The largest contributor to nitrogen (N) leaching from ryegrass-clover pasture based dairy
farms is the surplus feed N excreted as urinary N (UN) onto pastures. Pastures consisting of …

Economic values (EVs) are an estimate of the change in farm system profit per unit of change
in a defined plant trait. Cultivars within species such as perennial ryegrass differ in the …

The growing importance of fodder beet (Beta vulgaris subsp. vulgaris var. alba L.) as stock
feed in recent years has created the need to develop a crop model to help assess crop yield …

This study tested the hypotheses that: (i) genetic variation in Rubisco turnover may exist in
perennial ryegrass (Lolium perenne L.); (ii) such variation might affect nitrogen use efficiency …

Despite the importance of roots in determining plant performance, the factors controlling
their development and longevity remain poorly understood. Grass morphology is based on …

BACKGROUND Nitrogen (N) fertiliser used on crops is among the main sources of water
pollution. Reliable measurement of N losses from land uses in catchments is key to designing …

Two fodder beet (Beta vulgaris L.) cultivars (‘Rivage’ and SF Brigadier™) were evaluated in
a field experiment to quantify the effect of cultivar and sowing date on growth physiology. …

Chicory (Cichorium intybus L.) crops can increase milk production on New Zealand dairy
farms through providing high-quality feed in late lactation. Non-linear optimization models of …

Fodder beet has become a popular winter feed for all stock classes in New Zealand. However,
poor crop establishment frequently leads to either significant loss in yield, through below-…

The Simple Crop Resource Uptake Model operating within the Agricultural Production
Systems sIMulator (SCRUM-APSIM) was used to simulate nitrogen (N) leaching from crop …
