Soaking — 12 hours
6-12 hours soaking after scarification; seeds absorb water 24-48 hours after planting if moisture available

🔨
Mechanical scarification
45-73% of seeds are hard and require scarification; mechanical scarification with sandpaper is effective; chemical (sulfuric acid) scarification not effective for M. sativa

Additional notes
Mechanical scarification by nicking or scratching seed coat improves water absorption; soaking 6-12 hours after scarification
Substrate & Container
Recommended substrate
well-draining seed-starting mix, loamy soils
Recommended container
containers or prepared seedbeds
Growing Tips
Maintain consistent moisture during germination; seeds will not germinate below 0-2°C or above 40°C; germination accelerated at 20-25°C; seeds show genetic diversity in germination response to temperature; store seed at cool temperatures and low humidity; inoculate with Rhizobium bacteria for nitrogen fixation; broadcast seeding may enhance germination in certain soil types
