Efectul îngrășământului Foliar pistachio mix plus NPA asupra randamentului și calității fructelor de cireș

The objective of the study is to determine the effect of the Pistachio Mix Plus NPA foliar fertilizer based on nanotechnology on the yield and quality of cherry fruits. The research was carried out on the Ferrovia cherry variety, grafted on Gisela 6, planted at a distance of 4x1.5 m. During the years 2022-2024, the foliar fertilizer was administered in 4 phenophases of cherry flower bud development in the dose of 2.5 l/ha. Applying Pistachio Mix Plus NPA in three phenophases (white-pink bud, petal shaking, beginning of budding), fruit yield increased by 14.423.5%, and their weight increased by 4-18.1% in the treated varieties in relation to the witness.
