| Abstract Conservation management systems that have intended to prevent wear or soil degradation have been widespread in agriculture. The study was conducted in Site São Luiz at Simonsen district, Votuporanga, São Paulo State, in order to evaluate the chemical and physical changes in an area with agrosilvopastoral system and deployed with three soil management (treatments): Full (conventional tillage, liming and application of gypsum, phosphate and potassium); intermediate (no tillage, liming and application of gypsum at surface) and basic (no tillage and surface liming). The soil was managed in July 2009 and the planting of eucalyptus was realized in January 2010, on the terraces. Between the terraces it was cropped maize intercropped with Urochloa... |

| ABSTRACT The objective with this study was to calculate the total cost of maize production and beef cattle in permanent pasture activities in separate production systems (conventional) and integrated systems (maize production plus beef cattle), as well as to verify economic gains explained by the economy of scope. The first step for the development of the research was to obtain field experimental data. Six experimental treatments were studied: corn grain production, beef cattle in permanent pasture, and four integrated systems based on different crop and pasture sowings. The second step consisted in the collection, calculation, and allocation of variable and fixed costs to estimate costs of production in the systems. The crop-livestock integration showed... |

| Os sistemas integrados de produção lavoura-pecuária (SIPAs) em associação ao sistema de semeadura direta, sofrem ação do pisoteio animal ou do tráfego intenso de máquinas agrícolas, podendo resultar em alterações nas propriedades físicas do solo. O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada e manejos das forrageiras tropicais nas propriedades físicas do solo. O experimento foi realizado entre outubro de 2017 e janeiro de 2020, em Marechal Cândido Rondon – PR, em blocos ao acaso, com parcelas sub-subdivididas com uma testemunha adicional e quatro repetições. As parcelas foram constituídas por duas espécies forrageiras consorciadas com o milho: Urochloa brizantha e Magathyrsus maximum, mais a testemunha adicional (milho solteiro).... |

| The former extensive polyculture systems of marine fish farming, are today replaced mainly by intensive monoculture systems (salmon, shrimp). These systems, multiplied in the same coastal zone, can present a significant environmental impact. To treat and value fish farming effluents, new integrated systems were constructed and tested to different scales. Some examples of land- and seabased systems around the world are presented, in particular the European project of innovation "Genesis" in which several French public and private, national and regional organisations are participants (IFREMER, Regional Centre of Experiment and Aquacultural Applications in Poitou- Charentes, IDEE). Recommendations are supplied to promote the development of the integrated fish... |

| O objetivo deste trabalho foi avaliar índices de conforto térmico em sistemas de integração lavoura-pecuária-floresta, com eucalipto em arranjos de 14x2m (ILPF-1) e de 22x2m (ILPF-2) e árvores nativas dispersas com 5 árvores/ha-1 (ILPF-3), no Município de Campo Grande, Mato Grosso do Sul. O experimento foi conduzido na Embrapa Gado de Corte, em Campo Grande, MS, de julho a setembro de 2013. As avaliações foram realizadas mensalmente, em quatro dias consecutivos, em três horários (09h00, 12h00 e 15h00; GMT -04h00). Foram determinadas a temperatura do ar (°C), temperatura de globo negro (°C), temperatura de bulbo úmido (°C), umidade relativa do ar (%) e velocidade do vento (m s-1). Foram calculados o Índice de Temperatura e Umidade (ITU), Índice de... |

| Abstract: The objective of this work was to evaluate the performance of crossbred steers post-weaned in an integrated crop-livestock system (ICL) and finished in a feedlot, fed either a high-level concentrate diet or whole corn with no roughage. Weaned calves of two breed groups - ½ Angus × ½ Nellore, and ½ Charolais × ¼ Angus × ¼ Nellore - were allotted in a completely randomized experimental design (CRD). During the rainy season, the ½ Angus × ½ Nellore animals showed a higher performance than the ½ Charolais × ¼ Angus ×¼ Nellore ones, with 0.748 and 0.490 kg average daily gain, respectively. The productivity in the post-weaning period was 926 kg ha-1 body weight in a 11-month period, in the ICL system. Subsequently, the animals were confined and fed... |
