Seed rate: 1500 - 1800 kg of rhizome/ha.

Spacing: For irrigated crop, ridges are formed 40 cm apart and rhizomes planted at 20 cm spacing.

Manures and Manuring
Basal: FYM 40 t, 50 kg P and 25 kg K/ha.
Top dressing: 37.5 kg N and 12.5 kg K/ha each applied on 45th and 90th day.

Plant protection against Pests
Shoot borer: Spray dimethoate 30 EC 2 ml/lit or phosphamidon 40 SL 2 ml/lit.
Leaf roller: Spray carbaryl 50 WP 2 g/ha or quinalphos 25 EC 2 ml/lit.

Plant protection against Diseases
Soft rot (Pythium sp.): Lack of drainage and continued dampness expose the plants to infection.
The disease spreads through the seed rhizomes and soil. Provide adequate drainage facilities and select healthy and disease-free seed rhizomes and pre-treat the seed rhizomes. In the field drench the bed with 2.5 g/lit of Copper oxychloride or 1% Bordeaux mixture or Metalaxyl mancozeb 4 g/lit. Treat the seed rhizomes with Mancozeb or Copper oxychloride 3 g/lit or 200ppm Streptocycline for 30 minutes before storage.
Leaf spot: Spray with 1 % Bordeaux mixture or Copper oxychloride 0.25%.

Harvest: The crop can be harvested after 8 - 9 months when leaves start yellowing and drying.
