Abstract

The effects of different vermicompost and hog manure rates on growth, yield, total flavonoid and phenolic content, antioxidant activity of Agrimonia pilosa Ledeb (AL) were investigated. Nine treatments were applied, combining vermicompost (VC) with hog manure (HM) at rates: 0 + 0 (control treatment, T1), 0 + 11.25 (T2), 0 +16.875 (T3), 12.5 + 0 (T4), 12.5 +11.25 (T5), 12.5 + 16.875 (T6), 25 + 0 (T7), 25 +11.25 (T8), 25 +16.875 ton ha-1 (T9). The results demonstrated that pH between 6.9 and 7.4, EC from 0.5-0.6 mS cm-1 are optimal for herbal growth. Additionally, P2O¬5, K2O5 and Mn had coherent coefficient with herbal quality. A mixture of the VC and HM made with the rate of 12.5 + 16.875 ton ha-1 produced best parameters and is therefore recommended that these fertilizers served as potential source of nutrient for the AL. Further detailed investigations of them for other herbs are in progress.

Conclusion

In conclusion, this study provides scientific proofs for benefits of organic fertilizer application in herbal productions. It may be concluded that VC and HM could be seen as great potential component of growing media. Our results reveal that pH between 6.9 and 7.4, EC from 0.5-0.6 mS cm-1 are good for growth, yield and pharmaceutical quality of AL, which is an important characteristics in AL production. In addition, application of VC and hog manure (12.5 +16.875 ton ha-1) mixture produced the highest parameters of this herb and is therefore recommended.
