share
Abstract—There is increasing concern about human health and environmental contamination risks associated with the extensive use of mineral fertilizer. Organic matter is a fundamental in soil, but dynamic component of soils that influences the many chemical, physical and biological properties that regulate soil productivity. Objective of using humic substances in plant is to balance vegetative and reproductive growth as well as to improve yield. This experiment was conducted to complete randomized block design with four replications at Islamic Azad University Shahr-e-Qods Branch, Tehran, Iran. In this study, field trials were conducted to evaluate the influence of Humic Acid on the development and yield of yarrow (Achillea millefolium L.). Results showed that the Humic Acid significantly improved the development and yield. The finding may give applicable advice to eco farmer and agricultural researchers and the objectives of this study were to effect of Humic Acid on Essential oil and Flowering shoot yields in yarrow (Achillea millefolium L.).Keywords: Humic Acid, Essential oil, Yarrow and Sustainable Agriculture.
