| Abstract | ||||
| This investigation was carried out for two seasons (2018 and 2019) on Valencia orange trees grown in sandy soil at Salhia area in Sharkia Governorate, Egypt, including three levels of chelated zinc compound. Each level was added at 1, 2, and 3 applications during the growing season. The recommended treatment with chelated zinc at 2g/l in March and June that caused a significant increase in yield and fruit size as compared with the other treatments. N, K, and Fe concentrations were decreased as the rate of a chelated zinc spray increased regardless number of sprays in general. Phosphorus contents showed insignificant differences between different levels of chelated zinc spray or number of applications. Mn and Zn contents were increased either level or by increasing the number of zinc sprays. | ||||
