Abstract

Two field experiments were carried out at Ismailia Exp. Sta., Agric. Res. Center, Ismailia governorate, during 2007/2008 and 2008/2009 seasons to study the influence of zinc application on growth, yield and yield components of some wheat (Triticum aesitivum L.) cultivars (Sakha-93, Sakha-94, Giza-168, Gemmeiza-9 and Gemmeiza-10). Three levels of Zn were applied: 0.0 (control), 1.5 and 3.0 kg Zn per Fed. Results showed that positive significant effects on growth traits, grain yield and its attributes was achieved by fertilizing wheat cultivars with 3.0 kg Zn/fed. Also, application of 3.0 kg Zn/fed. showed the highest values of P, K, Zn and Fe of shoot content. The largest flag leaf area was that of Sakha-93 and Gemmeiza-9 while, Giza-168 had superior shoot dry weight.  Sakha-94 cultivar significantly surpasses all cultivars in plant height, while Gemmeiza-10 gave the highest number of spikes/m2, while 1000-grain weight of Sakha-93 was the largest. The highest grain yield was achieved with Sakha-94 and Gemmeiza-9.
