• Israel has a warm Mediterranean climate.
• However a wide range of climatic conditions
allows growing diverse fruit species:
• Deciduous trees: apple, pear, cherries,
stone fruits, grape, pomegranate, fig and
persimmon
• Subtropical: citrus, avocado, mango,
litchi, banana and date palm.
• We invests considerable efforts in the
development of fruit production, suitable for
cultivation under different conditions.

Mango in Israel - History
• Mango is a rather new crop to Israel.
• It was brought approximately 120 years ago from
Egypt.
• Most “Modern” (Floridian) mango cultivars were
introduced to Israel 90-100 years ago (1930-1940).
• Until the late 1960’s mango was not grown as a
commercial crop.
• Applied horticultural research, at the Volcani center,
the Faculty of Agriculture, together with extension
services and the growers enabled to transform mango
(as well as avocado) into a major crop.

Mango in Israel - climate
• Israel is one of the world’s most Northern countries
having commercial mango production.
• Lower temperatures during winter, and events of
frost limit mango orchards to restricted areas.
• Frost events usually occurs very locally and are not
completely predictable
• Even periods of several hours can cause severe
damages.

Mango in Israel - climate
Flowering and fruit settings
• Unpredictable weather conditions (both very warm
and dry events and cold periods) during spring are
not ideal conditions for mango flowering and fruit
settings.
• Lower temperatures affect development of early
inflorescences and inefficient fruit settings.

Mango in Israel - climate
• The warm and dry summer conditions during
fruit development and ripening enables high
quality fruits that are clean of diseases.
– No Anthracnose.
– No bacterial black spot disease
• Conditions enable densely planted orchards to
increase productivity.
Warm and dry summers

Water and irrigation of
mangoes in Israel
– Low quantity and quality of the water
– Salinity problems (water and soils)
– Dry season from April to October with
practically no rain
– Efficient drip-irrigation
– Irrigation of approximately 8000 m3 water per
year per hectare
![Page 20: The mango industry in Israel · manage mango malformation •Sanitation is the key for disease reduction •Buds can be protected from windborne inocula during the “infection window”](https://reader030.vdocument.in/reader030/viewer/2022011823/5ed695cd843ed9152066a860/html5/thumbnails/20.jpg)
Mango in Israel
– Calcareous soil
– Basic pH, above 8.0
– Iron and zinc deficiencies
– Supplementation with iron-chelates (up to 50-kg
/Ha/Year)
– Development of tolerant rootstocks

13/1 - a tolerant rootstock that enabled
commercial mango production
• Screened from seedlings originated in Egypt,
on the 1930’s by Prof. Oppenheimer.
• Became popular only on the 1970’s.
• Tolerant to basic soils (and somewhat to
salinity).
• Polyembryonic.
• Currently, more than 95% of Israeli mango
orchards are grafted on 13/1 rootstocks.

• Traditionally grown in several
regions in Israel.
• Transition to a main growing
region in the Northern valleys.
• Success in malformation
management leads to new
interest in mango cultivation in
previously affected regions of the
country, enabling expansion of
the ripening season.

Mango production in Israel
• Approximately 2,500 hectares.
• Annual yields 50,000 (60,000) tons.
• 40% of the fruits are exported, mainly to EU.
• Many new orchards are planted (more than
500 hectares in the last 5 years)
• Introduction and planting of new local
cultivars.

‘Maya’• Identified early on the 1930’s, out of a progeny of
‘Haden’ seedlings by Prof. Oppenheimer.
• Very tasty and juicy cultivar.
• Small fruit – 300 (200-500 gr).
• Mostly yellow with some red blush.
• Very short shelf life.
• Special protocols for marketing ‘Maya’ as a
ready-to-eat cultivars were developed.
