Neuroendocrine regulation of dry matter intake in grazing dairy cows
(Lincoln University, 2014)
Supplementary feeds are offered to grazing dairy cows to increase dry matter and metabolizable energy intakes; however, offering feed supplements reduces pasture dry matter intake, a phenomenon known as substitution. The ...
Factors affecting the response of thrips to an olfactory cue
(Lincoln University, 2013)
Some thrips (Order Thysanoptera) are key pests of many greenhouse and outdoor crops worldwide. Biological attributes such as polyphagy, rapid reproduction, cryptic behaviour and insecticide resistance make them particularly ...
Comparison of spray dose measured on leaf surfaces with spray coverage estimated from Kromekote® paper
(New Zealand Plant Protection Society Inc, 2015)
The control of tomato potato psyllid largely depends on effective application of pesticides. This paper presents an experiment to measure deposition using leaf washing of spray containing water and rhodamine dye on a potato ...
Endophytes in maize (Zea mays) in New Zealand
(Lincoln University, 2017-08-24)
The aim of this study was to isolate fungal endophytes from maize in New Zealand (NZ) and to select endophytes with potential to reduce insect pests and/or plant diseases. Culture methods were used to isolate 322 isolates ...
The effect of nitrogen on the yield of four pasture grass species
(Lincoln University, 2017-11-14)
This research examined the morpho-physiological attributes of four pasture grass species under two nitrogen (N) treatments. The experiment was a split plot design with main plots of N+ and N- and subplots of cocksfoot ...
Crop manipulation to improve hybrid radish seed yield and quality
(Lincoln University, 2018)
Hybrid radish (Raphanus sativus L.) seed is grown in New Zealand for multiplication and re-export, and radish seed exports were worth $22.8 million in 2017. Seed yields vary with hybrid and season, but are reduced by ...
Impacts of selecting sheep for resistance and resilience to gastro-intestinal nematode parasites
(Lincoln University, 2018)
This study investigated the impacts of decades of divergent selection for either resistance or resilience to gastrointestinal nematode (GIN) parasite infection in Romney sheep lines and involved a series of three studies.
Study ...
Modelling the temporal and spatial variation of evapotranspiration from irrigated pastures in Canterbury
(Lincoln University, 2015)
Evapotranspiration is a critical factor for local and regional planning, in terms of both water quality and quantity, to inform decisions around water catchment management, irrigation, water storage, and resource sustainability. ...
The ability of nitrogen fertilisers to break the lifecycle of gastro-intestinal nematodes
(Lincoln University, 2017)
Current gastrointestinal nematode (GIN) control relies heavily on chemical anthelmintic, targeting nematodes within the host ruminant. Most of the lifecycle occurs outside of the host so targeting the free-living population ...
A new pest management research facility: Scion’s large-scale precision track sprayer
(New Zealand Plant Protection Society (Inc), 2014)
A new large scale precision track sprayer has been developed and evaluated for spray deposition and pesticide application research under controlled conditions. The spray room is fitted with a 4 m wide electrically driven ...
