Land Preparation

To prepared fine seed bed, give two to three ploughings in medium soil. For heavy soils, take ploughing for three to four times. Carry out planking after each ploughing to obtained uniform bed.

Sowing

Time of sowing:
As it is long duration crop, complete sowing in second fortnight of October. By planting method, the crop is sown in the month of June-July and harvesting is done in the month of August-September. To obtain good yield avoid delay in sowing.

Spacing:
Under rainfed condition, use spacing of 45 cm between two rows and 10 cm between two crops.

Sowing Depth:

Sow seeds at depth of 3-4 cm.

Method of sowing:

Fennel can be directly sown where as in some areas it first raised in nursery then transplanted to main field.
 

Seed

Seed Rate:
For sowing use seed rate of 3-4 kg per acre.

Seed treatment:
Use Bavistin medicine @2 gm/kg of seed rate and then do the sowing.

Apply well decomposed cowdung@4-6 qtl/acre in soil at time of land preparation. Apply Nitrogen@35kg/acre in form of Urea@15 kg/acre in two to three equal splits. First nitrogen application is as basal dose, apply remaining dose of Nitrogen 30 and 60 days after sowing. Use of phosphorus fertilizer is based upon soil test results; apply it if its deficiency is observed.

 

Irrigation

For better germination of seeds, apply pre-sowing irrigation. First irrigation is given 7-8 days after sowing. Depending upon soil type and climate, apply remaining irrigation at interval of 20-25 days. Avoid water stress at flowering and seed formation stage.

Weed Control

Depending upon weed intensity, carry out, one or two hoeing operation. To control weed chemical, apply Pendimethalin@1 ltr/acre. First weeding is done after 30 days of sowing, second and third is done when necessary.

Plant protection

Aphids
  • Pest and their control:

Aphid: If infestation of Aphid is observed, to controlled take spray of Dimethoate 30EC@2ml per litter of water or Methyl demeton 25EC@2ml per liter of water.

Powdery Mildew
  • Disease and their control:

Powdery Mildew: If infestation is observed, take spray of wettable Sulphur@2gm/ltr of water.

Harvesting

Depending upon variety used, crop is ready to harvest in 180 days, i.e. end of April or end of May. It gives an average yield of 8-12 qtl/acre.
