| This study was conducted to measure the effects of the timing of nitrogen fertilization (NF) on soil N-NH4+ and N-NO3-, macronutrient contents in the leaves and grains, and the grain yield of super early genotypes (SEG) of common bean. Field experiments were performed for four growing seasons in an Oxisol soil in Santo Antônio de Goiás, Brazil, using a randomized block experimental design in a split plot scheme. The plots were planted with common bean SEG, and the subplots were the NF timings, including a treatment without N fertilization. The available soil N with improved fertility and medium to high levels of organic matter were enough to meet the N demands of the common bean crop in order to achieve yields of up to 3,000 kg ha-1. Fertilization with N,... |

| The development process which humanity passed through favored a series of conquests, reflected in the better quality of life and longevity, however, it also provoked upsets and severe transformation in the environment and in the human food security. Such process is driving the ecosystems to be homogeneous, and, therefore, the nutrients' supply, via nourishment. To change this panorama, the present work discusses the gains of incorporating the stonemeal technique as a strategic alternative to give back the essential fertile characteristics to the soils. This technology has the function of facilitating the rejuvenation of the soils and increasing the availability of the necessary nutrients to the full development of the plants which is a basic input for the... |

| El maíz es el cultivo más importante del estado de Guerrero, por lo que, en el municipio de Tlalchapa, se realizó un análisis de los procesos de producción, de las condiciones socioeconómicas y tecnológicas, así como de las políticas gubernamentales de apoyo a la producción, todo ello para detectar las deficiencias existentes y proponer soluciones mediante las cuales los productores puedan mejorar la productividad y, por tanto, sus ingresos. El presente estudio se llevó a cabo en el periodo del 20 de julio al 14 de agosto de 2013, aplicando un cuestionario a los productores de maíz que siembran en el ciclo Primavera-Verano y posteriormente se utilizó la Matriz de Análisis de Política (MAP) para analizar la información obtenida. Los resultados de la... |

| En el sistema de cultivo Milpa Intercalada con Árboles Frutales (MIAF) más pobre en organismos del suelo y de menores contenidos de nutrientes para los cultivos, seleccionado mediante caracterización biológica y fisicoquímica de 8 MIAF ubicados en Huejotzingo-Chiautzingo, Pue. y en San Jerónimo Tecoatl, Oaxaca, se realizó un experimento de campo en Chiautzingo, empleando técnicas de bioestimulación (aplicación de enmiendas orgánicas: alfalfa cortada de la misma parcela, chícharo cultivado in situ y estiércol de vacuno) y de bioaumentación (inoculación de las lombrices de tierra: Lumbricus rubellus Hoffmeister, 1843 y Aporrectodea trapezoides Dugès, 1828, epigea y endógea, respectivamente), sobre el suelo cultivado con árboles de durazno, para evaluar sus... |

| Competing claims on natural resources become increasingly acute, with the poor being most vulnerable to adverse outcomes of such competition. A major challenge for science and policy is to progress from facilitating univocal use to guiding stakeholders in dealing with potentially conflicting uses of natural resources. The development of novel, more equitable, management options that reduce rural poverty is key to achieving sustainable use of natural resources and the resolution of conflicts over them. Here, we describe an interdisciplinary and interactive approach for: (i) the understanding of competing claims and stakeholder objectives; (ii) the identification of alternative resource use options, and (iii) the scientific support to negotiation processes... |

| Serious methodological and policy hurdles constrain effective natural resource management that alleviates poverty while protecting environmental services in tropical watersheds. We review the development of an approach that integrates biodiversity conservation with agroforestry development through the active involvement of communities and their local governments near the Kitanglad Range Natural Park in the Manupali watershed, central Mindanao, the Philippines. Agroforestry innovations were developed to suit the biophysical and socioeconomic conditions of the buffer zone. These included practices for tree farming and conservation farming for annual cropping on slopes. Institutional innovations improved resource management, resulting in an effective social... |

| Swidden agriculture, or shifting cultivation, is variously viewed as a great environmental threat or a sustainable system of land use. In Laos, swidden has long been considered the primary driver of forest loss nationwide, but the assessment is based exclusively on studies from the north of country, where deforestation is most severe. National policies to control swidden have percolated down to management of one of the largest nature reserves in the region, Nakai-Nam Theun National Protected Area (NNT NPA) in the Annamite Mountains of central Laos. In NNT NPA, swidden’s presumed unsustainability and deleterious impact on forest cover is an untested assumption. We tested it by methods of historical ecology, tracing the patterns of NNT’s... |

| Abstract This paper draws on the importance of science-based agriculture in order to throw light on the way scientific achievements are at the basis of modern civilization. An overview of literature on plant biotechnology innovations and the need to steer agriculture towards sustainability introduces a series of perspectives on how plant biotech can contribute to the major challenge of feeding our super population with enough nutritious food without further compromise of the environment. The paper argues that science alone will not solve problems. Three major forces - science, the economy and society - shape our modern world. There is a need for a new social contract to harmonize these forces. The deployment of the technologies must be done on the basis of... |

| Com ciência e tecnologia, a Amazônia Legal vem se transformando, nos últimos anos, em um grande polo de produção mundial. Na região da Amazônia Legal, o avanço de cultivos de grãos como soja, arroz, algodão e milho, além de espécies como dendezeiros, cacaueiros, cafeeiros, cupuaçuzeiros, açaizeiros, castanheiras, laranjeiras, coqueiros, jambus e urucuzeiros e até reflorestamento têm ocorrido pela mudança de perfil da "pecuarização" para a "agriculturização". Tudo com o emprego de ciência e tecnologia, além de respeito ao meio ambiente. |

| As raças bovinas introduzidas pelos Portugueses e Espanhóis durante a colonização do Brasil caracterizam-se pela rusticidade, adaptabilidade, resistência e constituem um importante recurso genético para a bovinocultura. A partir das raças ibéricas sugiram as raças locais brasileiras, que no século XXI estão limitadas a cinco raças geneticamente distintas, distribuídas nas diferentes regiões do país: Caracu e Mocho Nacional no Sudeste, Crioulo Lageano no Sul, Curraleiro Pé-Duro no Norte, Nordeste e Centro-Oeste e Bovino Pantaneiro no Centro-Oeste. A manutenção de tais raças, além de garantir a conservação de patrimônio genético valioso, pode atender demandas de mercados especializados. No Brasil, entre as limitações para a conservação da diversidade... |

| Com o objetivo de levar os pequenos agricultores do Acre a cultivarem pequenas áreas de tal forma que obtenham resultados econômicamente satisfatórios, matendo a sustentabilidade do agroecossistema, há necessidade de se obter um maior conhecimento das consequências da adoção de sistemas agroflorestais, considerados adequados para a região, quanto a vários aspectos, incluindo-se os de ordem fitossanitária. O presente estudo teve por objetivo direcionar as observações, quanto ao comportamento das pragas das culturas de arroz, milho e feijão, quando utilizadas como componentes de um modelo de sistema agroflorestal. Neste modelo, durante o primeiro ano de cultivo das culturas anuais ocorreu um incremento populacional consequentemente de danos, das principais -... |
