Por se tratar de uma atividade complexa, os estudos de viabilidade econômica de sistemas agroflorestais (SAFs) exigem maior esforço para avaliação. Dentre os motivos estão a maior quantidade de elementos a serem considerados, a necessidade de prever os efeitos das interações entre as diferentes espécies consorciadas e a dificuldade de valorar os benefícios ambientais do sistema. Dessa forma, o objetivo deste trabalho foi analisar e sintetizar os principais métodos de avaliação econômica descritos na literatura. Através dele é possível determinar quais itens devem ser computados na análise e como atribuir valores a eles para definir as principais receitas e custos do projeto. Ainda, podem ser traçados os principais métodos de análise econômica e de... |

The influence of the diet on the quality of buffalo (Bubalus bubalis) carcasses of crossbred Murrah and Mediterranean, concentrate fed on traditional (corn/soybean) or on agro-industrial residues (palm oil and coconut cakes) was studied. The animals were sacrificed in a slaughterhouse, and physical and physical-chemical analyses in the carcasses were carried out after 24 hours, and instrumental color and texture analyses of the Longissimus dorsi were carried out 48 hours after cooling. The animals supplemented with palm oil cake had better carcass conformation and fat trim, and differences (P<0.05) in the percentage of fat in the carcass fat thickness and coverage were observed. |

Neste trabalho esta sendo proposto o desenvolvimento de alternativas tecnologicas que permitam o manejo sustentado da vegetacao da caatinga, com o objetivo de evitar a degradacao ambiental e promover a recuperacao da produtividade agricola e pecuaria em niveis economicos e ecologicos. A manipulacao da vegetacao, atraves do raleamento, do rebaixamento, do raleamento-rebaixamento e do enriquecimento, pode aumentar a disponibilidade de forragem em ate 800% e a producao animal em ate 1500%. A sustentabilidade da producao agricola em condicoes tropicais sera obtida com sua fixacao, substituindo-se as praticas atuais de manejo da pecuaria, tais como o banco rocado. O manejo da vegetacao da caatinga com vistas a obtencao de produtos nao madereiro, ainda e... |

The aim of this study was to evaluate the effect of different crown diameters on the early growth of eucalyptus intercropped with Brachiaria decumbens in a silvopastoral system. The experiment was conducted in a B. decumbens established pasture, where hybrid eucalyptus urograndis (clone GG100) was planted, spaced 8 x 3 m. A randomized block design was used, with six replicates. Treatments consisted of five crown diameters (0.0, 1.0, 1.5, 2.0, and 3.0 m) surrounding the eucalyptus plants. Five weeding hoes were performed throughout the experiment, according to the different crown diameters, aiming to maintain the eucalyptus plants free from B. decumbens interference. At 90, 180, 270, and 360 DAP, the height and the diameter of the eucalyptus plants were... |

This study was carried out in order to characterize and evaluate the home gardens in Machipanda, Manica Province (Mozambique). Interviews were conducted at 37 heads of households. The results were analyzed using descriptive statistics. To facilitate information understanding and analysis, they were grouped into a SWOT Matrix, so that its components: strengths, weaknesses, opportunities and threats in relation to the backyards studied, were highlighted. The backyards were mostly irregular, with an area ranging from 400-5,000 m2 with average of 770.27 m2. In the home gardens it was found that 90% practiced agrossilvipastoril system and 10% practiced agroforestry system. Twenty-four tree species belonging to 17 botanic families were identified. The most... |

Abstract: The objective of this work was to evaluate the effects of different arrangements of eucalyptus plants on the morphoanatomical characteristics of leaf blades of 'Marandu' grass [(Urochloa brizantha (Syn. Brachiaria brizantha)] plants cultivated in agrosilvopastoral systems. The experiment was set in field conditions in a randomized complete block design with four replicates, in which the plots were represented by planting spacings of eucalyptus (12x2 and 12x4 m), and the subplots, by the distance between 'Marandu' grass and eucalyptus rows (6, 4, and 2 m). A control was added, composed by 'Marandu' grass cultivated in full sun. Variables of the leaf anatomy of 'Marandu' grass were evaluated for shading interference by trees. The distance of... |

ABSTRACT In the Amazon region, agroforestry systems (AFSs) are recommended as a sustainable production alternative for local communities. A common component in Amazonian AFSs are tropical fruit trees, which can form the canopy or grow in the understory. In this study, we evaluated the effect of high radiation on photosynthesis, growth and seedling survival of four Amazonian fruit-tree species: Theobroma cacao, Eugenia stipitata, Inga edulis and Psidium guajava. Growth, chlorophyll fluorescence, gas exchange, and leaf pigments were measured in seedlings of each species grown for 12 months inside shade houses with low (8%), medium (30%) and high relative illumination (100%). Eugenia stipitata and T. cacao had the lowest acclimation capacity to high solar... |
