1. Population Structure and Fruit Productivity Analyses in Support of the Use of Caryocar brasiliense
ABSTRACT The Brazilian Cerrado, a global biodiversity hotspot, has been widely converted by agricultural expansion and pasture establishment. As a result of these activities, several plant species have experienced population declines such as pequi (Caryocar brasiliense ). We analyzed the feasibility of economic use of C. brasiliense based on population stru

2. FINANCIAL ANALYSIS OF THE INVESTMENT IN PRECISION AGRICULTURE TECHNIQUES ON COTTON CROP
ABSTRACT: The aim of this study was to evaluate a financial analysis by the use of precision agriculture (PA) techniques on cotton crop. The experiment was carried out in a cotton field of 91 ha and its result compared to another field with similar area, cultivated with the conventional agricultural techniques. The financial analysis was extrapolated to the

3. Germination test as a fast method to detect glyphosate-resistant sourgrass
The occurrence of weed species with different levels of resistance to glyphosate has increasingly spread in agricultural areas. In Brazil, sourgrass is among the main species presenting issues in this regard. Thus, fast and reliable methods to detect glyphosate resistance are of special interest for this specie, either for research or rational management pur

4. AN EVOLUTIONARY STUDY ON CROP PRODUCTION IN SMALL FARM SYSTEMS IN THE MID-WEST REGION OF BRAZIL BASED ON A LINEAR PROGRAMMING MODEL
Based on an agro-technical study for the mid-west region of Brazil, and considering financial conditions like monthly expenses and long-term investments, a mixed integer and dynamic linear model has been proposed for representing crop production systems. This model establishes a monthly dynamic treatment of production and financial activities over a long-ter

5. Simulated multipolarized MAPSAR images to distinguish agricultural crops
Many researchers have shown the potential of Synthetic Aperture Radar (SAR) images for agricultural applications, particularly for monitoring regions with limitations in terms of acquiring cloud free optical images. Recently, Brazil and Germany began a feasibility study on the construction of an orbital L-band SAR sensor referred to as MAPSAR (Multi-Applicat

6. Incorporação de energia na vida útil de uma colhedora autopropelida de cana-de-açúcar / Energy embodiment in life cycle of a self-propelled sugarcane harvester
The energy subject is one of the main challenges of 21st century. The geopolitical and environment aspects, they are concern sources to the current economic model. Brazil presents advantages in comparison to the world due to the use of renewable energy. Since 2007, products from the sugarcane have assumed the first place as a renewable source in the Brazilia

7. Tratamento e reuso do efluente de biodigestores no processo de biodigestão anaeróbia da cama de frango / Treatment and reuse of efluent of digesters in the anaerobic digestion of poultry litter
The anaerobic digestion process contributes as a method of treating poultry litter and energy generation. However, its applicability may cause some counter-intuitive, requiring for dilution to provide a suitable environment for microorganisms active in the anaerobic process. This dilution increases volume and difficulty of disposal of effluent. Thus, the obj

10. Reúso de efluente de esgoto sanitário anaeróbio e nitrificado em irrigação de roseiras / Reuse of anaerobic and nitrified wastewater effluents for irrigation of roses
Wastewater secondary treatment plants effluent may contain, yet, nutrients in amounts harmful to the environment. These effluents discharging can cause eutrophication in receiving waters, making it unsuitable for intended uses, such as provision for human consumption, leisure activities, etc. Besides the problem of eutrophication, there is the difficulty to

11. Zoneamento agroclimático da Jatropha curcas L. como subsídio ao desenvolvimento da cultura no Brasil visando à produção de biodiesel / Agroclimatic zoning of Jatropha curcas L. as a subside for the crop development in Brazil aiming the biodiesel production
No Brasil as pesquisas com Jatropha curcas L. foram impulsionadas a partir do marco regulatório do Programa Nacional de Produção e Uso do Biodiesel de 2004, em virtude da necessidade de substituição de matéria prima para fins energéticos. Por ser uma cultura recente no Brasil, ainda não existem pesquisas que definam a sua viabilidade e o sistema de c
