Effect of sowing method, micronutrients and nitrogen fertilizer levels on wheat yield under sandy soil conditions [electronic resource].

Includes references.

Two field experiments were carried out at the experimental farm, Fac. of Agric., Zagazig Univ., Egypt, during the two successive seasons of 2007/2008 and 2008/2009 to study the effect of three sowing methods (Broadcasting, drilling and cross rows), five micronutrients treatments (control, Fe, Zn, Mn and Fe + Zn + Mn) and three nitrogen fertilizer levels (35, 70 and 105 kg N/fad) on yield and its attributes of wheat cv. Sakha 93. A split-split plot design with three replications was used. The most important results could be summarized as follows: 1. Broadcasting method produced the highest values of number of grains/spike and straw yield ton/fad, whereas, cross rows method produced the highest values of number of spikes/m2 and grain yield ardab/fad. In addition, 1000 grain weight of wheat was insignificantly affected by the different sowing methods. 2. Application of Zn led to a significant increase in 1000~grain weight, grain yield and biological yield. However, application of Fe + Zn + Mn in combination resulted in the highest values of straw yield ton/fad. Number of spikes/m2 was insignificantly affected by micronutrients treatments. 3. All studied characters gradually increased by increasing nitrogen fertilizer levels from 35 up to 105 kg N/fad. 4. Drilling method interacted strongly with Zn or combination of Fe + Zn + Mn to increase grain, straw and biological yields ton/fad in wheat fields. Keywords: Wheat, sowing methods, micronutrients, nitrogen fertilizer levels.
