Invasive Andropogon gayanus (gamba grass) is an ecosystem transformer of nitrogen relations in Australian savanna.
Invasion by the African grass Andropogon gayanus is drastically altering the understory structure of oligotrophic savannas in tropical Australia. We compared nitrogen (N) relations and phenology of A. gayanus and native grasses to examine the impact of invasion on N cycling and to determine possible reasons for invasiveness of A. gayanus. Andropogon gayanus produced up to 10 and four times more...
متن کاملProduction, Nutritional Quality and In vitro Methane Production from Andropogon gayanus Grass Harvested at Different Maturities and Preserved as Hay or Silage
Andropogon gayanus is an important grass due to its high biomass production, drought tolerance and favorable growth on low fertility acidic soils. Currently, there is little research on the impact of growth stage on the nutritional quality or the degree of CH4 production that may arise from this forage during ruminal fermentation. The objectives of this study were to determine the effects of re...
متن کاملIn vitro Gas Production and Dry Matter Digestibility of Irradiated Pomegranate (Punica granatum) Seeds
The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...
متن کاملPrairiegrass–Brassica Hybrid Swards for Autumn Dry Matter Production
Stockpiling herbage can redistribute nutrient availability and supplement quantity for livestock, depending on production objectives. Brassicas (Brassica spp.) and improved prairiegrass (Bromus catharticus Vahl.) cultivars are adapted to growing conditions occurring in the Appalachian region and provide nutritionally valuable herbage in autumn; however, highly digestible brassica herbage may re...
متن کاملModelling Dry Matter Production and Partitioning in Sweet Pepper
Models predicting growth and yield have been developed for a large number of crops. This paper describes a dynamic, mechanistic model for sweet pepper, addressing issues such as leaf area expansion, dry matter partitioning and validation. Leaf area formation and organ initiation are simulated as a function of temperature sum. Light absorption and photosynthesis are calculated for a multilayered...
