This patchy growth of barrel medic has been linked to variability of soil acidity (Little et al.
A pasture species commonly grown in these farming systems, barrel medic (Medicago truncatula), may be expected to have increased yield in soil of the burn zones at sites in this experiment, as it prefers to grow in neutral to alkaline soil (Schipp and Young 2004).
Silver, Sava, and Essex), and barrel medic
(Medicago truncatula cv.
is both a forage crop and a model legume.
Funded by a 4-year National Science Foundation grant, the barrel medic
genome project includes collaborators at the Universities of California-Davis and Minnesota and with the Noble Foundation.
Studies in Australia with burr medic (Medicago polymorpha) and barrel medic
(Medicago truncatula) showed that only 25% of hard seed had softened in the first summer when left on the soil surface; 40% to 50% hard seed remained after two summers (Taylor and Ewing).
Replicated plots were planted to compare with 'Jemalong' and 'Parabinga' barrel medic
In summary the design was: main-plot factor, 3 harvests [27 and 48 days after planting, and at maturity (91 days)]; subplot factors, 4 residues [non-residue control, Flemingia leaf, barrel medic
hay, and wheat straw] x 2 fertilisers [N, NPKS] x 3 replicates.
2000) showed the following overall ranking of species, on the basis of freezing resistance: Hairy vetch (best), yellow sweetclover, crimson clover, black medic, subclover, barrel medic
, and snail medic (poorest).
Since other legumes may have better potential as overwintering cover crops, the freezing resistance was also studied in the following species: Crimson clover, black medic, barrel medic
, snail medic, yellow sweetclover, and hairy vetch.
Alston and Puckridge (1986) found that the initial growth of barrel medic
