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 ...
Impact of autumn (fall) dormancy rating on growth and development of seedling lucerne
(Journal of New Zealand Grasslands, 2016)
To quantify the influence of autumn (fall) dormancy (FD) on DM production and phenological development during the seedling phase, three lucerne genotypes with contrasting ratings were grown at Lincoln University, New ...
(Food and Agriculture Organisation of the United Nations, 2012)
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 ...
Soil water extraction patterns of lucerne grown on stony soils
(Springer-Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05)
Background and aims: Lucerne (Medicago sativa L.) is often grown under water-limited production conditions due to its capacity to extract water from deep soil layers through an extensive taproot system. These soils often ...
Yield and quality changes in lucerne of different fall dormancy ratings under three defoliation regimes
(Elsevier B.V., 2020-04-01)
This study determined how fall dormancy rating (FD2, FD5 or FD10) of lucerne genotypes affected crop yield and quality. One field experiment was measured for three growing seasons as a seedling crop and then three defoliation ...
Development, growth and water extraction of seeding lucerne grown on two contrasting soil types
Dryland lucerne (Medicago sativa L.) was established at Lincoln University, New Zealand in two soils which differed in the plant available water content (PAWC). The high PAWC site is a silt loam soil with ~325 mm of water ...
Sowing date affected shoot and root biomass accumulation of lucerne during establishment and subsequent regrowth season
(Elsevier on behalf of the European Society for Agronomy, 2015-08)
© 2015 Elsevier B.V. The pattern of perennial dry matter (DM) was manipulated over two seasons to determine if the establishment of lucerne (Medicago sativa L.) is regulated by the demand for assimilate by perennial organs, ...
Growth and root : Shoot dry matter partitioning in seedling lucerne
Sowing date affected shoot and root biomass yield in seedling lucerne. Biomass partitioning to roots was influenced by photoperiod and water stress.
Deconstructing agronomic resource use efficiencies to increase food production
(PAGEPress on behalf of the Italian Society for Agronomy, 2021-03-22)
Food production per unit land area needs to be increased, thus cropping systems need to use nutrients, water and solar radiation at as close to maximal efficiencies as possible. We deconstruct these efficiencies into their ...
