Growth strategy of rhizomatous and non-rhizomatous tall fescue populations in response to defoliation
The aim of this study was to determine the morphology of rhizome production, in two contrasting rhizomatous (R) and non-rhizomatous (NR) tall fescue (Schedonorus arundinaceus (Schreb.) Dumort) populations, and to assess ...
Sheep performance on perennial lupins at Sawdon Station, Lake Tekapo
A three-year trial compared the performance of Merino ewes grazing on a perennial lupin pasture with a control flock run predominantly on lucerne pastures at Sawdon Station, Lake Tekapo.
Phylogenetic and functional potential links pH and N₂O emissions in pasture soils
(Nature Publishing Group, 2016-10-26)
Denitrification is mediated by microbial, and physicochemical, processes leading to nitrogen loss via N₂O and N₂ emissions. Soil pH regulates the reduction of N₂O to N₂, however, it can also affect microbial community ...
Trichoderma strains suppress Rhizoctonia diseases and promote growth of potato
(Mediterranean Phytopathological Union, 2014)
Trichoderma spp. from New Zealand soils were evaluated (in greenhouse experiments and one field trial) for Rhizoctonia disease suppression and plant growth promotion of potato plants. Trichoderma virens LU549, T. atroviride ...
Intraspecific differences in long-term drought tolerance in perennial ryegrass
(Public Library of Science, 2018-04-04)
Lolium perenne L. (perennial ryegrass) is the most important pasture grass species in temperate regions of the world. However, its growth is restricted in summer dry environments. Germplasm screening can be used to identify ...
Milk yield and urinary-nitrogen excretion of dairy cows grazing forb pasture mixtures designed to reduce nitrogen leaching
The effect of including a mixture of forbs in a standard perennial ryegrass-white clover pasture, with or without Italian ryegrass was investigated in a two-period grazing study comparing urinary nitrogen (N) excretion and ...
Scarcity of ecosystem services: an experimental manipulation of declining pollination rates and its economic consequences for agriculture
Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional ...
