The characteristics of lodging resistance in hill-seeded rice were compared with those in broadcast-seeded rice at three different plant densities (40, 80 and 160 plants m-2) to study submerged direct seeding rice cultivation using a newly developed 'Shooting hill-seeder'. In the hill-seeded rice, the culm was longer than in broadcast-seeded rice, applying a strong force to the basal part of the hill.
