Silphia seeds(Silphium Perfoliatum<\/i>) – 3kg bag for 1 Hectare<\/h1>\n

Transform your crop rotation over the long term with “Plante Coupe”: a sustainable, profitable and ecological crop.<\/b><\/p>\n

The 3kg<\/b> bag of Agribiomix certified seed<\/b> is sized to plant 1 hectare<\/b> of Silphia. Once installed, this perennial crop produces biomass for more than 15 years<\/b> without further sowing or tillage. <\/p>\n

Why plant Silphia on your farm?<\/h3>\n

Silphie is the Swiss Army knife of agricultural diversification. It meets three major profitability objectives: <\/p>\n

    \n
  • \n

    \u2705 High-performance methanization:<\/b> With a methanogenic power close to that of corn (approx. 260 to 300 m\u00b3 CH4\/t MS), Silphie produces between 14 and 20 tonnes of Dry Matter\/ha from the 2nd year.<\/p>\n<\/li>\n

  • \n

    \u2705 Protein forage:<\/b> Ideal for heifers and suckling cattle (rich in protein, calcium and potassium), it secures your forage stock against drought thanks to its deep rooting.<\/p>\n<\/li>\n

  • \n

    \u2705 Exceptional honey yield: A<\/b> real pollinator magnet, the yellow summer bloom (July-September) means honey production of up to 150 kg\/hectare<\/b>.<\/p>\n<\/li>\n<\/ul>\n

      \ud83d\udca1 Agribiomix Expert Advice:<\/b> 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. <\/p>\n<\/blockquote>\n
