ABSTRACT
An alternative way to increase rice production in Indonesia is through the use of tidal swamp areas. The potential development for agriculture in tidal swamp areas in the Jambi province reaches 39,538 ha. However, the development of this land is constrained by several factors, resulting in rice productivity of tidal swamplands still being low, with an average of around 3 tons/ha. These obstacles can be overcome through the implementation of water management and the use of new high-yielding varieties of rice for tidal swamplands. The study aimed to determine the effect of two water management models on two new rice varieties favored by local farmers/residents and was carried out on farmers’ land areas covering more than 3 ha. Through the introduction of tidal rice cultivation technology and by observing the growth and yield parameters of rice production, the rice production will hopefully increase. The results showed that the one-way water system model was generally slightly better than the two-way water system in the rice cultivation activity. Rice growth such as plant height, number of tillers, and yield components showed that the Inpara 2 variety gave high outcomes of 5.9 tons/ha that tended to be better than other varieties.
