Resumo: This work was carried out to study the effect of nitrogen fertilization on grain amaranth yield, in Maringá, north of Paraná state. It was done in feld conditions, using a complete randomized design, with four treatments and three replicates. Seeds were sowed in lines, spaced each 0.5 m. Fertilization was done with NPK 10-10-10 (350 kg/ha). Fifteen days after germination there was left a population of 20 plants m-1. Thirty days after germination felds received nitrogen fertilizer (urea, 45% N), and doses were 0; 50; 100; 200 kg N ha-1. Plants were cut 114 days after germination, to measure the following parameters: plant height;  stem diameter;  fresh  and dry biomass yield of  stems  and  leaves;  and  seed yield. Plant height and grain production showed quadratic response. Stem diameter showed no differences. Biomass production  (fresh and dry)  showed  linear  response. Yield of amaranth grains answered positively  to nitrogen fertilization.

Este  trabalho  foi  realizado para avaliar o efeito da adubação nitrogenada em cobertura, na produção de  amaranto  em Maringá, norte do Paraná. Foi  realizado  em  condições de  campo, no delineamento inteiramente casualizado, com quatro tratamentos e três repetições por tratamento. As sementes foram semeadas em linhas espaçadas a cada 0,5 m. A adubação de plantio foi feita com NPK 10-10-10 (350 kg ha-1). Aos 15 dias após a emergência, foi feito o desbaste para deixar uma população de 20 plantas m-1. Aos 30 dias após a emergência, foi aplicada adubação nitrogenada de cobertura (uréia, 45% N), nas doses 0; 50; 100; 200 kg N há 1. Aos 114 dias após a emergência, foram medidos os parâmetros: altura da planta; diâmetro do colmo; produção de biomassa fresca e seca da parte aérea; e produção de grãos. A altura da planta e a produção de grãos apresentaram uma resposta quadrática. Não houve diferenças signifcativas para o diâmetro do colmo. A biomassa da parte aérea (fresca e seca) teve uma resposta linear. O amaranto respondeu favoravelmente à adubação nitrogenada de cobertura.UEL2008-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/268810.5433/1679-0359.2008v29n4p761Semina: Ciências Agrárias; Vol. 29 No. 4 (2008); 761-768Semina: Ciências Agrárias; v. 29 n. 4 (2008); 761-7681679-03591676-546Xreponame:Semina.
