Abstract:
Background and Objective: Among many plant nutrients, potassium (K) stands out as the strongest influence on quality attributes that determine fruit marketability and consumer preference. Thus, the aim of this study was to improve leaves nutrients status and fruit quality attributes of Sultani fig cultivar grown in South Sinai of Egypt. Methodology: At two-seasons of study (2014 and 2015), different potassium forms at i.e., nitrophoska (slow resale fertilizer), potassium nitrate, mono potassium phosphate and potassium sulphate at different concentrations (0.5 and 1%) were used. Fig leaf area, nutrient status were measured. Fruit quality characteristics such as fruit weight, volume, moisture content, total soluble solids, total acidity and ascorbic acid content were assessed. Fruit skin and flesh colors (L*, C and H°), Total phenolic and total anthocyanin were also determined according to A.O.A.C. Data were analyzed with the two way ANOVA procedure of M-STATC program V.3.1., treatments means were compared by Duncan’s multiple range tests at 5% level. Results: The obtained results revealed that all potassium forms with different concentrations reinforced nutrient status, fruit physical and chemical characteristics compared with control trees. Conclusion: Potassium nitrate at 1% and nitrophoska at (0.5 and 1%) were the best treatments to increase leaf area and its nutrients content. Moreover, they also improve fruit quality as well as physical and chemical properties.
