MSU: Rice farmers can get same yield with 1/3 less water
STARKVILLE, Miss. (AP) - Some rice farmers can use much less water and get the same yield by flooding their fields at the start and end of the season, and letting them dry out a bit in between, Mississippi State University researchers say.
That’s a radical change from recommendations across the Rice Belt to keep two to four inches of water in the fields, irrigation specialist Jason Krutz said in a news release. Instead, he recommends letting fields dry until water is 4 inches below the soil surface, then re-flooding them.
