Morfogênese e dinâmica do acúmulo de forragem em capim-elefante cv. Napier submetido a alturas de resíduo pós-pastejo / Morphogenesis and dynamics of forage accumulation in elephant grass cv. Napier submitted to residual post-grazing heights

Sousa, Braulio Maia de Lana 03 1900 (has links)
No período de fevereiro a maio de 2009 (experimento 1) e dezembro de 2009 a maio de 2010 (experimento 2) foram avaliados os efeitos de três alturas pós-pastejo (30, 50 e 70 cm) sobre as características morfogênicas e estruturais e a dinâmica do acúmulo de forragem e dos componentes morfológicos em pastos de capim-elefante cv. Napier quando atingidos 95% de interceptação luminosa pelo dossel durante a rebrotação. O delineamento experimental foi o de blocos completos casualizados com três repetições. Nos dois experimentos e para perfilhos basais e aéreos e para o dossel, pastos manejados com altura pós-pastejo 30 cm apresentaram os menores valores de taxa de alongamento de folhas, duração de vida das folhas, taxa de alongamento de colmos, comprimento final da lâmina foliar e número de folhas vivas por perfilho. Esse padrão resultou em menores taxas de crescimento de folhas e de colmos, de crescimento total e de acúmulo de forragem nos pastos manejados com altura pós-pastejo de 30 cm relativamente àqueles manejados a 50 e 70 cm. As características morfogênicas e estruturais pouco diferiram entre as alturas pós-pastejo 50 e 70 cm. Contudo, pastos manejados a 50 cm apresentaram menores taxas de alongamento e de acúmulo de colmos e taxas de acúmulo de forragem relativamente estáveis, especialmente no experimento 2, em comparação àqueles manejados a 70 cm, sugerindo que essa altura pós-pastejo seria a mais indicada. A estratégia de decapitar a maioria dos meristemas apicais no primeiro pastejo (experimento 2) resultou em valores de características morfogênicas e estruturais relativamente mais estáveis e em menor taxa de acúmulo de colmos, sugerindo necessidade de controle minucioso da elevação dos meristemas apicais no primeiro ciclo de crescimento na primavera como forma de assegurar controle da estrutura dos pastos e produção de forragem com elevada proporção de folhas._________________________________________________________________________________________ ABSTRACT: From February to May in 2009 (experiment 1) and from December and May in 2010 (experiment 2) the effects of three post-grazing heights (30, 50, and 70 cm) on the morphogenetic and structural characteristics, and the dynamics of the forage accumulation and of the morphologic components were evaluated in pastures of Elephant grass cv. Napier when the sward reached 95% of light interception during regrowth. A complete randomized block design with three replications was used. In both experiments and for aerial and basal tillers, pastures managed with a 30 cm post-grazing height presented lower values of leaf appearance and elongation rates, of leaf lifespan, of stem elongation rate, of final leaf lamina length, and of number of live leaves per tiller. This pattern resulted in lower rates of growth of leaves and of stems, of total growth, and of forage accumulation in the pastures managed at a 30 cm post-grazing height relatively to the ones managed at 50 and 70 cm. The morphogenetic and structural characteristics slightly differ between the 50 and 70 cm post-grazing heights. Nevertheless, pastures managed at 50 cm presented the lowest rates of elongation and accumulation of stems and relatively stable rates of forage accumulation, especially in the experiment 2, in comparison to the ones manages at 70 cm, suggesting that this post-grazing height would be the most indicated one. The strategy of decapitating the majority of the apical meristems in the first grazing (experiment 2) resulted in relatively more stable values of morphogenetic and structural characteristics and in lower stem accumulation rates, suggesting the need for a thorough control of the elevation of the apical meristems in the first cycle of growth in the spring as a way of assuring the control of the structure of the pastures and forage production with elevated leaf proportion.

Target Cost and Quality Management in Kreditinstituten

Teetzmann, Eckart T. 16 April 2003 (has links)
Die Wettbewerbssituation hat sich für Banken in den vergangenen Jahren deutlich verschärft. Auf höhere Kundenerwartungen hinsichtlich Preis und Qualität, sowie auf steigende Betriebskosten müssen Banken mit einer klaren Kundenorientierung und einem effizienten Kostenmanagement reagieren. Das in der Arbeit dargestellte Konzept des Target Cost and Quality Management (TCQM) beruht auf den Grundüberlegungen des Target Costing, wird jedoch zu einem integrierten Instrument der Planung und Steuerung der Kosten und der Qualität von Bankleistungen ausgebaut bzw. adaptiert. In der Arbeit werden zunächst vor dem Hintergrund verschiedener Auffassungen in der Literatur bezüglich des Charakters und der Systematisierung von Bankleistungen das Verständnis der Bankleistung thematisiert. Im Anschluß daran werden die für das TCQM grundlegenden Konzepte des Target Costing und des Total Quality Management/Quality Banking erläutert und daraus ein grobes Phasenmodell des TCQM abgeleitet. Dieses Phasenmodell wird in einen strategischen Rahmen eingebettet. Nachfolgend wird, aufbauend auf einer allgemeinen Darstellung des Prozesses der marktorientierten Bankleistungs-/Prozeßgestaltung, die Festlegung von Preis-, Qualitäts- und Kostenzielen detailliert erläutert. Grundlage für eine marktgerechte Zieldefinition ist die Identifikation und Bewertung von Kundenanforderungen. Für den konkreten Einsatz der in der Arbeit dargestellten Instrumente und Methoden ist insbesondere die Differenzierung der Kundenanforderungen nach Basis-, Leistungs- und Begeisterungsanforderungen sowie nach merkmals- bzw. ereignisorientierten Anforderungen relevant. Mit Hilfe verschiedener, aufeinander abgestimmter Tabellen können dann konkrete Ziele abgeleitet werden. Den Ausführungen zur Zielfestlegung schließt sich eine Darstellung von Methoden zur Unterstützung der Zielerreichung an. Ein Schwerpunkt wird auf das bankspezifische Prozeßkostenmanagement aufgrund seiner erfolgskritischen Bedeutung für das TCQM gelegt.
