Varieties

Hills

White Icicle, Scarlet globe, Rapid Red White Tipped

Plains

Co 1, Pusa Rashmi, Pusa Chetki, Pusa Desi, Japanese White and Arka Nishant are popular varieties.

Soil

Sandy loam soils with high organic matter content are highly suited for radish cultivation. The highest yield can be obtained at a soil pH of 5.5 to 6.8. Roots of best size, flavour and texture are developed at about 15°C.

Season of sowing 
June –July in hills and September in plains are best suied.

Seed rate 
About 10 kg/ha seeds are required.

Preparation of field 
The land should be prepared to fine tilth and levelled.

Spacing 
15 x 10 cm spacing is normally adopted.

Irrigation
Plains 
Irrigation is done once in a week

Drip irrigation 
Install the drip system with main and sub-main pipes and place the inline lateral tubes at an interval of 1.5. Place the dripper in lateral tubes at an interval of 60cm and 50cm spacing with 4LPH and 3.5 LPH capacities respectively. Form the raised beds at 120 cm width at an interval of 30cm and place the laterals at the centre of each bed.

Application of fertilizers
Plains 
Apply FYM at 25 t/ha and 25 kg N, 100 kg P and 50 kg K/ha as basal dressing and 25 kg N/ha after 30 days.

Fertigation
Fertigation requirement :50:100:50kg of NPK / ha. Apply once in three days 
Spacing : 30x15x10 cm in paired row system. A total of 10 rows is accommodated in one bed.

Fertigation schedule 
Recommended Dose: 50:100:50 kg/ha                     100% of TRD: 50: 25: 50 NPK kg/ha

2. 13:0:45 = 50 kg / ha 
3. Urea = 50 kg / ha

After cultivation 
Weeding and hoeing can be done as and when necessary. At the second weeding, thinning of densely sown plants should be done.

Plant protection
Pests

Aphids, flea beetles and mustard saw fly 
Aphids, flea beetles and mustard saw fly can be controlled by spraying Malathion 50 EC 1 ml/lit twice or thrice at 10 days intervals.

Diseases
White rust 

White rust can be controlled by spraying Mancozeb 2 g/lit or Copper oxychloride 2 g/lit.

Yield
About 20 – 30 t/ha in 45 – 60 days can be obtained.
