Hi
Agro-climatic requirements
Pomegranate grows well under semi-arid conditions and can be grown upto an altitude of 500 m. above m.s.l.. It thrives well under hot, dry summer and cold winter provided irrigation facilities are available. The tree requires hot and dry climate during fruit development and ripening. Pomegranate tree is deciduous in areas of low winter temperature and an evergreen or partially deciduous in tropical and sub-tropical conditions. It can tolerate frost to a considerable extent in dormant stage, but is injured at temperature below - 110 C.
Well drained, sandy loan to deep loamy or alluvial soils is suitable for cultivation.
Varieties
Important pomegranate varieties cultivated in India are Alandi or Vadki, Dholka, Kandhari, Kabul, Muskati Red, Paper Shelled, Spanish Ruby, Ganesh (GB I), G 137, P 23, P 26, Mridula, Aarakta, Jyoti, Ruby, IIHR Selection, Yercaud 1 and Co 1.
Pomegranate is propagated vegetatively by cuttings, air layering or gootee.
Air layering is usually done during the rainy season and also in November-December. Planting is usually done in spring (February-March) and July-August in sub-tropical and tropical regions respectively.
High density planting is adopted in temperate regions. A spacing of 5-6 m. in northern India and also in the plains of Deccan plateau is usually followed. High density planting with a spacing gives 2-2.5 times more yield than that obtained when the normal planting distance of 5 X 5 m. is adopted. Farmers have adopted a spacing of 2.5 X 4.5 m. Closer spacing increases disease and pest incidence.
The recommended fertilizer dose is 600-700 g. N, 200-250 g. P2O5 and 200-250 g. K2O /tree/year. Application of 10 kg. farmyard manure and 75 g. ammonium sulphate to 5 year old tree annually is adequate , whereas application of 50 kg. farmyard manure and 3.5 kg. oil cake or 1 kg. sulphate of ammonia prior to flowering is ideal for healthy growth and fruiting. The time of application is December/January for ambe bahar, May/June for Mrig bahar and October/November for hasthe bahar.
The basal dose of farmyard manure @ 25-40 cart-loads /ha. besides the recommended doses of N, P and K should be applied to non-bearing trees in 3 split doses coinciding with growth of flushes during January, June and September. Fruiting should be encouraged from fourth year onwards. Nitrogenous fertilizer is applied in two split doses starting at the time of first irrigation after bahar treatment and next at 3 weeks interval, whereas full dose of P and K should be applied at one time. These should be applied in a shallow circular trench below tree canopy not beyond a depth of 8-10 cm. After application, fertilizers are covered with top soil and irrigated.
