1. Hole spacing in soybean hill drop sowing1
ABSTRACT The aim of this study was to evaluate the development, yield and its components of soybean sown in hill drop method with variation in hole spacing, compared to the conventional sowing method in lines. The experiment was conducted in a randomized block design, with six treatments and four replications, using the variety M7739 RR IPRO with four plans

2. Growth and quality of Brazilian pine tree seedlings as affected by container type and volume
Resumo Araucaria angustifolia (Bert.) O. Kuntze (Araucariaceae), popularmente conhecida como araucária e pinheiro brasileiro, pode ser cultivada em função de suas sementes comestíveis (pinhões), propriedades medicinais e atributos ornamentais. O objetivo foi avaliar o crescimento de parte aérea e radicular e a qualidade geral de mudas de A. angustifoli

3. BIOLOGICAL FERTILIZER AND COVER PLANTS ON SOIL ATTRIBUTES AND MAIZE YIELD
RESUMO O milho é uma importante cultura para a economia brasileira, porém, é produzido em sistema de monocultura, e por isso, torna-se necessário o uso de práticas conservacionistas de manejo do solo que favoreçam o desenvolvimento da cultura. O objetivo deste estudo foi avaliar os efeitos da adubação biológica e plantas de cobertura nas propriedade

4. Sowing date and fungicide application in the agronomic performance of oleaginous brassica for the biodiesel production
ABSTRACT This work aims to evaluate the agronomic performance of crambe and juncea canola, sowed in the summer and winter season intervals with and without fungicide application. The cultivars used were FMS Brilhante and Terola 25A85 for crambe and juncea canola, respectively. The experimental design was randomized blocks in split plots, in which the plots w

5. Seed position and influences on Caesalpinia pulcherrima germination and reserve proteins
Resumo Caesalpinia pulcherrima apresenta diversos usos no mundo, mas há grande disparidade de germinação no momento da produção de mudas, sendo esse fator talvez atribuído à posição que a semente ocupa no fruto. Assim, o objetivo deste trabalho foi avaliar aspectos germinativos e concentrações de proteínas de reserva em sementes de C. pulcherrima

6. [PROVISIONAL] Mitochondrial genomes of genus Atta (Formicidae: Myrmicinae) reveal high gene organization and giant intergenic spacers
Abstract The ants of the genus Atta are considered an important pest to agriculture in Latin América, although, Atta species are important contributors to ecosystem functions in the various habitats in which they occur. Next-generation sequencing product millions or billions of short reads, however, is necessary to applied methods for assembly of the genome

7. Nitrogen recovery efficiency for corn intercropped with palisade grass
ABSTRACT Intercropping corn and palisade grass is a technique to increase straw production, soil C contents, nutrient cycling and crop yield. However, concerns arise from nitrogen (N) uptake by the intercropping crop causing reduction in the yield of the corn. Our objective was to evaluate N recovery efficiency (NRE), and the N dynamics in the soil-plant sys

8. Carbon sequestration and greenhouse gases emissions in soil under sewage sludge residual effects
The large volume of sewage sludge (SS) generated with high carbon (C) and nutrient content suggests that its agricultural use may represent an important alternative to soil carbon sequestration and provides a potential substitute for synthetic fertilizers. However, emissions of CH4 and N2O could neutralize benefits with increases in soil C or saving fertiliz

9. Inoculum potential of Fusarium verticillioides and performance of maize seeds
This work was conducted to evaluate the effect of Fusarium verticillioides on the early stage development of maize seedling/plants, considering different inoculum potentials of this fungus in seeds, under controlled conditions. To obtain seeds with different inoculum potentials of that fungus, the osmo-priming technique as referred to in literature was used.

10. DECOMPOSIÇÃO DE RESÍDUOS CULTURAIS DE PLANTAS DE COBERTURA DE SOLO E EMISSÕES DE ÓXIDO NITROSO / COVER CROPS RESIDUES DECOMPOSITION AND NITROUS OXIDE EMISSIONS
The inclusion of summer cover crops (SCC) in the no-till system is an interesting alternative to promote the addition of elevated quantities of plant biomass and nitrogen (N) to the soil. The C and N dynamics during the SCC residue decomposition can control the nitrous oxide (N2O) fluxes to the atmosphere. This study was carried out to quantify the SCC resid

11. Reprodução, distribuição e padrões de co-ocorrência em uma comunidade de palmeiras na Amazônia central: Uma abordagem teórica e experimental / Main drivers controlling reproduction, distribution and co-occurrence patterns in a palm community in a terra firme Forest at central Amazonia: A theoretical and experimental approach
One of the main concerns of community ecology is to determine which factors affect species distribution. Starting from the premise that fruit production is the last step of true establishment, we match environmental gradients and the experimental approaches with help from phylogenetic tools to bring light into the mechanisms influencing palm distribution pat

12. Dinâmica da pastagem nativa submetida a regimes de distúrbios e sobressemeada com Eragrostis plana nees / Dynamics of native grassland submitted to disturbance regimes and sowed with Eragrostis plana nees
Objetivou-se com este trabalho determinar o efeito de regimes de distúrbio sobre os padrões espaciais de cobertura das espécies presentes nas pastagens naturais, atributos funcionais médios das comunidades e a resistência destas à invasão por Eragrostis plana Nees (capim-annoni). O experimento avaliado foi conduzido durante 6 anos (2004-2010), em Dom
