Rainfed rice - IRRI books - International Rice Research Institute

Utilisation and Management of Natural Resources in Rainfed Areas
double transplanting/splitting of tillers from surviving crop to
compensate for the damaged area;
sowing of extra early rice varieties; and
transplanting of aged (50-60 days) photoperiod-sensitive seedlings in
post-flood conditions.
Submergence/water stagnation
Restoring yield loss due to reduction in plant population through
use of long-duration submergence-tolerant variety;
advancement of planting with sub-surface water; and
planting of aged seedlings/split tillers to cope with complete or partial
submergence.
Deepwater-prone
Managing total damage of rice
plant for deep flooding through
flood-tolerant variety use;
shift to boro (summer) rice in
flood-free dry season;
floating rice-boro integration;
and
rice-fish cultivation.
Coastal flooding
Restoring yield loss due to salinity
through
planting of salinity-tolerant
varieties;
transplanting aged seedling in
submerged land;
using rice-fish cultivation; and
planting boro (summer) rice with
backfed water.
