Abstract: This study was conducted to examine an alternative cultivating method that uses coir substrates in a hydroponically cultured system.Three treatment conditions were applied with one-layer substrate (10 cm height) with a coir chip and dust ratio of 5:5 (Treatment A), two-layer coir substrate (20 cm height) with a coir chip and dust ratio of 5:5 (Treatment B), one-layer coir substrate (15 cm height) with a coir chip and dust ratio of 7:3 (Treatment C).The control condition was a plastic container filled with a coir chip and dust ratio of 5:5.Various criteria were measured and compared between the treatments and the control.The yield of strawberry was smaller in the control than in the treatments.No significant difference in growth characteristic was found in the height treatments of the coir substrates.The net photosynthetic rate of the treatments was 14.68-15.76µmol CO 2 •m -2 •s -1 .This does not show a statistically significant difference.The root activity was better in treatment B and C than in treatment A and the control.The length and width of leaves were measured as 4.04-4.13cm and 3.26-3.34cm.These results are not statistically significant.The leaf length and width ratio was 1.27 in the control and 1.24 in the treatments.The findings show that no statistically significant benefit was found when utilizing coir substrates with different height treatments in the hydroponic culture system.However, the harvested fruit per plant weights 72.38 g in treatment A and 48.69 g in treatment C. The number of harvested fruit was least in treatment C in which a coir chip and dust ratio of 7:3 was applied.Therefore, further research is needed to examine how the chip and dust ratio in coir substrate affects growth characteristics.
