Abstract Performance of rice on lateritic soil was studied under three levels each of soil submergence, soil fertilization, and soil manipulation in the two rice growing seasons, aus and boro. In both seasons the grain yield was better under submergence than under saturation. The crop under shallow submergence (5 ± 3 cm) yielded as much as under deeper submergence (10 ± 3 cm). The crop growth under soil bulk density of 1.68 g/cc or above, obtained through puddling or compaction, performed equally well. With the increasing level of submergence, the P, Fe, and Si contents of grains increased, but, Mn content decreased in the two seasons.
