The research was conducted at the Rice Research Center, Sukamandi and at the Biotechnology Research Center,Bogor. A two factors factorial experiment was arranged on Split Plot Design, where three levels of submerging: saturated, 5 and 10 cm in depth were assigned as the main plot and three lowland rice genotypes: IR 64, S. 3254-29-21-2 and S. 3382-2d-16-3 lines as subplots. The results indicate that submerging revealed a significant effect on increasing the redox potential, pH, ethylene production, and yield, however decreasing weed infestation. Almost there was no significant difference among three genotypes on their ethylene, growth and yield, and also on their responses to the submerging treatment. Furthermore, submerging at 5 cm depth increased yield by 110 kg ha-I, or about 1.5 percent compared to just saturated condition. On the other hands, submerging at 10 cm depth increased yield by 612 kg-I. In term of varieties, the promising lines of S,3254-29-21-2 and S.3382-2d-16-3 did not prove to have a difference with ' IR 64, in terms of their tolerance to early submerging condition. , " Key words: Submnerging, Redox potential, Ethylene, Direct sfeeding system

Arable land-use conversion into activities of non-agricultural production may encourage the use of wet region for soybean production. In this respect, a research on the adaptability of 25 soybean varieties to saturated soil has been conducted in the field. A randomized complete block design with 3 replicates was used in this experiment. Results of the experiment showed the adaptability differences among the 25 soybean varieties tested. Based on their yield, soybean adaptability to saturated soil condition was not related to plant growth type, but could be influenced by plant age. With an exception for Tidar (a high yielding variety belonging to the intermediate age), the late varieties produced highe yield than that of the intermediate ones. It was concluded that the varieties belonging to high yielding ones were characterized by the existence of positive correlation of pod number with nodule number and relative growth rate and of nodule number with relative growth rate and leaves area index. Key words: Soybean, Adaptation, Saturated soil, Agronomic traits

Most farmers in tidal swamp areas usually grow local varieties with characteristics: adapted to tidal swamp condition, late varieties (9 to 10 month), photoperiod sensitive, very low potential yield (1 -2 ton/ha), specific grain size and accepted taste. Some farmers have grown improved varieties with high yielding ability and early maturity, but not of good adaptability to tidal swamp conditions, grain size and accepted taste. These are the reasons that the improved varieties can not establish on tidal swamp areas. The experiment was conducted on the peaty tidal swamp condition, and used 12 varieties and lines with Kapuas as control. Two lines had potential yield similar to that of the improved variety but the grain size and the taste acceptibility similar to that of local varieties. Key words: Rice, Tidal swamp
