Seed Production And Hard Seededness Of Trifolium Subterraneum Subsp Brachycalycinum, Michael D A Bolland
Seed Production And Hard Seededness Of Trifolium Subterraneum Subsp Brachycalycinum, Michael D A Bolland
Technical Bulletins
Ungrazed swards of some subsp. brachycalycinum strains produced reasonable seed yields compared with subsp. subterraneum on the sandplain soils and annual Medicago species on the alkaline mallee soils. However, in swards which were grazed by sheep up to the start of flowering, subsp. brachycalycinum produced disappointing seed yields compared with subsp. subterraneum and annual Medicago species. On a sandy soil, prevention of burr burial compared with covering developing burrs with sand drastically reduce ation an inhibiting light factor operates to drastically reduce seed production.

Strains of O. compressus which originate from Paros in southern Greece were the earliest flowering serradellas tested. They consistently produced amongst the highest seed yields, are relatively hard-seeded and are worthy of further investigation for deep sands and very acid soils in low rainfall areas. Monthly applications of nitrogenous fertilizer about doubled the herbage yields of serradella in winter.
