How does defoliation management impact on yield, canopy forming processes and light interception of lucerne (Medicago sativa L.) crops?
The frequency of defoliation is the major management tool that modulates shoot yield and the accumulation of C and N root reserves in lucerne crops. A fully irrigated, two year old lucerne (Medicago sativa L.) crop was ...
Defoliation frequency and season affected radiation use efficiency and dry matter partitioning to roots of lucerne (Medicago sativa L.) crops
Radiation use efficiency (RUE), and subsequent partitioning between shoots and roots were investigated for ‘Grasslands Kaituna’ lucerne crops grown in the cool temperate climate of Canterbury, New Zealand. Crops were ...
Growth and phenological development patterns differ between seedling and regrowth lucerne crops (Medicago sativa L.)
This study compared physiological responses of fully irrigated seedling and regrowth lucerne crops (Medicago sativa L.) grown under similar environmental field conditions. Measurements occurred for 2-4 years after sowing ...
Relationships between dry matter yield and height of rotationally grazed dryland lucerne
(New Zealand Grassland Association, 2016)
Between 2009/2010 and 2014/2015 a total of 711 destructive paired samples of total dry matter yield (kg DM/ha) and lucerne height were taken from a grazed dryland lucerne monoculture experiment at Ashley Dene, Canterbury, ...
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 ...
