Abstract

This study was carried out during the 2021and 2022 seasons, Ewasy mango trees were sprayed once with 500 ppm Ethrel, 110 ppm Nano Carbon, and 110 ppm Nano Si+110 ppm Nano Zn to investigate the effect of Ethrel, Nano Carbon, and (Nano Si+ Nano Zn) on Growth, some blooming characteristics, yield, and chemical and physical characteristics of the fruits. Single and combined application of 500 ppm Ethrel, Nano Carbon, and 110 ppm Nano Si+110 ppm Nano Zn was very effective in enhancing growth characteristics, blooming characters, yield, as well as physical and chemical characteristics of the fruits compared to the control treatment. Using Nano Carbon and Nano Carbon+ Nano Si+ Nano Zn was preferable to using Ethrel and Nano Si+ Nano Zn to improve yield quantitively and qualitatively. The combined application of these materials surpassed each material alone in this respect. One spray of Nano Carbon treatment is responsible for producing higher yield and better fruit quality of Ewasy mongo trees. At the same time, the lowest values of yield and fruit quality were recorded on untreated trees in both seasons.
