The development of shallots in tidal land needs to be carried out considering the availability of land and the demand for shallots, which continues to increase, so it is necessary to develop suboptimal land. Adaptive shallot varieties and soil and water management are key to agricultural cultivation in tidal swamps. This research was conducted in the tidal area of Mulyasari Village, Tanjung Lago District, Banyuasin Regency, South Sumatra, from April to June 2023. This study used a 2-factor Completely Randomized Design (CRD). The first factor is the use of varieties (V): the Bima Brebes variety, the Batu Ijo variety, and the SS Sakato variety. The second factor was the applications of ameliorants and actinobacteria by coating (A): without ameliorants,  actinobacteria, actinobacteria + manure,  actinobacteria + manure + dolomite. The treatment combinations totaled 12 and were repeated three times, so there were 36 experimental units. The highest shallot productivity was obtained in treating actinobacteria + chicken manure + dolomite for the Bima Brebes variety, namely 8,42 tonnes/ha. Providing actinobacterial-enriched ameliorant affects the nutrient uptake of N, P, and K. Fe and Al can be chelated by providing actinobacterial-enriched ameliorant so that shallots can produce quite good production in tidal fields with water-saturated cultivation varieties.
