Closed-cycle, open-cycle, and non-circulating hydroponic systems were evaluated for Agaricus bisporus (white button mushroom) cultivation. Sucrose-based and dextrin-based solutions were used as nutrient sources. The yield of mushrooms obtained from the closed-cycle system was 0.11 kg/m 2 for sucrose solutions and 0.43 kg/m 2 for dextrin solutions. The yield of mushrooms in the open-cycle system with calcium carbonate added for pH control was 1.92 kg/m 2 for the sucrose solution, while that of de-ionized water was 0.69 kg/m 2. The yields of mushrooms in the open-cycle system with antimicrobial compounds for the sucrose, dextrin, dextrin with peat moss, and de-ionized water were 1.8, 2.3, 2.1, and 1.5 kg/m 2, respectively. The non-circulating system, which utilized different concentrations of dextrin (10, 30, and 50 g/L), produced 2.96 kg/m 2 in the 30 g/L treatment, which was the highest yield recorded among the hydroponic systems. However, the yield of mushrooms from the non-circulating hydroponic 30 g/L dextrin treatment was lower than the yield of mushroom from compost (8 kg/m 2).
