Resumo: A field experiment in Cambé-PR was carried out with 20 treatments arranged in split plot with 4 replications in a randomized complete block design, using the soybean cultivar BRS 133. The treatments were CALPOT (0.0 and 2.35 t.ha-1) in the main plots, source of phosphorus (STP and SSP) in sub-plot, dosages of phosphorus (40 and 60 kg of P2O5.ha-1) in the sub-sub-plots, and density of plants (9 and 18 plants m-1) in the sub-sub-sub-plots. The greatest effect was on plant population, with the highest dry matter accumulation for the density of 200.000 plants ha-1 (9 plants m-1). The basic cation equilibrium in the soil helped to maximize this effect.

Os tratamentos foram combinados, potássio no momento da calagem - CALPOT (0,0 e 2,35 t.ha-1) nas parcelas, fontes de fósforo (STP e SSP) nas subparcelas, doses de P (40 e 60 kg. P2O5.ha-1) nas sub-sub-parcelas e densidade de plantas (9 e 18 plantas.m-1) nas sub-sub-sub-parcelas. De acordo com as variáveis analisadas, os maiores efeitos se restringiram à diferença entre as populações de plantas, com vantagem significativa para o acúmulo de matéria seca por planta (g) para população de 200.000 plantas por hectare (9 plantas por m). O equilíbrio de bases no solo por meio da aplicação de CALPOT contribui para maximizar esses efeitos.UEL2005-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/233710.5433/1679-0359.2005v26n4p477Semina: Ciências Agrárias; Vol. 26 No. 4 (2005); 477-484Semina: Ciências Agrárias; v. 26 n. 4 (2005); 477-4841679-03591676-546Xreponame:Semina.
