Effect of Some Phosphate Fertilizer Sources and Phosphate Solubilizing Microorganisms on Yield and Quality of Flame Seedless Grapes
Year: 2025
Type: article
Abstract: The present study carried out during 2022 and 2023 seasons to investigate the effect of some phosphate fertilizer sources (superphosphate, triple phosphate, rock phosphate and orthophosphoric acid) either single and/ or in combination with some phosphate- solubilizing microorganisms (phosphorein, vesicular- arbuscular mycorrhizae (VA-M), phosphorein + VA-M, control (un-application on yield, cluster characters and some berry quality attributes of Flame Seedless grapes. There was a clear improvement in yield and berry quality characteristics in response to using the suitable phosphate per vine on four sources, 148.0 g RP, 277.0 g SP, 239.0 g TP and 54.0 ml OPA, in ascending order. On the other hand, the combined inoculation of phosphorein and VA- mycorrhizae had significant increases in yield and quality of berries compared with those of phosphorein or VA- mycorrhizae as single and untreated ones. The combined treatment of phosphate sources and phosphate-solubilizing microorganisms seemed to be more effective than the single one.The best results for yield and fruit quality on Flame Seedless vine were obtained with a phosphorus fertilizer of 148.0 g rock phosphate plus 10.0 g phosphoric acid plus 10.0 g VA mycorrhiza per vine / year.
