To study the effect of biological promoters on morphology of Thymus daenensis Celak, this experiment was conducted in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran, in 2013. Experimental design was split plot in time in the form of a randomized complete block design with three replications. The main factor was biologic promoters in seven levels (0.75 and 1.5 L/ha of Humiforte, 0.3 and 0.6 L/ha of Aminoforte, 0.5 and 1.0 L/ha of Kadostim, 0.4 L/ha of Fosnutren, and control). The sub factor was harvest. Results indicated that biological promoters significantly affected plant height, canopy diameter, the number of flowering stems and fresh and dry shoot yield at P≤0.01 and canopy circle at P≤0.05. Harvest had significant effect on canopy circle, plant height, canopy diameter, the number of flowering stems and fresh and dry shoot yield at P≤0.01. Mean comparison showed that 0.5 L/ha Kadostim had the highest plant height (15.13 cm), dry shoot yield (1128.33 kg/ha) and dry shoot yield (3757.35 kg/ha). Application of 0.5 L/ha Humiforte resulted in the highest canopy diameter (36.53 cm). Mean comparison of harvests also showed that plant height (15.9 cm), canopy diameter (32.7 cm), the number of flowering stems (195.8), fresh shoot yield (3789.2 kg/ha) and dry shoot yield (1137.92 kg/ha) were the highest in the first harvest. Regarding the obtained results, it can be concluded that yield and yield components were the highest in the first harvest, when 0.5 L/ha Kadostim was applied.
