This study aims to determine the best fertilizer treatment at vegetative stage for the growth and yield of rice submergence stress conditions on two types of swampy lowland. The experimental design used in this research was spilt-plot design with three replications. The main plot was fertilization treatment consisting of P1 = base fertilization, P2 = fertilizer before being submerged, P3 = fertilizer after being submerged + PPC Micro, P4 = fertilization before and after being submerged. The subplots are varieties of rice, V1 = Inpara 5, V2 = IR 64. The subplot was rice variety which consisted of V1 = Inpara 5, V2 = IR 64. The results showed fertilization treatment can increase rice production growth and submergence stress conditions, varieties of Inpara 5 added with fertilization before flooded can suppress a decrease in grain yield for 16 % in the shallow-back swamp and 6 % in middle-back swamps or with each production of 2.9 and 5.1 tons per hectare, varieties of Inpara 5 which is giving fertilization before flooded, tends to be a good treatment to be developed in rice submergence cultivation both in the the shallow-back swamp and middle-back swamps.
