Carrot crop required well decomposed cowdung@20-30ton/acre, along with this fertilizer dose of Nitrogen@20 kg (in form of Urea@45 kg), Phosphorus@16 kg (in form of SSP@ 100 kg/acre) and Potash@18 kg (in form of MOP@30 kg) per acre.Â
Â
Full dose of Cow dung, Phosphorus, Potash and half dose of Nitrogen is applied at the time of land preparation. Remaining half dose is applied 45 to 50 days after sowing.Â
Â
Take intercultural operation like weeding and hoeing to keep check on weed growth also to provide soil aeration. Weed control is necessary during early stage. After sowing, take spray of Pendimethalin@ 1Ltr per acre. At time of weedicide application, sufficient moisture should present in soil.Â
After sowing, apply first irrigation, it will help in good germination. Depending upon soil type and climate, apply remaining irrigations at interval of 6-7days in summer and 10-12 days interval in winter month. Overall carrot required three to four irrigations. Avoid excessive irrigation as it will leads misshape of roots and numerous hair growth. Stop irrigation two to three weeks before harvesting, It will help in increase in sweetness and taste of carrot.
PLANT PROTECTION  
Nematodes:
Nematodes:Â To control nematodes, apply neem cake@0.5ton/acre at time of sowing.
Â
Leaf Eating Caterpillar:
Leaf Eating Caterpillar: They feed on leaves. If infestation is observed in field to control of leaf eating caterpillars take spray of Dichlorvos@200ml/150Ltr water or Flubendiamide 48%S.C@0.5ml/3Ltr of water.
Leaf spot:Â
Leaf spot:Â If infestation is observed in field to control take spray of Mancozeb@2gm/Liter of water.
HARVESTING
Depending upon variety, carrots are ready for harvesting in 90-100days after sowing. Harvesting is done manually by uprooting plants. After harvesting remove green tops from carrots and then they are washed with water. It gives an average yield of 83-105qtl/acre. Â
