12. Medicinal value Add a Footer 12 The ancient Greek physician Galen (prominent among the Romans) mentioned asparagus as a beneficial herb during the second century. T he Indian Ananga Ranga attributes to "special phosphorus elements" that also counteract fatigue. Help to fought against cancer . (Glutathione ) Packed with Antioxidants.

14. TYPES OF ASPARAGUS There are mainly four types of Asparagus : Green Asparagus Purple Asparagus White Asparagus Wild Asparagus Add a Footer 14

15. green asparagus This is the main cultivated type of asparagus. About 60% of asparagus is green asparagus . The stems are use for vegetables. Add a Footer 15

16. purple asparagus Purple asparagus is a similar in appearance. Higher sugar content than other asparagus varieties. Purple asparagus colour comes from the high levels of anthocyanins in the spears. Add a Footer 16

17. White asparagus White asparagus is simply green asparagus that has never seen the light of day . Medicinal value is very high . The plant is grown under soil or some other covering to block out the sun's rays. Add a Footer 17

18. Wild asparagus This is a type of asparagus which grown naturally . Mainly grown in the wild area. They are mainly toxic & sub-toxic. Add a Footer 18

19. Cultural practices SOIL TEMPERATURE CLIMATE PROPAGATION NURSERY SEED RATE PLANTING FERTILIZER IRRIGATION WEED CONTROL Add a Footer 19

20. SOIL TEMPERATURE CLIMATE Add a Footer 20 Soil : Loamy sandy soil Well drained and fertile soil pH = 6.0 - 7.5 climate : Production well in mild to cold climates . Asparagus can be grown in a wide range of soils and under various climatic conditions . moist climatic conditions . Climate withstands frost . Needs full sunlight for growth (long day plant). temperature : A cool season crop For Favoring productivity the optimum temperature is 24°C - 30°C (In day ) 13°C - 19°C (In night) .

21. PROPAGATION SEED RATE NURSERY Add a Footer 21 PROPAGATION : From seeds and crowns Nursery raising : Asparagus is raised through seed as well as crowns . Time for raising nursery bed ; Seed rate : 600 gm. /ha to raise the nursery . Mid hills High hills March - June April - May

22. PLANTING Add a Footer 22 Time of planting : Planting distance / Spacing : Spacing should be 150 cm. × 45 cm. Crown is planted in furrows . The width of furrows are 30 cm. and deep of furrows are 25 cm . Depth of planting : 20 – 30 cm. approx. Density of plants 30000/ha . Mid hills High hills January March - April

23. FERTILIZER recommendation Half of FYM + Half of NPK apply in spring season . Nitrogen should be applied in 3 – 4 split doses during planting and harvesting . After harvesting , every year about 20 – 30 kg/ha Nitrogen are applied for better growth . Remaining half of the fertilizers should be applied after cutting of spears . Add a Footer 23 FYM (tonnes/ha) N (kg/ha) P 2 O 5 (kg/ha) K 2 O (kg/ha) 30 - 40 120 100 80

24. IRRIGATION WEED CONTROL Add a Footer 24 IRRIGATION: Well drained (open furrows) beds . Water logging would be harmful . Irrigating asparagus with 25 mm water per week during the fern growing stage . WEED CONTROL : Most of the grassy and perennial weeds in H .P. are controlled by the use of paraquat @ 2-3 kg /ha before emergence of spears . 2,4-D @2 kg /ha after harvesting of spearsand . Glyphosate @ 2-3 kg /ha before emergence of spears and again at the end of harvesting .

25. INSECT Main insects are Asparagus beetles Aphids Plant bugs Alfalfa plant bugs Asparagus miner Add a Footer 25

26. CONTROL OF ASPARAGUS BEETLES CONTROLLED THROUGH : Maintenance Of Clean Bed . Elimination of over-water debris and any wild asparagus near the production area . Use pf insecticides like malathion @ 0.05% . Add a Footer 26

27. CONTROL OF Aphids CONTROLLED THROUGH : Maintenance of clean bed during the cutting . Disyston is effective as a control for asparagus aphid . Use pf insecticides like malathion @ 0.05% ,triazophos @ 0.15% . Add a Footer 27

28. DISEASES The major diseases are Rust Fusarium crown Spear Rot Blight Virus Add a Footer 28

29. CONTROL OF Rust CONTROLLED THROUGH : Tolerant Cultivars . Proper management . Use fungicides like zineb after harvest . Clean cutting and burning old canes each year . Add a Footer 29

30. CONTROL OF Fusarium crown CONTROLLED THROUGH : Tolerant (vigorus)Cultivars . Treat the seeds with sterilized medium . Use fungicides . Avoid stress (drought , poor drainage , poor fertility etc.) . Add a Footer 30

31. MANAGEMENT HARVESTING BLANCHING YIELD STORAGE Add a Footer 31

32. blanching Add a Footer 32 Practiced to blanch the young spears . A common practices after harvesting the green asparagus. Hilling is done in case of large scale and here blanching is required . We should do the blanching to detoxify the plant and inactivating the activated enzymes . Asparagus is one of the earliest spring vegetables. Time period of fully matured asparagus minimum three(3) years and maximum seven - eight(7 – 8) years from planting . Normal harvest period for a fully developed asparagus bed is 8 weeks. The spear length should be approx. 20-25 cm on the time of harvesting . Harvested by cutting 3 – 4 cm below the surface soil . HARVESTING

33. yield Add a Footer 33 After 7-8 years of planting a fully developed asparagus fields yield About 40-50 q/ha . Mature asparagus are stored for future . The spears may be held at 0°C - 2°C and 95% RH for no longer than 14 – 18 days . storage
