1. Phytodesalination of a moderately saline soil combined with two inorganic amendments
ABSTRACT The shortage of water and the increasing salinity are the main limiting environmental factors that directly affect the establishment and the development of crops. In this research, phytodesalination capacity of Sesuvium verrucosum was evaluated alone and in combination with agricultural gypsum (CaSO4·2H2O) and Polisul-C, in order to remedy a modera

2. ESTIMATION OF MAIZE BIOMASS USING UNMANNED AERIAL VEHICLES
ABSTRACT Unmanned aerial vehicles (UAVs) are a promising tool for technology development and transfer and for the economic success of the agricultural sector. The objective of this study is to assess the validity of biomass estimation in a commercial maize plantation using aerial images obtained by a UAV. The proposed methodology involved analyzing images ac

3. Relative Competitiveness of Common Bean Cultivars in Coexistence with Volunteer Corn
RESUMO: Objetivou-se com este estudo avaliar a competitividade relativa de dois cultivares de feijão-comum em convivência com milho voluntário emergindo em diferentes épocas, em diferentes proporções de plantas na associação. Primeiramente, tanto para o feijão como para o milho voluntário, determinou-se a população de plantas em que a produção

4. Partitioning and Modeling of Biomass in Caatinga Legume Seedlings in Different Water Conditions
ABSTRACT The accumulation of dry biomass, its partitioning and the adjustment of equations were assessed for the initial growth of Piptadenia stipulacea (Benth) Ducke and Anadenanthera colubrina (Vell.) Brenan under water availability variation. The experiment was conducted in pots arranged in a completely randomized design with three replicates. Water condi

5. Inventory of Organic Carbon in a Pterogyne nitens Tul. Plantation in Southwest Bahia, Brazil
ABSTRACT Carbon binding capacity varies between forest plantations, mainly in terms of species and climate and soil conditions. The objective of this study was to estimate the amount of organic carbon stored in aerial tree biomass in the litter and soil of a homogeneous planting of Pterogyne nitens Tul. located in the Southwest Bahia region of Brazil. The wo

6. Aerial biomass allometric models for Prosopis affinis Spreng. in native Espinal forests of Argentina
RESUMO A estimativa do carbono armazenado nos ecossistemas florestais requer ferramentas precisas para prever a biomassa. Objetivou-se nesse estudo determinar a biomassa aérea individual de Prosopis affinis e sua distribuição por componente; desenvolver modelos alométricos para prever a biomassa, e estimar os fatores de expansão da biomassa (FEB) em flo

7. Arbuscular mycorrhizal fungi and auxin associated with microelements in the development of cuttings of Varronia leucocephala
RESUMO Varronia leucocephala é uma planta utilizada pela população para fins terapêuticos. Um dos maiores problemas para produção de mudas dessa espécie é o baixo percentual de enraizamento. Objetivou-se estabelecer um protocolo de enraizamento de estacas de V. leucocephala utilizando fitorreguladores e microelementos associados com fungos micorrízi

8. Potassium Fertilization of Eucalyptus in an Entisol in Low-Elevation Cerrado
ABSTRACT Potassium (K) is one of the most highly accumulating nutrients in Eucalyptus and, consequently, is heavily exported by the harvesting of wood. Moreover, its availability in the soil in most Brazilian plantation areas is very low, especially in the regions of the Cerrado biome, which has soils with low natural fertility and marked water deficits, imp

9. Benefits Associated with the Interaction of Endophytic Bacteria and Plants
ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria th

10. Effects of habitat heterogeneity on epiedaphic Collembola (Arthropoda: Hexapoda) in a semiarid ecosystem in Northeast Brazil
ABSTRACT The spatial distribution of abiotic resources and environmental conditions can vary at small scales within terrestrial ecosystems, influencing the composition of soil fauna. Epiedaphic springtails (Collembola) of a semiarid Caatinga ecosystem were studied to determine if factors related to vegetation structure, such as species richness, aerial bioma

11. Potentiality of Melastoma malabathricum as Phytoremediators of soil contaminated with sewage sludge
ABSTRACT: Heavy metal pollution of the soil environment has become a major source of concern and continues to pose serious health problems to both humans and ecological systems worldwide. Phytoremediation is a biological treatment whereby plants are used to remove pollutant from the environment. An experiment was conducted to evaluate the potential of Melast

12. Management techniques for the control of Melinis minutiflora P. Beauv. (molasses grass): ten years of research on an invasive grass species in the Brazilian Cerrado
ABSTRACT The invasion of exotic species is considered to be a major threat to the preservation of biodiversity. In the Parque Nacional de Brasília (National Park of Brasília), the invasive Melinis minutiflora (molasses grass) occupies more than 10 % of the area of the park. The present, long-term, study compared two treatments of exposure to molasses grass
