The effect of organic manure and chemical fert ilizer on growth and development of Stevia rebaudiana Bertoni had been studied in experimental plots in Qingdao Agricultural University. The results showed that organic manure cultivation promoted root activity in 40 days after transplanting compared with the chemical fertilizer cultivation, and the dry weight of the above-ground has exceeded chemical fert ilizer cultivation in 60 days after transplanting. The glycosides synthesis and accumulation main period was in the later growth stage, and organic manure improved the root activity and enhanced the photosynthesis rate in later growth stage, finally the biomass of stevia and the content of glycosides were also increased.
