The current investigation evaluated the influence of organic amendments, specifically poultry manure (PM), and micronutrients, namely manganese (MnSO₄) and zinc (ZnSO₄), on the growth, yield, and chemical composition of coriander (Coriandrum sativum L.). Utilizing a split-plot design with three replications, the study assessed poultry manure as the main factor at four application rates: 0 (control), 3, 6, and 9 m³/fed. The secondary factor comprised five foliar treatments: tap water (control), MnSO₄ at 50 and 100 ppm, and ZnSO₄ at 50 and 100 ppm. The results demonstrated that poultry manure at 9 m³/fed significantly enhanced plant growth parameters, yield, essential oil production, and chemical properties compared to lower application rates and the control. Similarly, foliar applications MnSO₄ at 100 ppm improved plant development, encompassing height, branch number, herb dry weight, and fruit yield, along with essential oil content and chemical constituents. The most pronounced effects were observed with the combined treatment of poultry manure at 9 m³/fed and MnSO₄ at 100 ppm, which, across two consecutive growing seasons, increased plant height by 25.8% and 29.7%, branch number by 77.6% and 65.3%, herb dry weight by 134.8% and 116.3%, fruit yield per feddan by 128.6% and 100.2%, and essential oil percentage by 50.0% and 50.2%, respectively, relative to the control. These findings underscore the efficacy of integrating organic manure with targeted micronutrient applications as a sustainable strategy to restore soil fertility and optimize coriander production.
