2. CONDITIONAL FDH EFFICIENCY TO ASSESS PERFORMANCE FACTORS FOR BRAZILIAN AGRICULTURE
ABSTRACT In this article we assess the effect of market imperfections and income inequality on rural production efficiency. The analysis is carried out using the notion of stochastic conditional efficiency computed in terms of free disposal hull (FDH) efficiency measurements. Free disposal hull and conditional FDH are output oriented with variable returns to

3. Fronteira de produção e eficiência técnica da agropecuária brasileira em 2006 / Production frontier and technical efficiency of Brazilian agriculture in 2006
Os pequenos estabelecimentos, apesar de mais numerosos e ocuparem menor área que os médios e grandes estabelecimentos, geram parcela muito importante da produção agrícola brasileira, a despeito de as políticas agrícolas brasileiras terem, de meados dos anos 1960 a meados dos anos 1980, criado mais mecanismos para a modernização dos médios e grandes

5. A parametric approach for evaluating the technical efficiency of the brazilian agricultural sector.
In this study we assessed the technical efficiency of the 27 Brazilian states in the years 1995/96 and 2006. The ata on land and labor were otained from the agricultural census of the two considered periods. Data on credit for investment and running costs were obtained from the Brazilian Central Bank reports. In the analysis we used a DEA CCR model and a sto

7. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

8. Do global ao local: percursos teÃricos e conceituais da sustentabilidade
Sustainabilityâs discussion is fertile and controversial. Authors have different opinions about this issue, and it always treated in conjunction with the discussion of sustainable development. Our initial hypothesis is that the explicitness failure about SD, was linked to the difficult to comprehend the term sustainability. After that, we observe that was n

9. Fundamentação da cobrança pelo uso da água na agricultura irrigada, na microbacia do Ribeirão dos Marins, Piracicaba/SP / Fundamentation of water use charges in agricultural irrigation, in the smallcatchment basin of River Marins, Piracicaba/SP
The current crisis in water supply worldwide and the associated water use problems are one of the great concerns for the humanity, leading to the necessity to find solutions to prevent harmful consequences in the environment. Charges for water use in agricultural irrigation, supported by principles of environmental law as "user-payer" and "pollut

10. CARACTERIZAÇÃO DA VARIABILIDADE ESPACIAL DAS CARACTERÍSTICAS QUÍMICAS DO SOLO E DA PRODUTIVIDADE DAS CULTURAS, UTILIZANDO AS FERRAMENTAS DA AGRICULTURA DE PRECISÃO. / CHARACTERIZATION OF THE SPATIAL VARIABILITY OF THE SOILS CHEMICAL CHARACTERISTICS AND PRODUCTIVITY OF CULTURES, USING THE TOOLS OF PRECISION AGRICULTURE.
In this work were investigated the spatial variability existent on the soil attributes utilized for soil fertility evaluation and its grade of participation on the yield crop variability. An experiment was conducted over five years (2000 to 2005) in an area of 57 ha in the municipality of Palmeira das Missões in a Latossolo Vermelho distrófico típico (EMB

12. Parametros reprodutivos masculinos e fertilidade de ratos adultos expostos ao inseticida fenvalerato / Male reproductive parameters and fertility of adult rats exposed to fenvalerate
Fenvalerate is a synthetic pyrethroid insecticide widely used in agriculture to control a variety of insects. Although it is considered to be of low acute toxicity to mammals, studies have showed that pyrethroids can have estrogenic activity and can act as endocrine disruptors, causing important reproductive impairment in males. It is documented in the liter
