• Plough or dig the land to a depth of 15-20 cm.
• Prepare mounds at a spacing of 90 cm x 90 cm
• Incorporating cattle manure @ 1 kg per mound.
• Plant the whole tuber, one in each mound and cover completely with soil.
• Mulch the mounds to maintain optimum temperature and moisture.

Minisett planting technique

• Clean and healthy tubers weighing about 1 kg are cut into cylindrical (disc-like) pieces, each about 5 cm thick.
• From each such piece, 2-4 small pieces (30 g) are obtained by cutting the disc longitudinally or along the two perpendicular diameters. This is called a minisett.
• The minisetts are then spread out under light shade for an hour with cut surface facing up before planting them in the nursery seed beds.
• The minisett takes 2-3 weeks for sprouting.
• At this stage, they are transplanted to the main field at a spacing of 50 cm on ridges taken 1m apart.
