Hills: In hilly areas at elevation above 1500 metres, under assured irrigation carrot can be grown throughout the year but at elevations between 1000 - 1500 metres, Carrot can be grown between July - February.

Plains: In plains carrot is grown in the month of August.

Seed rate

Seed rate is : 4 kg/ha

Spacing

Rows are marked with spacing of 25 - 30 cm apart. Sow the seeds mixed with sand and it should be one part of seed with 4 parts of sand.

Thinning

Hills: Between plants it should be 10cm

Plains: Between plants it should be 5cm

Preparation of field

Hills: The field should be prepared to a fine tilth and form raised beds of 15 cm height, one metre breadth and convenient length.

Plains: Two ploughings are given and ridges and furrows are made at 30 cm spacing.

Carrot Seed treatment

Seed treatment with 5% Trichoderma viride.

Before transplanting, seedling root dip with 5% Pseudomonas fluorescens.

• Sprinkling horn manure to the soil at the time of land preparation at 75g/ha by dissolving it in 40 litres of water.

• Application of well decomposed farm yard manure at 50 t/ha at the time of land preparation.

• Application of biodynamic compost at 5 t/ha at the time of land preparation.

• Application of vermicompost at 5 t/ha at the time of land preparation.

• Application of neem cake at 1250 kg/ha at the time of land preparation.

• Application of biofertilizers, Azospirillum and Phosphobacteria at 25 kg each/ha at the time of land preparation.

• Spraying cow pat pit at 5 kg/ha in 100 litres of water on 45th, 60th and 75th day after planting.

Weeding

First weeding should be done on 15th day. Thinning and earthing up is to be given on 30th day.

Growth regulators

• Foliar spraying of panchagavya at 3 per cent at 10 days interval from 1st month after sowing.

• Spraying 10% vermiwash 5 times at 15 days interval from one month after sowing.

• Foliar spray of horn silica at 2.5 g/ha in 50 litres of water on 65th day after sowing to increase the yield and quality of the carrot roots.
