More than 236,000 acres of rice fields spanning 160 miles once covered coastal South Carolina, according to a recent mapping project that used modern tools to document the massive footprint of the ...
This means when a field where rice is growing floods, accelerated growth in the internodal of the stem allows the plant to keep some of its foliage on top of the water. The O. s. indica cultivar is the main type of deepwater rice, although varieties of O. s. japonica have been found in Burma and Assam Plains .
