Morfogênese do capim-marandu e de híbridos de Urochloa durante o período de diferimento
No full textTrabalho de Conclusão de Curso (Graduação)O diferimento da pastagem é uma estratégia relativamente simples e de baixo custo operacional, que permite a obtenção de pasto para alimentação dos animais no inverno. A escolha da planta forrageira apropriada para o diferimento é importante para obtenção de pasto diferido em quantidade e qualidade. Nesse contexto, um experimento foi conduzido no Setor de Forragicultura da Universidade Federal de Uberlândia, em Uberlândia, MG, de agosto de 2019 a junho de 2020. Objetivou-se comparar as características morfogênicas e estruturais de perfilhos da Urochloa brizantha cv. Marandu (capim-marandu) e de três híbridos atualmente disponíveis no mercado (capins Mulato II, Mavuno e Ipyporã) durante o período de diferimento. O período de diferimento foi de 90 dias, de março a junho de 2020. As variáveis de Número de Folha Viva, Número de Folha Morta, Comprimento do Colmo, Taxa de Aparecimento Foliar e Duração de Vida da Folha não tiveram diferença estatística. No entanto, a Taxa Alongamento Foliar e Comprimento Lâmina Foliar foram maiores para o capim-mavuno e capim-marandu, no entanto o capim-ipyporã apresentou menor CLF. A TAlC foi maior para capim-mavuno, menor para o capim-mulato 2 e intermediária para o capim-marandu. Dentre as gramíneas avaliadas, o capim-marandu se destaca como apropriada para uso sob diferimento na região de Uberlândia
The sward height at the early stockpiling period modifies the structural characteristics of marandu palisadegrass under continuous stocking
No full textThe control of sward height at the early stockpiling period influences the structural characteristics of stockpiled sward in winter. So, we conducted this work on the Cerrado region of Brazil based on the hypothesis that the reduction of pasture height at the beginning of stockpiling period results in: (i) lower stock of forage mass; and (ii) higher live leaf mass, but lower stem mass in stockpiled pasture during the winter. The treatments were four sward heights (15, 25, 35, and 45 cm) at early stockpiling period of marandu palisadegrass (Brachiaria brizantha syn. Urochloa brizantha cv. Marandu). The experiment was conducted in a completely randomized design, with three replications (paddocks with 800 m²). The stockpiled swards were evaluated during the grazing period in winter on days 7 (beginning), 45 (middle) and 90 (end). The vegetative tiller number (VEGT), live leaf mass (LLM) and leaf area index (LAI) were greater in the 15 cm stockpiled pasture than the other treatments. Greater heights (35 and 45 cm) at stockpiling resulted in greater forage mass than lower heights (15 and 25 cm). The VEGT, LLM, number of reproductive tillers, live stem mass, forage mass and LAI values were higher at the beginning than at the end of the grazing period. Our hypothesis has been proven, so that the reduction of sward height of the marandu palisadegrass at the beginning of the stockpiling period results in lesser forage mass, but with better structural characteristics.O controle da altura do pasto no período inicial de diferimento influencia as características estruturais do pasto no inverno, o que afeta o desempenho dos animais. Assim, realizamos este trabalho na região do Cerrado do Brasil para testar a seguinte hipótese: a redução da altura do pasto no início do período de estocagem resulta em um menor estoque de massa de forragem, no entanto, melhora as características estruturais do pasto armazenado no inverno. Os tratamentos foram quatro alturas de pasto (15, 25, 35 e 45 cm) no início do período de diferimento do capim-marandu (Brachiaria brizantha cv. Marandu). O experimento foi conduzido em delineamento inteiramente casualizado, com três repetições (piquetes com 800 m²). As pastagens armazenadas foram avaliadas durante o período de pastejo no inverno nos dias 7 (início), 45 (meio) e 90 (final). O número de perfilhos vegetativos (VEGT), a massa foliar viva (MFV) e o índice de área foliar (IAF) foram maiores no pasto de 15 cm do que nos demais tratamentos. Maiores alturas (35 e 45 cm) no armazenamento resultaram em maior massa de forragem do que alturas mais baixas (15 e 25 cm). Os valores de VEGT, MFV, número de perfilhos reprodutivos (REPT), massa viva do caule, massa forrageira e IAF foram maiores no início do que no final do pastejo. Nossa hipótese foi comprovada, de modo que a redução da altura da pastagem de capim-marandu no início do período de armazenamento resulta em menor massa de forragem, mas com melhores características estruturais
The use of light-transparent acetate sheet to measure canopy height of marandu palisadegrass: the influence of development stage and sward height
No full textThe use of light-transparent acetate sheet (LAS) may generate variations in the height measured in the sward. However, we compared the use or non-use of LAS to measure the average sward height of marandu palisadegrass (Urochloa brizantha syn. Brachiaria brizantha cv. Marandu) pastures. In the first experiment, the methods were applied in pastures with different average heights (15, 25, 35, and 45 cm), managed under continuous stocking with sheep, and with predominance of vegetative tillers. The shorter pastures (15 and 25 cm) had similar heights with or without the use of the LAS. However, in the taller pastures (35 and 45 cm), the use of LAS resulted in lower height values, compared with its absence. In the second experiment, we compared both methods for measuring the height of deferred marandu palisadegrass and fertilized with two nitrogen levels (50 and 200 kg ha-1) and with high presence of reproductive tillers. A completely randomized design with four replicates was adopted. With 200 kg ha-1 of N, the canopy height was greater than when it was fertilized with 50 kg ha-1 of N. With the use of LAS, the height of deferred and reproductive canopy was greater than without it. In a taller marandu palisadegrass pasture with predominance of vegetative tillers, the use of LAS results in smaller height, contrary to what occurs in deferred swards with reproductive tillers.O uso da lâmina de acetato leve e transparente (LALT) pode gerar variações na altura medida no pasto. Assim, comparamos o uso ou não do LALT para medir a altura média do pasto de capim-marandu (Urochloa brizantha syn. Brachiaria brizantha cv. Marandu). No primeiro experimento, os métodos foram empregados em pastos com diferentes alturas médias (15, 25, 35 e 45 cm), manejados sob lotação contínua com ovinos e com predominância de perfilhos vegetativos. Os pastos mais baixos (15 e 25 cm) apresentaram alturas semelhantes, com ou sem o uso da LALT. No entanto, nos pastos mais altos (35 e 45 cm), o uso do LALT resultou em menores valores de altura, em comparação com a sua ausência. No segundo experimento, comparamos os dois métodos para medir a altura do capim-marandu diferido e fertilizado com dois níveis de nitrogênio (50 e 200 kg ha-1) e com alta presença de perfilhos reprodutivos. O delineamento experimental foi o inteiramente casualizado, com quatro repetições. Com 200 kg ha-1 de N, a altura do dossel foi maior do que quando foi fertilizado com 50 kg ha-1 de N. Com o uso de LALT, a altura do dossel diferido e em estádio reprodutivo foi maior do que sem ela. Em pastos de capim-marandu mais altos e com predominância de perfilhos vegetativos, o uso de LALT resulta em menor altura, ao contrário do que ocorre em pastos diferidos e com perfilhos reprodutivos
The fellowship of St.Diogo : new Christian judaisers in Coimbra in the early 17th century
No full textDr Antonio Homem was a respected teacher in the University of Coimbra, a Canon in the Cathedral and an illustrious scholar. He was also the heir of a long Jewish family tradition. His great-great-grand father lived and died as a Jew. His great-grandfather, his grandmother and two of his uncles were among his relatives to have been sentenced
as judaisers by the Inquisition. His own father kept the Law of Moses, and taught it to all his children, without the knowledge of his wife, an Old Christian of noble lineage.
His concern for the situation of the New Christians in Portugal eventually made him build up a congregation of judaisers, which he called the Fellowship of St Diogo as a tribute to a Capuchin friar who had been executed a few years earlier as an apostate and defender of the Jewish Law. His congregation grew to include over sixty people,
including clerics, physicians, lawyers and students, as well as merchants and farmers. Its leader gave it a corpus of doctrine and eventually a distinctive liturgy, which showed influence from the Catholic Church. The Fellowship also inspired the creation of judaiser conventicles
in three major Monasteries in the Coimbra district, where a relatively large number of nuns held cult meetings and paid homage to Friar Diogo as a martyr of the Law of Moses.
After several years of activity, the Fellowship was investigated and dismantled by the Inquisition. Most of its members were arrested and sentenced. Dr AntOnio Homem was himself taken into custody, charged with heresy and apostasy, as well as sodomy (he was a known paederast), and finally handed over to the secular arm for execution.
His dream of building up a judaiser community in Coimbra was shattered. The Fellowship members who survived either left the country and joined the orthodox Jewish communities in the Netherlands and elsewhere, or stayed in Portugal and gradually lost their Jewish consciousness. Descendants
of some of them can still be found near Coimbra
