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 ...
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 ...
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 ...
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 ...
Delayed sowing decreased lucerne dry matter yield over two seasons
(New South Wales Department of Primary Industry, 2013-09)
Lucerne (Medicago sativa L.) can be sown in New Zealand from late spring (October) to early autumn (March). In the establishment season, greatest drymatter (DM) yields are normally attained from sowing early and production ...
Alfalfa coumestrol content in response to development stage, fungi, aphids, and cultivar
(American Society of Agronomy, 2018-03-29)
Coumestrol produced by alfalfa (Medicago sativa L.) can reduce the ovulation rate of ewes. This study isolated agronomic factors that affect coumestrol levels in alfalfa. Fungal diseases explained most differences in ...
