1. HIGH DENSITY PLANTING
(HDP) & ULTRA HIGHDENSITY
PLANTING (UHDP)

2. HIGH DENSITYPLANTING
High Density planting means to
increase the plant population per
unit area for increasing the
production of fruit crops
 To overcome low productivity
 To reduce gestation period for
early

3. TYPES
Semi-intensive: 500-1000 trees/ha
Intensive system: 1,000 to 10,000
trees/ha
Super-intensive system: 10,000 to
1,00,000
trees/ha

4. PLANTING DENSITIES
 Low HDP: <250 trees per ha
 Moderate HDP: 250-500 trees per ha
 High HDP: 500-1250 tree per ha
 Ultra HDP: >1250 trees per ha
 Super HDP: 20,000 trees per ha (in Apple Orchards)
 Meadow Orchard: 70,000 trees per ha (in Apple &
Guava)

5. COMPONENTS OFHDP
Use of dwarf scion varieties.
Adopting dwarfing rootstock and inter-
stocks.
Efficient training and pruning.
Use of plant growth regulating chemicals.
Suitable crop management practices.

6. PLANTING SYSTEM FORHDP
• Rectangular with single, double or three rows
are followed
• Single row: row spacing is wide: 4X2m
• Double row: Wider spacing: (4+2)X2m
• Three row: More wider spacing: (4+2+2)X2m
• Bed System (or) Meadow orchards: A bed of
10-15 rows is closely planted (30X45 cm) and
separated by alleys of 2.5m width between
beds

7. ADVANTAGES
Best utilization of land and resources
Quality production of fruit crops
Increase in yield per unit area
Easy for intercultural, plant protection
and harvesting
Obtain export quality of the harvest

8. DISADVANTAGES
• Less life span of the fruit
• Difficult to manage the tree canopy
• Require high level of technical know-how
for the maintenance of fruit trees

9. HDP FORBANANA
Spacing: 1.2X1.2 m (or) 2.1X2.1 m
3 Suckers per pit~ Pit size: 50X50X50
cm
Pit spacing : 30-45 cm
Cavendish: 1.8X3.6 m (4600 plants
per ha)
Nendran: 2X3 m (5000 plants per ha)
Plant density: 4444 to 5555 plants per
ha

10. BENEFIT
S
33% more plant population
44% reduction in labour cost
37.5% decrease in fertilizer
cost
BCR=4.49:1

11. UHDP FORMANGO
 Amrapalli: 2.5X2.5 m spacing (suited for North India)
 Spacing Recommended: 4.5X4.5 m (or) 3X2m (or) 3X1m
 Dwarfing rootstock for Alphonso: Vellaikolumban
(Polyembryonic)
 For Fruit set during off year: Applying Paclobutrazol (Curtal)
1-2 ml per tree along with 10 litres of water (Growth
Regulator)
 Training the Mango tree by removing the tip at 2.5’ height to
produce
3 branches growing different direction to form umbrella like
structure
 Pruning is done to remove dead, diseased and unwanted

12. VARIETIES
SUITABLE
• Amarapalli
• Alphonso
• Dashehari
• Banganapa
lli
• Imampasa
nt
• Bombay
• Bangalura

13. Benefits
 Easy management because the height of tree is only 7’
 Reduced labour cost
 Effective utilization of scarce land
 Under Conventional Cultivation plant density is 40 tree per
acre but in HDP 200 per acre and in UHDP 654 per acre

15. MANAGEMENT OF MANGO IN HDP

17. PINEAPPLE HDP

18. MEADOWORCHARD IN GUAVA
 Modern method of High Density Planting developed by
CISH,Lucknow
 Shift of perception of farmers from production to productivity
 Densely planted orchards through judicious canopy
management and tree training system
 Suitable varieties: Sardar, Sweta, CISH G 5, CISH G 6, Lalit,
Allahabad Safeda, Hybrid seedlings
 Heavy usage of growth regulators and pruning

19. Different types of plantingin
Guava
System Spacing(m) Density(plant/ha)
Low Density 8x8 100-250
Medium Density 6x6 250-500
High Density 3x3 500-2000
Ultra- High Density 3x1.5 2000-5000
Meadow Orchard 2x1 5000-1,00,000

20. Advantages
 Commercial bearing from first year
 Average yield is 40-60 t/ha (Traditional method – 12 t/ha)
 Easy to manage due to small tree size
 Requires less labour
 Lower cost of production
 High quality fruit with good colour development
 Better utilization of Solar radiation and Increased Photosynthetic
efficiency
 Higher income
