Pre sowing seed management

  • Coat the seeds with TNAU Vidhai Amirtham @ 68 ml/ kg of seeds.
  • TNAU seed pelleting technology may be used to increase the seed size and weight to facilitate precision sowing using seed drill.

Method of sowing

  • Form ridges and furrows and apply recommended dose of fertilizer along the furrows.
  • Mix the seeds with four times of its volume of dry sand and drop the mixture evenly along the furrowsand cover with soil.

Unpelleted seed

Pelleted seed


Fertilizer
  • Apply NPK @ 50:25:25 kg / ha and Manganese sulphate @ 5 kg / ha as basal
    application

Foliar application

  • Spray 1 % DAP at the time of first flowering and 10 days after the first spray for enhanced seed set

Fertilizer application

Roguing
  • Roguing should be done from vegetative to reproductive stage, based on plant,leaf,flower, pod and seed characters.
  • In addition to the offtypes, the pest and disease affected plants should also be removed.
Field Inspection
  • A minimum of three inspections shall be made, i) before flowering, ii) during flowering iii) prior to harvesting.

Harvesting

  • Harvest the crop when 75 - 80 % of the pods started yellowing and bottom 1 or 2
    pods have dehisced. At this stage, the pod moisture content will be 50 - 60 % and
    seed moisture content will be 25 - 30 % and the seeds will be chocolate brown colour.
  • Stake the plants in inverted position and cure them for 3 - 4 days.
Threshing
  • Beat the staked plants with pliable bamboo stick for removal of seeds.
Drying
  • Dry the seeds to 7- 8 % moisture content.

Seed grading

  • Grade the seeds with 4 / 64” round perforated sieve.

Pre-storage seed treatment


  • Treat the seeds with carbendazim @ 2 g / kg along with carbaryl 200 mg / kg of seed.

Storage

  • Store the seeds with a seed moisture content of 8 - 9 %.in gunny or cloth bag for short term storage (8 - 9 months).
  • Store the seeds with a seed moisture content of 6 - 7 %.in polylined gunny bag for medium term storage (12 - 15 months).
  • Store the seeds with seed moisture content of 5 %.in 700 gauge polythene bag for long term storage (more than 15months).
