Nano-Materials Effect on Improving the Productivity of Pomegranate (Punica granatum L.) Wonderful Cultivar Under Saline Stress

Abstract

Background and Objective: Salinity is the most limiting factor for growth and production in pomegranate trees in the newly reclaimed lands this study aimed to alleviate the adverse effect of salinity on pomegranate wonderful CV. which grown under salinity stress and improve vegetative growth and fruit quality by using some of Nano-materialʼs fertilizers as a foliar application. Materials and Methods: This investigation study carried out during two successive seasons (2019 and 2020) at a private orchard located in the desert of West Minia Governorate the pomegranate trees were at vigour status and selected by choosing 21 trees (seven treatments and each treatment was replicated three times) the chosen trees were 5 years old, cultivated 3×4 m, irrigated with drip irrigation system, all trees were free of pathogens and physiological disorders and took all agricultural processes and fertilization treatments except the foliar application of examined materials. Results: Application of Nano silicon with Nano clay was better than using silicon with clay together.The use of silicon at Nano size was significantly more than using silicon at normal size while Nano-clay treatment and clay treatment were non-significant compare to control. The examined Parameters were leaf nutrient contents, fruit physical and chemical characterization and yield. Conclusion: Application of Nano silicon with Nano clay was the superior treatment in all of the parameters which have been examined.
