| Abstract | ||
| An experiment was conducted during the two growing seasons 2017 and 2018 seasons to study the impact using of nano N fertilizer compare to conventional form on the growth, yield, and nutritive value of the fruits of Zaghloul date palm grown under Qena, Egypt condition. Nano N fertilizer was added at 20, 40, 60, and 80% of the recommended dose. Two methods of application, soil surface, and foliar spray were used to applied nano fertilizer form. It is evident from the obtained results that using nanotechnology N fertilizer was very effective in improving growth and yield as well as fruits quality compared to using the conventional form. Supplying Zaghloul date palm by 20 % of recommended N dose in form of nano fertilizer led to a significant decrease in all studied traits. Raising the dose of N nano to 40% of recommended dose failed to show significant differences compared to control. While raising the dose from nano N to 60% led to a significant increase in all studied traits. However, increasing the dose from 60 to 80 % of recommended dose led to a non-significant increase in all studied characteristics. On the other hand, the spraying method surpasses adding via soil in traits of vegetative growth, while there are no significant differences between different methods of application in the other studied traits. From the economic point of view, this study recommends using N fertilizer in nano-form at the rate of 60 % of recommended dose via soil surface in fertilization of Zaghloul date palms. | ||
