1. Phytonematode population dynamics in common bean cultivation under crop rotation and no-tillage conditions
ABSTRACT Strategies for conserving natural resources and reducing agricultural inputs are the great challenge for agriculture, such as sustainable alternatives to control agricultural pests of high economic impact, e.g. plant-parasitic nematodes. This work aimed to evaluate phytonematode’s population dynamics in common bean cultivation grown under crop rot

2. AVANÇOS NA PRODUÇÃO E FORMULAÇÃO DE INOCULANTES MICROBIANOS VISANDO UMA AGRICULTURA MAIS SUSTENTÁVEL
The wide application of beneficial microorganisms in agriculture as inoculants to combat pests and diseases and/or to improve soil fertility and the nutrients availability for plants has been considered as an effective and more sustainable alternative than chemical fertilizers and agricultural defensives. However, it is necessary to examine all processing st

3. FERTILIZER RECOMMENDATION METHODS FOR PRECISION AGRICULTURE – A SYSTEMATIC LITERATURE STUDY
ABSTRACT Spatial variability management of soil chemical attributes is one of the approaches to be employed in the face of the constant challenge of increasing agricultural yield to meet world demand. In this sense, precision agriculture has as one of its tools the application of inputs at varying rates, which seeks to determine the ideal amount of fertilize

4. Spatial Distribution and Pollution Assessment of Trace Elements Pb, Cu, Ni, Fe and As in the Surficial Water of Staring Bay, Indonesia
Staring Bay has long been used by the local community for fisheries and fishing activities; however, the rapid population growth and industrial activities around the bay in recent years are predicted to contribute significantly to the increase of waste entering the bay. This particular study was aimed to provide baseline levels of trace elements Pb, Cu, Ni,

5. THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with ex

6. O impacto das cooperativas na produção agropecuária brasileira: uma análise econométrica espacial
Resumo Como importantes elos de ligação entre os produtores e o mercado, e respondendo direta ou indiretamente por relevante parte do Produto Interno Bruto agropecuário nacional, as cooperativas carecem de estudos que mensurem o quanto são capazes de influenciar a produção no meio rural, considerando as diferenças regionais brasileiras. Assim, este tr

7. Is arbuscular mycorrhizal fungal species community affected by cotton growth management systems in the Brazilian Cerrado?
Abstract: Conventional cotton production in western Bahia, Brazil, involves intensive use of agricultural inputs and mechanization, which may affect arbuscular mycorrhizal fungi (AMF). This work aimed at studying the impact of conventional and organic cotton production in the AMF of western Bahia. Soil samples were obtained from conventional white cotton and

8. Biodiversity Conservation in Agricultural Landscapes: the Importance of the Matrix
ABSTRACT Agricultural matrices can lead to landscape homogenization, culminating in losses of biodiversity and ecosystem services. Agricultural management is determinant for developing conservation strategies. In this review, we discuss the influence of the agricultural matrix on biodiversity at different scales. Intensive agriculture under agrochemicals and

9. Fair Value of Biological Assets: An Interdisciplinary Methodological Proposal
Resumo Dada a complexidade de se mensurar o fair value de ativos biológicos agrícolas, que geralmente não possuem um mercado ativo e são dependentes de fatores climáticos, ambientais e biológicos, surge a necessidade de uma visão interdisciplinar que considere outros inputs além dos econômicos e contábeis. Nesse sentido, o presente ensaio teórico

11. Vegetation Burning in Pampa Biome Altered the Chemical Composition of Rainfall
ABSTRACT Rainfall is one of the primary nutrient inputs to vegetation and its chemical composition is dependent on air quality as falling rain scavenges gaseous and particulate emissions from natural, industrial, and agricultural activities. The objective of this study was to evaluate whether the vegetation burn in a region of the Pampa biome influences the

12. Selection of maize top-crosses for different nitrogen levels through specific combining ability
ABSTRACT An alternative to increase yield without raising the production costs and minimizing the dependence of agricultural inputs is the development of maize genotypes presenting high nitrogen (N) use efficiency under low N level conditions. Thus, the objective of this study was to estimate the specific combining ability of maize top-crosses under high and
