This study was conducted to determine the cultivation technique to produce high quality herb of Agastache rugosa. Highest plant height, total chlorophyll content and net photosynthesis was recorded at 25℃ than at 15 and 30℃. Total chlorophyll content and net photosynthesis both shows decrease with the increase (30℃) and decrease (15℃) of temperature. Increase of temperature (30℃) causes early flowering but low temperature (15℃) delays the onset of flowering. Various growth and physiological parameters were studied under no shielding and different shielding conditions. Total chlorophyll content did not shoed any significant difference under different shielding percentage but net photosynthesis showed decreasing trend with increase in shielding percentage. Plant height and stem length showed significant increase at 30% shielding even over control (no shielding). The experiments on spacing between plants indicated that the length of herb and number of internodes increased with increase of spacing while number of green and matured plants decreased and its vice-versa. A. rugosa also checked for its growth parameters and oil content at low altitude and plane, our results indicate that the live weight and oil content of the plants is higher at low altitude area in comparison to plane. So it may be concluded that the cultivation of A. rugosa at semi-alpine is more suitable/beneficial for the production of high quality yield.
