1 Turnip

2 ☻ Turnip is a main cool season crop In Himachal Pradesh. ☻ It is grown as a cash crop during summer months in dry and wet temperate zones and only as a winter crop in the sub-temperate and sub-tropical regions. Botanical Name:Brassica rapa L. Family:Brassicaceae Chromosome number2n=2x=20 Origin:i. Mediterranean (European type) ii. Eastern Afganistan

3 Uses ☻ It is grown for elongated roots as well as for its foliage. ☻ Fresh roots are consumed in salads or cooked as a vegetable or used in pickles. ☻ The turnip greens are rich in vitamin A and C and contain appreciable amount of vitamin B. ☻ A good source of Ca, P and Fe. ☻ The greens are mostly fed to animals and seldom used as green vegetables.

4 Varieties Asiatic/tropical/subtropical type European/Temperate Type More pungent Better for pickles Earlier & more heat tolerant. Sweeter and more palatable. Pusa Kanchan Pusa Sweti Punjab Safed-4 Purple Top White Globe Golden Ball Snow Ball Early Milan Red Top Pusa Chandrima Pusa Swarnima.

5 Varieties recommended for Himachal Pradesh Asiatic typeEuropean Type 1. Pusa Sweti, 2. Pusa Swarnima 1. Purple Top White Globe 2. Snowball 3. Pusa Chandrima 4. Pusa Swarnima Snowball PTWG

6 ♠ A moderately deep, friable, fertile and well drained soil is ideal for turnip. ♠ Extremely clay soils and very sandy soils should be avoided. ♠ Suitable pH for its good growth is Soils

7 Climate ☻ It is best adapted to a cool or moderate climate. ☻ It is a hard crop and can tolerate frost and mildly freezing temperatures. ☻ The roots become woody, tough and bitter in taste in hot weather. ☻ On the other hand, temperature below 10 o C likely to cause flowering. ☻ o C air temperature and o C soil temperature is the most favourable for root development and the ratio of root/green. ☻ Asiatic varieties require warmer conditions are sown earlier than European types.

8 Sowing Time Seed Rate Northern Indian plainsSeptember-December Himachal Pradesh Low HillsSeptember-November Mid HillsAugust – October High HillsApril – July kg/ha

9 Spacing 30-45cm X cm 30 cm X 10cm(H.P.) ◙ Mix the seeds with sand or ash to facilitate uniform sowing ◙ Sowing depth is cm on the ridges. ◙ After germination maintain the distance between the plants with in row by following thinning of plants. Manures and Fertilizers Same as carrot

10 ► Thinning is important to maintain optimum plant to plant spacing and required population. ► Plant should be earthed up days after sowing at the time of top dressing of fertilizers. ► Earthing up is also necessary to get well developed, and quality roots as generally the growing roots tend to push out of the soil. ► Pre-emergence application of following herbicides is very useful for effective weed control Pendimethalin 1.2 kg a.i./ha or Alachlor 1.5 kg a.i./ha or Fluchloralin 0.9 kg a.i./ha or Isoproturan 1.0 kg a.i./ha or 1.0 kg a.i./ha. Interculture and weed control

11 Irrigation ╠A pre-sowing irrigation is to be given to help the seeds absorb moisture and germinate properly. ╠Irrigation frequency and water quantities are depend on the planting season and available soil moisture. ╠The soil should have sufficient moisture to obtain tender and attractive roots. ╠The water requirement would be about 300 mm. ╠In general, the crop is irrigated every days.

12 Harvesting ☻ Turnips should be harvested soon after reaching suitable size, since the quality rapidly deteriorate. ☻ A desirable size is cm in diameter. ☻ Larger roots often cause poor texture and bitter taste. ☻ A light irrigation may be given before harvesting to facilitate lifting. ☻ Harvested roots are cleaned, tops are cut and roots are graded according to size and tenderness Yield q/ha

13 Diseases 1.Powdery mildew 2.Downy mildew 3.Soft rot 4.Dry rot 5.Brown Heart 6.Phyllody: Malformation of flowering shoots affecting the normal fruit set 7.Turnip mosaic virus Insects Aphids, Mustard saw fly, Flea Beetle, Gall Weevil
