N2  - The present study was carried out at Shibeen El-Qanater, Kalubia governorate, Egypt during two successive growing seasons of 2001/2002 and 2002/2003 to identify the effect of urea solution 2% N and some organic manure extracts (pigeon manure, chicken manure and biogas manure) with a ratio 1: 12 manure: water as a foliar application on wheat yield (Gemmeza 5, Triticum aestivum L.) and its components. Manure extracts were applied in 4 equal doses (600 L fed⁻¹) at 20,40,60 and 80 days after cultivation, while urea solution (600 L fed⁻¹) was applied in equal two doses at 25 and 50 days after cultivation. A basal dose of urea fertilizer at rates of 25 and 75 kg fed-I in the form of urea 46.5% N was also added as soil application. Results revealed that the plant height, grain & straw yields and 1000 grain weight exhibited significant increases as a result of application studied treatments, in addition to a significant difference between wheat yield and its components at a basal dose of N (25 or 75 kg urea fed-I). Also, the results showed that the positive effect of pigeon manure on wheat yield and its components surpassed the other organic manures. The NPK uptake by wheat plants were more pronounced at the applied treatment of pigeon manure, while the least one was urea spray at 2% N. As for the micronutrients (Fe, Mn and Zn) uptake by wheat plants, data indicated that the biogas manure extract surpassed the other organic manure extracts
