| A crescente geração de efluentes líquidos e o seu lançamento no meio ambiente tem-se constituído numa preocupação mundial devido aos impactos negativos gerados. O objetivo deste trabalho foi avaliar os possíveis impactos da aplicação do efluente proveniente da suinocultura, após seu tratamento, nos atributos químicos do solo, em área cultivada com algodão. O experimento foi realizado no Perímetro Irrigado Formoso, no município de Bom Jesus da Lapa, BA, em área experimental da Companhia de Desenvolvimento dos Vales do São Francisco e do Parnaíba - CODEVASF. Foram testados cinco tratamentos: MC - manejo convencional = água de "boa qualidade" + adubação química; ET100 = 100 % de efluente tratado; ET75:25 = 75 % de efluente tratado + 25 % de água boa; ET50:50... |

| ABSTRACTThe reduction on crop production observed in semiarid conditions is closely linked to soils degradation in their physical, microbiological and fertility aspects. Based on this premise, the effects of different types of organic fertilizers associated to the use of mulching in the production of cowpea grown in Paraíba state, Brazil, under semiarid conditions, was studied. The research was conducted under field conditions in the municipality of Casserengue, PB, from April to July 2010. The statistical design in randomized block design with five treatments and five replicates was used, totaling 25 experimental units. Treatments consisted on application of cattle manure or biofertilizer on presence or absence of mulch, plus a control treatment, without... |

| ABSTRACT Brackish waters may vary in their chemical compositions, interfering with different plant responses to stress; therefore, the present study aimed to evaluate the production components of parsley plants subjected to levels of electrical conductivity in nutrient solutions with an initial ECns of 1.58 dS m-1, which was solubilized in water with the following water electrical conductivity configurations (ECw): 0.12 (control), 1.12, 2.12, 3.12, 4.12 and 5.12 dS m-1, resulting in six isosmotic levels (ECns = 1.7, 2.7, 3.7, 4.7, 5.7 and 6.7 dS m-1) in an interaction with four types of salt: NaCl, CaCl2, MgCl2 and KCl. The experimental design was completely randomized in a factorial scheme with five replicates. Two strategies were used to restore the... |
