O experimento foi dividido em dois per?odos, que corresponderam a recria e o confinamento (termina??o), respectivamente. Foram utilizados 36 bovinos, n?o castrados, com m?dia de 270 ?50 dias de idade e peso m?dio inicial de 241,3 ?34 kg, sendo 12 Guzolando (? Guzer? x? Holand?s), 12 Guzonel (? Guzer? x ? Nelore) e 12 Tricross (? Simental x ? Guzonel). O delineamento estat?stico foi inteiramente casualizado (DIC), de forma que cada grupo foi considerado com um tratamento, e os animais, as repeti??es (3 x 12). Os animais permaneceram no mesmo lote, em pastejo rotacionado de Brachiaria brizantha cv. Marandu, com suplementa??o comercial; na termina??o, receberam dieta composta por silagem de sorgo e concentrado (50:50) durante 61 dias, ap?s adapta??o de 22 dias. Os ?ndices de desempenho foram ganho m?dio de peso di?rio (GMD), ganho m?dio de peso no per?odo (GMP), peso corporal final (PCF) nas duas fases al?m de ganho de peso de carca?a (GPC) na fase de termina??o. Os indicadores de desempenho econ?mico foram a receita total (RT), custo operacional total por arroba (COT/@), custo total por arroba (CT/@), margem l?quida e lucratividade. Os custos foram obtidos atrav?s da metodologia de custo operacional. O GMD, na recria, foi semelhante (P>0,05) aos grupamentos que apresentaram m?dia de 746 e 456 gramas, respectivamente, para os per?odos transi??o ?guas/secas. O COT/@ da recria do grupamento Tricross (R$ 69,44) foi superior aos dos grupamentos Guzonel (R$ 66,75) e Guzolando (R$ 64,86). No per?odo de termina??o, o GMD do grupamento Guzolando (1,65 kg/dia) foi superior estatisticamente (P<0,05) ao do Guzonel (1,39 kg/dia), por?m sem diferen?a estat?stica (P>0,05) ao do Tricross (1,26 kg/dia). O GPC foi maior (P<0,05) para o grupamento Tricross (79,79 kg), por?m n?o diferiu estatisticamente (P>0,05) entre os grupamentos Guzonel (62,62 kg) e Guzolando (59,41 kg). O COT/@ da termina??o em confinamento foram R$ 91,48, R$114,15 e R$122,78, respectivamente, para os grupamentos Tricross, Guzonel e Guzolando. Considerando-se a an?lise do sistema de ciclo curto com a inclus?o dos dois per?odos experimentais, obteve-se um COT/@ menor para o grupamento Tricross (R$77,92) seguido pelo grupamento Guzonel (R$ 74,89) e Guzolando (R$ 78,43). Esses resultados propiciaram maior lucratividade para os cruzamentos Tricross (21,99%) comparados aos demais cruzamentos (18,92% e 18,31%, respectivamente, para Guzonel e Guzolando), o que indica a op??o deste tipo de cruzamento na regi?o estudada. / Disserta??o (Mestrado) ?

The experiment was divided into two periods, corresponding to recreate and confinement (termination), respectively. We used 36 cattle bulls, averaging 270 days of age (? 30) and average weight of 241.3 kg (? 34), divided into three groups: Guzolando (X ? ? Guzer? Dutch), Guzonel (? Guzer? X Nelore) and Tricross (X ? Simmental ? Guzonel). The experimental design was completely randomized (CRD) and each group was considered a treatment and animals repetitions (3 x 12). These remained in the same batch, in rotational grazing Brachiaria brizantha. Palisade, supplementation with commercial and termination received diet containing sorghum silage and concentrate (50:50) for 61 days, after 22 days of adaptation. The performance indices were average daily weight gain (ADG), average daily gain during the period (GMP), final body weight (PCF) in the two phases as well as gain carcass weight (GPC) in the finishing phase. The economic performance indicators were total revenue (TR), total operating expenses per bushel (COT / @), total cost per bushel (CT / @), net margin and profitability. Costs were obtained through the methodology of operational cost. The ADG during the growing phase was similar (P> 0.05) between the groups with a mean of 746 and 456 grams, respectively, for the period?s transitional waters / dry. The COT / @ recreates the grouping of Tricross (R$ 69.44) was higher than that of groups Guzonel (R$ 66.75) and Guzolando (R$ 64.86). In the finishing period, ADG of grouping Guzolando (1.65 kg / day) was statistically higher (P <0.05) to the Guzonel (1.39 kg / day), but no statistical difference (P> 0.05) of the Tricross (1, 26 kg / day). The GPC was higher (P <0.05) to the grouping Tricross (79.79 kg), though not significantly different (P> 0.05) between the groups Guzonel (62.62 kg) and Guzolando (59.41 kg.) The COT / @ the feedlot finishing were R $ 91.48, R $ 114.15 and R $ 122.78 respectively for the groups Tricross, and Guzonel Guzolando. Considering the analysis of the short-cycle system with the inclusion of the two experimental periods, we obtained a COT / @ lowest for grouping Tricross (R$ 77.92) followed by grouping Guzonel (R$ 74.89) and Guzolando (R$ 78, 43). These results provided higher profitability for the crosses Tricross (21.99%) compared to other intersections (18.92% and 18.31% respectively, and for Guzonel Guzolando) which indicates the choice of this type of intersection in the study area.

Ruhl (p?- de-ouro) are everlasting flowers more commercially exploited in the region of Diamantina. The extractive such an important source of income for many families do Vale do Jequitinhonha. The areas of occurrence of these species are decreasing drastically due to excessive pressure of collection and management with fire, which is placed after the first rains (sept. / oct.) And is used frequently aimed at increasing the production of flowers. According to collectors in the year when the fire does not arise, the production of subsequent chapters in the harvest is reduced. The interference of vegetation cover in the penetration of light is an important aspect in the management of the species. In handling the ever-living, the fire can act eliminating the shading caused by other species that occur associated with them and thus change the penetration of light, interfering with the germination, vegetative growth and production of flowers. Information on the responses plant in different conditions of light is of great importance to determine their potential for production and understand its competitive capacity under different conditions of management. The objective was to study the behavior of physiological and anatomical S. elegans and S. elegantulus grown in pots, under two levels of radiation (full sun and sombrite 50%).

Diamantina, in the Alto Vale do Jequitinhonha, due to its altitude, shows the occurrence of low temperatures during winter, which may enable the cultivation of the blackberry with good economic expectations. However, the phenological study is essential for the identification of cultivars adapted to new growing regions. Therefore, the research was carried out to evaluate the phenological and productive behavior of blackberry cultivars in Diamantina, Minas Gerais. The nursery blackberry were planted in the Fruitculture Sector of Campus Juscelino Kubitschek, UFVJM, located at 1,384 m altitude. The climate is the type Cwb, temperate humid with dry winter and rainy season from October to March, with annual precipitation of 1,404 mm and mean temperature of warmest month lower to 20,1?C. The soil type of the crop area is Quartzarenic Neosol. The study was conducted in a randomized block design with four blackberry cultivars Brazos, Guarani, Tupy and Xavante, with five blocks and five plants per experimental unit. The phenological characterization was carried in blackberry cultivars through visual observations to determine the beginning of flowering, formation and ripening fruits, length of the period flowering and harvest. To characterize the thermal demand was calculated the number of chilling hours accumulated less than 13 ?C, 10 ?C and 7,2 ?C before the stage of issuance of gems and during each stage from hours temperature data collected by automatic station installed in Campus Juscelino Kubitschek, Diamantina, MG. The degree-days in the different phenological phases were determined from the difference between the daily average temperature and lower basal temperature, which was taken as 10 ?C. The quality and production of blackberries were evaluated from the physico-chemical characteristics, centesimal composition, antioxidant activity, the fruit mass harvested per plant and the productivity per hectare. The cultivars of blackberry showed good adaptation to climatic conditions Diamantina, MG. The cold occurrence with temperatures above 7.2 ?C was enough to production of blackberry cultivars Brazos, Guarani, Tupy e Xavante in Alto Vale do Jequitinhonha. The cultivar Brazos showed precocious behavior, with the anticipation of the production phase. The productive cycle of blackberry cultivars in the conditions of climate Diamantina was prolonged. These climatic conditions provided satisfactory production to cultivate Brazos in its second productive cycle. The blackberry quality produced in Diamantina were maintained, with variations consistent to climate change in the region. The blackberry quality is best when harvested in the dry season with low rainfall and high solar radiation.

This research aimed to describe the production system and food marketing in the street market at Couto de Magalh?es de Minas, Minas Gerais. Based on informations of the Secretaria Municipal de Agricultura, Pecu?ria e Meio Ambiente and the regional office of Empresa de Assist?ncia T?cnica e Extens?o Rural, some rural communities were visited to identify properties with some food production. In the production areas selected, it was evaluated the installations domiciliary, the food production systems and was identified which types of foods produced. During 27 weeks, visits were made to the fair to identify and characterize the products sold by the stallholders. A questionnaire was applied to 25 consumers, in order to obtain information about their reasons for attending the fair. In the rural area, 61 farmers (mean age of 54.46 years) were interviewed and 44.26% reported that ever lived in the same properties. With respect to the food production, 44.26% responded that it is for their own consumption, while 19.67% sell their products directly at the municipal street markets. Fruit trees were identified in 86.89% of peridomestic areas, while garden is present in 75.41%, being that the lettuce and cabbage configured as the more commons vegetables. The use of fertilizers has been reported by 19.68% of producers interviewed and the 80.32% use only organic fertilizer. In the street market, 23 stallholders were assiduous, with an average age of 52 years and and the majority (69.56%) were female. The merchants usually sold territorially-based foodstuffs and it was observed that some of them were taken to the fair in all weeks of the study, such as lettuce, onions, meats and bakery products. Some kind of products were marketed by various stallholders, like orange and cabbage, however meat products and processed food were sold by specific marketers. Sanitary-hygienic aspects of stallholders were also evaluated and showed non-conformities, such as those related to hand hygiene. Regarding consumers, 56.00% visit the fair with the intention of shopping and 44.00% to stroll and meet friends. We conclude that the family farmers follow a traditional production system, guided by local resources environment-related. Furthermore, the street market is an important way of marketing of local products, besides it is a recreation area, that contributes to the socialization of Couto de Magalh?es de Minas residents.

Foram utilizadas oito vacas F1 (Holand?s x Zebu) no ter?o inicial de lacta??o, com produ??o m?dia de 12,7 kg (? 3,1 kg) de leite/dia e 552 kg (? 30 kg) de peso vivo. O delineamento experimental foi composto de dois quadrados latinos simult?neos 4x4, de acordo com os seguintes tratamentos: Controle (100% de farelo de soja e 0% de ULL), 34ULL (66% de farelo de soja e 34% de ULL), 66ULL (34% de farelo de soja e 66% de ULL) e 100ULL (0% de farelo de soja e 100% de ULL). O volumoso fornecido, juntamente ao concentrado, foi silagem de sorgo. Amostras das dietas e das sobras foram coletadas para an?lises bromatol?gicas. Foram mensurados os consumos de mat?ria seca (CMS), de prote?na bruta (CPB) e de fibra em detergente neutro (CFDN). Os consumos tamb?m foram expressos em fun??o do peso corporal (CMSPC, CPBPC e CFDNPC) e do peso metab?lico (CMSPM, CPBPM e CFDNPM). A efici?ncia alimentar (EA) e a convers?o alimentar (CA) tamb?m foram calculadas. As digestibilidades aparentes da mat?ria seca (DAMS), da prote?na bruta (DAPB) e da fibra em detergente neutro (DAFDN) foram avaliadas utilizando o ?xido cr?mico como marcador externo. A produ??o de leite foi mensurada e sua composi??o analisada. Os dados obtidos foram submetidos ? an?lise de vari?ncia, atrav?s do programa estat?stico SAEG, adotando-se o n?vel de 5% de probabilidade. Nenhuma vari?vel de consumo apresentou diferen?a significativa (P>0,05) entre tratamentos, sendo que as m?dias de CMS, CPB e CFDN foram 18,35 kg/dia, 2,62 kg/dia e 5,85 kg/dia, respectivamente. J? as m?dias de CMSPC, CMSPM, CPBPC, CPBPM, CFDNPC e CFDNPM foram 3,39 %, 163,61 g/kg de PC0,75, 0,48 %, 23,35 g/kg de PC0,75, 1,08 % e 52,19 g/kg de PC0,75, respectivamente. A efici?ncia alimentar apresentou m?dia de 0,72 kg leite/kg CMS e a convers?o alimentar m?dia foi 1,44 kg CMS/kg leite e n?o foram observadas diferen?as significativas (P>0,05) entre tratamentos para ambas vari?veis. Os resultados de digestibilidade aparente tamb?m n?o apresentaram diferen?as (P>0,05) entre tratamentos, sendo que as m?dias observadas para a DAMS, DAPB e DAFDN foram 58,16 %, 58,64 % e 36,21 %, respectivamente. A produ??o e composi??o do leite foram semelhantes (P>0,05) entre tratamentos. A m?dia de produ??o de leite corrigida para 4% de gordura foi 13,39 kg/animal/dia e as m?dias dos teores de gordura, prote?na, extrato seco total e extrato seco desengordurado foram 3,78 %, 3,23 %, 12,79 % e 9,00 %, respectivamente. As vari?veis de consumo, de digestibilidade, de produ??o e de composi??o do leite n?o s?o alteradas em fun??o da substitui??o da prote?na da soja pela ureia de libera??o lenta.

Eight cows F1 (Holstein x Zebu) in the first third of lactation, with an average production of 12.7 kg (? 3.1 kg) of milk / day and 552 kg (? 30 kg) of body weight. The experimental design was composed of two 4x4 Latin square, according to the following treatments: control (100% soybean meal and 0% SRU), 34SRU (66% soybean meal and 34% SRU), 66SRU (34% soybean meal and 66% SRU) and 100SRU (0% soybean meal and 100% SRU). The forage supplied along to concentrate was sorghum silage. Samples of diets and remains were collected for chemical analysis. We measured dry matter intake (DMI), crude protein intake (CPI), neutral detergent fiber intake (NDFI). The intakes were also expressed according to the body weight (DMIBW, CPIBW and NDFIBW) and metabolic weight (DMIMW, CPIMW and NDFIMW). Feed efficiency (FE) and feed conversion (FC) were also calculated. The apparent digestibility of dry matter (ADMD), crude protein (ADCP) and neutral detergent fiber (ADNDF) were evaluated using chromic oxide as an external marker. Milk production was measured and its composition analyzed. Data were subjected to analysis of variance using the statistical program SAEG, adopting the 5% level of probability. No variable intake showed a significant difference (P>0.05) between treatments, and the averages of DMI, CPI and NDFI were 18.35 kg/day, 2.62 kg/day and 5.85 kg/day, respectively. The averages of DMIBW, DMIMW, CPIBW, CPIMW, NDFIBW and NDFIMW were 3.39 %, 163.61 g/kg BW0,75, 0.48 %; 23.35 g/kg BW0,75, 1.08 % and 52.19 g/kg BW0,75, respectively. Feed efficiency presented mean of 0.72 kg milk/kg DMI and average feed conversion was 1.44 kg DMI/kg milk and no significant differences were observed (P>0.05) between treatments for both variables. The results of apparent digestibility also do not present differences (P>0.05) between treatments, and the averages observed for ADMD, ADCP and ADNDF were 58.16 % 58.64 % and 36.21 %, respectively. The production and milk composition were similar (P>0.05) between treatments. The average milk yield corrected to 4% fat was 13.39 kg/animal/day and the average of the levels of fat, protein, total dry extract and nonfat dry extract were 3.78 % 3.23 %, 12.79 %, and 9.00 %, respectively. The variables of intake, digestibility, production and milk composition do not change due to the substitution of soy protein for slow release urea. Thus for crossbred animals average milk production, this substitution depends only on economic variables.

Por?m, muitos s?o os estudos que devem ser realizados, antes que se inicie o plantio comercial em larga escala. O manejo correto da aduba??o eleva o lucro do produtor de duas formas. Primeiro, evita o gasto de fertilizantes em quantidades erradas e, depois, favorece o melhor desempenho da planta, proporcionando maior produtividade. Este trabalho objetivou avaliar a resposta do pinh?o manso (Jatropha curcas L.) a doses de NPK no crescimento de plantas e, no crescimento de plantas, produ??o de sementes e de ?leo em duas condi??es edafoclim?ticas. Para tanto, foram montados dois experimentos: o primeiro, em condi??es de casa de vegeta??o, teve os tratamentos dispostos em delineamento inteiramente casualizado, no esquema de fatorial fracionado (4x4x4)1/2, perfazendo 32 tratamentos com tr?s repeti??es, totalizando 96 parcelas experimentais, sendo as doses de N: 0, 75, 150 e 300 mg dm-3, na forma de ur?ia; doses de P: 0, 45, 90 e 180 mg dm-3, na forma de superfosfato triplo e doses de K: 0, 50, 100 e 200 mg dm-3, na forma de cloreto de pot?ssio. Ap?s 120 dias, foram avaliadas as seguintes vari?veis: altura das plantas, di?metro do caule, massa seca da parte a?rea e de ra?zes; an?lise qu?mica do solo ap?s a colheita das plantas e teor de macro e micronutrientes na parte a?rea das plantas. O segundo foi conduzido em campo, em duas condi??es edafoclim?ticas, em Diamantina e Governador Valadares, Minas Gerais. Ambos foram conduzidos da mesma forma: o delineamento utilizado foi o delineamento em blocos casualizados no esquema de fatorial fracionado (4x4x4)1/2, perfazendo 32 tratamentos. Foram aplicadas doses de N: 0, 25, 50 e 100 kg ha-1, na forma de ur?ia; doses de P2O5: 0, 75, 150 e 300 kg ha-1, na forma de superfosfato triplo e as doses de K: 0, 50, 100 e 200 kg ha-1, na forma de cloreto de pot?ssio. Foram avaliados o crescimento das plantas pela medi??o da altura de plantas e di?metro na altura do colo do caule a cada 30 dias; produ??o de sementes e de ?leo com uma colheita em Diamantina, em 2009, e duas colheitas em Governador Valadares, em 2008 e 2009. As plantas responderam negativamente ? adi??o de N e positivamente ao P e K , mostrando que o pinh?o manso ? eficiente na absor??o de N, que foi suprido pela mat?ria org?nica do solo. J? em campo, o pinh?o manso apresentou comportamentos distintos nas duas condi??es edafoclim?ticas. Em Governador Valadares, houve resposta positiva ? aplica??o de N e, em Diamantina, resposta negativa a N e positiva a P. N?o houve resposta a K em campo, indicando que o teor do solo foi suficiente para suprir a planta em todas as fases. No experimento de vaso, as doses de P e K recomendadas foram 25 e 67 mg dm-3, respectivamente.

However, many studies must be carried out before beginning the large-scale commercial growing. The accurate fertilization increases the producer's profit in two ways, first avoids the fertilizers expense in the wrong quantities and then promotes better plant performance for higher productivity. This study evaluated the physic nut (Jatropha curcas L.) response to NPK doses on seedlings growth and plant growing, seed and oil production in two edaphic and climate conditions. Therefore, there were arranged two experiments: the first, in controlled conditions, was arranged in a completely randomized design, in the fragmented factorial scheme (4x4x4)1/2 comprising 32 treatments with three replicates totaling 96 plots and the N doses: 0, 75, 150 e 300 mg dm-3, in the urea form; P doses: 0, 45, 90 and 180 mg dm-3, in the triple superphosphate form and K doses K: 0, 50, 100 and 200 mg dm-3, in the potassium chloride form. After 120 days, there were evaluated the following variables: seedlings height, stem diameter, the shoot and roots dry mass and nutrients content in the soil and in the seedling shoot macronutrients and micronutrients. The second was conducted in field conditions on two places with distinct edaphic and climate conditions, Diamantina, MG and Governador Valadares, MG. Both were conducted in the same way, the design was in randomized blocks, in the fractional factorial scheme (4x4x4) 1 / 2. The N doses were applied: 0, 75, 150 and 300 mg dm-3, in urea form; P doses: 0, 45, 90 and 180 mg dm-3, in the form of triple superphosphate and K doses: 0, 50, 100 and 200 mg dm-3, in the potassium chloride form. There were evaluated the plants growth by the measure of plants height, stem diameter every 30 days, seeds and oil production with one harvest in Diamantina in 2009 and two harvests in Governador Valadares in 2008 and 2009. Seedlings responded negatively to N addition and positively to P, showing that physic nut is efficient in N uptake that was supplied by soil organic matter. Therefore, in the field physic nut showed different behavior in both edaphic and climate conditions. In Governador Valadares there was positive response to N application and in Diamantina there was negative response to N and positive for P. There was no response to K in either experiment, indicating that the content of the soil was sufficient to supply the plant at all stages. Seedlings responded negatively to N addition and positively to P. There was no response to K field, indicating that the content of the soil was sufficient to overcome the plant at all stages. In pot experiment the recommended doses of P and K were 25 and 67 mg dm-3, respectively. The critical level corresponding to the recommended dose, were 10.6 for P and 74.0 mg dm-3 for K in soil (Mehlich-1). For contents in shoot dry mass of physic nut seeds were 3.74, 0.18 and 3.57 dag kg-1 for N, P and K, respectively. The P recommended doses for growth, seeds and oil of physic nut in Diamantina was 87, 72 and 72 kg P2O5 per ha, respectively. In Governador Valadares, there was no nitrogen indication for the plants growth phase, for oil and seeds production and the recommended dose was 36 and 31 kg ha-1 N, respectively.

Due to the increase in computational resources, the production of this type of educational material grew and began to incorporate practices of software production in general, highlighting some peculiarities due to the educational objectives proposed in the objects. Thereat, the introduction of Software Engineering practices is increasingly present in the production of learning objects, and, as in software production, the qualification of this production process has become a necessity. In software production, a consolidated solution for production qualification is in the evaluation frameworks, such as CMMI and MPS.BR. In order to think this type of solution for the production of learning objects, this research presents a framework to support the reflection on the practices performed by the centers of production of learning objects. This framework is a result of the triangulation of pertinent practices related to the theme obtained from a literature review (including a systematic review and systematic mapping) and from interviews with members of nine Brazilian learning object centers. As a result obtained after the analysis of adherence of the practices by the centers, stands out its capacity to promote the reflection of the production process, as well as well as to encourage them to carry out new practices. / A produ??o de objetos de aprendizagem aliou as ?reas da tecnologia e da educa??o, sendo um fator chave para trazer novas possibilidades de aprendizagem.

It has been analyzed a database related to milk producers who are providers to a national dairy processing industry, composed of information related to fixed capital of the property, to milk production, total costs and the income of properties located in the Northeast, South and Southeast regions of Brazil. The information from the database covered a period of 48 months (July 2010 to June 2014). Seeking to diagnose the socio-cultural profile of human resources, closed-ended questionnaires were applied to rural producers with the collaboration of technicians who watched and collected data from the properties in each individual industrial plant of the company. Each technician or producer, between July 2015 and September 2015, filled a questionnaire, completing a total of 85 samples of milk producers from different regions of the national territory that, after eliminating inconsistencies and discrepancies, allowed to a consistent sample of 33 producers. It has been extracted from the database information regarding relative and absolute composition of elements that form the total cost of production, as well as some indicators of economic efficiency. The expense items were allocated in fixed costs, variables and expenses, and later analyzed in the Safari computer program - version 1?2012. It has also been collected investment data and property income. Economic performance analysis and zootechny performance had also been made, using the procedure ANOVAG from SAEG program, version 9.1 (SAEG, 2007), comparing the averages by Tukey test to the maximum level of 5% of error. It has been observed differences in the social profile of producers and employees, as well as the production and economic performance of the properties in Brazil due to the dairy region. Producers from the Northeast had higher levels of education, and the majority of these ones, were living in the dairy property, as well as the milk producers from the Southeast and South of Brazil. The total number of employees in the properties of milk producers from Northeast is higher than in the other regions. Most of the employees of the analyzed properties had lower level of education they were living in the properties where they worked and they are male. In relation to the total cost of production, it had been observed higher results in the properties from the Northeast. Concentrated feeding, labor and depreciation were, respectively in descending order, the items with greater representation in the total costs. Among the economic performance indicators, the monthly value earned with the sale of milk was larger in the dairy producers from Northeast. The values of Gross Margin and Net Margin were positive, indicating that the properties are being paid in the short term. The Total Revenue is greater than the Average Costs thus dairy farming is economically viable. The results were positive ROIC in the properties of basins Southeast and South, the activity is remunerating capital assets, and the producer can continue in business. Within zootechny performance indicators, the productivity by area and by employee, the daily milk production by cow and by lactation were superior to the South milk producers. / Este trabalho objetivou analisar o perfil das propriedades rurais em diferentes bacias leiteiras e sua influ?ncia nos desempenhos zoot?cnico e econ?mico da atividade. Foi analisado um banco de dados relativos a produtores de leite fornecedores de uma ind?stria de transforma??o de leite e produ??o de l?cteos de ?mbito nacional, composto por informa??es referentes ao capital imobilizado da propriedade, ? produ??o de leite, aos custos totais e a renda de propriedades localizadas nas regi?es Nordeste, Sul e Sudeste do Brasil. As informa??es do banco de dados compreenderam um per?odo de 48 meses (julho/2010 a junho/2014). Para diagnosticar o perfil sociocultural dos recursos humanos, aplicou-se question?rios fechados aos produtores rurais, com colabora??o dos t?cnicos que assistiam e coletavam dados das propriedades em cada planta industrial da empresa. Cada t?cnico ou produtor, entre julho/2015 e setembro/2015, preencheu um question?rio, perfazendo um total de 85 amostras de produtores de leite de diferentes regi?es do territ?rio nacional que, ap?s elimina??o de inconsist?ncias e incongru?ncias, permitiu a uma amostra consistente de 33 produtores. Foram extra?dos do banco de dados informa??es concernentes ? composi??o relativa e absoluta dos elementos que compunham o custo total de produ??o, bem como alguns indicadores de efici?ncia econ?mica. Os itens de disp?ndios foram alocados em custos fixos, vari?veis e despesas e posteriormente analisados no programa computacional Safari ? vers?o 1/2012. Tamb?m foram coletados os dados de investimentos e de renda da propriedade. Foram feitas an?lise de desempenho econ?mico e zoot?cnico, utilizando-se o procedimento ANOVAG do programa SAEG, vers?o 9.1 (UFV, 2007), sendo as m?dias comparadas por teste Tukey ao n?vel m?ximo de 5% de erro. Foi observado diferen?as no perfil social dos produtores e dos funcion?rios, assim como nos desempenhos produtivo e econ?mico das propriedades no Brasil em fun??o da bacia leiteira. No Nordeste os produtores possu?am maiores n?veis de escolaridade, e estes, em sua maioria, residem na propriedade leiteira, assim como os produtores das bacias Sudeste e Sul. Na bacia nordestina n?mero total de funcion?rios das propriedades ? superior ao das demais regi?es. A maioria dos funcion?rios das propriedades estudadas possui baixo n?vel de escolaridade, residem na propriedade e s?o do g?nero masculino. Foi observado resultados mais elevados de custo total de produ??o nas propriedades nordestinas. A alimenta??o concentrada, a m?o de obra e a deprecia??o foram, em ordem decrescente respectivamente, os itens com maior representa??o nos custos totais. Dentre os indicadores de desempenho econ?mico, o valor mensal da venda do leite foi maior na bacia Nordeste. Os valores de Margem Bruta e Margem L?quida foram positivos, indicando que as propriedades est?o sendo remuneradas no curto prazo. A Receita Total ? maior que os Custos M?dios, assim, a atividade leiteira ? vi?vel economicamente. Os resultados do ROIC foram positivos nas propriedades das bacias Sudeste e Sul, a atividade est? remunerando o capital imobilizado, e o produtor pode continuar no neg?cio. Dentro dos indicadores de desempenho zoot?cnico, a produtividade por ?rea e por funcion?rio, a produ??o de leite por vaca por dia e por lacta??o foram superiores na bacia Sul.

A cidade de Dimantina-MG ? considerada o maior polo de extra??o e comercializa??o de sempre-vivas no pa?s. Para muitas fam?lias, a extra??o de sempre-vivas constitui a principal fonte de renda, o que gerou a coleta predat?ria de muitas esp?cies que atualmente fazem parte da lista vermelha de esp?cies amea?adas de extin??o, acarretando a proibi??o da exporta??o dessas esp?cies. A presente pesquisa avaliou a fenologia de tr?s esp?cies de sempre-vivas: S. elegans, S. venustus e S. bisulcatus, em uma ?rea experimental de cultivo. As esp?cies apresentam comportamento fenol?gico semelhante quanto ?s ?pocas e dura??o das fenofases. Apresentaram grande crescimento vegetativo at? dezembro, m?s no qual se inicia a produ??o de escapos. A presen?a de cap?tulos em antese ocorreu na segunda quinzena de janeiro em S. bisulcatus, e em mar?o nas outras esp?cies. Entre os meses de abril e maio, teve in?cio a frutifica??o para as tr?s esp?cies, sendo observada em maio a presen?a de sementes imaturas, per?odo em que acontece a coleta para comercializa??o, prejudicando o recrutamento de novos indiv?duos. A pesquisa tamb?m objetivou o desenvolvimento de metodologias para compara??o e defini??o de m?todos de amostragem que possibilitam a avalia??o da produ??o em ?reas de ocorr?ncia de sempre-vivas. Os resultados obtidos se mostram preliminares, por?m, o uso de parcelas de 60 ou 100m2 e a p?s-estratifica??o se mostraram eficientes na amostragem de campos de ocorr?ncia de S. elegans. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT ?Campos Rupestres? are the Centre of genetic diversity of Eriocaulaceae. Diamantina ? MG is considered the highest polo of extraction and commercialization of everlasting flowers, being it the more important source of income for many families. This situation generated predatory collection of species that are nowadays threatened of extinction, causing the prohibition of exporting. This study used an experimental area in order to evaluate three everlasting species: S. elegans, S. venustus and S. bisulcatus. Species showed similar phenological behaviour relating to times and stages. Up to December they showed high vegetative growth, the month when scapes production is initiated. Capitula under anthesis occurred at the second fifteen days to S. bisulcatus, and in March to the other species. Between April and May fructification started to three species, being noticed the presence of immature seeds in May. At this time, collection happens in order to commercialize, having a negative impact on new individual recruitment. This study aimed also to develop methodologies to compare and define sampling methods to provide production evaluation in areas of everlasting flowers. Results seem preliminar, however, using parcels of 60 or 100m2 and post-stratification are efficient on sampling at S. elegans fields.
