Physical attributes of a pasture soil in southeast Goiás determined by geostatistics REA
Cardoso,Gabriel G. de G.; Wanderley,Rilley C.; Souza,Mara L. C..
ABSTRACT This study aimed to evaluate the spatial dependence of physical attributes in a soil cultivated with Brachiaria grass. A 12-m regular sampling grid was established within an area of 3.500 m2. Thirty-five soil samples were collected at 0-30 cm depth for particle density, bulk density, texture and total porosity analysis. These data were evaluated using statistical methods of indicator kriging and the GS+ software. The GS+ software was used to develop three-dimensional maps and evaluate semivariograms. The spatial dependence was evaluated using experimental semivariograms. The analyzed attributes indicated the occurrence of spatial dependence when fit to the exponential model. Areas with higher porosity occurred in the regions with lower bulk...

DEVELOPMENT OF A TRACEABILITY MODEL APPLIED TO GOAT AND SHEEP MEAT PRODUCTION REA
Bezerra,Alan C.; Pandorfi,Héliton; Gama,Rafael M.; Carvalho,Francisco F. R. de; Guiselini,Cristiane.
ABSTRACT: The goat and sheep meat producer chain has developed in last years, thus, it is imperative to organize and structure the supply chain and to adopt reliable policies for products' traceability, as a tool to achieve these requirements. The study aimed to make a management program with a traceability model for goat and sheep meat production, with emphasis on ensuring product origin and management practices' transparency at the animal production unit. For this purpose, it was made a reference model in order to emit an origin certificate which, in turn, provides specific information concerning the final product from each unit. Secondly, the program was developed using Hipertext Preprocessor (PHP) technology and as for the Database Management System,...

Efeito do manejo do solo na compactação e produção de melancia irrigada. Infoteca-e
CHOUDHURY, E. N.; MORGADO, L. B.; ANJOS, J. B. dos.
Determinar os efeitos de diferentes sistemas de preparo de solo sobre a compactacao e produtividade da melancia. Foi instalado no submedio Sao Francisco, em latossolo vermelho amarelo um experimento de blocos ao acaso em quatro repeticoes e com os tratamentos de aracao, aracao e gradagem, gradagem, subsolagem e gradagem. Os resultados mostram que um manejo racional desse solo proporciona boa produtividada, alem de evitar degradacao.

Comparative Performance of Organic, Conventional, and Integrated Producers in New Zealand AgEcon
Greer, Glen; Kaye-Blake, William; Hunt, Lesley.
The Agriculture Research Group on Sustainability (ARGOS) monitors a wide ange of environmental, social, economic and management parameters on matched cohorts of organic, conventional and integrated farms in the sheep/beef and kiwifruit sectors. Over six years significant differences have been found in farm costs and revenues between management systems, but few differences have been identified between management systems in “bottom-line” indicators of profitability, and there is greater variability within cohorts than between them. Regrouping of the properties according to farmer typologies does, however, result in the identification of some significant differences in economic outcomes between different “types” of farmers.

Implementation of a performance indicators system in a beef cattle company R. Bras. Zootec.
Rosado Júnior,Adriano Garcia; Lobato,José Fernando Piva.
It was aimed to propose a methodology for implementing a performance indicator system in a beef cattle company. Strategic goals and prioritization of process previously performed in the company was used as a support to the implementation. Possible indicators were listed and confronted with occasional restraints to its implementation and further analyzed by the Balanced Score Card (BSC) point of view. Subsequently, indicators were individually analyzed and their relationship with the company's strategic goals was determined. Seventeen indicators were selected, two under financial perspective, nine under process perspective, four under customer perspective, and two under development and learning perspective. The relationship analysis showed that the...

Building consolidated performance indicators for an agribusiness company: a case study R. Bras. Zootec.
Rosado Júnior,Adriano Garcia; Lobato,José Fernando Piva; Müller,Claúdio.
The objective of this study was to implement an indicator system that allows an overview of the performance at all levels of the company and to evaluate its overall performance using a consolidate general indicator. In the company studied, three business sectors were identified (crops, beef cattle production and viticulture) in addition to management sector, to which strategic objectives were determined. After that, it was mapped the macroprocesses that compose each business activity, a total of 14, and the critical indicators of performance to achieve the objectives, making up 50 indicators whose objectives were definied by the management team. It is possible to build consolidated indicators using the Analytic Hierarchy Process method, which allows...

Application of a model of management by macroprocesses to a beef cattle enterprise: a case study R. Bras. Zootec.
Rosado Júnior,Adriano Garcia; Lobato,José Fernando Piva.
This is a case study that aimed at proposing a management method based on macroprocesses to determine and achieve strategic goals for a beef cattle enterprise in order to maintain or to increase the company's competitiveness. The method suggests using a series of tools mentioned in the literature that were organized providing logical reasons for the managers to build the management system. When mapping the processes of the studied enterprise, four macroprocesses were identified, which were sustained by 21 support processes, in addition to three management processes. The strategic aims were determined by the internal and external environmental analysis, resulting in five priority items, and the processes considered critical to achieve them were described by...

Cover crop rotations in no-till system: short-term CO2 emissions and soybean yield Scientia Agricola
Rigon,João Paulo Gonsiorkiewicz; Calonego,Juliano Carlos; Rosolem,Ciro Antonio; Scala Jr.,Newton La.
ABSTRACT: In addition to improving sustainability in cropping systems, the use of a spring and winter crop rotation system may be a viable option for mitigating soil CO2 emissions (ECO2). This study aimed to determine short-term ECO2 as affected by crop rotations and soil management over one soybean cycle in two no-till experiments, and to assess the soybean yields with the lowest ECO2. Two experiments were carried out in fall-winter as follows: i) triticale and sunflower were grown in Typic Rhodudalf (TR), and ii) ruzigrass, grain sorghum, and ruzigrass + grain sorghum were grown in Rhodic Hapludox (RH). In the spring, pearl millet, sunn hemp, and forage sorghum were grown in both experiments. In addition, in TR a fallow treatment was also applied in the...
