| Abstract | ||
| The present study was conducted in a private orchard at Abi El-Khassib District, Basrah Governorate during the growing season of 2012 on date palm trees Phoenix dactylifera L., cv. Barhee aged 15 years old to investigate effect of spraying seaweed extract" Kelpak " at concentrations of (0 and 8 and 16) cm3.l-1 and NPK fertilizer at concentrations of (0 and 4 and 8) gm.l-1 and their combinations on some fruit ripening parameters and yield components of the tree. Results showed that spraying treatment of 16 cm3.l-1 Kelpak recorded significant increases in fruit respiration rate at Kimri and Khalal stages , fruit ripening percentage at Khalal stage, total yield of the tree, fruit weight of bunch , total bunch weight and number of fruits per strand at Tamir stage. Spraying treatment of 8 cm3.l-1 Kelpak recorded significant increase in fruit ripening percentage at Rutab stage. Spraying treatment of 0 cm3.l-1 Kelpak increased fruit respiration rate significantly at Tamir stage. Spraying treatment of 8 gm.l-1 NPK fertilizer increased fruit respiration rate significantly at Kimri and Khalal stages , fruit ripening percentage at Khalal and Rutab stages, total yield of the tree, fruit weight of bunch, total bunch weight and number of fruits per strand at Tamir stage. Spraying treatment of 0 gm.l-1 NPK increased fruit respiration rate significantly at Rutab stage.The bi-combination of spraying Kelpak at the concentration of 16 cm3.l-1 and spraying NPK at the concentration of 8 gm.l-1 recorded significant increases in most of the studied parameters as compared to other bi-combination treatments | ||
