1. Weed Interference in the Establishment of Urochloa ruziziensis
RESUMO: Objetivou-se neste trabalho estudar a relação de interferência de plantas daninhas sobre a morfogênese, produtividade e potencial de produção de gases de efeito estufa de Urochloa ruziziensis em condições de renovação de pastagem. O delineamento experimental foi em blocos ao acaso, com os tratamentos constando de sete períodos de convivên

2. Intercropping Between Corn and Urochloa brizantha Managed with Mesotrione Underdoses
RESUMO: Consórcios entre a cultura do milho e espécies forrageiras são comumente utilizados para a implantação ou renovação de pastagens. O uso de doses reduzidas de herbicidas seletivos ao milho tem facilitado a convivência pela redução da competitividade das espécies forrageiras. Objetivou-se avaliar nesta pesquisa os efeitos de subdoses de meso

3. 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

4. Panicum maximum cv. Aries Establishment under Weed Interference with Levels of Light Interception and Nitrogen Fertilization
RESUMO: O objetivo deste trabalho foi avaliar o estabelecimento da pastagem de Panicum maximum cv. Áries em área de proteção ambiental sob influência de níveis variados de interação interespecífica exercidos pela comunidade de plantas daninhas. O experimento foi executado após semeadura da forrageira, delineado em blocos casualizados, no esquema fa

5. Effect of Brachiaria Grass on Vegetative Development of Teak
ABSTRACT Invasive plants are a limiting factor for the establishment of planted teak (Tectona grandis L.f.) forests, especially because most of them are planted on Urochloa decumbens Stapf degraded pastures. This study evaluated initial teak development applying different control alternatives for U. decumbens . Treatments were no weed control (T1), continuo

6. Survival and growth of tree seedlings as a function of seed size in a gallery forest under restoration
ABSTRACT Seed size is commonly related to higher rates of emergence and survival, and biomass of seedlings when introduced by direct seeding. However, few studies have evaluated whether this relationship persists when species are reintroduced as seedlings or if this effect persists after seed reserves decline. This study evaluated the effect of seed size (ma

7. Land Use and Changes in Soil Morphology and Physical-Chemical Properties in Southern Amazon
ABSTRACT Many Amazonian farmers use the slash-and-burn method rather than fertilization for crop production. The aim of the present study was to evaluate changes in the morphological, physical, and chemical properties of naturally fertile Inceptisols after conversion from native forest to different uses in southern Amazonia, Brazil. Land covered by dense nat

8. Population structure and fruit availability of the babassu palm ( Attalea speciosa Mart. ex Spreng) in human-dominated landscapes of the Northeast Region of Brazil
ABSTRACT We studied the population structure and fruit availability of the babassu palm, Attalea speciosa, in three human-dominated landscapes located near a rural community in the region of Araripe, in the Northeast Region of Brazil, that were under intense fruit harvest. Fifty 10 x 10 m plots were randomly established in each of the three landscapes, and a

9. Biological Properties and Organic Matter Dynamics of Soil in Pasture and Natural Regeneration Areas in the Atlantic Forest Biome
ABSTRACT The removal of original vegetation for crops and pasture production and then followed by natural regeneration is a standard practice in the Atlantic Forest, which has produced patches with different degrees of degradation and regeneration across the landscape. The aim of this study was to evaluate the effects of replacement of native forest by pastu

10. Soil Properties and Plant Biomass Production in Natural Rangeland Management Systems
ABSTRACT Improper management of rangelands can cause land degradation and reduce the economic efficiency of livestock activity. The aim of this study was to evaluate soil properties and quantify plant biomass production in four natural rangeland management systems in the Santa Catarina Plateau (Planalto Catarinense) of Brazil. The treatments, which included

11. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

12. Development of maize and palisadegrass plants cultivated in intercrop under water deficit
The objective of this work was to evaluate the development and productive traits of palisadegrass single cultivated or intercropped with corn, in addition to corn intercropped with pasture, under water deficit at different development stages of the plants. It was used a complete block experimental design with split plots and three replicates. Periods of wate
