Elephant foot yam seed-set preparation

Elephant foot yam is propagated by corm pieces (seed sets) of 500-750 g cut from mother corms with at least one healthy bud. ICAR-CTCRI recommends cutting corms 1-2 days before planting, dipping the pieces in cow-dung slurry + Trichoderma viride, shade-drying, and treating with mancozeb (0.3%) or carbendazim against fungal rots.

Key parameters

  • Seed Set Weight: 500-750 g corm pieces with healthy bud
  • Treatment: cow-dung slurry + Trichoderma viride; mancozeb 0.3%
  • Spacing Depth: 90 x 90 cm; 15-20 cm depth
  • Planting Time: April-May; sprouting in 30-40 days

Implementation and adoption

Planted in pits at 90 x 90 cm spacing at 15-20 cm depth in April-May, the treated seed sets sprout in 30-40 days.
