PRODUCTION TECHNOLOGY OF RADISH

  1. INTRODUCTION:

  2. Botanical name: Raphanus sativus

  • Family: brassicaceae

  • Chromosome no: 2n=18

  • Origin: radish is originated in Europe and Asia

  1. CLIMATE

  • Ideal temperature for growth and development of quality roots in radish is 10-15.5*C

  • Though it can tolerate high temperature.

  • Roots develop pungency under hot weather.

  • Hence, it should be harvested when roots are small and tender during hot periods.

  1. LAND PREPARATION AND SOWING

  • As the radish is the root crop, it requires loose and friable soil, rich in organic matter.

  • Land should be ploughed up to fine tilth.

  • Make ridges at height of 25 cm height and at a distance of 30-45 cm distance.

  • Add 20-25 tons farm yard manure at the time of field preparation.

  1. SOWING OF SEED

  • Place the seeds on the ridges, at a distance of 6-8 cm.


  • The seed rate should be 10-12kg/ha.

  • The seeds should be sow at a depth of 1.5-3.0cm.

  1. IRRIGATION TO THE FIELD

  • Radish require plenty of water from sowing to harvesting.

  • Apply water after seed sowing.

  • If the irrigation is not sufficient, then the roots get pungent and hard to consume.

  1. INTERCULTURAL OPERATIONS

  • Earthing up: making the soil upward to above the roots to avoid sun scarching.

  • Weeding: removal of weeds in the field to avoid the competition.

  • Mulching should be done to avoid growth of weeds.

    7.HARVESTING:
  • The roots are ready for harvest in 22-55 days after sowing.

  • If harvesting is delayed, the roots became bitter and pithy.

  • Harvesting is done manually. better to give lite irrigation before harvesting, for good uprooting(harvesting).

   8.YIELD:
  • Indian varieties give 15-20ton/ha, Europian varieties give 5-7tons/ha.

  • The radish can be stored for 2-3 days under room temperature without imparting quality.

  • Roots can be stored for about 2 months at 0*C and 90-95% relative humidity.

Plant protection Pests Mango hopper (Tenemanchu purugu) ( Idioscopus clypealis , Idioscopus nitidulus   Amritodus atkinsoni   )             Damage is caused by sucking sap from tender leaves and inflorescence. Ovipositional punctures also cause damage to tender leaves and inflorescence. Severely infested leaves become curled and inflorescence gets dried. Affected parts are covered with honeydew and sooty mould. Control One spray with carbaryl @ 3 gms/litre of water in November before panicle  formation   ensuring  that tree trunks are also thoroughly drenched during the spray. During full length stage of panicle but before full bloom full bloom stage spraying with endosulfan @ 2 ml /litre of water or Dimethoate @ 2 ml /litre of water or imida cloprid @ 0.3 ml/ litre of water if incidence of hoppers is high (more than 5-10 per panicle).After fruit set at pea size stage spraying with imida c...
