Resumo: | The objective this work was to evaluate the nutrients accumulation and achenes oil yield in sunflower plants as affected by achenes vigour and sowing density. An experiment was installed in the field at Seropédica, State of Rio de Janeiro, in October 2006 with three lots of sunflower achenes, cultivar Embrapa 122 V2000, classified as low, medium and high vigour and two sowing density (45,000 e 75,000 seeds.ha-1). The collected were realized at 20, 60 and 100 days after planting (DAP) to the determination the dry mater, nitrogen, phosphorus, potassium and calcium. In the collecting at 100 DAP too it was evaluated the achene yield (kg ha-1), the content oil and oil yield (kg ha-1). The results indicated that to the 60 days high accumulation of dry mater, N, P K and Ca in stem, leaves and total at density of 45,000 seeds ha-1. The sunflower achenes oil yield and achenes and nutrients harvest index not affected by the achenes vigour and sowing density to. There was a preferential translocation of N and P for the achenes. |

Para isto, foi instalado um experimento no campo experimental no município de Seropédica/RJ, em outubro de 2006, com três distintos lotes de aquênios de girassol cv Embrapa 122 V2000, classificados como de baixo, de médio e de alto vigor, sob duas densidades de semeadura (45.000 e 75.000 sementes ha-1). Aos 20, 60 e 100 dias após a semeadura (DAS), foram coletadas as plantas para avaliação da massa de matéria seca e do acúmulo de nitrogênio, de fósforo, de potássio e de cálcio, no caule, nas folhas e nos capítulos. Nas plantas coletadas aos 100 DAS, foi feita também a avaliação do rendimento de aquênios (kg ha-1), do teor de óleo e do rendimento de óleo (kg ha-1). Observou-se que aos 60 DAS, no período entre o florescimento e o enchimento, ocorreu maior acúmulo de massa de matéria seca e de N, P, K e Ca no caule, nas folhas e total nas plantas de girassol produzidas sob a densidade de 45.000 sementes ha-1. Não houve efeito do vigor dos aquênios e da densidade de semeadura no rendimento de óleo dos aquênios de girassol e nos índices de colheita de aquênios e nutrientes. Houve translocação preferencial de N e P para os aquênios.UEL2011-02-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/280910.5433/1679-0359.2010v31n4Sup1p1193Semina: Ciências Agrárias; Vol. 31 No. 4Sup1 (2010); 1193-1204Semina: Ciências Agrárias; v. 31 n. 4Sup1 (2010); 1193-12041679-03591676-546Xreponame:Semina.
