varieties
crop Lacy phacelia,
where this is mentioned in the description.
Seed productivity of Phacelia, when optimizing seeding rates to 3 million viable seeds per hectare, reaches 5.8–6.5 dt/ha, whereas traditional indicators are more often 3–4 dt/ha. Key factors for seed yield are the number of branches and inflorescences per plant, which decrease with excessive stand density.
The honey productivity of the crop varies from 100 to 500 kg/ha, reaching up to 1000 kg/ha under favorable conditions, with a single flower capable of producing up to 4–5 mg of nectar. Biomass productivity of Phacelia when grown for green manure purposes can reach 20 t/ha of green mass.
