摘要：This study aimed at studying the effects fertilization and submersion on morphological changes and production of two rice varieties with submersion stress conditions. The experimental design used in this research was randomized block design with three replications. The first factor is: Varieties (V): IR 64 (V1), Inpara 5 (V2). The second factor is the treatment (P): P0 = Without submersion, P1 = Submersion 7-14 dap and fertilizer N, P and K 7 days after being submerged, P2 = Submersion 7-14 dap and fertilizer N, P and K + PPC Micro 7 days after being submerged P3 = Submersion 7-14 dap and 28-35 dap and fertilization N, P and K 7 days after the first submersion, P4 = submersion 7-14 dap and 28-35 dap and fertilization N, P and K + PPC Micro 7 days after the first submersion. Results of the study showed the fertilization treatment after being submerged affected the morphological changes of rice crop with submersion stress conditions. Treatment of the fertilization N, P and K + PPC Micro 7 days after the first submersion give the best effect on the growth and yield of rice under submergence stress conditions.
