Abstract

A field experiment was done at privet Farm in Taha El-Marg Village, Diarb Nigm District, Sharkia Governorate, Egypt during the 2021/2022 and 2022/2023 seasons. Thus, to evaluate the influence of various phosphorus fertilization rates (0.0, 15.5, 31.0 and 46.5 kg P2O5/ feddan), biomagic rates (0.0, 3, 5 and 7 ml/ l) and their combined treatments on the growth and productivity of coriander (Coriandrum sativum L.) plants. The results referred that fertilized coriander plants with 31 kg P2O5/ feddan significantly increased plant height, branches count per plant and total plant dry weight compared to the other phosphorus rates. Moreover, the highest values of yield components (umbels number per plant and fruit yield per plant and per feddan) and production of volatile oil (volatile oil % and its yield per plant and per feddan) as well as total chlorophyll content, total carbohydrates and phosphorus percentages were produced with 46.5 kg P2O5/ feddan rate. Generally, the best treatment in all studied parameters of coriander was recorded when plants sprayed with 7 ml biomagic /l with significant differences with the other rates under study. In mostly, fertilized coriander plants with 31.0 kg P2O5/ feddan and sprayed with 7 ml /l of biomagic recorded the highest values in growth, yield and volatile oil production without significant differences between them. Finally, GS-MS analysis revealed that the major constituents of volatile oil were linalool, camphor, geraniol, alphapinene and gamma-terpinene.
