French bean, also known as kidney bean or snap bean, is a popular dietary food that is rich in nutrients. It is cultivated in several states in India, with major growing regions being Karnataka, Andhra Pradesh, Maharashtra, Tamil Nadu, Gujarat, and West Bengal. There are four cultivated species of French bean, with the most common being Phaseolus vulgaris. Optimal growing conditions include temperatures between 15-25°C and rainfall of 600-1500 mm annually. Seeds are treated before sowing and manure, fertilizers, and pest/disease management practices are followed for good crop growth and yield. Regular harvesting of young pods ensures continued flowering and yield of 80-140 q/ha

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.

19. Example…

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 )

21. Product

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.
