During the 2021 and 2022 seasons, Alphonse mango trees were sprayed once with 500 ppm Ethereal, 110 ppm Nano Carbon and 110 ppm Nano Si+110 ppm Nano Zn. Growth, some blooming characteristics, yield as well as chemical and physical characteristics of the fruits in response to foliar application of substances were Compared to the control treatment, single and combined applications of 500 ppm Ethereal, Nano Carbon, and 110 ppm Nano Si+110 ppm Nano Zn were very effective in improving the growth, blooming, yield, and physical and chemical characteristics of the fruits. Using Nano Si+ Nano Zn was preferable to using Ethereal and Nano Carbon to improve yield quantitively and qualitatively. The combined application of these materials surpassed the application of each material individually in this respect.  One spray of Si (110 ppm) + Zn (110 ppm) treatment is responsible for producing higher yield and better fruit quality of Alphonse mongo trees. While the lowest values of yield and fruit quality were recorded on untreated trees in both seasons.
