Abstract
This study was run out through 2019 and 2020 seasons at private orchard at Elwakff, Quena Governorate, Egypt to assess the effects ofpotassium different source fertilizer on the fruiting of Hayani date palm. The experiments were arranged in a completely random design with three replicates one palm each. Results showed that yield/ palm and bunch weight were significantly increased by treated with feldspar, bio (potassium solubilizing bacteria KSB) and potassium citrate. All treatments have a significant increase in the physical and chemical characteristics of the fruits. However, the best results were obtained when using 75% feldspar + 25% bio or 50% feldspar + 50% bio, as well as 1 or 1.5% potassium spraying. No significant differences due to use 75 or 50% feldspar + 25 or 50% bio or potassium citrate 1% or 1.5%. Therefore, from the results of the study, we recommend that treating date palm trees with 50% feldspar + 50% bio or spraying dates with 1% potassium citrate to obtain a high yield with good properties, hence high value marketing.
