Silphia seeds(Silphium Perfoliatum) – 3 kg bag for 0.75 to 1 hectare
Transform your crop rotation over the long term with “Plante Coupe”: a sustainable, profitable and ecological crop.
The 3kg bag of Agribiomix certified seed plants 0.75 to 1 hectare of Silphia. Once installed, this perennial crop produces biomass for more than 15 years without further sowing or tillage.
Why plant Silphia on your farm?
Silphie is the Swiss Army knife of agricultural diversification. It meets three major profitability objectives:
-
✅ High-performance methanization: With a methanogenic power close to that of corn (approx. 260 to 300 m³ CH4/t MS), Silphie produces between 7 and 16 tonnes of dry matter/ha per year once established (3rd year).
-
✅ Protein forage: Ideal for heifers and suckling cattle (rich in protein, calcium and potassium), it secures your forage stock against drought thanks to its deep rooting.
-
✅ Late-summer forage for bees: A real pollinator magnet, the yellow summer bloom (July-September) feeds bees and pollinators in late summer, when flowers are scarce.

💡 Agribiomix Expert Advice: Planting is the critical stage. To secure your first-year emergence, we recommend precision pneumatic seeding (35-40 cm row spacing) and a very fine seedbed. Silphia establishes its root system in the first year and explodes in biomass in year 2.
