• ORIGIN : America

4. Economic Important
• As a source of food
• As a raw material for production
• Sources of vitamin and minerals
• Provide job for local

5. CLIMATE & SOIL SUITABILITY
Climate :
• The temperature should ideally between
28-29 0C
• Rainfall between 600-1500 mm year
Soil:
• Sandy loam with good drainage & irrigation
• Suitable ph is 5.5-6.5

6. VARIETIES
KB, MKB 1, MKB 2
Royal Windsor
Remora
Tender Green

7. Propagation
• French bean usually propagates from seeds

8. Field planting
Land preparation
 Plough and loosen the soils to 15 - 22 cm deep
for good growth of root.
Prepare the bed with 1.2 m (4 ft) in width, 0.3 m
in height and the length will depend on the area
condition.
The spacing from 1 bed to another is 0.6 m.

10. Cont..
Planting
Plant 4 seeds in 1 planting hole, in 2 rows with
spacing between rows is 0.6 m and 0.5 m
between 1 planting hole to another.
 When the seedlings growing, leave only 2
plants in 1 planting hole. It is about 9.5 kg
seeds needed for 0.4 ha.

11. Preparation of stake
• French bean needs stake in order to obtain
high yield. Support the 3 week-old seedlings
using stake with 1.8 m - 2.4 m in length.
• Other method used to support the French
bean is trellis system. Join 2 sticks nearby to
the wire to form trellis.

12. Example…

13. General maintenance
• Fertilizing (1 ton / ha NPK Green)
• Pruning (for higher yield)
• Watering (to prevent dehydration)
• Weeding
• Tilling

14. Pest & disease
PEST SYMPTOM CONTROL
BEAN FLY
(Ophiomyia phaseoli)
The larvae bore on the
stem and causing plant to
wilt & die off
Spray with gamma BHC
Spray with carbaryl
LEAF HOPPER
(Aphis spp)
Live under the young
leaves, shoots & flowers
Vector for mosaic virus
 Malathion
 Endosuifan
 Diazinon
POD BORER
(Maruca testulalis)
The larvae bore into the
pods causing damage to
bean & flower
 Eradicate the damaged
bean
 spray sevin
 spray carbaryl

15. DISEASES PATHOGEN SYMPTOM
Leaf spot Colletotrichum capsici
&
Cercospora spp
 Yellow spot on the leaf
 Chemical spraying is not
required because it is not a
serious disease
Leaf rust Uromyces vignae  Yellowish on the leaf
Not affecting the yield of
long bean

16. Harvesting
• Pick the pods while still young and the beans have
not formed fully. More flowers will appear if picked
regularly
• Fruit can be harvested 7 weeks after planting
• Average yield is 8000 – 12 000 kg/ha

17. Product

18. Agro-industry processing and
added value
• French bean can be eaten as a vegetable.
• Process : Pluck from the tree
: Clean the french bean
: cut then fry

19. Nyumm!!

20. Marketing
