NPK nano-fertilizers enhance growth, oil quality, and yield regularity in Picual olive trees.

ABSTRACT: This study aimed to assess the impact of green-synthesized NPK nano-fertilizers (NPKNF) on the growth, productivity, and quality of the 'Picual' olive cultivar under Egyptian conditions. Foliar sprays of NPKNF at 0 (control), 2000, 3000, and 4000 mg L^-1 were applied during the "on-year" season. Evaluations covered vegetative growth, leaf and fruit mineral content, fruit traits, yield, oil and moisture content, and various olive oil quality indicators. In the following "off-year" season, flowering, fruit set, yield, and alternate bearing severity were also examined. Results indicated a significant enhancement in vegetative growth, fruit traits, yield, and oil properties during the "on-year" season in response to increasing NPKNF concentrations. The highest concentration (4000 mg
