Abstract

A field experiment was carried out at Balouza North Sinai Research Station, Desert Research Center, to study the effect of application of P and Si on wheat productivity growing in the winter season of 2018-2019. The design of the experiment was a factorial randomized complete block design with two factors in three replicates. The first factor was the P fertilizer and the second one was the Si foliar spray. P treatments were P1 = 60kgPha-1, P2= 30kgP ha-1 applied as soil application +30 kgP ha-1 applied as foliar application and P3= 45kgP ha-1 applied as soil application +15 kgP ha-1 applied as foliar application. Silicon was applied in the form of potassium silicate at three rates as follows, S1 (0 mgL-1); S2 (500mgL-1); and S3 (1000mgL-1). At maturity , wheat plants were harvested on 9/5/2019. Grain and straw yields significantly increased by the application  of P and Si . Also, the obtained results showed that N, P, and K contents in grains and straw increased with increasing the application P and Si.
