Overview

AGWEST® Bartolo is a semi-prostrate aerial seeded clover that does not shed seed after maturity. Bladder clover is a self-pollinating species and produces small pink flowers. The whole inflorescence may produce up to 150 seeds. Seeds are around 2 mg in size and are yellow in colour and physically very hard.

AGWEST® Bartolo has a midseason maturity, flowering approximately 105 days after emergence from a mid May sowing in Perth.                                

• Suited to regions with 325 to 500 mm annual rainfall.

• Can grow successfully on mildly acid and alkaline sandy-loam, loam and clay soils (pH 5 to 8 CaCl2).

• Seed should be inoculated with Group C inoculants for clovers and is normally sown at 2 to 6 kg/ha in mixes or 10 kg/ha as a straight.                               

Pest and disease tolerance

• Low to moderate sensitivity to red-legged earth mite.

• Moderately tolerant to blue green aphid and lucerne flea.

• Tolerant of native budworm.

• Little or no sensitivity to clover scorch disease. Occasional infections of pseudopeziza leafspot have been observed in high rainfall areas.

• Susceptible to CMV, BYMV and AMV viruses (similar to subterranean clover).                                                        

Field Performance and Management

• High herbage production across a range of soil types.

• Excellent grazing tolerance once established.

• Seed becomes germinable in autumn, offering some protection against false breaks of season.

• AGWEST® Bartolo is hard seeded with over 50% of the seed remaining hard after one summer. It is suited to self-regenerating ley systems or short-term phase farming systems.
