- •
Dry seeding of boro crops in the High Ganges River Floodplain is risky.
- •
Cold damage in January will kill crops sown in November in at least 2% of years.
- •
Early November sowings emerged faster than late November sowings.
- •
Yield of BRRI dhan28 and 29 was maximum for 8–15 November sowings.
- •
Cultivars with greater vegetative cold tolerance are needed to enable dry seeding.
