This paper investigates the certified organic handler sector, a specialized component of the middle part of the farm-to-table marketing chain, and documents the impacts of firm agglomeration (or firm clusters) on firm-level performance or firm-level decisions. After accounting for endogeneity in firm clustering, our findings confirm that firm clusters have significant impacts, though the estimate of the impact depends on how a firm cluster is defined. For example, significant impacts on sales per employee range from an additional $0.17 million to $1.47 million, depending on whether a small or large number of firms is used as the minimum number to define a firm cluster. |

The objective of this study was to evaluate the influence of vitamin C (VC), vitamin E (VE), and two selenium sources on the performance, yield, and composition of Nile tilapia fillet. The experiment was conducted in a completely randomized design consisting of six treatments with the addition of 100, 200, and 400 mg kg-1 VC and VE and 0.1, 0.2, and 0.4 of two sources of selenium. Each treatment had five replicates of 30 fish each. The diet with 200 mg kg-1 VC and VE + 0.2 mg.k-1 organic selenium resulted in weight gain, length gain, and feed conversion ratio similar to that of the treatment with 400 mg kg-1 VC and VE + 0.4 mg kg-1 organic or inorganic selenium. The addition of organic selenium to the diet improved the weight gain and feed conversion ratio... |

RESUMO: Avaliou-se, neste trabalho, o efeito de sistemas de manejo no fluxo de CO2 do solo numa rotação soja-milho, durante um período de 398 dias, de abril de 2000 a maio de 2001, em um Latossolo Vermelho-Escuro argiloso, na Embrapa Cerrados, em Planaltina, Distrito Federal. Foram selecionadas uma área com vegetação de Cerrado (CE) e seis parcelas de um experimento de longa duração (20 anos): arado de discos pré-plantio (ADPP); arado de discos pós-coheita (ADPC); plantio direto a partir do segundo em área preparada com arado de discos em 1979 (PDAD); arado de aivecas pré-plantio (AVPP); arado de aivecas pós-colheita (AVPC); e plantio direto a partir do segundo ano em área preparada com arado de aivecas em 1979 (PDAV). Utilizaram-se dois métodos: um... |
