  8. Planting • Pit of 1m3 size dig during September- October • Planting done during February- March • Spacing • Normal - 6x6 m • Medium HDP -4x4 m • HDP -3.5x 2.5-3.5 m • Pollinizer planted in every third row • Pollinizers- IXL, Jordanalo, Nee-Plus-Ultra, Waris 8
  9. Training and pruning • Open center system • At time of planting- headed back plant at 70 cm height • First branch allowed only above 0.6m • 3-4 scaffold branches selected (croch angle- 45-60) • Primary branches are headed back to ½ to 1/3 of the growth • Summer pruning in second year to form secondary framework scaffold 9
  10. Contd… • Third year dormant pruning • 2-3 secondary branches on each main branches are selected • Shoots growing inward and interfering with the main branches are pruned off • Almond bears fruits on spurs which remain fruitful for about 5 years • Pruning should be done in such a manner that one fifth of fruiting wood is removed every year • Unwanted water sprouts and suckers should be removed 10
  11. Manuring and fertilization 11
  12. Cont… • It is heavy feeder, require proper nutrition • N applied in 2-3 split dose • Half N and full P& K applied one fort night before expected bloom • 1/4th N- 3 weeks after fruit set • 1/4th N- June/July 12
  13. Irrigation • Irrigation done in an interval of 10-15 days • Critical stages • Flowering :February - March • Fruit development: April- June • Drip irrigation- 4L/hr for 5 hr at an interval of 4-5 days 13
  14. Flowering and fruiting • Flowering: January- April ,depending on cultivars • Bud differentiation: August- September, continue up to February • Inflorescence form on shoot and spur • Flower-perigynous, self incompatible • Pollination: cross pollination by bees 14
  15. contd… • Pollinizers in orchard -33% • 4-6 beehives/ha placed in orchard- 12-15% higher yield • Fruit growth in 3 stages • Stage 1-pericarp, seed, nucellus develops • Stage 2 endosperm and embryo enlarge • Stage 3-dry weight of embryo increases • Fruit is drupe 15
  16. Harvest • Bearing start from 3-4 year • Optimum yield obtained from 8-10 years • Harvesting time: August- September • Indices: hull split of 95% nuts • Harvested manually • Yield: 10-20q/ha shelled almond 16
  17. Post harvest management • Hulling- removal of hull from seeds • Done immediately after harvest manually or mechanically • Drying- to reduce mould growth during storage • Can be store more than 1 year at 0-7°C 17
