GUAVA
Common name:
GUAVA
Botanical name:
Psidium guajava L
Family:

Growing areas in Pakistan
In Pakistan, it is grown in all the provinces.
 The major guava growing areas in the
Punjab.
Shariqpur, Kasur, Lahore, Sheikhupora, Sangla Hills,
Gujranwala.
North West Frontier Province.
Kohat, Haripur and Bannu
Sindh.
Larkana and Hyderabad

Guava production in Pakistan
In Pakistan, it is grown in all the provinces over
an area.
58.5 thousand hectares
 with production of 468.3 thousand tones.

Cultural requirements
Guava grown under tropical and subtropical
climatic zones.
young plants are susceptible to drought and
cold conditions.
The guava does equally well on heavy clay, to
light sandy.
It tolrates a pH range from 4.5 to 9.4.

Propagation
Guava is propagated generally through:
Cuttings
Air layering
Grafting
Budding

Commercial Varieties
Safeda Allahabad

Cont…
Red fleshed Apple color

Production Technology
Guava trees are planted at a distance of 5-6
meters.
Trees grow rapidly and fruit in 2-4 years.
They live 30-40 years but productivity declines
after the 15th year.
Guava some time suffers from deficiency of zinc
and iron.
Spraying the trees with 7.0 gm per litter of
ZnSo4 and 46.5 gm of FeSo4 improves yield and
quality.

Pruning and Blossoming
Light annual pruning is necessary after every
harvest.
Guava flowers twice a year:
1st in March to April for summer crop.
2nd in August to September for winter.
. Blooming period varies from 25-45 days.

Cont….
Winter crop is usually preferred as it yields
higher with fruit of better quality.
Some of the growers adopt the practice of
having a good winter crop by with holding
water during summer.
Guava fruit takes about 125 days to reach
maturity after setting.

Harvesting
At maturity fruit turns from green to oil green
and at ripening creamy in colour.
Hand picking of ripened fruits two to three
times a week is suggested.
The harvesting season many last 8-10 weeks.
Fruit is highly perishable, it should be
immediately marketed after harvest.

Common Pests and Diseases
Rust (Puccinia psidii)
Orange to red pustules appearing on leaves, young shoots,
flowers and/or fruit; leaves distorted; defoliation of tree;
reduced growth; circular lesions on fully expanded leaves
with dark borders and yellow halos

Cont…
Management:
 Primary method of controlling
disease is usually the application of
appropriate fungicides.
 Cultural practices that may reduce
the incidence of the disease.

Cont…
Anthracnose( Colletotrichum gloeosporoides)
Sunken, dark colored lesions on mature fruit
which may become covered in pink spores.
lesions coalesce to form large necrotic patches
on surface of fruit.

Cont…
Management:
The primary method of controlling
the disease is to plant resistant guava
cultivars.
Both systemic and non-systemic
fungicides are effective at controlling
the disease.

Cont….
Algal leaf spot (Cephaleuros virescens)
Orange, rust-colored, dense, silky tufts on
both upper and lower surfaces of leaves which
turn reddish-purple in color as they mature.
 if tufts are scraped away, a thin gray-white or
dark-colored necrotic spot remains on the leaf

Cont…
Management:
Ensure trees receive adequate fertilization,
irrigation and and are properly pruned to
avoid stress on the plants and promote air
circulation through the canopy.
periodic applications of a copper based
fungicide is usually enough to control the
disease

Uses
Guava fruits may be eaten fresh or processed
to produce paste, jellies or preserves.
Dehydrated fruit is used to make guava
powder.
