• Its origin lies in Persia.
• It is a rich source of carbohydrates, proteins, calcium, phosphorus, iron and vitamin C.
• Pomegranate eaten as fresh fruit also its juice is cool and refreshing.
• Along with juice, each and every part of pomegranate has some medicinal value.
• Its root and peel used to cure diarrhoea, dysentery and worm killing in the intestines.
• Its petals are used for preparing dyes.
• Maharashtra is major producer of Pomegranate. Other states like Rajasthan, Karnataka, Gujarat, Tamil Nadu, Andhra Pradesh, Uttar Pradesh, Punjab and Haryana are also cultivating pomegranate on small scale.

  Other Varieties –

  Jyothi,  Arakta, Rudhra, Solapur Lal and Solapur Anardana

• Bacterial blight tolerant varieties: Nayana, Kalpitiya, 

• Pomegranate is commercially propagated by rooting of cuttings.
• Semi-hardwood  cuttings of one year old are used for rooting.
• The rooting is improved by application IBA 5000  ppm through the quick dip method. (10 to 20 seconds).
• Hardwood cutting of 15 cm length and 6 mm thickness.
• Pre-treat with Carbendazim (0.1%) + Bactronol (2 –Bromo, 2- Nitropropane, 1-3 diol) @ 0.05% for 10 minutes, followed by one washing with tap water and dipping the lower half of the cuttings for 5 minutes in 2000ppm IBA.
• Maintain 85% relative humidity.

It can also be propagated by air layering or gootee, as well as ground layering. Transplanting of rooted cuttings is done during monsoon  season

• Pits of 60 cm x 6o cm x 60 cm size are dug at a spacing of 4 to 5 M between rows and 2  M within the rows, So that higher yield can be obtained during the first 5 years.
• After 5 years, alternate plant within the row can be removed so as to maintain 4 x 4 M or 5x 4 M. Before  planting, each pit should be filled up with 20 kg of FYM and top soil.
• Inoculation of 50 g of  phosphobacterium+ 150 g of Vesicular arbuscular mycorrhiza in the roots at the time of planting  will help better root growth and establishment.  

Pomegranate propagation-

• Air layering is carried out in the month of May/June.
• In this method a 1-2 year old, healthy, vigorous, mature shoot of 45-60 cm in length and pencil thickness is selected.
• A circular strip of bark about 3 cm wide just below a bud is completely removed from the selected shoot
• Rooting hormones like IBA & NAA 50mg each in Lanoline paste are applied over this portion.
• Moist sphagnum moss is packed around this portion and tied with polyethylene sheet to prevent the loss of moisture.
• Application of such hormones promotes early rooting.
• Light brown roots are visible through the polythene wrap in the month of July-August
• The rooted shoot is slowly detached by giving 2-3 successive cuts over a period of week before finally detaching from the parent plant.
• The polythene sheet is removed before planting them in pots.
• They are planted in pots and kept in nurseries under shade.
• Top of the shoot is cut back to maintain a proper ratio of leaves: roots.
• The grafts can be transplanted in the field in the month of September/October

• Plough the land for two – three times and bring soil to fine tilth.
• After then carry out planking operation to make land leveled and uniform.

• Drip irrigation using a pitcher pot or tube will keep the soil moisture constant without  much fluctuation.
• This helps the pomegranate to get better establishment in the early stage as  well as regular bearing in the fruiting phase. 
• In summer apply water at the interval of 10-15 days and in winter increase irrigation interval upto 20-25 days.

• To control weeds, mulching can be done.
• Along with weed control, it helps to conserved moisture and reduces evaporation loss.

24 – 30 months.

NAA 10 mg/l as foliar spray during September when new flush initiation occurs

Training and Pruning help in growth of fresh healthy shoots. It removes old also disease branches and avoids overcrowding of branches. It also maintains proper shape of plant.

• Pomegranate is trained as a bush.
• Pomegranate tree has a tendency to throw out a lot of  suckers. If it is trained on a single stem system and if it is damaged by stem borer then the tree  will be lost.
• Therefore, 3-4 stems are allowed per plant and they are pinched at a height of 1 metre and below the pinched tip of each stem upto 25-30 cm, 2-3 branches well distributed in all  direction are encouraged.
• Such a training will help for good maintenance of the tree.

In pomegranate the fruits are borne terminally on short spurs produced all along the slow  growing mature wood.

• They bear fruit for 3-4 years. Every year during winter a light pruning is  to be given to shorten the previous season growth so as to encourage fruiting.
• Besides this, dead  and diseased branches, water sprouts (suckers) should be removed periodically.
• Water sprouts  from the base should be nipped at the start of their growth so as to avoid wastage of food material in such growth which exhaust the maximum reserve food.
• If such diversion of food is allowed  then there will be very poor bearing in the trees. 

•  Thinning of flower clusters ensures better size of the fruit.
• Spraying liquid paraffin at 1%concentration at 15days interval twice during June reduces fruit cracking.

Pomegranate flowers continuously when watered regularly.

The plants under such conditions may continue bearing flowers and bear small crop irregularly at different period of 37 the year, which may not be desirable commercially.

To avoid this trees are given bahar treatment.

• In this treatment, the irrigation is withheld two months prior to the bahar followed by light earthing up in the basin. This facilitates the shedding of leaves.
• The trees are then medium pruned 40-45 days after withholding irrigation.
• The recommended doses of fertilizers are applied immediately after pruning and irrigation is resumed.
• This leads to profuse flowering and fruiting. The fruits are ready for harvest 4-5 months after flowering.
  In tropical condition, there are three flowering seasons,

1. January-February (Ambe bahar)
2. June -July (Mrig bahar)
3. September-October (Hasta bahar).

The choice of flowering or fruiting is controlled by the availability of irrigation water, market demand, and the prevalence of pests and diseases in a particular area.

Objectives-

• To obtain an appropriate crop at the desired season.

• Control fruit production for consistency and quality.

• To increase both productivity and the grower’s profit.

• To lower cultivation costs because continuous uninterrupted blossom would result in light crops all year long and expensive monitoring and marketing expenses.

Mrig Bahar

• In Deccan regions, when water is so limited in the summer, Mrig Bahar is practised
• Withholding watering for this treatment from December to April may result in significant growth inhibition. As the plants enter their dormant state in the months of march through April, leaves are shed.
• Before the rainy season begins, manures and fertilizers are sprayed, and light irrigation is followed by two significant irrigations spaced seven days apart.
• Trees will grow rapidly within 15 days, producing fruits and flowers and new growth. Fruits start to ripen in October and keep doing so until December.

Ambe Bahar

• Ambe Bahar is practised in regions where water is available during hot weather. After the start of the wet season, no irrigation is provided, and the fruits are available in June and July.
• Manures are sprinkled in December and January. The first irrigation is provided in January, and within a month after this irrigation, flowers start to bloom.
• Ambe bahar has been discovered to be a more effective treatment than mrig bahar in the dry regions of western Maharashtra.

Hasta bahar

• Hasta Bahar is rarely practised. August through September must be used to make the trees dormant.
• This treatment is used from September to October, immediately following the end of the rainy season.
• The earlier rainy season causes the plant to accumulate more nitrogen and the soil to retain some moisture, preventing the plant from experiencing the water stress needed to promote flowering.
• Well-draining soils may be regarded as favourable for this treatment.
• This treatment is popular because it guarantees a high market price for the fruits.
• The fruits of hasta bahar have very appealing rind (skin) and dark-coloured arils, and they are picked from March through April.
• Fruits are expensive because there is a restricted supply during this season.
• Due to the timing of the irrigation restrictions and the rainy season, optimal water stress cannot be created during this time.
• Poor flowering results from this, which lowers the crop’s yield

• Water is withheld for two months before regular flowering, the roots are exposed, and pesticides are used.
• This process is referred to as Bahar Treatment
• Irrigation is withheld two months prior to the bahar.
• In case of light sandy and shallow soils, withhold water for 4–5 weeks.
• Such results in water stress, leaves show wilting and fall on the ground
• Application of ethrel spray at 2 to 2.5 ml/l mixed with 5 g/l of DAP
• The trees medium pruned 40-45 days after withholding irrigation
• Cover the roots with a mixture of soil and FYM and give light irrigation

1. Black spot / fruit rot : (collectotrichum gloeosporoides)

Symptoms : 

• The disease starts as minute dull-violet black spots on leaves. 
• The area surrounding the  spot turns yellow, then spots enlarge and cause drying.

Management : 

• Spraying fruits with 0.25% mancozeb or copper oxy chloride 0.25% or carbendazim  0.1% starting from one month after flowering and repeated at monthly interval (3 sprays). 

2. Bacterial leaf spot : (Xanthomonas campestris pv. punicae)

Symptoms :

• Optimum conditions are 77° to 95° F with night temperatures above 61° F, and a relative humidity of 90-95%.
• The affected fruits showed small irregular black spots, which later on coalesced into big spots.

Management-

• The diseased fruits should be collected and destroyed.
• Two to three spray at 15 days interval with Mancozeb 0.25%.

4.Alternaria fruit spot: Alternaria alternata

• Alternaria fruit rot infections commonly begin in the orchard following rain during flowering and early fruit development
• The most favourable conditions for Alternaria is rain or heavy dew occurring when temperatures are between 25-28°C.

Management-

• All the affected fruits should be collected and destroyed.
• Spraying Mancozeb 0.25 % effectively controls the disease.

5.Wilt: 

Management-

If infestation is observed, do drenching of Carbendazim@5gm/5Ltr to infected plant also other plants surrounding diseases plants.

• The propagating materials such as ground layers, grafts, rootstocks used for grafting, clones and rooted cuttings infested with root knot nematode, M.incognita in pomegranate act as sources for dissemination of these nematodes into main field.
• Use of air layers and sterilized soil media or adopting soil less media (vermiculite and coir pith) can keep the nematodes from entering the root system at nursery stage.

20-25 t /ha/year

The fruits can be stored up to 6 months at 0 to 4.5°C and 80% RH.
