Other claims from this paper (7)

Observation Intensified cropping and in-crop herbicides mitigated seed set from conventional ley legumes.
Intervention effect Dormant summer sowing with G 2 HSLs reduced renovated pasture establishment costs by up to 90 %.
Intervention effect Dormant summer sowing moved pasture renovation to a period with greater labour availability.
Intervention effect DSS of G 2 HSLs increased seed yield 25–50 % relative to conventional sowing of scarified seed.
Observation Post-legume crop yields exceeded 3 tonnes/ha without fertilizer N.
Observation Cereal seed protein levels were maintained or increased.
Method / resource More than 20 G 2 HSL cultivars were commercialised from four genera over five decades.
