| ABSTRACT Tambaqui, Colossoma macropomum, is one of the most produced species in Brazilian fish farming, which has boosted the development of new technologies to increase its productivity. The aim of this study was to evaluate production performance in two second-generation tambaqui stocks selectively bred for weight gain in a semi-intensive rearing system and assess its influence on total production cost. We analyzed 300 fish (initial mean weight and standard length of 160 g and 17 cm, respectively) of two families (A and B, 150 fish each). The fish were individually marked with microchips and stocked in an 800-m2 excavated pond. For economic analysis, the obtained performance data were extrapolated for a fish farm with a 10-ha pond, adopting the Total... |

| The objective of this study was to evaluate the viability of pasture with high production capacity and the potential for production of silage using different sources and doses of nitrogen (N) by quantifying the productivity of dry matter (DM), some qualitative characteristics, the total cost of production (TC) and total operating cost (TOC) of silage production. The experimental design was randomized block in a factorial scheme with four replications including two sources of nitrogen (urea and ammonium nitrate) and five N doses (0, 50, 100, 150, and 200 kg ha-1 by cutting). The increase in N provided greater DM and crude protein content and reduced the fiber content in neutral detergent. The source of N did not affect the chemical composition, and... |

| O nitrogênio é o nutriente extraído em maior quantidade pelo milho, o de manejo mais complexo e o que mais onera o custo de produção da cultura. O objetivo deste trabalho foi avaliar a viabilidade econômica de diferentes doses e parcelamentos da adubação nitrogenada, na forma de uréia, na cultura do milho em LATOSSOLO VERMELHO Eutrófico. O estudo foi conduzido na Estação Experimental do Pólo Regional do Desenvolvimento dos Agronegócios do Noroeste Paulista (APTA), em Votuporanga, Estado de São Paulo. O delineamento experimental foi o de blocos casualizados com nove tratamentos e quatro repetições, constituído de cinco doses de N: 0, 55, 95, 135 e 175 kg ha-1, aplicando-se 15 kg ha-1 na semeadura e o restante em cobertura, combinadas a diferentes... |

| A área da região noroeste do Estado do Paraná, sobre o arenito Caiuá, carece de opções de exploração agrícola economicamente viáveis. Assim, o abacaxi apresenta-se como opção de cultivo, entretanto, necessitando de maiores estudos referentes à sua exploração nesta região. O presente trabalho teve por objetivo avaliar a viabilidade socioeconômica do cultivo desta frutífera na região de Umuarama, Estado do Paraná em relação às principais regiões fornecedoras de abacaxi para o Estado. Para tanto, visitaram-se três propriedades nos municípios de Umuarama, Cafezal do Sul e Cruzeiro do Oeste, objetivando levantar os coeficientes técnicos desta atividade e seus indicadores de lucratividade. A região analisada apresenta boa capacidade competitiva em relação às... |

| O objetivo foi avaliar a viabilidade financeira do fornecimento de cinco suplementos elaborados com diferentes fontes de óleo e proteína para abelhas africanizadas submetidas à produção de geleia real. Foi verificado se os investimentos com a suplementação das colônias proporcionam rentabilidade aos apicultores, a fim de proporcionar opções lucrativas para diversificação dos produtos apícolas. Para avaliar os cinco suplementos, realizaram-se dois ensaios experimentais. Em cada ensaio, 20 recrias foram divididas aleatoriamente em quatro tratamentos. Foram realizadas 15 observações por recria. No ensaio I, os tratamentos foram: óleo de linhaça mais óleo de palma, óleo de linhaça, óleo de palma e controle sem suplementação. No ensaio II, proteína isolada de... |

| This study aimed to analyze the economic feasibility of supplement probiotics Bacillus subtilis to “matrinxã” Brycon amazonicus, raised in cages. The experiment was conducted at the Polo Regional Vale do Ribeira, in Pariquera-açu municipality, São Paulo State, Brazil, from February to July 2009. A total of 960 juvenile matrinxã were stocked in twelve 2.7 m³-net cages (1.5 x 1.5 x 1.2 m), in ponds with a total area of 600 m2 and an average depth of 1.50 m. The tests were conducted with a control treatment (T1) and two probiotic doses (T2 = 5 g and T3 = 10 g kg-1 of diet) with four replicates. Results showed that T2 produced better economic performance for matrinxã at the juvenile stage in intensive rearing system. |

| The significance of a break-even point analysis is much important to the small- scale enterprises in determining profit or loss incurred. In this study, a case study approach was used to test this concept on iru production using structured oral interviews and visual observation of a production centre in Nigeria. Data analysis was achieved using production cost, the unit quantity and break-even point analysis. The results show that the monthly average cost of N 32,237.00, the monthly average variable cost of N71,334.00, Contribution Margin Ratio of 47.06 % and break-even sales of N 68,502.00 were obtained using a traditional method of iru production (TIPP). In a mechanized method (MIPP), monthly average fixed cost of N 85,887.00, the monthly average... |

| In this study, seven wine samples were prepared varying the amount of pulp of acerola fruits and the sugar content using the simulated annealing technique to obtain the optimal sensory qualities and cost for the wine produced. S. cerevisiae yeast was used in the fermentation process and the sensory attributes were evaluated using a hedonic scale. Acerola wines were classified as sweet, with 11°GL of alcohol concentration and with aroma, taste, and color characteristics of the acerola fruit. The simulated annealing experiments showed that the best conditions were found at mass ratio between 1/7.5-1/6 and total soluble solids between 28.6-29.0 °Brix, from which the sensory acceptance scores of 6.9, 6.8, and 8.8 were obtained for color, aroma, and flavor,... |

| ABSTRACT: The objective of this study was to evaluate the bioeconomic efficiency of beef cattle production systems in the south of Brazil. A survey was conducted with 33 beef cattle farmers operating with complete cycle production systems in areas larger or equal to 900 ha. Answers were classified in two drivers, technology (TEC) and management (MAN), which were separated into subfactors with their respective components. Multiple correspondence analysis, Tukey test, cluster analysis, and Pearson correlation were the statistics procedures. The TEC components were above normal for Brazilian farmers, but the gross margin is still lower than that needed to generate financial resources for a proper remuneration of cattle farmer. Farmers were classified into... |

| El estudio se realizo en el Ejido las Piedras, Municipio de Huimanguillo, Tabasco, México. Tuvo como objetivo estimar rendimiento y analizar costos de producción en el cultivo de Maíz sembrado en el ciclo primavera verano de 2008. Se realizaron muestreos de suelo para analizar la fertilidad antes y después de la cosecha, muestreos de lombriz de tierra para saber el número de individuos presentes en el suelo de las parcelas en estudio y la estimación de costos de producción se uso para saber cuánto gasto cada productor en el cultivo de Maíz (Zea Mays L.). Las parcelas en estudio fueron cuatro; La primera parcela fue sembrada en suelo acahualado dándole manejo químico, la segunda siembra fue realizada en terreno barbechado y se le dio manejo... |
