Abstract : Echinacea purpurea is an introduced herbal growing natively in subtropical countries with optimal growing conditions of full sun exposure and low temperature. It has of biochemical compounds: alcamide, polyene, caffeic acid derivatives. E. purpurea can be developed potentially in the tropics, especially Indonesia, but the cultivation at lower altitudes will reduce the accumulation of biomass produced. The purpose is to provision of biochar and growth regulators of the auxin cytokinin group is an effort to develop E. purpurea cultivation, especially in the lowlands in increasing yield components and total flavonoid compounds. The research using Split-plot design consist of biochar (husk charcoal, wood charcoal) and growth regulator concentration (0,2,4,6 ml/L). The results showed that application of both the biochar and growth regulator that can effect the morphological characters and yield result E. purpurea. Treatment of both husk charcoal and wood charcoal at 6 ml concentration provided optimum yield in extract (6.07%) and flavonoid total (0.596%). Variables of morphological characters and yields are interrelated with each other. The coefficients of correlation between wet, dry and harvest index are 0.660 (strong correlation) and 0.394 (medium correlation) at a very significant level. The correlation between variables component yield and flavonoid level of E. purpurea was very significant with a strong correlation level of 0.756. The treatment of auxin cytokine growth regulators has an effect on yield components and total flavonoid accumulation compared to the type of biochar given.
