Abstract

Effects of foliar spray of zinc and copper on the chemical fruit properties of pomegranate were studied during 2020 and 2021 seasons in a private orchard at Al-Badari, Assiut, Egypt. Zinc and copper were sprayed one time/ month, starting from April till October at the rate of 1, 1.5, 2 and 2.5% for each microelement under Randomized complete blocks design. Zn and Cu spray positively affected the TSS, acidity, TSS/acid ratio, total reducing, non-reducing sugars and vitamin C. According to the results, spraying zinc and copper significantlyimproved the chemical fruit quality of Manfalouty pomegranates.
