1. NET PRIMARY PRODUCTIVITY OF A MOUNTAIN FOREST ECOSYSTEM AS AFFECTED BY CLIMATE AND TOPOGRAPHY
ABSTRACT Response of terrestrial ecosystems to changing climate has become an issue of central importance for land managers and policymakers. Climate extremes and trends have a strong control on productivity of semi-arid mountain ecosystems. Located in a transition zone from continental type climate to relatively mild Black Sea type climate in Turkey, the Il

2. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

3. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

4. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

6. AGRONOMIC PERFORMANCE AND BIOLOGICAL EFFICIENCY OF KALE INTERCROPPED WITH SPICE SPECIES
RESUMO A consorciação de culturas é uma estratégia de manejo que visa a sustentabilidade dos agrossistemas, sendo adequada à produção de hortaliças. A couve é preponderantemente manejada sob cultivo solteiro, mas observações de campo tem indicado que a cultura tem potencial produtivo satisfatório quando cultivada em consórcio com outras hortali�

8. Modelagem do uso da Terra e Efeitos de Mudanças na Produtividade Agrícola entre 2008 e 2015
Resumo O artigo apresenta os resultados dos efeitos sistêmicos da mudança no padrão da produtividade agrícola entre 2008 e 2015. Para isso foi utilizado um modelo de equilíbrio geral computável (EGC) com especificação detalhada do uso da terra. Tal análise representa avanços no sentido de contribuir tanto para a modelagem econômica com uso da terr

9. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

10. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

11. OUTDOOR CULTIVATION OF Scenedesmus obliquus BR003 IN STIRRED TANKS BY AIRLIFT
ABSTRACT: The use of microalgae as a source of raw material for biofuel production has been highly targeted. Compared to other biological options for the capture and use of CO2, microalgae crops have the following advantages: high productivity, lack of competition with feed and food-based products, use of unproductive and non-arable land, and allowance of th

12. Tree legumes: an underexploited resource in warm-climate silvopastures
ABSTRACT Tree legumes are an underexploited resource in warm-climate silvopastures. Perceived benefits of tree legumes include provisioning (browse/mast, timber, fuel, human food, natural medicines, and ornamentals), regulating (C sequestration, greenhouse gas mitigation, soil erosion control and riparian buffers, shade, windbreaks, and habitat for pollinato
