Caracterização da produção e qualidade físico-química de méis produzidos no Estado de Pernambuco

The present study had as objective contribute to the characterization of beekeeping in the Pernambuco State and evaluate the physical-chemical quality of the honeys produced in the region. For this, was applied a directed formulary to the representative organ of beekeeping class aboutthe productives and technicals aspects of beekeepers. Was obtained 14 samples of honey by Apis mellifera africanized, stored in sterile plastic vessels was sent to the Beekeeping Products Quality Control Laboratory (CEA-UNITAU). Was observed that the most of beekeepers have of 50 to 100 hives (57,14%), 28,57% of 100 to 200 hives and 14,28% more than 500 hives, being that 85,71% produce 30 to 50 kg honey/hives/flowering. All use the standard hive Langstroth and 85,71% obtain their swarm by capture. About the physical-chemical quality of the honey, was observed that moisture content varied from 18,2% to 22,0%, with mean value of 19,80±1,11; the water activity varied from 0,70 to 0,84 aw, with mean value of 0,79±0,05 aw; the total acidity was 24,91±8,99 meq/kg and the average index of hydroxymethylfurfural was 16,32±17,88 meq/kg. The results obtained are according to the quality limits established by the brazilian legislation, excepted the water activity that exceeded the maximum limit of 0,65 aw. The datasobtained in this paper shows the development of beekeeping in Pernambuco State and the honey presents nice quality.

Análise das eficiências energética e econômica de dois diferentes sistemas de produção de leite bovino em explorações familiares

This study aimed to analyze the energy efficiency ratings and cost of farming families producing milk in the city of Pardinho (SP). The hypothesis that guides the study is that energy expenditure may be coincident with the economic expenditure showing that there is a relationship between these flows, which can be sustainable or not. To better define the producers studied criteria were used in the official system of rural credit FEAP. Through primary data obtained by the speeches, the itineraries were reconstituted technical detailing the operations employed. Thus, we found two producers with different technical routes. The producer was the one who got one of the highest efficiencies 8.66 and 1.48 respectively. Related to the efficiency, we can see that are close related and when there is a broader idea of the allocation of energy resources and, thus, a better view of the sustainability of the agro ecosystem.

Eficiência energética e econômica da produção de leite bovino em explorações familiares no município de Pardinho, região de Botucatu- SP

The study aimed to analyze the energy and economic efficiency rate family farms producing milk in the county of Pardinho, Sao Paulo State. The criteria used to define producers in this study is that outlined by the Brazilian agricultural credit system FEAP (Fund Expansion of Agribusiness Paulista). Through primary data, obtained by verbal reports, the agroecosystem technical itineraries were re-established, detailing the process applied, machinery, implements, equipment, supplies and manual work. These were transformed into energy and economic units, which allowed determining the established connection between energy economics outputs and inputs. The hypothesis of this study is that the energetic expenditure may be coincidental with economic expenditures. The energetic and economic flows were analyzed, using a structure of expenditures, by type, source and form of gross energy, as well as the energetic point of view. Four producers were found to have different technical itineraries. Producers 1 and 2 achieved the highest energy and economic efficiency rates. The producer with the lowest efficiency rates was producer 4. The energy sources not renewable like chemical fertilizers were the most used reaching an average of 82.9% for the energy and 52.86% for the economic expenditures. When comparing energy and economic efficiency it is possible to verify that both forms of analysis are close, obtaining a broader idea about energy resources allocation.

Eficiência energética de sistemas de produção de mamona no Estado de Minas Gerais

The objective of this study is to determine the economical and energetic efficiency of the castor bean culture in "Zona da Mata" and South of Minas Gerais. Through the method of simulation "Monte Carlo", we verified the probabilities of occurrence of the economical, cultural and energetic efficiency indexes. In relation to the production systems of castor bean in Minas Gerais in the season 2005/2006, we established that the variables price and productivity were the most noticeable for the producers from "Zona da Mata", while in the South of Minas it was productivity. We verified that the probability of the economical efficiency index to be lower than one was 43,26% for the producers from "Zona da Mata" and 39,57% for the ones from the South of Minas. The medium price received covered the medium costs of production. However, we observed that the medium costs in these regions of Minas Gerais, were over the minimum price. Regarding the energetic analysis, the results showed that the systems in the regions studied in Minas Gerasi, presented average of cultural efficiency indexes of 8,26 and 18,89. We concluded that despite the result being favorable from the energetic point of view, from the economical sustainability point of view there is the need of a more effective support policy for the castor bean, taking into consideration that the expectations of the producers with PNPB were not confirmed.

Avaliação energética econômica do agroecossistema algodão: uma abordagem entre sistemas familiares de produção do Paraguai e do Brasil

The objective of this work was to evaluate the energy and economic efficiency indexes per unit of cotton agro-ecosystem area in family production systems of Paraguay and Brazil; and, to establish a relationship between the energy and economic. Typologies presented by the Program to Support Small Cotton Holdings (Paraguay), and by the National Program for Strengthening Family Agriculture (Brazil). Family systems of the two countries were identified; these are located from Paraguay (San Juan–CA) and from Brazil (Leme–SP). To construct the energy expenditure structure of the cotton agro-ecosystem, as well as to assess the economic efficiency, the mean values obtained were considered, when they presented similarities in production systems and they were within the typology proposed in this study. From the technical itinerary observed the Paraguayan agro-ecosystem depended (fossil fuel 56.76%) and industrial source (35.99%). Thus, the energy balance of the agricultural stage was established, which attained a value of 17,740.69 MJ ha-1; an energy efficiency of 5.28, and a cultural efficiency of 3.04. The Brazilian agro-ecosystem depended on energy from industrial source (insecticides 39.82%) and from fossil fuel (33.59%); it reached an energy balance of 19,547.88 MJ ha-1; an energy efficiency of 2.12, and a cultural efficiency index of 0.71. In the economic and energy indicator ratio, with regard to the months referring to the harvest time, that is to say, March, April, and May, the maximum economic efficiency indicator of paraguay was attained in the month of May (1,00), and from Brazil in the month of May (1,71). Both production systems analyzed were presented efficient, however, dependent of external circumstances and non-renewable energy sources.
