 Scientific Name : Psidium
guajava
 Family : Myrtaceae
 Origin : Tropical America
 Chromosome No. : 2n=22,33
 Local Name : Amrood,

4.  Guava fruit, usually 4 to 12 centimeters (1.6 to 4.7 in) long, are
round or oval depending on the species.
 The outer skin may be rough, often with a bitter taste, or soft and
sweet.
 Varying between species, the skin can be any thickness, is usually
green before maturity, but becomes yellow, maroon, or green
when ripe.
 Guava fruit generally have a pronounced and typical fragrance,
similar to lemon rind but less sharp.
 Guava pulp may be sweet or sour, tasting something between pear
and strawberry, off-white ("white" guavas) to deep pink ("red"
guavas), with the seeds in the central pulp of variable number and
hardness, depending on species.
 Guavas are cultivated in many tropical and subtropical countries.
Several species are grown commercially; apple guava and
its cultivars are those most commonly traded internationally.

8.  In India, guava is well adapted in almost all the states and principally
produced in Maharashtra, Bihar, Uttar Pradesh, Andhra Pradesh,
Madhya Pradesh, Gujarat, Karnataka and Tamil Nadu.
 Guava contributes 4 per cent of the total fruit production which is
around 18.23 million tons from 182 thousand hectares.
 The productivity is around 9.9 MT /ha.
 Maharashtra is the leading guava producer both in area and production
followed by Bihar and Uttar Pradesh.
 But its productivity is highest in Karnataka followed by Punjab, Bengal
and Gujarat. However, overall productivity is far from its actual
potential.

16.  The self life of guava fruits at room temperature is only for a few
days. The mature fruits of winter season crop can be stored up to
6-9 days under ambient condition while those of rainy season
could be stored up to 2-4 days, depending upon the variety.
 With defined ventilation, the shelf life of guava fruits can be
extended up to 14 days under ambient condition. The low
temperature storage of fruits extends shelf life for another few
weeks .
 Under low temperature of storage of fruits at 10o C or below, this
temperature results in chilling to fruits.
 For low temperature storage, fruit should be hard, green and
mature but without colour break. Immature and ripe guava fruit
are not suitable for low temperature storage.

19. MARKETING
 Marketing plays an important role in transfer of ownership of
produce from farmer to middleman and ultimately to the
consumer.
 Efficient market should lead to higher income to the grower,
reduction in the margins of the intermediaries and prevention in
the glut situation resulting into crashing of price.
 The country is an advantageous position as it has two distinct
guava marketing seasons, viz rainy and winter seasons.
 Besides, the country is endowed with deep red surface colour
cultivars and pink flesh colour cultivars. The red surfaced
cultivars are very good in apparency and could be marketed as
fresh fruit, while the pink fleshed cultivars could be exploited
extensively for domestics as well as export market on a
sustainable basis.

wrap packaging of guava and it
can be successfully stored for 12
days under ambient condition as
against 5-7 days of unwrapped
ones.
