1. Soil conservation management with cover crops: effects on critical energy levels, release and dispersion of aggregates
ABSTRACT The normalized dispersion index (NDI) and the b/a index are commonly used to express the stability of aggregates measured by ultrasound. However, few studies have used the critical energy (CE) extracted from modeling to explain the effects of soil use and management on soil aggregation. The objective of this study was to evaluate the influence of so

2. Forage production and quality of tropical forage legumes submitted to shading
RESUMO: Encontrar espécies tolerantes ao sombreamento é essencial para o sucesso dos sistemas silvipastoris, cada vez mais frequentes nos últimos anos. Em se tratando de leguminosas, que possuem potencial de fixação biológica de nitrogênio, há uma grande carência de conhecimento em ambientes sombreados. Objetivou-se avaliar o cultivo de quatro legu

3. Estimating Yield Losses in Soybean Due to Sourgrass Interference
RESUMO: O manejo do capim-amargoso se destaca como um dos principais desafios enfrentados pelos sojicultores brasileiros. Características relacionadas a sua biologia e ecologia, associado à ampla distribuição de biótipos resistentes ao glyphosate, tornam essa planta daninha uma espécie de difícil controle. Objetivou-se com este trabalho avaliar a inte

4. Dry matter production and chemical composition of tropical forage legumes under different shading levels
ABSTRACT. This study aimed to evaluate the shading influence on production and qualitative traits of four tropical forage legumes (calopo, puero, archer and perennial soybean). Legumes were cultivated under levels of artificial shading (0; 30; 50 and 70%) from January 2006 to June 2007. Dry matter production (DM), crude protein (CP), neutral detergent fiber

5. Water Erosion on an Oxisol under Integrated Crop-Forest Systems in a Transitional Area between the Amazon and Cerrado Biomes
ABSTRACT Water erosion is one of the main factors driving soil degradation, which has large economic and environmental impacts. Agricultural production systems that are able to provide soil and water conservation are of crucial importance in achieving more sustainable use of natural resources, such as soil and water. The aim of this study was to evaluate soi

6. Energy embodiment in Brazilian agriculture: an overview of 23 crops
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a v

7. Classes of secondary metabolites identified in three legume species
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the

8. Chemical composition and ruminal degradation kinetics of crude protein and amino acids, and intestinal digestibility of amino acids from tropical forages
The objective of this research was to determine the chemical composition and ruminal degradation of the crude protein (CP), total and individual amino acids of leaves from tropical forages: perennial soybean (Neonotonia wightii), cassava (Manihot esculenta), leucaena (Leucaena leucocephala) and ramie (Boehmeria nivea), and to estimate the intestinal digestib

10. Cálcio e boro para soja-perene: características anatômicas e agronômicas e concentração de nutrientes / Calcium and boron for perennial soybean: anatomical and agronomic characteristics and nutrient concentrations
Forage legumes have been mixed with grasses and contributed to improve the sustainability of the soil- plant- animal system. Perennnial soybean (Neonotonia wightii) is one forage legume well adapted to the tropical areas. Calcium and boron have resulted in benefits for plant development, particularly in legume species. This study was set with the objectives

11. Biologia e manejo da planta daninha Borreria densiflora DC. / Biology and management of the weed Borreria densiflora DC.
The weed vassourinha-de-botao (Borreria densiflora DC.) has been presenting increase in its infestation in areas cultivated with sugarcane and soybean, respectively in Maranhao and Goias states and north of Tocantins state, Brazil. Field observations have reported the control deficiency of this species, when it occurs in advanced growth stage. Thus, this res

12. Origins, colonization, and lineage recombination in a widespread perennial soybean polyploid complex
Polyploidy is a dominant feature of flowering plant genomes, including those of many important crop species, implying that polyploidy confers evolutionary advantages on plant species. Recent molecular studies suggest that polyploids often originate many times from the same progenitor diploids. For this to provide a broader genetic base for a polyploid specie
