(Lincoln University, 1999)
Argentine stem weevil (ASW) Listronotus bonariensis (Kuschel) is an introduced species that attacks improved graminaceous pasture and crop throughout much of New Zealand. It is recognised as the most important arthropod ...
The effects of foliar diseases and irrigation on root development, yield and yield components of wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1985)
Studies were conducted on three field trials of wheat cv. Kopara to investigate the lack of compensation by later determined components of yield because of early disease constraints. The investigation was based on the ...

The Western and Central Pacific Ocean (WCPO) is home to the largest tuna fishery stock in the world. However, Pacific Island members of the Western and Central Pacific Tuna Commission (WCPTC) argue that their share of the ...
Dynamics of ammonia volatilization and nitrous oxide production from urine patches in grazed pastures
(Lincoln College, University of Canterbury, 1984)
A continuously aspirated enclosure method was used to measure ammonia (NH₃) volatilization from simulated sheep urine patches in a perennial ryegrass (Lolium perenne) / white clover (Trifolium repens) pasture in the field ...

Mineral nitrogen (N) levels in natural grasslands of the world fluctuate in response to a range of environmental influences but are generally low with ammonium (NH₄-N) levels usually below 10 µg g⁻¹ soil and nitrate (NO₃-N) ...
Genotypic evaluation of Trifolium ambiguum
(Lincoln College, University of Canterbury, 1979)
A number of morphological, floral, rhizome, root and herbage characteristics were studied in order to describe genetic variation and environmental responses in T. ambiguum. From each of six lines, 30 genotypes were clonally ...

(Lincoln University, 2008)
This study explores the factors that influence the management of a protected area situated on private land as well as the implications of these factors in the interaction between the NGO and the communities associated with ...
Nitrogen fixation in peas (Pisum sativum)
(Lincoln College, University of Canterbury, 1983)
Field experiments were conducted at Lincoln College, Canterbury, from 1979-81 to assess the effect of peas (pisum sativum) on subsequent crops and evaluate factors influencing their N-fixing activity.
In two trials, ...
