RAINFED RICE A SOURCEBOOK OF BEST PRACTICES AND STRATEGIES IN EASTERN INDIA
Advantages of transplanting
Assures establishment of plant stand
Lower seed rate
Weeds are controlled due to went cultivation
The crop gets more care in seeding stage
Disadvantages of transplanting
Seeding raising, uprooting and transplanting require
more time, labour and energy
Crop takes longer time to mature
Make strip beds and level the land property for uniform growth

Soak seeds in fungicidal solution
Transplanting
Transplanting is the practice of
raising the seedlings in a nursery
and transplanting them into a
separate puddled field. The crop is
grown without disturbing thereafter.
Preparing the seedbed
Productivity of the rice crop depends
on seedling health. To prepare the
seedbed:
1. The area should be one-tenth of
the area to be transplanted.
2. Complete one deep ploughing by
mouldboard plough three weeks
before sowing, followed by four
to six cross ploughings and
puddling.
3. Apply organic manure at 1 kg/
m 2 before the first ploughing to
incorporate it into the soil.
4. Puddle and level the land
properly. If necessary, make 1-2-
m-wide strips with a 30-cm-wide
drain channel between beds.
Level each bed again.
5. If a rotavator is used for
puddling, allow the soil to settle
for 24 hours.
6. Soak the seeds for 24 hours and
incubate them for 48 hours.
7. Soak the seeds directly in
fungicidal solution of Indofil M-
45/captaf/foltaf at 2.5 g/l of
water or Bavistin at 1.0 g/l of
water as a seed treatment.
8. Sow the sprouted seeds in the
nursery at 50 to 60 g/m 2
depending on the test weight.
9. Observe the beds and maintain
water in drains.
