Diamanti Bladder Clover

Productive and nutritious with harder seed than Bartolo

In stockDownload tech sheet

Diamanti is a highly productive and nutritious winter legume with greater levels of hard seed than Bartolo providing more resilience to false breaks. It flowers earlier and thus can extend further into the drier regions of the Eastern Wheatbelt.

Key attributes

  • Flowers 10 to 14 days earlier than Bartolo
  • Harder seed is more resilient to false breaks
  • Upright habit makes harvesting easier
  • Hay-type clover with better animal nutrition
  • Out-yields Bartolo by around 35%
  • Diamond leaf marker distinguishes it from Bartolo

About this variety

Diamanti is a bladder clover developed as an improvement on Bartolo, and the comparison with Bartolo is the clearest way to understand it.

It flowers ten to fourteen days earlier, which suits it to shorter seasons or to fitting a legume phase into a tighter rotation. Its seed is harder, making it more resilient to false breaks, where an early germinating rain followed by dry weather would otherwise wipe out a year's seedlings. Its growth habit is upright rather than prostrate, which makes it considerably easier to harvest, an important practical difference for anyone producing their own seed. And across herbage and seed production it out-yields Bartolo by an average of thirty-five per cent.

It is described as a hay-type bladder clover, offering better nutrition to stock than its predecessor, and it is easily told apart in the paddock by its diamond shaped leaf marker, where Bartolo carries a crescent.

Diamanti suits mixed farming rotations on soils from mildly acid to alkaline, where a productive, reliably regenerating annual legume is wanted between crops.

FAQs

What pasture legume will survive in the dry eastern wheatbelt?

We recommend Diamanti Bladder Clover. It flowers earlier than Bartolo, at about 95 days in Perth, so it can extend further into drier eastern wheatbelt areas. It has high levels of hard seed for false-break resilience and a wide pH tolerance of about 5 to 8.

Which legume gives the most feed and seed in low rainfall country like Morawa?

Diamanti Bladder Clover averaged about 35% more herbage and seed than Bartolo in trials, and up to 100% more in the low rainfall zone, including at Morawa. It is highly productive and nutritious and has high nitrogen fixation. Our catalogue lists 250 to 400mm rainfall.

How much Diamanti seed should I sow?

We recommend sowing Diamanti Bladder Clover at 5 to 10 kg/ha, according to our 2026 guide. Inoculate with Group C inoculant. Diamanti can also be dormant summer sown in WA using stored seed, which can save time at seeding.

Can I harvest my own pasture legume seed with a normal header?

Yes, Diamanti Bladder Clover can be readily harvested with a cereal header, as the seed breaks free from the calyx easily. Its upright habit also makes harvesting easier than with Bartolo. Seed yields of 500 to 800 kg/ha are reported, making on-farm seed production practical.

What legume fits a one-year pasture, one-year crop rotation?

Diamanti Bladder Clover is very hard seeded and suits cropping rotations. Once a seedbank is established it is well suited to 1:1 rotations, and it will still regenerate when two crops are occasionally sown between pasture years. In regenerating stands, about 30 to 40% of paddock seed softens each season.

My sub clover struggles on hardsetting soil. What's a better option?

Diamanti Bladder Clover sets seed better than sub clover on hardsetting soils. It suits sands to loams and tolerates a pH range of about 5 to 8. It is a highly productive, nutritious winter legume that holds good feed value during senescence.

Diamanti vs Bartolo bladder clover, which should I sow?

Diamanti flowers 10 to 14 days earlier than Bartolo, has harder seed and an upright, easier-to-harvest habit, and is a hay-type bladder clover. It has outyielded Bartolo in trials. Bartolo suits somewhat higher rainfall and is more prostrate. You can tell them apart by the diamond versus crescent leaf marker.

Is Diamanti clover good feed for sheep?

Yes, Diamanti Bladder Clover is highly nutritious for livestock and keeps high nutritional value during senescence, which helps with summer grazing. A large proportion of seed passes through sheep and stays viable, helping regeneration. As with most legumes, introduce hungry stock gradually.

Is there a pasture legume with better herbicide options than medic?

Diamanti Bladder Clover has broader herbicide tolerance than medic, which gives more flexibility in rotations. It also has high nitrogen fixation, making it a strong break for following crops. Talk to us about specific products before you spray.

Which clover handles both acid and alkaline soils in low rainfall areas?

Diamanti Bladder Clover has a wide pH tolerance of about 5 to 8 (CaCl2), covering mildly acid to alkaline soils on sands and loams. It is early flowering and very hard seeded, so it suits drier cropping country. For more acid sands, Casbah Biserrula is another option we stock.
