| Abstract | ||
| This study was conducted over two consecutive seasons (2022/2023) and 2023/2024) at the Farm of the Faculty of Agriculture, Al-Azhar University (Assiut Branch), Egypt, to evaluate the effects of two organic manure types (vermicompost and humic acid) and foliar applications of biostimulants (chitosan, amino acids, and dry yeast extract) on vegetative growth, yield, volatile oil production, and chemical composition of coriander (Coriandrum sativum L.) plant. Among five organic manure treatments, vermicompost at 5 m³/fed produced the best results, with plants showing the greatest number of branches, dry herb weight, fruit yield, and volatile oil quality. Foliar application of dry yeast extract at 10 g/l significantly enhanced vegetative growth, yield, volatile oil content, and chemical composition. The combination of vermicompost at 5 m³/fed and dry yeast extract at 10 g/l achieved the highest values of all recorded parameters, demonstrating a synergistic effect between both treatments that significantly improved plant performance. It is recommended that coriander plants could be treated with the combination of vermicompost at 5 m³/fed and dry yeast extract at 10 g/l to optimize growth, yield, and essential oil quality. | ||
