The aim of this study was to analyze technical and economic indicators of family milk production systems, with different technology levels, in the Caiuá sandstone area in Northwestern Paraná, Brazil. The analysis period covers the agricultural years 2002/2003 to 2013/2014. The categorization of the milk production systems was based on information from agricultural farms monitored by the Reference Network for Family Agriculture. The cost-benefit analysis method was used for the economic assessment of milk production. Based on the results, three family milk production systems were identified in the region, characterized by the use of low, medium and high intensification technologies for pasture management. The production costs per unit area were found to... |

El presente trabajo evaluó la factibilidad técnica y económica de la implementación del control biológico de ácaros plaga de papayo en la zona productora del Centro de Veracruz. Se colectó Tetranychus merganser Boudreaux en Manlio F. Altamirano, Ver. Se incrementó sobre frijol (Phaseolus vulgaris L.) en invernadero. Se estimaron los parámetros poblacionales a cohortes de T. merganser a 19, 23, 27, 31, 33 y 35 °C y del ácaro depredador Phytoseiulus persimilis Athias-Henriot (comercial: Koppert de México, S.A.) a 27 °C en todos los casos sobre hojas de papayo, a 60 (±2)% HR y 14:10 h luz: oscuridad. T. merganser presentó valores máximos de tasa neta reproductiva (R0 = 62.38) y de tasa intrínseca de crecimiento poblacional (rm = 0.21) a 23 y 27 °C, que... |

Lettuce and tomato are vegetables that can be grown in protected cultivation, under given conditions. Considering their expensive production systems, intercropping might be an excellent alternative to optimize costs. Four experiments were carried out at the São Paulo State University (UNESP), at Jaboticabal, Brazil, to study the economic viability of intercropping lettuce and tomato under protected cultivation. To set the intercropping, lettuce was transplanted 0, 10, 20, and 30 days after transplanting (DAT) tomato and vice-versa, in two seasons, namely April to September 2003 and January to June 2004, when monocultures of both vegetables were also carried out. At the first planting season, operational profits (OP) in intercropping (lettuce transplanted... |

Dado que o desenvolvimento de sistemas de produção orgânica, em relação aos convencionais, implica em mudanças importantes na estrutura e na tecnologia empregadas, buscou-se mensurar e analisar, em condições determinísticas e de riscos, os níveis de eficiência econômica e de viabilidade financeira da produção orgânica de 'Niágara Rosada', sem e com o uso de cobertura plástica, desenvolvida pela Embrapa Uva e Vinho. |

Previously published data and preliminary indications from research now in progress suggest the possible occurrence in offshore Nigeria of economically viable deposits of placer minerals (including heavy minerals), sand and gravel, phosphorite, glauconite, polymetalic manganese nodules etc. In addition, new stratigraphic evidence indicates the existence of potentially rich petroleum plays associated with a Tertiary canyon system in water depths beyond the limits of present exploitation. Based on the comparative geology of similar occurrences in better explored continental margins and ocean basins elsewhere, the possible origin, abundance and distribution of these resources are adduced. A brief assessment of the technology relevant to their discovery and... |

Abstract: The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C... |

The U. S. biodiesel industry is rapidly expanding due to energy production concerns, environmental concerns, and recent legislation. The most common type of biodiesel in the United States is derived from soybean oil. Soybeans are a major crop in North Dakota and could easily supply a 5 million gallon per year biodiesel facility. Potential market segments of a biodiesel facility in North Dakota include agriculture, construction, and state fleet sectors based on current diesel use. However, with existing technology and no subsidy, biodiesel operation and investment costs for a North Dakota facility are not competitive with petroleum diesel. Using soybean oil prices of 17 cents to 25 cents per pound, the per gallon cost of producing diesel in... |

In response to energy security concerns, alternative energy programs such as biomass energy systems are being developed to provide energy in the 21st century. For the biomass industry to expand, a variety of feedstocks will need to be utilized. Large scale production of bioenergy crops could have significant impacts on the United States agricultural sector in terms of quantities, prices and production location of traditional crops as well as farm income. Though a number of scenarios were examined to study the impact of bioenergy crop production on the agricultural sector, two cropland scenarios are presented in this report. Under the wildlife management scenario, the analysis indicates that, at $30/dry ton (dt) for switchgrass,... |

This current study aims to identify the most feasible type of packages for fresh oranges, produced and commercialized in the São Paulo state. In order to do so, three studies of specific cases were considered, under the context of multi cases. It was aimed to determine the cost of processing, packaging and transporting related to the orange commercialization aimed at customers such as wholesalers, supermarkets and Supplying Centers (CEASA’s), from a Packing-House. The results presented and analyzed in this study allowed to indicate that, in general terms, there is no package more feasible economically speaking, considering its use. What was really observed was that there is a package that is more feasible for each producer considering his specific... |

As water resources in arid regions decline, agricultural producers are encouraged to adopt water conserving strategies. The implementation of alternative low-water use crops is one option, but is it economically feasible? Data on current and alternative crops for this study include enterprise budgets, producer interviews, and field trials in Northwestern Nevada, USA. We use WinEPIC, a Windows-based version of the EPIC model, which synthesizes both agronomics and economics, to model yields and returns of alternative crop production under differing irrigation levels. Risk analysis or the distribution of net returns to alternative crop production is also examined. This study determined that there are alternative crops that could be feasibly substituted for... |

The feasibility of springbuck based meat production in the EC Karoo was analysed through a stochastic budgeting model, while overtly taking cost and price risk into consideration. Monte Carlo simulation of a springbuck based meat production enterprise was used to quantify the risks that would be faced by springbuck ranchers. Springbuck ranching has been proven a viable alternative in the production of highly nutritious and healthy meat (venison) that is on high demand in European markets and more recently with a promising and growing local demand as well. The results indicate that in the Eastern Cape Karoo, springbuck ranching for meat production is a viable business. As the call for more environmentally friendlier rangelands utilisation economic systems... |

The economic feasibility of alternative wetland restoration activities to store water and reduce flood damage was evaluated in the Maple River Watershed, North Dakota, a sub-watershed of the Red River of the North Watershed. The evaluation was based on recent hydrologic modeling and wetland restoration studies, the National Wetland Inventory, local land rental values, and site-specific historical flood damage. With benefit-cost ratios ranging from 0.08 to 0.13, neither simple wetland restoration based on plugging existing drains, nor restoration with outlet control devices, nor complete restoration intended to provide a full range of wetland-based environmental services were economically feasible over a 20-year future period. Peak flood stages and flood... |
