Post harvesting

Given below is the sequence of harvesting:

January:

  • Harvest designated areas where late planting has been done
  • Mark plants separately for seed purpose

Storage of seed rhizomes

  • Soak seed rhizomes in 0.3% dithane M45 and 0.1% malathion solution for 30 minutes
  • Drain and dry in shade
  • Store in pits under shade; alternate with layers of sand / saw dust
  • Cover with wooden / earthen lid

Post harvest

  • Cure finger and mother rhizomes separately
  • Cure through boiling in fresh water
  • Dry under sun by spreading 5-7 cm thick bamboo mats
  • Dry for 10-15 days
  • Polish using mechanical dryer

February

  • Inspect seed rhizomes once in 20 days
  • Monitor onset of diseases

April

  • Prepare main field after summer showers
  • Plough fields into fine tilth and form 1 m beds of 25 cm height
  • Provide proper drainage channels
  • Apply 40 tonnes of well powdered farm yard manure, 185 kg super phosphate, 50 kg muriate of potash / hectare as basal dose
  • Plant turmeric in the second fortnight with rhizomes of 20-25 gm weight
  • Plant at required distances
  • Mulch hole bed with 15 tonnes green leaves / hectare

May

  • Weed as necessary
  • Top dress with 65 kg urea after 40 days
  • Earth up beds
  • Repeat mulching of beds with green leaves / weeded material @ 5 tonnes

June and July

  • Remove weeds by hand weeding
  • Clear drainage
  • Apply second round of manure
  • Spray 0.05% dimethoane (167ml/100l) to control shoot borer
  • Uproot clumps in case infestation begins
  • Control disease spread as suggested

August

  • Weed and earth up as necessary
  • Avoid water stagnation by proper drainage
  • Watch for rhizome rot and control as suggested

September

  • Weed and earth up as necessary
  • Avoid water stagnation by proper drainage
  • Spray trichoderma @ 0.5 kg / plant at the root zone and spray pseudomonas (0.2%) on foliage to arrest fungal onslaught

October

  • Weed and earth up as necessary
  • Avoid water stagnation by proper drainage
  • Drench soil in 0.3% dithane M45 or 0.3% chestnut compound to prevent rhizome rot
  • 1% Bordeaux mixture or 0.2% dithane M 45 (200g/100l of water) can be sprayed if leaf spot is noticed
  • 0.05% Monocrotophos (140ml/100 l water) can be used to control the incidence of shoot borer

November

  • This is the time to select disease free plants for collecting seed turmeric
  • Weeding, earthing of beds and mulching can be done, if required
  • Drainage canals must be in place, to avoid stagnation
  • Drench soil in 0.3% dithane M45 or 0.3% chestnut compound to prevent rhizome rot
  • 1% Bordeaux mixture or 0.2% dithane M 45 (200g/100l of water) can be sprayed if leaf spot is noticed

December

The month of December is usually split into the harvest, storage and post harvest management sessions.

Harvesting

  • Harvesting may be done in areas where late planting was done
  • The seed turmeric plants must be marked separately and be used for seed purpose
  • The remaining plants can be harvested on maturity

Storage

  • Seed rhizomes can be soaked in 0.3% dithane M45 and 0.1% malathion solution for 30 minutes
  • They must be then drained and dried in the shade
  • Seed rhizomes must be stored in pits under the shade with alternate layers of saw dust or sand
  • Cover with an earthen or wooden lid with holes or with coconut fronds

Post Harvest

  • Fingers and mother rhizomes must be cured separated for better graded produce
  • Curing can be done by boiling rhizomes separately in fresh water and drying in the sun
  • Sun dry rhizomes in 5-7 cm thick layers on clean bamboo mats
  • Polish dry turmeric using mechanical polishers
