  • 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.

  • 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.
