1. Use of organic substrates on the quality of watermelon seedlings
RESUMO Melancia (Citrullus lanatus) é uma planta frutífera, ramadora, cultivada no México, gerando emprego e divisas para o país. Há necessidade de pesquisar substratos orgânicos locais ideais para substituir a turfa como meio de cultura visando produção de mudas de melancia de boa qualidade com baixo custo. Portanto, avaliou-se as propriedades físi

2. Root-knot nematode, Meloidogyne javanica, in response to soil fertilization
Resumo Nematoides-das-galhas das raízes (RKNs) Meloidogyne spp. causam perdas consideráveis na produção de hortaliças em todo o mundo. Embora o uso de nematicidas químicos seja um dos principais meios de controle de RKNs, a dependência nesses nematicidas está associada aos altos custos e impactos negativos à saúde humana e ao meio ambiente. No pres

3. Composition and mineralization of organic compost derived from composting of fruit and vegetable waste
ABSTRACT Fruit and vegetable waste can be used for the production of organic compost, which when mineralized can increase the availability of nitrogen. The objectives of this study were: (a) to produce compost from different ratios of fruit and vegetable waste, rice husk and poultry manure that meets the legislation on organic fertilizers and (b) to assess t

4. Growth of tomato seedlings in substrates containing a nanocomposite hydrogel with calcium montmorillonite (NC-MMt)
RESUMO O uso correto de hidrogéis em determinadas situações pode aumentar as taxas de sobrevivência das plântulas, seu crescimento e a capacidade de retenção de água do meio de cultivo. Uma técnica para a produção de um hidrogel nanocompósito usando montmorilonita de cálcio (NC-MMt) foi desenvolvida recentemente. No entanto, resultados da pesqui

5. Epidermal morphology of the cordaitalean leaf Noeggerathiopsis brasiliensis nom. nov. from the southern Paraná Basin (Lower Permian, Rio Bonito Formation) and paleoenvironmental considerations
Abstract A Brazilian cordaitalean leaf is reassigned and redescribed based on cuticular analysis. The new name Noeggerathiopsis brasiliensis is erected as a replacement for Rufloria gondwanensis Guerra-Sommer. The leaf adpressions come from a tonstein layer within a Sakmarian coal seam of the Faxinal Coalfield, southern Paraná Basin, Brazil (U-Pb SHRIMP mea

6. Vermicompost and biochar substrates can reduce nutrients leachates on containerized ornamental plant production
RESUMO A produção de plantas ornamentais em contêineres está enfrentando vários desafios ambientais. Um deles é substituir os substratos amplamente utilizados, mas com sustentabilidade questionável, baseados em turfa, e outro é evitar a contaminação da água por produtos químicos lixiviados do viveiro. Verificou-se que as plantas de petúnia e ger

7. Poultry Litter for the Production and Quality of Enterolobium contortisiliquum Vell. Seedlings
ABSTRACT The objective of this work was to determine the efficiency of poultry litter ratios added to the commercial substrate and to peat in the growth and quality of Enterolobium contortisiliquum seedlings. The design was completely randomized, with 10 replications, in a 2 × 5 factorial arrangement with two substrates (peat and commercial substrate) and

8. Paleoenvironmental Characterization of a High-Mountain Environment in the Atlantic Forest in Southeastern Brazil
ABSTRACT: Records of changes in the phytosociological structure of vegetation can be observed more clearly in soils that have more significant accumulation of organic matter, like those occurring in high-mountain environments. The aim of this study was to characterize soils formed in high-mountain environments in the Itatiaia National Park (INP), state of Ri

9. Elastic and Osmotic Adjustment of Talipariti elatum (Sw) Frixell Grown in Organic Substrates
ABSTRACT The aim of the present study was to evaluate the water response of Talipariti elatum cultivated in different substrates. Sugarcane straw, peat, biochar and mixtures of sugarcane straw and biochar, and peat and biochar were used. The physical properties of each substrate and the water parameters of the species were determined based on the pressure-v

10. Symbiotic and agronomic efficiency of new cowpea rhizobia from Brazilian Semi-Arid
ABSTRACT Cowpea is a very important crop to Brazilian Semi-Arid mainly small family-based farmers. Rhizobia inoculation is a practice, easy to use, and cheap technology that increases cowpea productivity. The aim of this study was to evaluate the efficiency of two new rhizobia isolates in greenhouse and field as well as classify them taxonomically. To bacter

11. Soil Fertility and Electrical Conductivity Affected by Organic Waste Rates and Nutrient Inputs
ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation,

12. Symbiotic potential and survival of native rhizobia kept on different carriers
Native rhizobia are ideal for use as commercial legume inoculants. The characteristics of the carrier used to store the inoculants are important for the survival and symbiotic potential of the rhizobia. The objective of this study was to investigate the effects of peat (PEAT), perlite sugarcane bagasse (PSB), carboxymethyl cellulose plus starch (CMCS), an
