French bean (Phaseolus vulgaris L)
YCD 1, Ooty 1, Ooty (FB) 2, Arka Komal (Sel.9), Premier, Arka Bold, Arka Sampoorna and Arka Karthik are popular varieties.
Ooty (FB) 2
Arka Komal, Premier, (Sel.9), Arka Suvidha, Arka Anoop, Arka Samrudhi, Arka Suman are under cultivation.
A well drained loamy soil with pH range of 5.5-6.0 with cool climate is suited for French bean cultivation.
About 80 kg/ha for hills and 50 kg/ha for plains are required
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.
Preparation of field
Dig the soil thoroughly and incorporate FYM and form beds of convenient size.
After two ploughing, form ridges and furrows.
In hills, sow the seeds (2 seeds/hill) in lines or in beds at a spacing of 30 x 15 cm. In plains, sow the seeds (2 seeds/hill) in the sides of the ridges at a spacing of 45 x 30 cm.
Irrigation is done immediately after sowing and again on third day and thereafter once in a week.
Application of fertilizers
Apply FYM 25 t/ha during last ploughing. 90 kg of N and P 125 kg of P/ha should be applied on one side of the ridges.
For rainfed conditions of Shevaroy hills, apply as a basal dose of 62.5 kg/ha of Phosphorous as super phosphate and with another half of 62.5 kg/ha Phosphorous as FYM enriched super phosphate.
Weeding should be given 20 – 25 days and 40 – 45 days after sowing. The crop should be earthed up after each weeding.
Aphids and thrips
Spray Methyl demeton 25 EC or Dimethoate 30 EC each at 1 ml/lit. In hills, glass house white fly occurs during May – August. Place 20 yellow sticky traps coated with castor oil in polythene sheet to attract the white flies.
Pod borer can be controlled by spraying Carbaryl 50 WP thrice at fortnightly intervals at the rate of 2 g/lit. Dust with Carbaryl 10 D at the rate of 2.5 kg/ha or Quinalphos 25EC @ 2 ml/lit.
Spray phosalone 35 EC @ 1.5 ml/lit.
Place 20 yellow sticky traps coated with castor oil in polythene sheet to attract the white flies.
Powdery mildew can be controlled by spraying Wettable sulphur at 2 g/lit or dust Sulphur at 25 kg/ha.
Rust can be controlled by dusting Sulphur at 25 kg/ha.
Anthracnose can be controlled by spraying Mancozeb at 2 g/lit or Carbendazim 1 g/lit or Chlorothalonil 2 g/lit.
Leaf spot can be controlled by spraying Mancozeb 2 g/lit.
Root rot can be controlled by drenching with Carbendazim 1 g/lit in the root zone.
8 - 10 t/ha green pods
TKD 1, KKL-I, Ooty 1, Murungai bean are popularly cultivated.
Cool climate with well drained loamy soils with pH range of 5.5-6.0 is suited for pole bean cultivation
February – March, July - August
About 50 - 55 kg/ha is required.
Treat the seeds with Rhizobium (4 packets/ha).
Land preparation and sowing
Prepare the land to fine tilth. Sow the seeds at a spacing of 20 cm between plants in double rows of 30 cm apart with the distance of 1.5 metre between each pair of rows.
Irrigation is done immediately after sowing, again on 3rd day and after once in a week.
Application of fertilizers
Apply FYM 25 t/ha, 90 kg each of NPK as basal. 45 kg each of NPK is applied as top dressing on 20 days after sowing.
Weeding and staking are done at 20 days after sowing.
Leaf hopper can be controlled by spraying Methyl demeton 25 EC or Dimethoate 30 EC at 2 ml/lit.
Pod borer can be controlled by spraying Carbaryl 50 WP 2 g/lit.
Remove the affected plants and spray with systemic insecticides to control insect vectors.
Powdery mildew can be controlled spraying Wettable sulphur at 2 g/lit or dust with Sulphur 25 kg/ha.
Rust disease can be controlled by dusting with Sulphur @ 25 kg/ha.
Remove the affected plants and pods and spray with Mancozeb 2 g/lit.
8 - 10 t Green pods /ha can be obtained.
