How to recover crops after flood in Assam and prevent next year damage?

After flood, drain water quickly, clean silt off surviving plants, and assess what can recover versus what must be re sown. Once the field dries to workable condition, top dress nitrogen in splits to revive tillering since floods leach nutrients, and watch closely for blight, sheath rot and pests in the humid aftermath. For long term planning in flood prone Brahmaputra belt, keep flood and submergence tolerant paddy seed ready, raise nursery on higher safe ground, time sowing so the crop matures around the flood window, and consider raised beds for vegetables. Diversify with post flood short duration crops and pulses on receding water. Report damage promptly to the agriculture and revenue officials and your crop insurance for assessment.
