maior capacidade de conversão de N em biomassa. Os genótipos foram caracterizados como fonte de genes de adaptação à baixa disponibilidade de P para o uso de N, sendo indicados para o melhoramento genético no cultivo de algodoeiro.Universidade Federal Rural da Amazônia/UFRA2016-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/1892Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 58 No 4 (2015): RCA; 357-364Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 58 n. 4 (2015): RCA; 357-3642177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
