Tillering, Lodging and Yield under Deep Water Treatment in Direct-seeded Rice

Effects of Deep-Flooding Irrigation on Growth, Canopy Structure and Panicle Weight Yield Under Different Planting Patterns in Rice

“…We reported that the culm diameter was markedly increased and the breaking strength of the basal internodes tended to be increased by deep-fl ooding treatment (Ohe et al, 1996). Won et al (1999b) also reported the thicker culm and heavier culm breaking weight in deep-water treatment somewhat contributed to the reduction of culm-breaking lodging in direct-seeded rice. The increase in lodging resistance in this study was interpreted as the basal internode diameter increase.…”

“…The increase in lodging resistance in this study was interpreted as the basal internode diameter increase. On the other hand, Won et al (1999b) reported that the lodging degree was also affected by the cultivation method i.e., transplanting, dryseeded and water-seeded, and that in water-seeded cultivation, soil surface sowing of the seeds led to serious root lodging. From this point, deep-fl ooding irrigation is thought to be effective for solving the lodging problems of direct-seeding cultivation, but special precaution to the sowing depth would be needed.…”
