| Summary: | Jojoba plant (Simmondsia Chinensis (link) Schneider), or Ho-Ho-ba or goat nut is a shrub belonging to the Simmondsiaceae family. It is well known as a useful medicinal plant and as a new crop of interest for many industrial purposes. The present study was carried out duringhe two successive seasons of 2012/ 2013 and 2013/ 2014 in private jojoba farms located as following: El-Kassasin city, El-Ismailia, Marsa Matroh, El-Sharkia, Asuite and El-Khanka governorates(Egypt). The study focused on studying the effect of the different local growing site of Egypt on the growth and wax production, and aiming to detect the best location for the suitable growing site to produce the best growth and wax yield. Nine jojoba female shrubs were selected in each farm from the growing shrubs depending on its obvious morphological growth characters and the different seeds shape and then they were marked by labels for data measurements. The monthly temperature and relative humidity average during the study seasons of culture were taken and recorded. The physical and chemical properties of the experimental soil were also determined and presented. Growth and flowering characters of jojoba shrubs e.g. plant height and volume[S1] as well as flowering period and fruiting set were greatly altered in relation with the growing location. Indeed, plants grown in upper Egypt Asiut site tended to produce the best growth rate and the extended flowering. Moreover, plants cultivated in El Sharkia and Assiut sites gave the biggest yield of wax, compared to the other cultivation sites, while the lowest yield of wax was from plants cultivated in Marsa Matroh area. The best level of most of the fatty acid content (Palmitic, Oleic, Nervonic, Gadoleic and Erucic acids) was found in the wax extracted from seeds of shrubs grown in Ismailia growing site.
