Resumo: | The effect of lime, S, Cu, Zn, B and Mo on the dry matter yield, number and dry weight of nodules of soybean (Glycine max (L) Merrill), variety Doko, was evaluated in ten paddy soils of the Cerrado Region. The soils showed a largo difference in their chemical and physical properties. The experimental design was an incomplete 26 factorial with two replications. The nutrients were applied on the basis of mg of each element per liter of dry soil (mg/1 ): 0 and 30 of S (elemental sulphur), 0 and 2 of Cu (CuCl), 0 and 3 of Zn (ZnO), 0 and 0.5 of B (H3BO3), 0 and 0.25 of Mo (Na2MoO42H2O), and, 0 and a quantity of lime determined by the SMP method sufficient to increase the pH of each soil to 5.5. A basic fertilization was used (mg/l): 100 of P and 127 of K (KH2PO4) and 73 of K (KCl). Eight out of the ten soils responded to lime. For the parameters evaluated (dry matter yield, number and dry weight of nodules), the response of the nutrients was in the following sequence: B>S>Cu>Zn. There was no effect of Mo on any of these parameters. An effect of the interactions lime x B, lime x S, lime x Zn, Cu x Zn and S x B on the dry matter yield, number and dry weight of nodules was observed. |

Merril), var. Doko, em dez solos de várzeas da Região dos Cerrados com ampla variação nas suas propriedades químicas e físicas. Utilizou-se como esquema experimental um fatorial fracionado 26, em dois blocos. Os nutrientes foram aplicados na base de mg do elemento por litro de solo seco (mg/1) :0 e 30 de S (enxofre elementar), 0 e 2 Cu (CuCl), 0 e 3 de Zn (ZnO), 0 e 0,5 de B (H3BO3 ), 0 e 0,25 de Mo (Na2 MoO4 2H2O), e, 0 e uma dose de calcário, determinada pelo método SMP, para elevar o pH de cada solo a 5,5. A adubação básica (mg/l) constou de 100 de P e 127 de K (KH2PO4), e mais 73 de K (KCl). Dos dez solos estudados, oito responderam à calagem. Quanto ao efeito de cada nutriente nos parâmetros avaliados (matéria seca, número e peso de nódulos), as respostas obedeceram à seguinte ordem: B>S>Cu>Zn. Não foi constatada resposta ao molibdênio. Houve efeito das interações calcário x B, calcário x S, calcário x Zn, Cu x Zn e S x B, nos parâmetros avaliados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGalrão, E. Z.Sousa, D.
