Background and Objective: Coriander (Coriandrum sativum L.), is an annual herb related to the Apiaceae family. Coriander is one among the prime vital sources of medicines as natural synonyms to synthetic components, used for cure of many human disorders, in cosmetics and as a flavored agent in food merchandise. The purpose of present investigation was to study the effects of foliar spraying of iron (II) sulphate (FeSO4) and potassium humate solely or combinations at different concentrations of them on different growth parameters as flowering, yield, essential oil content and chemical composition of coriander plants. Materials and Methods: This study was conducted in open fields for two seasons continuously to study the effects of FeSO4 and potassium humate on growth parameters, floral characteristics, essential oil content, chemical composition of essential oil, chemical constituents, the contents of chlorophyll a and b, total carotenoids, total carbohydrate (%) and nutrient contents of coriander plant. The layout of the experiment used was "factorial experimental" in complete randomized block design system with 3 replicates. Data recorded were subjected to the two-way analysis of variance according to Snedecor and Cochran. Results: The observed data cleared that spraying potassium humate and (FeSO4) gave high increasing on contents of chemical constituents (N, P, K %) in the herb and the seeds. Increased Fe (ppm) content in leaves and seeds also increased the total chlorophyll a and b, carotenoids, the total carbohydrates content, the herb essential oil yield in seeds and its chemical constituents (%) in comparison to the control plants in two successive seasons. Conclusion: Generally, both potassium humate and FeSO4 together are perfect fertilizers for good growth of the coriander herb and seed yields with suitable content of essential oil.
