A pesquisa foi conduzida objetivando avaliar o rendimento, a composição químico-bromatológica e as perdas de fenos triturados de milheto, sorgo sudanense, capim-elefante e sorgos forrageiros (SF-25 e IPA-467-4-2). Os materiais foram colhidos quando atingiram 30% de inflorescências, com exceção do capim-elefante, colhido aos 60 dias. Utilizou-se delineamento de blocos completos casualizados, com cinco tratamentos e quatro repetições. Houve diferenças significativas, com maiores produções de feno para os sorgos IPA-467-4-2 (10,85 t/ha/corte) e SF-25 (10,65 t/ha/corte), que foram superiores ao capim-elefante, sorgo sudanense e milheto, com, respectivamente, 6,94; 6,69 e 4,93 t/ha/corte. Os percentuais de perdas na fenação não diferiram entre os tratamentos, com níveis variando de 17,33 a 20,17%. Os fenos de milheto e sorgo sudanense tiveram as maiores concentrações de PB (10,56 e 8,80%), superiores às do capim-elefante (6,76%) e dos sorgos SF-25 (5,62%) e IPA-467-4-2 (5,50%). Os valores de FDN foram, na maioria, superiores a 70,0%. As menores concentrações de NIDN foram observadas nos cultivares de sorgo (0,42 e 0,40% da MS). As concentrações de NIDA variaram de 0,06 a 0,30% na MS. As maiores concentrações de lignina (%MS) dos fenos foram obtidas no milheto (6,52%) e no sorgo IPA-467-4-2 (6,17%). As concentrações de nutrientes digestíveis totais estimadas (NDTe) dos fenos diferiram significativamente, com o maior valor para o sorgo sudanense (53,35%). Os fenos triturados das gramíneas tropicais avaliadas apresentaram rendimentos elevados e composição químico-bromatológica dentro dos padrões mínimos recomendáveis para nutrição de ruminantes.The research was carried out to evaluate yield, chemical composition and losses of chopped tropical grass hays with the following forages: pearl millet (Pennisetum americanum), sudangrass (Sorghum sudanense), elephantgrass (Pennisetum purpureum) and two cultivars of forage sorghum (SF-25 and IPA-467-4-2) (Sorghum bicolor). The materials were harvested at 30% flowering, except for elephantgrass (60 days). The experiment was conducted according to a complete randomized block design, with five treatments and four replications. There were significant differences among hay productions with sorghum cultivars IPA-467-4-2 and SF-25 reaching the highest yields (10.85 and 10.65 t/ha/cut). Production of elephantgrass, sudangrass and pearl millet hays were respectively of 6.94, 6.69, and 4.93 t/ha/cut. Percentage of hay losses were not different among all treatments and varied from 17.33 to 20.17%. Pearl millet and sudangrass hays had the highest CP concentrations (10.56 and 8.80%), which were superior to elephantgrass (6.76%) and sorghum cultivars (5.62 and 5.50%). Most of the NDF values were superior to 70.0%. Sorghum cultivars exhibited the lowest NDIN concentration (0.42 and 0.40% of DM). The ADIN concentration ranged from 0.06 to 0.30% of DM. The highest lignin (%DM) concentration was observed for pearl millet (6.52%) and sorghum IPA-467-4-2 (6.17%) hays. Estimated TDN of the hays showed significant differences and sudangrass reached the highest value (53.35%). Production of chopped tropical grass hays showed high yields and chemical composition according to the minimum standards for ruminant nutrition.

O mercado brasileiro de flores e plantas ornamentais apresenta-se com perspectivas de crescimento e conseqüente incremento para os principais segmentos da cadeia produtiva: produção, distribuição e comercialização. Esta previsão, bastante otimista, vem atraindo para o setor novos empreendedores, com conseqüente aumento da concorrência e a constante necessidade da busca por novos produtos e serviços. Com o objetivo de compreender a nova tendência da cadeia de flores e plantas ornamentais e de avaliar a estrutura do segmento varejista no município de Lavras (MG), realizou-se um levantamento de informações junto aos estabelecimentos que comercializam flores e plantas ornamentais, no primeiro semestre de 2003. Para tanto, utilizou-se de uma pesquisa de caráter exploratório, com perguntas voltadas à estrutura operacional da empresa, além de questões sociais sobre o florista, podendo-se citar o nível de conhecimento na área e preocupação com atualização. No município não há estabelecimentos com auto-serviço de flores e plantas ornamentais, apenas floriculturas comerciais, que totalizam 11 estabelecimentos, dentre os quais, 64% realizam projetos paisagísticos, 73% oferecem trabalhos de jardinagem, e 45% possuem produção própria, sendo que esta se caracteriza, de modo geral, por plantios protegidos em pequenas áreas, voltados para o próprio abastecimento, apenas com cultivos orgânicos, simplificados, de mudas para jardim. Assim, todos dependem do fornecimento regular de plantas, em sua maioria realizado diretamente por grandes atacadistas, ponto a ponto. De maneira geral, observou-se que os varejistas limitam-se à participação na disputa de preços, mostrando-se preocupados com os altos níveis de competitividade em que o mercado encontra-se e menos interessados na diversificação dos produtos e serviços e estratégias de marketing. Por outro lado, há poucos comerciantes voltados para a oferta de produtos com valores agregados e inovadores, buscando maiores margens. Pode-se inferir que isto se deve ao tempo de atuação no mercado, uma vez que 64% das empresas possuem mais de 6 anos, enquanto as outras 36% atuam há menos de 3 anos. Um dos principais problemas informados pelos comerciantes locais é a concorrência com vendedores ambulantes de plantas. Devido, em parte, à competitividade no segmento, não se observa interação entre os floristas, excluindo-se assim, a possibilidade de uma integração produtiva, a qual, entre outras vantagens, poderia proporcionar melhor estruturação do setor.Ornamentals plants and flowers Brazilian market has been presenting increase perspectives and consequent increment for the main segments of productive system: production, distribution and commercialization. This optimist prevision has been attracting new undertakes occasioning an increase of competition and the search necessity for new products and services. To understand the ornamental plants and flower new tendency and to analyze the retail segment structure at Lavras County, State of Minas Gerais, Brazil, that was the main purpose of this work, were got information at the flower and ornamental plants establishments at the first semester of 2003. For this porpose, was made an exploratory research with questions about the enterprise operational structure and social questions about the florists, like knowledge level in the area and their concern about to be up to date. In the county there aren't cash and carrier flower's shops, only commercial floriculturist, among them 64% work with landscape design projects, 73% offer gardening works, and 45% have self-production, being characterized generally by protected planting in small areas and only organic and simplified cultivation of garden's seedlings for self-provisions. Therefore, at the majority all florists depend on regular plants supply accomplished directly by large wholesaler, store to store. In general, it was observed that the retailers are limited in the price dispute showing their concern with the market competition high levels, and fewer interested in the productions and services diversification. Moreover, there are few sellers that offer innovation of products and services with aggregated value, searching for highest margins. This can be the result from the time of the floricultures at the market, once that 64% of the enterprises have more than 6 years, while the others 36% have fewer than 3 years. One of the main problems informed by the local florists is the competition of the door-to-door plant's salesmen. Due to the competitiveness of the segment, there isn't florist interaction excluding a productive integration possibility that can afford a better sector organization among others advantages.

A queda prematura dos frutos cítricos (QPFC), causada por Colletotrichum acutatum, dados os grandes prejuízos que têm causado aos produtores, constitui-se numa doença de grande importância econômica. O controle da doença é feito predominantemente mediante uso de fungicidas, que eleva o custo de produção e afeta negativamente o meio ambiente. Diante disso, este trabalho teve por objetivo buscar um método alternativo de controle da QPFC, mediante o uso de agentes de biocontrole ou de biofertilizantes. Diferentes concentrações de biofertilizantes (originários de duas fontes distintas e denominados de Bio1 e Bio 2); três isolados de Bacillus subtilis (ACB-69; 72 e 77) e três isolados de Trichoderma spp. (ACB-14; 37 e 39) foram testados, isoladamente ou em combinação, sob condições de laboratório, quanto à capacidade inibitória da germinação de conídios de C. acutatum. Estudaram-se, ainda, a produção de metabólitos termoestáveis por B. subtilis e o efeito sobre a germinação do patógeno. Quinze isolados de B. subtilis foram testados quanto à capacidade de prevenir a infecção por C. acutatum em flores destacadas de lima- ácida 'Tahiti' e, no campo, foram instalados dois experimentos, visando a testar ACBs e biofertilizantes no controle da doença. Verificou-se que o isolado ACB-72 (B. subtilis) e ACB-37 (T. pseudokoningii) foram os que mais inibiram a germinação do patógeno. Quanto à produção de metabólitos termoestáveis, ACB-69 e 77 foram os mais eficientes em produzir substâncias antifúngicas, e em quantidades suficientes para inibirem a germinação do patógeno. A mistura dos quatro isolados de Bacillus (ACBs: 69; 72; 77 e AP3) foi o que apresentou maior porcentagem de inibição (73%). Os biofertilizantes (Bio1 e Bio2), em concentrações acima de 10% e, quando em associação com isolados de Trichoderma spp., promoveram maiores inibições na germinação de C. acutatum. Em testes com flores destacadas, verificou-se que, onde foram aplicados os ACBs 69; 76; 74 e 77, as porcentagens de pétalas sem sintomas de infecção por C. acutatum foram de 83; 92; 92 e 97%, respectivamente. Mediante avaliações a campo, verificou-se a potencialidade de B. subtilis e de biofertilizantes em controlar a doença.Postbloom Fruit Drop of Citrus (PDF), caused by Colletotrichum acutatum, has caused losses to citrus producers and therefore it is economically very important. This disease is generally controlled by fungicide sprayings, which increase the production cost, and affects the environment. Thus, this work aimed at developing an alternative control method through the use of biocontrol agents, or biofertilizers. Different concentrations of biofertilizers (from two distinct sources and named Bio1 and Bio2), three strains of Bacillus subitlis (BCA-69, 72 and 77) and three isolates of Trichoderma spp. (BCA-14, 37 and 39) were tested, in vitro, alone or in combination, for the inhibitory capacity of conidia germination of C. acutatum. It was studied the production of thermo-stable metabolites by B. subtilis and their effect on the germination of C. acutatum conidia. Under in vivo conditions, 15 isolates of B. subtilis were tested for the ability to prevent C. acutatum infection on 'Tahiti' lime detached flowers and in the field, where two experiments were installed, for testing the BCA and biofertilizers in the control of the disease. It was found that the isolate BCA-72 (B. subtilis) and BCA-37 (T. pseudokoningii) were the most efficient in inhibiting conidia germination. BCA69 and BCA-77 were the most effective in producing anti-fungal substances, and in quantities sufficient to inhibit the germination of C. acutatum. The mixture of four strains of Bacillus (BCA: 69, 72, 77 and AP3) presented the highest percentage of inhibition (73%). Regarding the use of biofertilizers (Bio1 and Bio2), it was observed that concentrations above 10% of the product, when combined with the strains of Trichoderma spp. decreased the pathogen germination. The experiments with detached flowers showed that the flowers where the BCA: 69, 76, 74 and 77 were applied presented 83, 92, 92 and 97% respectively, of the petals without symptoms of infection by C. acutatum. Field tests showed the potential of B. subtilis and biofertilizers in controlling the disease.

O objetivo deste trabalho foi avaliar a dinâmica de decomposição e a liberação de nutrientes da parte aérea de plantas de soja cultivar Celeste, para fins de adubação verde. Utilizou-se o delineamento experimental de blocos ao acaso com cinco repetições. Nas parcelas, as plantas foram cortadas rente ao solo aos 55, 85 e 115 dias após a emergência (DAE) e foram analisadas quanto à decomposição do material vegetal e liberação de N, P, K, Ca e Mg, colocando-se 60 g de matéria fresca da parte aérea em sacos de tela, distribuídos sobre a superfície das parcelas no campo. Nas subparcelas, as taxas de redução de massa de matéria seca e de liberação de nutrientes foram monitoradas mediante análises aos 5, 10, 15, 30, 60, 90, 120 e 150 dias após os cortes das plantas. O modelo exponencial X = X0e-kt demonstrou dinâmicas não muito contrastantes, para os materiais cortados aos 55, 85 e 115 DAE. Apesar de o clima possivelmente ter influenciado na liberação de K, não causou diferenças significativas na decomposição de matéria seca e na liberação de N e fósforo. As plantas de soja, cortadas em diferentes estádios de desenvolvimento, apresentam taxas similares de decomposição e de liberação de nutrientes.The objective of this work was to evaluate the dynamics of decomposition and release of nutrients from aerial plant parts of the soybean cultivar Celeste used as green manure. A randomized block design was adopted with five replications. Soybean plants were cut close to the soil surface 55, 85 and 115 days after emergency (DAE), and analysed to determine their decomposition and release of N, P, K, Ca and Mg, by placing 60 g of fresh material of the aerial part in nylon screen bags, that were distributed on field plots surface . The rates of loss of dry matter and of nutrient release were monitored in the 5, 10, 15, 30, 60, 90, 120 and 150 days after plant cut. The exponential model X = X0e-kt demonstrated that the dynamics of the material cut in the 55, 85 and 115 DAE were not so contrasting. The climate could have interfered on the results, principally on K release rates, however it did not cause mean differences on the biomass decomposition and N and P release. Soybean plant material from cut plants, at different growth stages, present similar rates of decomposition and nutrient release.

A quantificação do carbono nas diferentes frações da matéria orgânica do solo (MOS) torna-se necessária devido ao interesse de se conhecer o potencial de captura e armazenamento do carbono nos diferentes sistemas de uso do solo. O objetivo deste trabalho foi quantificar o carbono das substâncias húmicas em diferentes sistemas de uso do solo e épocas de avaliação e correlacioná-lo com algumas propriedades químicas e físicas do solo. Os sistemas selecionados foram: preparo convencional (PC-milho/feijão), plantio direto (PD-berinjela/milho), consórcio maracujá/Desmodium sp, cultivo com figo e sistema agroflorestal. As amostras de solo foram coletadas em duas profundidades (0-5 e 5-10 cm) e épocas (17/11/2005-verão e 23/6/2006-inverno). Foi determinado o carbono orgânico total (COT) e realizado o fracionamento químico da MOS, quantificando-se o carbono da fração humina (C-HUM), fração ácido húmico (C-FAH) e fração ácido fúlvico (C-FAF). O C-HUM constituiu a maior parte do COT, havendo correlação significativa com o COT em todos os sistemas avaliados e estações. Analisando o C-FAH foi possível identificar alterações no solo relacionadas aos sistemas de uso, na profundidade de 0-5 cm e no verão, destacando-se o PD com os maiores teores. Com o C-FAF ocorreu este mesmo comportamento, mas na profundidade de 5-10 cm e no inverno, destacando-se o PC com maiores valores. Foram verificadas correlações significativas entre Valor S, Valor T e DMP em todos os sistemas, com exceção da área de PC. O PD aumenta os teores de C-FAH, nas duas profundidades e nas duas estações, quando comparado ao PC do solo.

O laser de baixa potência vem sendo usado para acelerar a cicatrização em úlceras de pressão devido a seus efeitos cicatrizante, antiinflamatório, antiedematoso e analgésico. No entanto, não há consenso quanto a seu efeito em úlceras infectadas. O objetivo deste estudo foi verificar o efeito bactericida da laserterapia e da terapia fotodinâmica (TFD) com laser de baixa potência, InGaP, 670 nm, em doses de 2, 4 e 6 J/cm², em bactérias gram-positivas e gram-negativas in vitro. Foram preparadas 32 placas de Petri com bactérias, 16 com Pseudomonas aeruginosa e 16 com Staphilococcus aureus. Aleatoriamente dividiu-se cada grupo em oito subgrupos (duas placas cada): três subgrupos tratados só com laserterapia, em doses de 2 J/cm², 4 J/cm² e 6 J/cm²; três subgrupos tratados com TFD, em doses de 2 J/cm², 4 J/cm² e 6 J/cm²; um tratado apenas com fotossensibilizante (azul de metileno a 0,1 µg/ml); e um subgrupo não tratado (controle). Os subgrupos laser e TFD foram irradiados uma única vez e incubados por 24 horas. Os outros dois subgrupos não receberam irradiação. As culturas foram analisadas visualmente para verificação ou não do halo de inibição. Em todos os subgrupos, de ambas as bactérias, não foi observado qualquer halo de inibição nem de crescimento. Conclui-se que a terapia a laser e a fotodinâmica de baixa potência (InGaP, 670 nm) não produziram efeitos bactericidas e/ou bacteriostáticos, tampouco tendo havido efeito bioestimulante sobre as bactérias.Low-level laser therapy has been used to speed up healing process of pressure ulcers due to its antiinflammatory, analgesic, anti-edematous, and scarring effects. However there is no consensus on its effect on infected ulcers. The aim of this study was to verify the bactericidal effect of low-level laser therapy (InGaP, 670 nm) and photodynamic therapy (PDT) at 2, 4 and 6 J/cm² doses, onto gram-negative and gram-positive bacteria in vitro. Thirty two Petri plates were prepared, 16 with Pseudomonas aeruginosa and 16 with Staphilococcus aureus, and divided into eight subgroups each: three subgroups treated with 2 J/cm², 4 J/cm², and 6 J/cm² laser; three subgroups treated with 2 J/cm², 4 J/cm², and 6 J/cm² PDT; one treated solely with photosensitiser; and a non-treated (control) subgroup. Laser and PDT groups were irradiated once and incubated for 24 hours; the other two subgroups underwent no irradiation. Cultures were visually analysed in search of inhibition haloes. In all subgroups, for both bacteria, no inhibition or growing signs could be detected. Hence neither low-level laser or PDT (InGaP, 670 nm) produced any bactericidal or bacteriostatic effect, nor any biostimulation effect, onto analysed bacteria.

Socio-economic perspectives of family farming in South America: cases of Bolivia, Colombia and Peru

Description
An account of the resource
Family farming is very important because it is, among other types, the principal source of food and employment, especially in developing countries. Given the constant changes in the agrarian structure and environment, what are the prospects of family farming under current conditions in South America? To answer this question, we have chosen three countries from this continent: Bolivia, Colombia, and Peru. Based on a literature review of case studies in each country, a comparative analysis of the following topics was carried out: purpose of family farming, production unit, and agricultural production, integration with the market, income, and food security. Many similarities were found in the studied countries, which allow for some generalizations in certain aspects related to the studied cases. Family farming is largely moving to the rhythm of the markets. Its transition from a condition of subsistence to commercial status depends mainly on the availability of sufficient resources for production: mainly land, labor, and financial capital. The scarcity of these resources is forcing farming families to seek other sources of income or to migrate. The monetization of farming is increasing.

Description
An account of the resource
Environmental issue such as global warming become highlight issue in the world. Some environmental issue pointed out as the effect of consumer behavioural which ignored the effect of purchasing to the environmental conservation. For this time environmental issue becoming the important factor for consumer in considering product choosing, even in choosing diapers. This study aims to examine the influence of value orientations on ecological knowledge and ecological affect. This research also aims to investigate the influence of ecological knowledge on ecological affect, also to investigate the influence of ecological knowledge, ecological affect, internal locus of control on green purchase intention. Sampling method is nonprobability sampling with purposive sampling. Data were collected using a questionnaire survey. The sample in this study consisted of 229 women aged over 17 years old and who have children aged 0 to 24 months in Yogyakarta. The study was based on confirmatory model. Structural equation modeling (SEM) by using AMOS statistical program used to test validity and reliability of the instrument, the goodness of fit model and the relationship hypothesized in the theoretical model proposed. Findings from structural models have proved nearly all the hypothesized relationships. This study reveals that value orientations has a positive effect on ecological knowledge but the effect of value orientations on ecological affect is not supported. Ecological knowledge has a positive effect on ecological affect. Ecological knowledge and internal locus of control has a positive effect on green purchase intention, but the effect of ecological affect on green purchase intentions is not supported.

Description
An account of the resource
Objetivo: analizar las características del contexto que están impulsando la adopción de un enfoque circular en los nuevos modelos de negocio, reconociendo el papel fundamental que juega el consumidor en esta tendencia. Diseño metodológico: se basó en la revisión de artículos, informes y blogs que exponen el debate de la economía circular, se consultaron encuestas publicadas sobre el comportamiento de los consumidores. Para el análisis se identificaron las características que explican las tendencias y los patrones que inciden en la decisión de comprar en empresas con modelos sustentables y circulares. Resultados: se constata que los consumidores, en particular las generaciones jóvenes, son altamente sensibles a la narrativa de la crisis ambiental y a las tendencias que surgen en las redes llevándolos a adoptar estilos de vida que definen su decisión de compra, lo cual ha influido como un elemento determinante en la transición de los negocios hacia modelos sustentables y de economía circular. Limitaciones de la investigación: insuficiente información al ser un tema relativamente nuevo, los casos que se encuentran están dispersos y poco sistematizados. Hallazgos: la edad de los consumidores es clave para las decisiones de compra, los jóvenes son los que principalmente optan por alternativas de productos sustentables al ser más susceptibles a la influencia del discurso predominante y a la opinión de otros consumidores en las redes. Las empresas están realizando cambios en sus modelos para transitar hacia la economía circular, en atención a estos nuevos consumidores.
