Agronomic Practices

Field Preparation

  • Soybean should be grown in upland.

  • One deep ploughing once in every two years.

  • The depth of ploughing should not be more then 15 cms.

  • Ploughing should be followed by 1 or 2 light harrowing or 1chiselling.

  • PSB may be applied at 3.00 kg/ha as soil application.

  • The inoculants should be mixed with 150 kg soil/FYM/ compost and it should be broadcasted uniformly at the time of last harrowing before sowing.

  • If the field is having weed problem then stale seed bed technique can be used.

  • Let a heavy flush of weeds emerge and be destroyed with herbicide before sowing the
    crop, without any tillage on it.

Seed & Sowing

  • Seed treatment is very essential to prevent the crop from soil and seed borne diseases.

  • This should be done by treating seeds with 3 gms of Bavistin for per kg of seed.

  • The treatment of soybean seeds should be done before seed inoculation.

  • For seed inoculation the farmers should use Rhizobium culture at the rate of 5 gm per one kilogram (1.00 kg) of seed.

  • Seeds can also be treated with Trichoderma viridae and Phosphorus Solubilising Bacteria (PSB) at the rate of 5 gm per kilogram of seed.

  • For inoculation use freshly prepared peat based culture of Rhizobium japonicum.

  • For inoculation first moist the seeds with water and mix the culture uniformly in shade in required quantity just before sowing.

Harvest

  • Harvesting should be done only when the pods mature fully.
  • The plants have yellow leaves along with huge amount of leaf drop.
  • Soybean should be harvested at a moisture percentage of 12 - 14 %.
  • Soybean should be harvested in the morning or during early hours of the day to avoid shattering.
  • Shattering will be high under low humidity conditions.
