		Organic cultivation of Carrot Varieties Hills: Ooty-1, Early Nantes and New Koroda Plains: India Gold, Pusa Kesar and Half Long Danvers Soil Carrot is a cool season crop and when grown at 15°C to 20°C will develop a good colour. The carrot crop needs deep loose loamy soil. It requires a pH ranging from 6.0 to 7.0 for higher production. Season Hills: At elevation above 1500 metres, Carrot can be grown throughout the year under assured irrigation. At elevations between 1000 - 1500 metres, Carrot can be grown in July - February. Plains: August. Seed rate 4 kg/ha Spacing Mark the rows with spacing of 25 - 30 cm apart. Sow the seeds mixed with sand (one part of seed with 4 parts of sand). Thinning Hills: 10 cm between plants Plains: 5 cm between plants Preparation of field Hills: Prepare the land 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 formed at 30 cm spacing. Seed treatment Seed treatment with cow pat pit @ 3 g in 1 litre of water for 24 hours Seed treatment with 5% Trichoderma viride Seedling root dip with 5% Pseudomonas fluorescens before transplanting Irrigation Irrigation should be given once in five days. During drought period, after giving irrigation in the evening, beds should be covered with wet gunny bags. This prevent excessive water loss during sunny days. Germination of the seeds is also improved. Application of fertilizers Green manuring with lupin 60 days before planting Sprinkling horn manure to the soil at the time of land preparation @ 75g/ha by dissolving it in 40 litres of water Application of well decomposed farm yard manure @ 50 t/ha at the time of land preparation Application of biodynamic compost @ 5 t/ha at the time of land preparation Application of vermicompost @ 5 t/ha at the time of land preparation Application of neem cake @ 1250 kg/ha at the time of land preparation Application of biofertilizers, Azospirillum and Phosphobacteria @ 25 kg each/ha at the time of land preparation Spraying cow pat pit @ 5 kg/ha in 100 litres of water on 45th, 60th and 75th day after planting After cultivation First weeding is to be done on 15th day. Thinning and earthing up should be given on 30th day. Growth regulators Foliar spraying of panchagavya @ 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 @ 2.5 g/ha in 50 litres of water on 65th day after sowing to increase the yield and quality of the carrot roots Plant protection Pests Carrot is not much affected by pests. Root knot nematode Application of neem cake @ 1 ton/haat the time of sowing to control root knot nematode, Meloidogyne spp Growing carrot once in 3 years by following crop rotation Growing marigold once in 2 years Aplication of Paecilomyces lilacinus @ 10 kg/ha before sowing seeds Diseases Leaf spot Foliar spray of 5% Manchurian tea filtrates 3 times at one month interval from one month after sowing/planting. Foliar spray of 3% Dasagavya at 10 days interval from 1st month after planting. Soil borne diseases Application of Trichoderma viride @ 5 kg/ha at the time of land preparation. Application of Pseudomonas fluorescens @ 5 kg/ha at the time of land preparation. Yield 25 - 30 t/ha in 100 - 120 days.
