Intake studies in grazing beef and dairy cattle
(Lincoln College, University of Canterbury, 1969)
In recent years there has been a growing demand for increased levels of efficiency in the pastoral industry. To achieve this the efficiency of conversion of the individual animal must be measured by equating its level of ...
An evaluation of Ariki ryegrass under Canterbury conditions
(Lincoln College, University of Canterbury, 1965)
Following the success of Corkhill (1945) in producing short-rotation ryegrass (Lolium perenne x Lolium multiflorum) with controlled hybridisation and selection, the Plant Breeding Division of the D.S.I.R. (N.Z.) began a ...
The root symbioses of Alnus viridis (Chaix) DC
(Lincoln College, University of Canterbury, 1968)
The present investigations were initiated because an understanding of the symbioses of Alnus viridis will influence the use of this species in New Zealand. There are extensive areas in New Zealand where vegetation and ...
A study of foliar leaching of lucerne
(Lincoln College, University of Canterbury, 1967)
The work reported here is an evaluation of leaching losses from Medicago sativa. Lucerne plants subjected to rain, dew or mist lose nutrients by leaching, the extent of nutrient loss being influenced by a number of factors, ...
The effect of liveweight on ewe fertility
(Lincoln College, University of Canterbury, 1967)
The reproductive-performance of ewes is determined by ovulation and fertilisation rates and by the number of embryos which survive. However, many studies of the efficiency of reproduction or management concern traits which ...
An investigation of problems associated with the inoculation of soybeans (Glycine max (L.) Merrill) with Rhizobium japonicum (Kirchner) Buchanan
(Lincoln College, University of Canterbury, 1965)
If soybeans are to have a place in New Zealand farming, system, they must be grown economically, in terms of yield produced and costs of production. Inoculation with rhizobia will no doubt help to achieve this aim if the ...
An agronomic evaluation of subterranean clover cultivars
(Lincoln College, University of Canterbury, 1969)
The permanent pasture based on a grass-clover association and utilised in situ by grazing stock is the basis of New Zealand's chief primary industries. Although white
clover is the main legume species used for this purpose ...
An evaluation of recent advances in the use of anhydrous and aqueous ammonia overseas and their application in New Zealand horticulture
(Lincoln College, University of Canterbury, 1968)
The object of this study is to evaluate recent advances in the use of anhydrous and aqua ammonia as nitrogenous fertilisers, with emphasis on the prospects and needs there are for their usage in New Zealand. There is at ...
Some studies on the instrumentation of a single cylinder, spark ignition engine
(Lincoln College, University of Canterbury, 1967)
A project was undertaken to study the air metering and cylinder pressure measuring components of an instrumentation system for a single cylinder spark ignition demonstration engine. The overall problem of the selection of ...
A comparison of the lactation performaces between Romney, Corriedale and Merino ewes under high country conditions
(Lincoln College, University of Canterbury, 1966)
Factors which affect the growth of the lamb are of considerable economic importance in animal production. Most workers in this field have shown that growth rates are influenced to a large extent by milk production, especially ...
