1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

2. Competitive interaction and economic injury level of Urochloa plantaginea in corn hybrids
RESUMO A identificação da habilidade competitiva de híbridos de milho e do nível de dano econômico (NDE) ocasionado pelo papuã (Urochloa plantaginea) torna-se importante para a adoção do manejo integrado dessa planta daninha. Diante disso, objetivou-se com este trabalho avaliar a interferência e o NDE de papuã infestante de híbridos de milho. Os t

3. Release of Phosphorus Forms from Cover Crop Residues in Agroecological No-Till Onion Production
ABSTRACT Cover crops grown alone or in association can take up different amounts of phosphorus (P) from the soil and accumulate it in different P-forms in plant tissue. Cover crop residues with a higher content of readily decomposed forms may release P more quickly for the next onion crop. The aim of this study was to evaluate the release of P forms from res

4. Cover Crops Effects on Soil Chemical Properties and Onion Yield
ABSTRACT Cover crops contribute to nutrient cycling and may improve soil chemical properties and, consequently, increase crop yield. The aim of this study was to evaluate cover crop residue decomposition and nutrient release, and the effects of these plants on soil chemical properties and on onion (Allium cepa L.) yield in a no-tillage system. The experiment

5. Densidade de semeadura e consÃrcio de braquiÃria e estilosantes visando à formaÃÃo de cobertura vegetal para a cultura da soja / Seeding density and consortium of brachiaria and stylosanthes aiming at vegetation cover to the soybean crop
The tillage efficiency is directly related to the management and choice of vegetation species prior to sowing the crop. In this context, this study examined the effect of brachiaria sowing densities (Brachiaria ruziziensis) (10; 15 and 20 kg ha-1), stylosanthes (Stylosanthes macrocephala and Stylosanthes capitata) (3; 4.5 e 6 kg ha-1) and consortium of these

6. Influence of edaphic variables on the floristic composition and structure of the tree-shrub vegetation in typical and rocky outcrop cerrado areas in Serra Negra, Goiás State, Brazil
The present study analyzed the influence of edaphic variables on the floristic compositions and structures of the arboreal and shrub vegetation of typical cerrado (TC) and rocky outcrop cerrado (RC) communities in the Serra Negra mountain range in Piranhas Municipality, Goiás State, Brazil. Ten 20×50m plots were established in each community, and all indiv

7. Effect of intercropping wheat with forage legumes on wheat production and ground cover.
The use of winter legumes in southern Brazil is hindered by the slow growth of these species during establishment exposing soil surface to erosion. Introduction of these species along with spring wheat (Triticum aestivum L.) was studied as a means of increasing ground cover during their initial establishment period, without reducing wheat grain yield. Two ex

8. Quantificação do crescimento radicular em perfil de solo.
RESUMO: O estudo do comportamento radicular facilita a compreensão da parte aérea da planta e do manejo do solo. O trabalho objetivou avaliar a concentração radicular através do programa Ambiente para visualização de Imagens (ENVI), em perfis culturais sob diferentes sistemas de manejo, na Embrapa Cerrados, Planaltina - DF. O experimento foi constitu�

9. Tratamento de sementes, densidade e método de semeadura de Brachiaria brizantha no consórcio milho e braquiária / Treatment of seed, density and sowing methods of Brachiaria brizantha intercropping maize and pasture
The integrated crop livestock farming system is an important training and renovation of degraded pastures. However, lack technical information about physiological and sanitary quality of the forage seeds and sowing methods have been suggested as causes of failure in some fields. This work aimed to evaluate the effects of treatment of seeds of Brachiaria briz

10. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

11. Desempenho de plantas de cobertura no controle da erosão hídrica no Sul de Minas Gerais / Performance of cover crops to control erosion in the South of Minas Gerais
The erosion initiates with the impact of the raindrop on the soil surface, causing the transport of sediment, nutrients and organic matter. To reduce this erosion, the use of conservation practices, such as proper management and planting of cover crops that reduce these losses, is essential. The objective of this study was to evaluate the potential of plant

12. Efeitos do pisoteio humano experimental sobre a vegetação em fragmentos de Floresta Pluvial Tropical Atlântica, São Paulo, Brasil / Experimental human trampling effect on the vegetation in fragments of the Atlantic Rain Forest, São Paulo, Brazil
The growing flow of visitors at natural areas, with the consequent pressure over natural resources caused an increase on concerns about the produced negative impacts. Recreation Ecology studies the impacts of recreational activities at visited environments, aiming to provide results which are useful for the management of these impacts. The effects of human t
