Growing Tips
Use stem cuttings 20-30 cm long from the middle portion of mature stems — these have the highest starch reserves and sprout most reliably.
Plant cuttings at a 45-degree angle with two-thirds buried in the soil for optimal root establishment and wind resistance.
Cassava is extremely sensitive to waterlogging — avoid low-lying fields prone to flooding, as root rot develops within days of saturation.
Harvest bitter cassava varieties within 48 hours of uprooting, as cyanogenic glucosides increase post-harvest, making roots toxic if not processed promptly.
Intercrop with legumes (cowpea, groundnut) during the first 3 months — cassava canopy is sparse early, and legumes fix nitrogen for the next cycle.
Apply potassium-rich fertilizer (muriate of potash) at 3-4 months after planting — cassava extracts up to 150 kg K₂O/ha and depletes soil potassium rapidly.
