Used substrate media have easy to find locally and not expensive with suitable fertilizer. So that, this experiment was to study effect substrate media with fertilizer on growth and yield of Cannabis variety Thai stick at the Faculty of Technology and Community Development’s research field and laboratory room, Thaksin University Phatthalung Campus. July - October 2022. Complete randomized design (CRD) was designed to include four replications and used growing mediums top soil : cow manure : rice husk ash : coconut flakes in the volume ratio of 2 : 1 : 0.5 : 0.5 with 4 different treatment fertilizer for comparison : treatment 1 no fertilizer (Control) treatment 2 Cow manure at 3,000 kg/rai (CM) treatment 3 Chemical fertilizer (15-15-15) at 25 kg/rai+Urea fertilizer (46-0-0) at 25 kg/rai (CF+Urea) treatment 4 Cow manure at 1,500 kg/rai+Chemical fertilizer (15-15-15) at 12.5 kg/rai +Urea fertilizer (46-0-0) at 12.5 kg/rai (CM+CF+Urea). The result demonstrated that treatment 1 provided the best results, generating a mean figure of stem height (265.75 cm.), stem diameter (2.14 cm) and number of node (41.50 node) showed the significant difference and higher than other treatment, canopy (2.26 m2), total fresh weight (1,027.28 g/plant) and total dry weight (447.47 g/plant) but did not differ significantly. Therefore, cannabis variety Thai stick was grown with used growing mediums top soil : cow manure :rice husk ash: coconut flakes in the volume ratio of 2:1:0.5:0.5 and no fertilizer can be used as a substrate media to promote growth and yield of cannabis variety Thai stick.
