Avaliou-se, em casa de vegetacao, o efeito do calcario, S, Cu, Zn, B e Mo na producao da materia seca, numero e peso de nodulos da soja (Glycine max (L.) Merril), var. Doko, em dez solos de varzeas da Regiao dos Cerrados com ampla variacao nas suas propriedades quimicas e fisicas. Utilizou-se como esquema experimental um fatorial fracionado 2, 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), O e 2 Cu (CuC1), 0 e 3 de Zn (ZnO), 0 e 0,5 de B(H3BO3), 0 e 0,25 de Mo (Na2MoO42H2O), e, O e uma dose de calcario, determinada pelo metodo SMP, para elevar o pH de cada solo a 5,5. A adubacao basica (mg/1) constou de 100 de P e 127 de K (KH2PO4), e mais 73 de K (KC1). Dos dez solos estudados, oito responderam a calagem. Quanto ao efeito de cada nutriente nos parametros avaliados (materia seca, numero e peso de nodulos), as respostas obedeceram a seguinte ordem: B>S>Cu>Zn. Nao foi constatada resposta ao molibdenio. Houve efeito das interacoes calcario x B, calcario x S, calcario x Zn, Cu x Zn e S x B, nos parametros avaliados. |

Great part of solid waste are deposited inappropriately near cities or in rural areas, contributing to negative environmental impacts. There are numerous forms of waste processing, one of them is pyrolysis to produce biochar and subsequent use in agricultural systems. The objective of this study was to evaluate different substrates with activated biochar (AB) and biochar (B) in substrate and its effect on the growth of passion fruit seedlings. The test was conducted in a nursery, located in Sinop/MT, May to July 2013, designed in four blocks with ten treatments: commercial substrate (CS), composed by pine bark and vermiculite 4:1; nursery substrate (NS) composed by carbonized rice husk and coconut fiber 1:1; and the eigth treatments represented were B and AB additions of 25; 50; 75; and 100% in CS, (B25, B50, B75, B100, AB25, AB50, AB75 and AB100, respectively). After 60 days sowing the stem diameter, plant height, leaf number was evaluated and at the end of the experiment the fresh and dry weight of shoots and roots, and Dickson Quality Index (DQI) were assessed. AB at concentrations of 25, 50 and 75% combined with commercial substrate showed increases in parameters fresh and dry biomass weight, height, stem diameter and number of leaves. The dose of 25% AB is presented as the best dose to be adopted in commercial crops. The sawdust processed into AB is an alternative in the production of passion fruit system and the reintegration of this raw material to the productive sector.
