some semi pole varieties which are short day
types.

• Germination % - 85%
Soil:
• Sandy loam with good drainage & irrigation
• Suitable ph is 5.5-6.5

9. Propagation
• French bean usually propagates from seeds
• Season
Hills
March- April
Plains (twice)
July- September &
January- February
10. Field planting
Land preparation
Plough and loosen the soils to 15 - 25 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.
12. Planting
Plant 4 seeds in 1 planting hole and spacing between
rows is 90 cm and 30 cm between 1 planting hole to
another in pole type varieties whereas in case of bush
types spacing is 45*15 cm.
When the seedlings growing, leave only 2 plants in 1
planting hole.
In case of bush type varieties, about 60 - 65 kg/ha seed
is required.
In case of pole type varieties, about 25 - 30 kg/ha is
required.
13. SEED TREATMENT
• Treat the seeds with Trichoderma 4 g/kg or
Thiram or Carbandazim @ 2 g/kg of seed 24
hours before sowing to control fungal
diseases.
• If the crop is raised for the first time it should
be treated with Rhizobium as in cluster beans.
14. MANURES AND FERTILIZERS
• Apply FYM 25 t/ha during last ploughing.
• 100 kg of P/ha and 75 kg of k/ha should be
applied as basal dose before sowing.
• Being leguminous, apply only 60 kg of N/ha as
starter dose at time of sowing completely to
build population of symbiotic micro-flora.
15. WEEDING
• Weeding should be given 20 – 25 days and 40
– 45 days after sowing.
• As pre-plant used fluchloralin @ 0.5 kg/ha.
• As pre-emergence used alachlor @ 1.5 kg/ha
or Pendimethalin @ 2 kg/ha.
• The crop should be earthed up after each
weeding.
16. 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
17. 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

18. AFTER CARE
• Pinching out and Staking
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.
20. 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 : Bush type ( 80 – 100 q/ha )
Pole type ( 100 – 140 q/ha )
22. Conclusion
• French beans are sweet, tender and
wonderfully crispy.
• They contain zero fat and cholesterol and are
a good source of fiber and Vitamin C.
