    • Duration 110-120 days, seed weight around 400mg
  • Soil
    • All types of soil
    • Poor to fertile
    • Well drained soil is more suitable since sensitive to salinity and alkalinity
  • Field preparation
    • As for other pulses except rice-fallows

      • Soil moisture availability decides the time
      • Delay in sowing end with terminal drought
  • Seed rate
    • Depends up on the size of the seeds & spacing
    • French bean : 120-140 kg (350-450mg)
  • Method of sowing
    • Broadcasting and planking
    • Drilling manually
    • Seed drill sowing

     

  • Depth of sowing
