How does defoliation management impact on yield, canopy forming processes and light interception of lucerne (Medicago sativa L.) crops?
The frequency of defoliation is the major management tool that modulates shoot yield and the accumulation of C and N root reserves in lucerne crops. A fully irrigated, two year old lucerne (Medicago sativa L.) crop was ...
Accounting for the utilization of a N₂O mitigation tool in the IPCC inventory methodology for agricultural soils
(Springer Netherlands, 2007)
In this study we review recent studies where dicyandiamide was used as a nitrification inhibitor to reduce both N₂O emissions from urine patches and nitrate leaching from pasture systems, and which led to the development ...
Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes
(American Society of Agronomy, 2007)
The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects ...
Estimating values of environmental impacts of dairy farming in New Zealand
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2009)
New Zealand is the world’s largest exporter of dairy products, supplying about one third of global trade. The dairy sector strives to maintain international competitiveness by continued increases in productivity and ...
Defoliation frequency and season affected radiation use efficiency and dry matter partitioning to roots of lucerne (Medicago sativa L.) crops
Radiation use efficiency (RUE), and subsequent partitioning between shoots and roots were investigated for ‘Grasslands Kaituna’ lucerne crops grown in the cool temperate climate of Canterbury, New Zealand. Crops were ...
Quantifying the effect of nitrogen on productivity of cocksfoot (Dactylis glomerata L.) pastures
Inorganic nitrogen fertilisers are commonly applied to crops and pastures to increase or maintain productivity. The benefits of N application must be balanced with the potential for environmental damage. At Lincoln University, ...
