Much is known about growth and nutrient uptake traits ecological stoichiometry in natural systems. However, these concepts have been comparatively understudied agricultural systems despite their potential to infer limitation interspecific resource competition. This study established a model mixed pasture system assess tissue C:N C:P aboveground biomass (AGB) grass (Phalaris aquatica) legume (Tr...

An experiment was conducted using a [6, 6-H]glucose isotope dilution method to determine the effects of plantain (Plantago lanceolata L.) on plasma glucose metabolism in sheep taken from a thermoneutral environment and exposed to a hot environment. The sheep were fed either mixed hay (MH) of orchardgrass (Dactylis glomerata L.) and reed canarygrass (Phalaris arundinacea L.) at a 60:40 ratio or ...

Four weed species (Bromus mollis, Vulpia sp., Poa annua, Steltaria media) occur in 30% or more of all perennial ryegrass seed samples. Of the listed undesirable species, Avena fatua (wild oat) and Hordeum murinum occurred respectively in 5.3 and 3.5% of ryegrass seedlots. Only 6 herbicides are registered for use in grass seed crops in New Zealand, 2 for wild oat, and 4 for broadleaved weeds. Th...

An isotope dilution method using [1-(13)C]sodium (Na) acetate was conducted to determine the effect of feeding hop (Humulus lupulus L.) residues on plasma acetate metabolism in six adult crossbred sheep. The sheep were fed 63 g/kg BW(0.75)/d of either mixed hay (MH-diet) of orchardgrass (Dactylis glomerata L.) and reed canarygrass (Phalaris arundinacea L.) at a 60:40 ratio or MH-diet and hop-re...

Auxins, mainly indole-3-acetic acid (IAA), play a critical role in numerous plant growth processes, including embryo development, root and flower development, vascular differentiation, stem elongation, apical dominance, and tropic responses. Charles Darwin and his son Francis performed some of the earliest work relating to the effect of auxin on plant growth with their experiments on phototropi...

Wheat (Triticum aestivum) is a globally significant crop and staple food for millions of people. Weed infestation one the major constraints affecting wheat productivity worldwide. The purpose this study was to assess efficiency Carfentrazone ethyl 5% + Clodinafop propargyl 15% DF as post-emergence herbicide against predominant weeds in crops. constraint productivity. conducted using Randomized ...
