Abstract
This research was done on 40-year-old ”Washington” navel oranges(Citrus sinensis (L.) Osbeck)during 2019–2020 and 2020–2021 seasons in light clay soil at a private orchard in Algharbia, Governorate Egypt. This study intends to assess how fertilizer applications of nitrogen and potassium nanoparticles affect the vegetative development, yield, and fruit quality of
Washington” navel oranges. Thus nine treatments with three replicates per
each were used in this study . This work was factorial experiment having two factors (Nano N or K) each with three concentrations e.i 0 , 600, 900
mg/l to stimulate the physiological processes and metabolism. Results indicated that treatments of nano nitrogen and potassium at a concentrated 900 mg/l. for each was greater in vegetative growth, yield, tree canopy and fruit quality such as , fruit number, and weight, fruit set
(%),peel thickness, juice volume, TSS, and vitamin C compared with all treatments while the treatment of (Nano 0.0 N + 900 K) only increased yield
efficiency compared to the control treatment which was the least
