Agro-climatological condition in Bengkulu is unsuitable and most areas have marginal soil characteristics for shallot cultivation. However, all shallot varieties were adaptable and grown on the cultivation area after the soil characteristics were ameliorated. Faced with unsuitable agro-climatic conditions such as too much rainfall, farmers should construct plastic shade or should adjust planting time during the closed dry season. Futhermore, all shallot varieties responded significantly to the chicken manure applied and 7 varieties involved Bima Brebes, Kramat, TSS Agrihort 1, Violetta 2, Violetta 3 Agrihort 1, Trisula, and Bauji significantly responded to the increasing doses of the manure applied. Bima Brebes and Violetta 3 Agrihort 1 showed the best yield performed by the shallot yields at 10 tons ha-1 of the chicken manure applied while Kramat, TSS Agrohort 1, Violetta 2, and Trisula showed the best yield at 20 tons ha-1 of the manure added. Furthermore, Bauji started to respond significantly at 20 tons ha-1 and increased significantly the yields when the increasing doses of the manure were applied. The highest yields of the shallot bulbs are grown on the irrigated marginal lowland in this area when the chicken manure was applied at 20 tons ha-1 which gave 20.996 tons’ ha-1 for the dry weight of the shallot bulbs.
