High density orcharding in fruit crops.

High Density Planting of Horticultural Crops By Dr. Suraj Prakash

1. High density orcharding in fruit
crops

2. High density orcharding is the practice of
accommodating higher number of plants of
the same species per unit area by planting at
a closer spacing than that is planted under
traditional system.

3. Increased sunlight capture per unit area
Land use efficiency
Appropriate vegetative reproductive balance
of the plants.

4. Low vegetative growth
Low productivity per plant

5. Planting system
Canopy management
Use of dwarfing rootstock/Interstock
Training
Shoot pruning
Root pruning
Use of growth regulators

15. Severe pruning in alternate rows every three
years

16. Possible strategy
Planting at a spacing of 5 m x 5 m
Shoot pruning in alternate years when fruiting is
not expected

20. No pruning Pruning to 60% of
canopy
Pruning to 80% of
canopy

30. For production of 1 kg of guava cv Sardar,
the total water requirement is 68.02 litre

37. Benefit cost ratio of Ultra High Density guava
orcharding for a period of 5 years is 3.1 as
compared to 2.9 traditional system
orcharding.
Net profit per year, fifth year onwards under
Ultra High Density orcharding is Rs.3.39
lakh/ha compared to Rs.1.68 lakh/ha in
traditional system

38. Keeping in view yield and gross income,
pruning of guava plants thrice a year viz.
March, May and October to 50% of shoot
length can be recommended for
maximization of income from Ultra-high
density guava orchard growing under Bihar
conditions.
Application of 60% of recommended dose
of fertilizer and irrigation at 60% PE was
found to be most suitable
