This study was carried out to investigate the plant growth and mineral nutrient absorbance of Ardisia pusilla according to nutrient solution strength and hydrophilic polymer mixed in the media. Hydrophilic polymer in the trade name of K-SAM (Kolon Chemical Co., Ltd) was used and mixed with the media in the content of 0.1% (v/v, dry condition) into the plant pots. The plants were irrigated with the Sonneveld solution and the nutrient solution strength was manipulated to 0, 1/2, 1, and 2 times. The HR values of hydrophilic polymer K-SAM decreased to half as the nutrient solution strength increased two-fold. The range of pH values was between 6.7 and 7.2 with no significant difference among the treatments except for the treatment of N2P0.1 with 5.92. The EC values were higher in the hydrophilic treatments of N0.5P0.1 and N1P0.1 than control. It could be assumed that the retained mineral nutrients were leached in the distilled water during the measurement. The values of CC and TP were higher than control in the nutrient solution treatments except N2P0.1. The nutrient solution strength of 2 times limited the expansion of hydrophilic polymer so that no increased absorption of water than control could be observed. If the polymer was used with nutrient solution, nutrient solution of 1/2 times could be recommended. The nutrient solution strength of 1/2 times showed the best plant growth condition in almost all characteristics like plant height, volume, number of nodes, stem diameter, leaf number, and lateral branch length. There was higher mineral nutrient content of K in the polymer treatments supplied with nutrient solution. The contents of Ca and Mg decreased in all polymer treatments and especially in the highest nutrient solution strength of 2 times. The Fe contents also decreased in the treatments of nutrient solution strength with 1 and 2 times. Consequently, if the polymer was used with nutrient solution, nutrient solution strength of 1/2 times could be recommended. The nutrient solution strength of 1/2 times showed the best plant growth condition in almost all characteristics. The mineral nutrient contents in leaves decreased because of the nutrient solution supply, but no inhibition of the plant growth was found in this strength. Therefore, the use of the nutrient strength of 1/2 times is recommended as the most effective treatment to economize nutrient supply.
