SUGGESTED SOWING DENSITY: Density depends on the size requirement of the bulbs and the target market/uses of the final product, however we suggest:
Final population of 750 000 – 950 000 plants per hectare
SEED REQUIREMENT PER HECTARE:
Direct sowing: 900 000 to 1 200 000 seeds per hectare / 3.5 – 4.0 kg seed per hectare
