| Abstract | ||||
| Zinc deficiency is a common problem in Egypt that can cause poor growth and increase the susceptibility of wheat to various diseases. Therefore, it is important to explore ways to overcome this issue and improve the quality of the wheat produced in the country. The field experiment conducted on two bread wheat cultivars (Giza-168 and Giza-171) at the Agricultural Research Station in Bahteem, Qalyubia Governorate, Egypt showed promising results. Four treatments were performed: 1) control /tap-water only, 2) one Zn-spray at 45 days after sowing, 3) one Zn-spray at 60 days after sowing, and 4) twice Zn-sprays at 45 and 60 days after sowing. The spraying solution was prepared using ZnSO4.7H2O at a rate of 5g/l tap water/ spray (200-250 l/spray/fed). Results revealed that the yield and some of its components of both studied varieties showed increments. Most of these increments were statistically insignificant, except in the case of Giza-168, where both the yield and number of spikes/m2 in the first and second seasons were significant. These were achieved by spraying wheat plants with Zn 45 days after sowing (during tillering stage). The results, also, indicated that spraying wheat plants with Zn significantly increased grain-Zn concentration. Generally, Spraying wheat plants twice (at 45 and 60 days after sowing) should be recommended | ||||
