CROPS submerged for more than three days should be harvested immediately before they rot, says principal agriculture officer Uraia Waibuta.
Mr Waibuta said farmers should salvage whatever crops are left for consumption.
He advised farmers that it was ideal to plant short term crops like kumala as they mature in a span of three months.
Mr Waibuta added the farmers should allow the water to drain off their farms before they start planting crops such as dalo and cassava.
"Farmers are strongly advised to clean and clear their drains of all floating debris as this will clog up the drains and flood the crops that are planted in low-lying areas," he said.
"Farmers should also monitor their farms on a daily basis to avoid any outbreak of pests and diseases."
Farmers in the Northern Division are advised to plant rice once the weather clears in flood-prone areas because it thrives in such conditions.
Officials from the Ministry of Primary Industries are carrying out preliminary surveys to assess damage to crops and continue to monitor the situation.
Along the Wainibuka River, farmers counted their costs, saying they had never seen a flood as big as what they encountered in the past two days.
Last night, floodwaters continued to rise.
