A comparison of establishment methods of permanent pasture into an undeveloped depleted tussock grassland : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours, Lincoln University
(Lincoln University, 2007)
This research compared pasture establishment, with or without cultivation, with two drill types, Cross Slot or triple disc and with 0, 2 or 6 t ha ⁻¹ of lime in an herbicided, undeveloped depleted tussock grassland, at ...
Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser on gorse establishment was monitored over 23 months in land converted from pine forest to a dryland sheep pasture. There were fewer gorse plants in ...
Agronomic potential of Lupinus polyphyllus L. for dryland Merino properties in the Mackenzie Basin : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
This research examined the potential of Lupinus polyphyllus L. (also known in New Zealand as perennial lupin and Russell lupin) as a productive pasture component for high-country pastures. To do this, a combination of ...
Diurnal concentration of urinary nitrogen and rumen ammonia are modified by timing and mass of herbage allocation
The objective of this work was to evaluate whether changes in time of herbage allocation and herbage mass (HM) (low (L) or medium (M)) modify the diurnal pattern of urinary nitrogen (N) concentration and ruminal ammonia ...
Can alternative forages substantially reduce N leaching? Findings from a review and associated modelling
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2019-11-13)
Nitrogen (N) leaching losses from grazed pasture systems pose a risk to the environment with mitigation strategies urgently required to achieve regulatory limits. There has been increased interest in alternative forages ...
Role of wind and other meteorological factors in evaporation and potential evapotranspiration : a dissertation submitted in partial fulfilment for the requirements of Post Graduate Diploma in Agricultural Science in the University of Canterbury [Lincoln College], New Zealand
(Lincoln College, University of Canterbury, 1979)
The purpose of this study was to apply the Penman and the Thornthwaite formula for estimating potential evapotranspiration and checked with the estimates based on pan evaporation data to present the role of north-westerly ...
