Yield and composition of lucerne strands in Central Otago after different winter grazing and weed control treatments
(New Zealand Grassland Association, 2014-12-01)
The effect of grazing date and time of spraying with a glyphosate/atrazine herbicide combination on a three year-old lucerne stand was studied on-farm in Central Otago. Total annual dry matter (DM) yield was highest in the ...
Integrating lucerne (Medicago sativa L.) into a high country merino system
(NZ Grasslands Association, 2014)
Farm systems in the dry sub-humid region of the Upper Waitaki predominantly graze merino ewes on extensive oversown and topdressed hill and high country. Smaller areas of flatter land are used to conserve winter forage ...
Understanding the role of spring grazing of lucerne in the Central Otago environment
(New Zealand Grassland Association., 2012)
The Lucerne for Lambs Sustainable Farming Fund
project used on-farm data and whole-farm modelling
to help farmers understand the impact of increasing
the amount of grazing dryland lucerne on Central
Otago farms. On-farm ...
Plant population, yield and water use of lucerne sown in autumn at four sowing rates.
(New Zealand Grassland Association., 2012)
Successful establishment of lucerne requires an adequate
plant population to maximise yield and maintain stand
persistence. The impact of autumn sowing lucerne
at four sowing rates was investigated in a split-plot
experiment ...
Growth and root : Shoot dry matter partitioning in seedling lucerne
(2012)
Sowing date affected shoot and root biomass yield in seedling lucerne.
Biomass partitioning to roots was influenced by photoperiod and water stress.
Modern lucerne management
(Lincoln University, 2012)
Predicting the transpiration of lucerne
(Elsevier B.V. on behalf of the European Society for Agronomy, 2012-11)
Crop transpiration rate is often predicted as the minimum of the supply of water from the roots and the demand for water from the shoots. A common method for predicting transpiration demand is the transpiration efficiency ...
Increased lucerne nodulation in acid soils with Sinorhizobium meliloti and lucerne tolerant to low pH and high aluminium
(CSIRO Publishing, 2018-10)
Acidic conditions with damaging levels of available aluminium (Al3+) currently limit lucerne (Medicago sativa) production on soils in the New Zealand high country and in large areas of Australia. Increased lucerne nodulation ...
On-farm comparision of pasture production in relation to rainfall in central Otago
(New Zealand Grassland Association, 2010)
Dry matter (DM) yields of unimproved resident
browntop-dominant pasture on three Central Otago
dryland farms was <1.5 t /ha/year from 2008-2010. An
intensive pasture renewal programme over >18 000
ha applied lime to increase ...
Soil pH, exchangeable aluminium and lucerne yield responses to lime in a South Island high country soil
(New Zealand Grassland Association, 2010)
A 2-year field experiment was conducted on a high
country brown stony soil in the Lees Valley, North
Canterbury. Two forms of lime (‘AgLime’ and
‘Quicklime’) were applied at 4 rates (0, 2, 4 and 8 t/
ha) and plots sown ...
