1. High Density plantation of mango
• Mango showed a wide variation in flowering and
fruiting habit due to varietal differences and
diversity in agro-climatic conditions.
• Low productivity in mango is mainly due
1. To low plant population per hectare,
2. Absence of scientific methods of irrigation,
3. Inefficient nutrient management,
4. Improper orchard management practices
5. Losses due to pests and diseases.

2. High Density plantation of mango
• Mango, so far has been grown either this as
a crop with least management efforts and
without inputs like irrigation, fertigation etc.
• It leads to low productivity in mango.
• Increase the production of mango by
adopting the new hi-technology.

3. High Density plantation of mango
• Technology should be that , which gives more production
per unit area, for which the theme Ultra-high density
planting comes to forefront/ most important position.
• Mango cultivation can be revised by the adoption of ultra
high density planting system.
• This planting system can bring the changes a new era
/history where mango becomes quick, high, shrinking land
availability.
• Mature specimens can attain a height of 30 m and can
survive for more than 100 years

4. High Density plantation of
mango
• The root system consist of long, vigorous taproot and
abundant surface feeder roots.
• Both male and perfect flowers are found within a single
inflorescence.
• The flowers are cross pollinated by flies and honey bees.

5. High Density plantation of
mango
• Mango can be grown in a wide range of soils except clayey
or extremely sandy or rocky calcareous, alkaline or water
logged soils.
• It prefers a soil pH 6.5 to 7.5.
• Under HDP, Mango is planted at 3×2 m which
accommodates 674 plants per acre.

6. Care after plantation in High Density
plantation of mango
• Pit should be marked at 3×2 m before pit digging and pits
of 1×1×1m are to be dug at marked places.
• Alternatively one meter deep and one meter wide trench
can be prepared at every three mater.
• The pits should be allowed to weather for some weeks
before filling media.
• The same procedure is adopted as in other traditional
planting system.

7. Care after plantation in High Density
plantation of mango
• The bamboo/plastic pipes support essential to
newly planted grafts.
• The critical components of UHDP technology are
the management of inputs: irrigation and fertilizer
and besides the canopy management.
• These two inputs are provided through drip
irrigation systems.
• Management practices should be done care fully.

8. Care after plantation in High Density
plantation of mango
• Proper fertilizers, proper quantity and at proper
time should be adopted.
• Light irrigation in proper intervals according to
weather should be carried out.
• Training and pruning is most important in High
Density planation.

9. Benefits of UHDP in mango
• Increases productivity up to 2-3 times
• Reduces water used for irrigation up to 50
%
• Increases fertilizer uptake by plants when
fertigation is practised.
• Reduced the quantity up to 40-60 % of
fertilizers.
