It is one of the popular fruit of India, according to
burton, in the early years of seventeenth century it was
found growing in India.
It is richest and cheapest source of vitamin – C (299
The ideal canopy shape should be such that it may meet
out as many as possible principles.
The perfect ideotype of guava is the canopy should be
dwarf, spreading, larger trunk, and open.
Canopy management is one of the most important fruit plant
This forms the basis of precociousness and longevity of the
fruit trees in an orchard.
The strong scaffold system help the trees to produce heavy crop
loads of quality fruits without any major limb breakage.
Regular annual priming is essential for the induction of good
amount of new growth.
which will provide the tree maximum fruit bearing area
uniformly over the whole tree.
Unpruned trees grow beyond limits provided for each tree in an
The tree size can be controlled by use of dwarfing
rootstock like Psidium friedrichsthalianum and aneuploid
While as triploid guava was found to increase the
vigour of Allahabad Safeda cultivar.
High density planting in guava has attracting attention
of many workers by using growth controlling root stock
and other canopy management practices like training and
Accommodation of the maximum possible number of the
plants per unit area to get the maximum possible profit per unit of
the tree volume without impairing the soil fertility status is called
high density planting.
The Meadow Orchard is a modern method of fruit
There is a shift in farmers' perception from production to
productivity and profitability.
Achieved through high density planting.
Recently, there is a trend to plant fruit trees at closer
spacing leading to high density or meadow orchard.
Higher and quality production is achieved from densely planted
orchards through judicious canopy management and adoption of
suitable tree training systems.
The Meadow Orchard is a modern method of fruit cultivation
using small or dwarf tree with modified canopy.
A comparison between meadow orchard system and the
traditional system of fruit growing is necessary to evaluate the
potentiality of this technique.
Low density planting Medium density planting High density planting
Attributes Traditional system Meadow system
Bearing fruits After two years From first year
Production Average yield is 12-20 t ha-1 Average yield is 40-60 t ha-1
Difficult to manage due to
large tree size
Easy to manage due to small tree
Requires more labour Requires less labour
Higher cost of production Lower cost of production
Large canopy, poor sunlight
penetration and poor quality
Small canopy better air and
sunlight penetration ,minimum
disease incidence and high quality
fruit with good colour

Training:- It refers to the practice of giving shape to the tree in
the initial year of planting to bear the load of crop in subsequent
Pruning:- “Pruning is the art of removal of parts of a tree,
especially shoots, roots, limbs, buds or nipping away of the
1. To admit light upto Centre of the tree and provide sufficient
movement of air across the plant.
2. To increase photosynthetic activity by exposing leaves to the
3. To provide strong scaffold system this could bear the heavy load
of fruits, without limb breakage.
4. To make hoeing, spraying, irrigation and other cultural practices
at a nominal cost.
5. To get balanced distribution of fruit over the tree.
Thinning out: When a shoot is removed entirely from the
inception so that, no new shoot arises from that place, it is referred
as thinning out.
Heading back: When a branch is cut almost to the base, leaving a
few inches of stump, carrying few buds, it is referred as heading
Restrains the vigorous vegetative growth of guava to manageable
sizes and forms thereby to achieve optimum production.
Increase productivity of orchards.
Stimulate precocious flowering of new plantings.
Extend the productive life of the orchard.
Increase air circulation in the orchard, which lowers losses
associated with diseases.
Maintain or reduce plant size.
Remove undesirable growth.
Remove dead, diseased, or broken branches.
Stimulate flowering and fruiting.
Rejuvenate and restore old plants to vigorous growth.
Prevent damage to life and property.
Shape plants in an artificial form.
Reasons to Prune
Secateurs Bow saw
Pole hand pruner
Pruned tree Un - pruned tree
1. Fruit size is large.
2. High productivity after 3-5 year.
3. Every year fruiting takes place.
4. As the size of tree is less, cost of
labour, insecticide and pesticide
5. If any natural calamity occurs, the
fruits are less damaged because of
their less height.
6. Due to the less height every tree
gets proper sunlight, spraying of
insecticide and pesticide can be
7. As the fruits are ready to harvest
10 – 15 days before, we can fetch
higher priced market.
1. Fruit size is small.
2. Low productivity.
3. Alternate bearing.
4. Cost of labour, insecticide and
pesticide increase because of huge
size of tree.
5. If any natural calamity occurs,
trees and fruits are damaged
because of their large size.
6. Because of their huge size, they
don’t get proper sunlight while
spraying of insecticide and
pesticide can’t be done properly.
7. As the fruits are ready to harvest at
the same time with other orchards,
fetch lower priced market.
Make senile orchards productive and juvenile
Adopt latest technology
Alter varietal composition
Enhance the profitability
Rejuvenation of Existing Orchards
Reduction in the photosynthetic surface area.
Non availability of productive shoots.
Increased incidence of insect pest and diseases.
Less penetration of sunlight.
Cutting should be done from lower
surface of the branch and later from
upper surface to avoid cracking as
well as bark splitting.
Large upright branches and trunks
should be cut on a slight angle.
Large branches and main trunks
should be cut off in sections.
