Abstract

Two pot experiments were carried out during the two successive Winter seasons of 2015/2016 and 2016/2017. The
experiments were executed in a private commercial nursery located at Damanhour City, El-Beheira Governorate, Egypt
under greenhouse conditions. The objective of this research was to evaluate the effect of silicon (Potassium silicate; Si) as
a spray, or a soil drench at concentrations of 0, 5 and 7.5 mmol in enhancing Narcissus tazetta L. growth, flower
production, and quality. The experiment was conducted as a split-plot in a randomized complete block design (RCBD).
The obtained results of the two seasons, generally, showed that application of silicon as soil drench at 7.5 mmol recorded
the highest mean values of the most data recorded and might be considered as optimal treatment for the production of high
yield and quality of narcissus plants under the environmental conditions of Beheira Governorate and other similar regions.
